Foundational Concepts Review - BEHA 5455

Using Ration Schedules Effectively

1 Select Schedules to sustain desired rates -Individualizing schedules, reducing rates 2. Thin gradually- 3. Consider ongoing reinforcement schedules prior to implementing Extinction to reduce problematic behavior

Differential Reinforcement of Low Rates (DRL)

Reinforcement delivery when the number of responses in a specified period of time is less than, or equal to a predetemined set limit.

Stimulus Overselectivity

Responding exclusively to just one among a complex set of stimuli regardless of variations in stimuli and contingencies in effect

Overgeneralization

inappropriate generalizations

behavioral momentum

making requests known to promote high rates of compliance in advance of the activity less likely to be performed

examples of tacting

"I"m hungry" "I"m sad" "My tummy hurts"

Fixed Interval Scallop

A fixed-interval schedule often produces a scallop: A gradual increase in the rate of responding, with responding occurring at a high rate, just before reinforcement is available. No responding occurs for some time after reinforcement.

What are the advantages of Changing-Criterion Design?

As with the multiple-baseline design (Chapter 9), it does not require a reversal phase to demonstrate experimental control

with Fix ratio schedules:

Note that with the fixed ratio schedule, a pause sometimes follows the completion of a ratio, after which rapid responding begins again. This pattern of FR responding is called break and run,

Advantage of Stimulus Generalization

Repeating certain behavior under varied stimulus conditions. Whether planned or not it can conserve time, effort, and material resources, big economic means

A feature that describes how correct or valid conclusions are about the functionality of the relationship between two variables, such as an intervention procedure and changes in behavior.

internal validity

Adjusting or progressive schedule

one that decreases or increases gradually as a function of a client's performance

differential reinforcement of high rate (DRH) schedule

restricts reinforcement to a response preceded by rate of responding as in the case of reinforcing only if at least 5 responses have been emitted in the last 2 seconds

Fixed Ratio Schedule (FR) schedule

the responses requirement remains constant

Interreinforcement Interval

the time between reinforcer deliveries

2 echoic training methods

1. shaping 2. incidental teaching

Variable Interval Schedule (VI)

Operate like fixed interval schedules except that the interval required before a response can produce a reinforcer varies. We usually indentify such schedules in terms of the average interval

choral responding

Oral response of students (in unison) to a question or problem presented by the teacher.

Stimulus change

Presenting or withdrawing motivating operations and/or SDrs or SΔs.

Redirection

Taking actions to interrupt inappropriate behavior and prompting the organism to engage in an alternative appropriate behavior.

Disadvantage of Stimulus Generalization

Using our native language in another country. When baby calls another man daddy. making eye contact where not appropriate. Remedying unwanted generalization after the fact adds to cost of changing behavior because than we need to teach new discriminations

Response versus Stimulus Generalization

With this the response of interest does not remain intact as with stimulus generalization but it begins to shift its form or topography

differential reinforcement of paced responding (DRP)

limits reinforcement to those responses that fall within some high and low rate boundary, as when the response is reinforced only when preceded by 5 seconds of responding at a minimum rate of one per second and a maximum of 2

Factors affecting rate of responding during ratio reinforcement after schedules are no longer in effect

size of the ratio requirement the gradualness with which the reinforcement is phased out How fluently the response pattern is emitted

Disadvantages of Interval schedules

the individual may excessively display unrelated behaviors to fill the time between reinforcer delivery. such behaviors are more likely when other reinforceable activities are unavailable during the inter reinforcement interval

Positive behavior interventions accomplish what 3 things.

• Prevent or reduce problematic behaviors • Are less likely to provoke violence, escape and aggression • Are considered more pro-social

Social Reinforcer

-

Disadvantages of DRA

- Effect may be delayed, could take time for the contingencies to take effect. - Other adaptive behavior may decrease in other settings, must make sure to implement procedure across all settings.

How to use DRO effectively.

- Maximize opportunities for reinforcement -Adjust schedule gradually -Combine with other procedures For example: An investigator found that providing a clock assisted children to distinguish when any particular schedules of reinforcement were in effect (i.e. how long they needed to refrain from unacceptable behavior to receive their reinforcers).

Disadvantages of response cost procedure

- Not universally effective: misuse decreases effectiveness - Punitive, non-constructive contingencies - Can suppress acceptable responses

Why vary aversive stimuli.

- You use less intrusive punishers mixed in with more intrusive. - Delay habituation to punishing stimulus.

Advantages of DRL and DRD:

-Benign, both permit reinforcement to continue, thereby sharing many of the advantages with other positive procedures. -Tolerant, both reflect a built in tolerance for the target behavior, communicating the message.

Advantages of differential reinforcement of other behaviors (DRO).

-Widely applicable: DRO is benign and easy compared to the dense reinforcement required of DRA. -Relatively rapid -Often durable and general: often has produces lasting response suppression.

Using Modeling effectively:Managing contingencies

-highlight similarities between models and observer --Encourage behavior rehearsal (preschoolers needed to be shown and told how to share and then requested to rehears or practice the skills to accomplish the goals) ---provide instructions rules an rationales: verbal instructions and rules can increase the effectiveness of modeling --Ensure simplicity of imitative prompt (try modeling someone putting together a complex machine-YOU CANT) --Reinforce the modeled performance: this has been found to increase initiation --Reinforce imitating

Advantages of Alternating Treatment Designs

-permit the effects of one or more independent variables to be compared -long baselines are unnecessary because these designs rapidly reveal distinct differences as a function of each diverse treatment -it permits the variables to be compared within the context of a more slowly changing background, such as seasonal changes, variations in available materials

What are the disadvantages of ratio schedules?

-ratio strain -diminishing performance quality - interval schedules are easier to use

Strategies for Promoting response rates

-reducing or increasing the size of the interval for a while -building a history of reinforcing high or low rates of the response -reinforcing high rates of responding -adding a limited-hold component -using instructions or rules -arranging competitive contingencies -taking advantage of contrast effects -interspersing easy tasks

1. generate high response rates 2. high rates generated initially may continue even when the schedule is shifted to one that is interval-based 3. particularly easy to use when the target response produces a permanent product 4. used to facilitate the transition from artificial to natural reinforcing contingencies

6 reasons peers are effective contingency managers

1. peers have more contact with peers 2. peer-managed interventions are more preferred by clients. 3. peers retain more of what they learn 4. peer tutoring is cost effective 5. peer tutoring is more effective in general 6. peer managers often learn the skills better themselves because of augmented training opportunities

4 types of antecedent manipulations

1. presenting sds that signal reinforcement (SDr) 2. Removing SDs taht signal punishment (SDp) 3. Decreasing the necessary response effort for the desirable behavior 4. Presenting or arranging a MO that heightens the reinforcing value of the consequence of the desirable behavior

Determining experimental significance

1.Trend analysis- 2. time series statistical analysis

Respondent conditioning

when a neutral stimulus (NS) is paired with a US thereby producing

positive behavioral contrast

• Behavior increase without a change in schedule of reinforcement when another behavior decreases due change in rate of reinforcement or schedule of reinforcement.

Advantages of NCR

• Inadvertently strengthens desirable behaviors • Provides higher rates of reinforcement • Easy to implement • Rapidly promotes reduction in problem behaviors

When is redirection not a good idea?

• When the function of the problem behavior is attention, redirection may just reinforce the inappropriate responding. • When the function of the behavior is escape, redirecting to a preferred activity redirection servers as a negative reinforcer in this case.

IOA for Interval Time-Sampling

# of intervals agreed / # of intervals agreed + # of interval disagreed x 100 Scored Interval = only those intervals in which the behavior was scored as occurring are included in the analysis. Used when behavior occurs at LOW rates. Unscored Interval = only those intervals in which behaviror was not scored as occurring are included in the analysis. Used when behavior occurs at HIGH rates.

three disadvantages of timeout

(1) Loss of learning time; (2) legal and ethical considerations (3) public concerns with timeout

Seven safeguards to minimize public reactions to timeout.

(1) combine with other procedures; (2) create as reinforcing a natural environment as possible (3) remove as many reinforcers supporting unwanted behavior as feasible during timeout (4) determine magnitude empirically (5) use the smallest magnitude of aversive conditions found to be effective (6) clearly communicate response cost or timeout conditions (7) use consistently (8) consider delivering response-cost points to a peer (9) avoid opportunities for self-injury, self-stimulation, and escape during timeout (10) monitor implementation and progress (11) design the program to minimize emotional outbursts

two factors that influence the effectiveness of a timeout procedure.

(1) combining it with other procedures (2) creating as reinforcing a natural environment as possible

Advantages of Positive punishment

- Decreasing collateral inappropriate behavior. Other mal-adaptive behavior may decrease along with the target response. - Increases responsiveness to reinforcement. "punishment may enhance the efficacy of reinforcement for establishing appropriate behavior that competes with or replaces inappropriate behavior, an outcome that may lead to the withdrawal of punishment. - Modeling what not to do for peers - May facilitate acquisition of a range of skills.

Advantages of response cost procedure

- Effectively reduces behavior when used correctly - Promotes discriminative learning - Socially acceptable - It is relatively convenient to use

What may cause NCR to be ineffective?

- If the target response has been under Intermittent reinforcement schedules NCR may take a long time to take effect. - Other reinforcers are maintaining the response. - Non functional reinforcers being delivered. - Neurological disorder (tics).

Contextual factors that affect punishment

- Proximity to the punishing stimulus / agent - Punishing agent (mom, stranger, teacher) - Time, setting response takes place - Tiredness, hunger, EO's of the orgnism

Disadvantages of positive punishment

- Punishment can evoke other behaviors (aggression, escape crying). - Suppressing responses. other responses besides the target behavior may decrease. - Learned helplessness

Good Behavior Game

- interdependent group contingency used in combination with modeling, rules, and DRL or DRD to obtain faster results - groups compete against each other by seeing which is able to hold their penalty points below a given limit - the team(s) scoring below the set number, or who have the fewest infractions, win various reinforcers

Behavioral Objective Format

-Problem - Goal, context -Criterion Level - Rate of behavior, rate of criterion, other dimensions of behavior -Behavioral Objective

Disadvantages of DRL and DRD:

-Time, both may take a while to combine with other positive reductive procedures. -Many not be suitable for dangerous objectionable behaviors. -Focus on undesirable behavior, this may poses that preferred behaviors may be overlooked or unwanted ones unduly attended to and thereby be inadvertently reinforced by the extra attention.

Advantages of changing criterion design

-does not require a reversal phase to demonstrate experimental control (very good when dealing with irreversible behaviors) -can demonstrate experimental control with a single individual behavior or within one setting -suited to programs in which criteria are changed gradually and progressively as in DRD or DRH or DRL

Disadvantages of Changing Criterion Design

-each phase acts as a baseline for the next -long phases if behavior is slow to change or stabalize -it requires control over both directions and level of change -losing experimental control due to behavior's progressing more rapidly than anticipated to the desired end level

Disadvantages of alternating Treatment desgins

-sequencing effects -is that its participants may fail to discriminate between conditions that are rapidly alternating

Social validity

-social significance of the goals -socially appropriateness of the procedures -social importance of the effects

Using and demonstrating Control Via the Changing-Criterion Design

-the different component can be adjusted by varying length of the phases, the magnitude of change demanded by the criterion levels, and the number of phases -the varying lengths of each phase increases the design's validity

Advantages of interval schedules

-their ease of implementation is major. They are duration rather than frequency based -They delay satiation because they are intermittent schedules of reinforcement. this is probably responsible for maintained responding during reinforcement -Although FI tend to produce changing response rates (scallops) variable interval schedules promote more consistent responding

example of Multiple Probe Design

1 of three children learning laundry skills. The probes measure each response in the entire chain right before the baseline and training of each component. no reinforcers were delivered during probes. the baseline data only measure components previously trained, plus as teh data indicate the component to be trained next.

How to use differential reinforcement effectively to develop stimulus control

1. reinforcing the appropriate response in the presence of SD 2. Not reinforcing in the presence of other stimuli *Must be maintained because if they are not, stimulus control may weaken or disappear.

Using physical guidance effectively

1. secure the client's cooperation and keep guidance to a minimum 2. help learners attend as well to proprioceptive cues-the stimuli or sensations that arise from within their own bodies 3.

7 Steps in using Direct Instruction (DI)

1.Follow a very carefully organized and detailed sequence of instruction. They Follow scripts to ensure that material is presented properly and followed with appropriate consequences. This minimizes problems with instructional demand and supports delivery of merited reinforcement 2. Teach in small groups as appropriate 3. Prompt unison group (coral responding 4.

Task Analysis

An analysis of complex behavior and sequences of behavior into their component responses, looking at the process not just the final product

Functional Assessment

An assessment of the contingencies responsible for problem behaviors

Establishing Operation

An environmental change or event that precedes the response to which it is functionally related and increases the effectiveness of a particular stimulus change as reinforcement

Motivating Operations

An environmental variable that (a) (value-altering) alters (increases or decreases) the reinforcing effectiveness of some stimulus, object or event. Ex: a hungry child will eat. and (b) (behavior-altering) alters (increases or decreases) the current frequency of all behavior that have been reinforced by that stimulus, object, or event.

S-Delta

An extinction stimulus and tells us that reinforcers will not be available. Ex: Someone talking

Links

An inapt response that combined with others form a behavioral chain; small teachable units that may configure a series of sequentially ordered links within more complex behavioral chains.

Positive Reinforcement

An increase in the rate or probability of behavior is a function of the frequency with which that behavior is reinforced. In positive reinforcement, the organism gains a stimulus, dependent or contingent on a response, resulting in the rate of that response increasing or maintaining.

social stories

An instructional technique in which students create or interpret narrative or visual illustrations that reflect typical social encounters. are a specific antecedent strategy designed to enable children to better follow a particular social protocol

Permanent Products of Behavior or Outcome Recording

An observational method based on assessing durable products of behavior. The evidence remains intact.

Variable Ratio (VR)

An operant conditioning principle in which the delivery of reinforcement is based on a particular average number of responses. (e.g., on a VR 10 schedule an average of 10 responses must be emitted for reinforcement, but the number of responses required following the last reinforced response might range from 1 to 30 or more). VR schedules do not produce a "Postreinforcement Pause". They create high & constant rate of responding. Behavior becomes most resistant to extinction.

Free Operant

Verbally Controlled or rule-governed behavior

Behavior under the control of as rules and instructions, rather than behavior shaped by reinforcing or aversive consequences. Because it covers a broader array "rule-governed behavior" generally has been replaced by the term "verbally controlled"

Unconditioned Respondent Behaviors

By directing aversive comments at the organism instead of at the target response. e.g., You'r an awful child! Vs. No Hitting! Hitting is awful!.

Contextually inappropriate behavior

CIB or behavior unsuitable in the particular context, Describes classes of behavior that might reasonably be targeted for reduction given specific circumstances

Mand

COMMAND A verbal response in which the form of the response is controlled by an establishing operation A request. Asking for something. Function: Gain access to item

Examples of Motivating Stimulus

Cannot drive car unless you have your keys but you have lost it. You look in all familiar places until you find it. When you wanted to drive the key became the reinforcer-hunting for it was evoked by those circumstances (this is a S M) Hunger is the MO-and a bowl of hot soups is served minus the spoon (SM). The individual must request the spoon or locate to eat. Or putting puzzle to together and find the piece (SM) is missing. He must request or find that piece to finish

Functional Communication training

Car and Durrand developed a procedue to rectify maladaptive behavior. It can be viewed as an application for mand training Involves using DR to teach people to mand in a socially acceptable way for the same reinfocer that historically served to maintain problem behavior

response cards

Cards, signs, or other items that are simultaneously held up by all students to display their response to a question or problem presented by the teacher; response cards enable every student in the class to respond to each question or item.

Schedule Thinning

Changing a contingency of reinforcement by gradually increasing the response ratio or the extent of the time interval; it results in a lower rate of reinforcement per responses, time, or both.

involving successive changes in the criterion for delivering consequences, usually in graduated steps from baseline levels to a desired terminal goal.

Changing-Criterion Design

Fixed Interval

Checking the oven to see if cookies are done when the cooking time is known (i.e., they won't be done until that time is up).

Fixed Interval

Checking your mail when you know the mailman comes every day at 1 PM.

Using Modeling effectively by choosing models

Choose models who: --share common characteristics of observe --are competent in the skill to be imitated --have initially experienced difficulty learning the skill (coping models) --have had previous positive interactions with the observer --are prestigious (receive above average reinforcers from peers and supervisors --select multiple models

Example of VI

Chuck's teacher would have varied the interval from 0-10 minutes when she prepared the clock to prompt the reinforcement. Eventually these intervals would have averaged about 5 minutes. it would then be called VI 5 minutes or Variable interval 5 minutes

Operant Classes

Classes of Responses that are affected by the way in which they operate on the environment. No two responses are identical, so we speak of a class of R that produce similar effect on the environment.

Describe the activity table

Rational task analysis

Components of a task analysis derived from studying the subject matter and specifying the process or procedure that is presumed to be involved in performing the task.

Learning

Consists of altering response patterns, generally as a function of changes in environmental conditions. Learning = behavior change. The way we know an organism has learned something new is by observing changes in patterns of behavior in relation to particular environmental events.

Advantages of DRA

Constructive: Better to increase appropriate response than decrease inappropriate responses Benign: unlike extinction, response cost and timeout, DRA procedures continue to deliver reinforcers. Acceptable: more socially acceptable than other procedures. Lasting change: Once the target response stops, if the alternative is maintained the target response is not apt to return.

Using DRH to promote high responding

DRH is designed to promote consistently rapid responding. To establish DRH we very close watch sequences of responding and deliver reinforcers only when several responses occurring in rapid succession at or above a pre established rate

what is meant by non-contingent delivery of reinforcers (NCR).

Delivery of reinforcers to the environment independent of the participant's behavior. These conditions are maintained on a FT or VT schedule.

Why is caution necessary when combining NCR with other interventions like DRA.

Dense schedules of NCR may make other interventions / schedules of reinforcement less effective.

Reactivity

Describes the way the assessment procedures themselves (not any treatment or intervention) affects the clients temporary, initial reaction to being observed.

Backward chaining

Developing a behavior chain of responses by reinforcing the last response, or link in the chain, until the entire chain is emitted as a single complex behavior.

Forward chaining

Developing a chain of responses by training the first response or link in the chain initially. Then joining the entire link together until the entire chain is emitted as a single complex behavior.

cumulative record

Displays rates of some event (usually a response), in the form of changes in the slope or curve of the record as a function of conditions in effect.

To qualify as a true ABA program,

Each single case application must be accompanied by graphic displays of the impact of the specific intervention. Additionally, before any treatment is deemed to produce a particular result reliably, it must demonstrate that outcome in the form of multiple replications either across different behaviors within the same individual or across different individuals or groups

Analytical

Emphasis on demonstration of functional relationships OR the ability to control the occurrence and non-occurrence of the behavior Ex. The relationship between off task behavior (behavior) and teacher giving him attention (consequence)

How to reduce, remove, or override competing contingencies

How to: Reinforce appropriate behavior of client AND natural/competing contingencies

Three Functional Assessment Strategies

INTERVIEW: talk to the person with the behavior problem and those who interact with and have direct contact with that person OBSERVE: observe the person in his or her daily routines for an extended period of time INTERVENE: present, remove, or modify the contingencies that may be reinforcing the problem behavior

Dead-man Test

If a dead man CAN do it, it probably is NOT behavior If a dead man CANNOT do it, it probably is behavior

Response deprivation hypothesis (RDH)

If access to one of a pair of events is restricted below free operant levels (baseline of naturally ongoing behavior), an organism will work to regain access to that activity. In other words, if access to a reinforcing activity is restricted, admission to it becomes more reinforcing as a function of the deprivation conditions in effect.

What are the benefits of activity schedule?

Improve transitions between activities. Warning signal for event change. Reducing problem behavior.

four variations of time out categorized by Ryan, Peterson, and Rozalski (2007).

Inclusion timeout Exclusionary timeout Seclusion timeout Restrained timeout

Advantage of Independent group contingencies

Independent group contingencies permit each individual to profit regardless of the performance of other individuals, however peers have no incentive to try supportive or coercive tactics to influence another.

Behavior Analytic Procedures

Interventions or treatments used to induce behavioral change (e.g., the application of behavioral principles). Behavioral procedures, or strategies, are used to occasion, teach, maintain, increase, extend, restrict, inhibit, or reduce behaviors and constitute the core of most applied behavior analysis program.

Differential reinforcement of alternative behaviors (DRA)

Involves reinforcing ANY alternatives to the unwanted behavior, while treating or withholding reinforcement from the unwanted behavior. For DRA to be effective, must identify and withhold all sources or reinforcement positive & negative from the problem behavior.

Positive Punishment

Involves the presentation of some stimulus contingent on behavior and results in a decrease in the future likelihood of that response. Example: Spank a child

Negative Punishment

Involves the removal of some stimulus contingent on behavior and results in a decrease in the future likelihood of that response. Example: Remove favorite toy

SM (Motivating Stimulus)

Is a stimulus that must be present to allow the individual to engage in the behavior that is primed for reinforcement. Its absence evokes seeking out that stimulus.

Differentiate between motivational operations, discriminative stimulus, and other antecedent events.

MO: antecedent events that change the value of the consequence or along with the immediate SD may alter the behavior. SD: antecendent's that influence given subsequent behavior. Either evoke or abate the occurrence of behavior. SDr: A stimulus which a given response is likely to be reinforced. SDp:A stimulus in which a given response is likely to be punished. S-Delta: A stimulus in which a given response does not produce reinforcer's.

How to use DRO effectively

Optimize reinforcer delivery. Set the DRO t to just below baseline interval lengths. combine with other procedures. Adjust schedule gradually.

Matching Law:

Organisms distribute their behavior between two or more concurrent schedules of reinforcement. Ex: If a behavior is reinforced 60 percent of the time and in another it is 40 percent, that behavior tends to occur about 60 percent of the time in the first situation and 40 percent in the second.

Explain the risks involved in "modeling punishment".

Others may duplicate the act of delivering punishment. e.g., Mom hits dad playfully, daughter hits brother in the face BLAM!.

PUN

How can response cost procedures be abused.

Particularly when frustrated, contingency managers may be tempted to apply those methods more frequently or restrictively than necessary.

Advantage of dependent group contingencies

Peers have often been noted to attempt to influence three performance of other group members, by showing or telling them what to do. One drawback to such group contingency is that in the absence of further rules the pressure extended by pees may be negative or coercive (bullying).

Discuss why it is not effective to increase the cost in a response cost procedure by small increments.

People adapt more to gradually to increasing intensities of punishment. Implementers should return to baseline for awhile and then increase the magnitude of the procedure.

4 Successful reinforcement applications

Quality, Quantity, immediacy, schedule(continuous,intermittent)

Restricted Operants

Rate of responding is determined by opportunities to emit the response The response can only be made if the experimenter does something They are to be contrasted with free operants

Progressive Ratio (PR)

Ratio Schedule in which the ratio size gradually increases over time. This schedule is sometimes used to assess reinforcer effectiveness. To do so, the "break point" is identified - when the organism stops responding.

Contingency

Refers to the specified dependencies or relations between behavior and its antecedents and consequences.

Punishment or Reinforcer? Child spits, dad says, "No spitting!" child spits again

Reinforcement

Differential Reinforcement of Diminishing Rates (DRD)

Reinforcement is provided at the end of the predetermined interval contingent on the number or responses emitted during the interval being fewer than a gradually decreasing criterion based on the individual's performance in previous intervals.(e.g. girls talking in class; fewer than 5 occurrences in 5 minutes .. , then 4 in 4 ... ). DRD is a procedural variation of DRL (provides ABA with new and improved label for internal DRL procedures).

Progressive Schedules of Reinforcement

Reinforcement is thinned independent of the performance of the learner at a predetermined rate.

Fixed Ratio (FR)

Reinforcement occurs at fixed response intervals: (FR 5 = giving reinforcement after every fifth response). Skinner called them response units (all 5 combined).

Partial/Intermittent Reinforcement

Reinforcement schedule in which a reinforcer follows the response only once in a while

Punishment or Reinforcer? Child spits, dad says, "Cool, did you see that?" child spits again.

Reinforcer

Fixed Time Schedule (FT)

Reinforcer delivery is not contingent on specific behavior. Reinforcers were delivered regularly after a fixed or constant time period regardless of the ongoing behavior. It can be risky because while the schedule is in effect the only condition stipulated for the delivery of reinforcers is the passage of time.

SD s versus MO s

SD's evoke maintain and increase or decrease responding depending upon consequences for responding that they signal MO s maintain, increase or decrease the effectiveness of the reinforcers or punishers

Different categories of discriminative stimulus

SD= discriminative stimulus S-delta= discriminative stimulus for extinction: signals that the response is not likely to produce a reinforcer SDr (discriminative stimulus for reinforcement) = signals that in its presence, a given response is apt to be reinforced SDp= discriminative stimulus for punishment: in the presence of that particular stimulus, a given response is likely to be punished

Reprimand

Scolding, etc. Can be a punisher, but depends on the context. Delivering a reprimand starts a vicious cycle of behavior. The parent can make the behavior stop, but has to keep delivering reprimands.

Secondary or learned reinforcers and secondary aversive stimuli.

Secondary or learned reinforcers are stimuli that acquire their reinforcing properties only as a function of events in the individuals life. Secondary aversive stimuli is the removal or prevention of which also becomes a reinforcing event.

The Sick Social Cycle (Victim's Punishment Model)

The perpetrator's aversive behavior punishes the victim's appropriate behavior, and the victim's stopping the appropriate behavior unintentionally reinforces that aversive behavior

Speaker

Response Dimensions

The physical properties of a response Examples: Topography, Latency, Duration, Pitch, Force..

Primary aversive stimuli

The prevention of what is reinforcing, regardless of prior learning

Reinforcement

Reinforcement is used in what ways?

To change behavior To increase behavior To maintain Behavior the contingent relation between the behavior and the stimulus affecting it An observable natural event

Purpose of a Functional Assessment

To determine the probable function the behavior serves to develop a behavior intervention plan composed of preventative measures

four purposes for collecting baseline data

To display actual current levels of performance. To serve as a basis for predicting future levels of performance To enable us to assess the durability of change in response pattern To decide whether to reinstate, and perhaps permanently install or slowly phase out the intervention.

When to use Continuous reinforcement

To increase or stabilize a behavior, but not for maintaing over a long period of time

a single-subject or intensive experimental design that involves: 1) collecting baseline measures on the same behavior of several different individuals;2) applying the intervention first with one individual while the baseline conditions are continued with the other individuals; then 3) applying the intervention to the second individual's behavior as in item 2. This procedure is continued until it becomes apparent that individual's behavior systematically changes only when the intervention is applied.

Across-behavior multiple-baseline design

a single-subject or intensive experimental design that involves: 1) obtaining a validly representative set of pretreatment measures (baseline) of several different behaviors; 2) applying the intervention or experimental procedure to one of the behaviors until its measurement pattern changes substantially, while continuing to record the baseline measures of the other behaviors; 3) applying the identical intervention to a second behavior; then to a third and so on. The procedure continues until it becomes apparent that each behavioral measurement changes concurrent with the intervention.

Interresponse Time (IRT)

elapsed time between two successive responses (a measure of temporal locus). Long IRT produce low rates of response, while high IRT produce high rates of response. Examples: 1. DRH schedule produces reinforcement when response occurrs before a time criterion of 30 sec. Thus, response gets reinforced when IRT is 30 sec. or less. 2. DRL produces reinforcement when occurring after a set time critterion (45 Sec.) Thus, a response produces reinforcement when IRT is at least 45 sec.

Overall Number of Criterion Changes

it can vary the more often measures of the behavior change conform closely to the new criterion, the more convincing the demonstration of experimental control

Advantages of delayed prompting

reflexivity (identity matching)

match items to themselves (A1 to A1 from an array of samples)

matching law

matching or distributing responses according to the proportion of pay off (usually studied in conccurent schedules) response rate and reinforcement rates should always match

Disadvantages of stimulus change

may prove unreliable on any particular occasion because other factors readily alter the affect. even when stimulus control over a given response is well established, presenting or withdrawing antecedent stimulus will not necessarily turn the behavior on or off Depending on the learning history of the individual, SD s simply set the occasion for certain responses. The antecedent stimulus derives its strength from a prior history of reinforcement, extinction, or punishment of the responses emitted in its presence (bright light always changes pupil, ringing of the telephone do not necessarily produce a learned reaction every time. is the contingency managers are not always in the position to arrange each and every stimulus that may set the occasion for a desired response

Parameters

number of times behavior repeated per specific period of time

Tangible reinforcers

objects such as gloves and gold stars, bonuses and trophies.

Differential reinforcement (DR)

of a discrimminated operant class- 1)reinforcing appropriate response in the presence of stimuli and 2)not reinforcing it (i.e. extinguishing and/or punishing it in the presence of others

Concept

one or a set of abstract critical properties shared perhaps only in part among a number of critical antecedent stimuli. For Example: Our concept of a Dog is that is has four legs, they bark, and they are in certain colors and/or shapes.

Scatter Plot

one variable usually time of day is plotted on the ordinate (y axis) and a second variable usually days, is plotted on the absiscca (x-axis). May help to identify elusive enviornment stimuli.

Sequence carryover

or alternating effects all refer to situations in which one experimental treatment influences behavior within other treatment phases

Y-axis

ordinate

Matching Law

organisms distribute their behavior between two or more concurrent schedules of reinforcement ( ie. if the behavior is reinforced about 60 percent of the time in one situation and 40 percent in another situation, the behavior tends to occur about 60 percent in the first and 40 percent in the second)

fixed ratio

paid for each chore completed

post-reinforcement pausing

pause in responses that occurs after reinforcement; appears more as FR becomes higher

overcorrection

positive punishment in which, contingent on a response, the learner is required to engage in effortful behavior directly or logically related to fixing the damage caused by the behavior.

Avoidance

postpone an aversive stimuli

Differential reinforcement of Incompatible behaviors

procedure designed to increase the rate of a behavior that cannot coexist with the one targeted for reduction.(E.g., reinforcing completion of work reduces those forms of disruption that are incompatible with working.)

most to least

progressing the prompt hierarchy from: hand over hand, hand to wrist, hand to elbow, model, gestural, independent

variable interval

radio plays your favorite song, but when it plays is unknown

spontaneous recovery

reappearance of the extinguished response at the beginning of a new session, despite no resumption of reinforcement.

video self modeling

recordings of the clients' optimal behavior are extracted and used as the model to be imitated (student is recorded and the tape is edited to take out weak or external prompts. only great performance is left) this difference self modeling from self observation.

partial interval

records that behavior occurred at any point/time during the recording interval

whole interval

records that behavior occurred during the entire recording interval.

Satiation

reduction in effectiveness of a reinforcer with repeated presentations or with consumption during continued availability (Example: continued consumption of food)

Habituation

reductions in the respondent (reflexive) responding elicited by a stimulus over repeated presentation. (Example: the startle response to a loud noise diminishes with repeated presentation). Term primarily used in respondent or classical conditioning.

Adaptation

reductions in the responding evoked by an antecedent stimulus over repeated or prolonged presentations. (Example: when the client no longer reacts to the presence of the observer). Term primarily used in operant learning.

time delay

refers to the amount of time between the delivery of the sd and onset of a prompt

continuous reinforcement (rate of performance & extinction)

reinforcement every time the behavior occurs; produces a steady rate of behavior because reward is always available so there is no motivation to increase performance; extinction is fast

Differential Reinforcement of Diminishing rates (DRD

reinforcement is delivered explicitly when the number of responses in a specified period of less than or equal to a prescribed limit. Ex: reinforcing at the end of the interval if raising your hand was less than or equal to the criteria.

Differential Reinforcement of High Rates (DRH)

reinforcement is delivered for rates of responding ABOVE a specified predetermined criterion (based on the individual's performance in previous intervals). (e.g., more than three responses per 5 minutes).

automatic reinforcement

reinforcement that occurs independent of the social mediation of others and is produced by the response itself

Whole-interval DRO

reinforcer delivered following a period of time the organism did not engage in the target behavior.

Momentary DRO

reinforcer delivered if the organism is not engaging in the response at the moment the interval terminates.

Differential reinforcement of low rates (DRL)

reinforcer is delivered if a certain amount of time has past since it last occurred. e.g., DRL 5-minute procedure, an organism would be reinforced for emitting a response at 5:01 if the response did not occur during the 5 minute interval.

Variable-Ratio (VR)

reinforcers are also contingent on a number of responses, but the particular number on any occasion varies. Usually VR schedules are identified by the average, ie. VR 20 will on the schedule be reinforced one out of every 20 responses

Socially mediated reinforcers

reinforcers delivered by another person

Supplementary reinforcer:

reinforcers used to augment the natural reinforcers to help bridge the time gap before the natural reinforcer is delivered. They are des9gned to signal that a stronger reinforcer is forthcoming.

Differential reinforcement of alternative behaviors

reinforcing any alternative to the unwanted behavior, while treating or withholding reinforcement from the unwanted behavior.

Response effort

relates to the amount of force, exertion or time requisite to engaging in a response. Other factors being equal we can avoid problematic reactions by temporarily removing the aversive properties inherent in eh response requirement

baseline

repeated measures of the strength of level of behavior prior to the introduction of an experimental variable. Baseline measurements are continued until performance has stabilized and can be used as a basis for assessing the effects of the intervention or experimental variable.

Replication

repeating of experiments to which scientists determine the reliability of their findings and to discover mistakes

Echoic (duplic category)

repeating the verbal behavior of another person, as in parroting what another has said (when I say "icky" and 1 year old says "Icky"

Functional consequences

responses providing people with effective positive reinforces or ridding them of aversive stimuli

fixed interval schedule

set amount of time for intervals; see scalloping pattern where behavior only occurs at the end of the interval

concurrent schedule of reinforcement

set up contingencies of multiple schedules at once so subjects can chose which one they prefer (i.e. which one best suits their learning)

Reinforcer preference assessment

several items are repeatedly presented in counterbalance order and observer records which items are approached, chosen, spend most time with

progressive DRD

size of the interval between responses lengthens or the maximum number of responses within the interval decreases gradually.

variable ratio

slot machine pays off every few pulls, but which pull is unknown

4 major classes of reinforcers

social edible tangible activity

Activity Schedules

specify in words or pictures or display in pictures the daily sequence of activities the student or client is to complete by the time a cue is provided to signal the change of an activity

behavioral goal

state the direction and level to which the target behavior is to be changes.

Primary reinforcers

stimuli that functions as a reinforcer the first time it occurs without any prior learning history

example of Changing Criterion design

stopping a 23 year old male graduate student's smoking after having smoke 20-30 cigarettes a day for several years. He and analyst agreed that if he smoked more than 15 cigarettes a day he would tear a dollar bill into tiny pieces and throw it away. THis criterion remained in effect for five days. Then it was lowered to 13 for five more days and so on. Each 5 days phase acted as a baseline for the next 5 days phase and demonstrated that the self imposed consequence of tearing the bill up was effective.

extra-stimulus prompts

such as modeling, response delay, and or gestures and graduated guidance

Positive behavior interventions

systematic use of scientific principles emphasizing supporting or reinforcing apprpriate behavior instead of punishing inappropriate behavior

Distinguishing between Fixed Interval and Fixed Time Schedules

take care not to assume that an FI schedule is in effect just because reinforcers are being dispensed regularly. For a schedule to qualify as FI reinforcers must be contingent on a given response that follows the end of the Fixed interval. reinforcer delivery is contingent on a specific behavior

mastered

target which results in a correct probe after a 5 day hold.

maintenance

targets that have met the mastery criteria, and after the 5 day hold the target is probed, and results in a correct response. These targets are referred to as being on ___________.

behavioral contrast can:

temporarily alter the rate of responding under interval schedules especially when direct acting strategies are impractical

response effort

the amount of force, exertion, or time requisite to engaging in a response. We can avoid problematic rections by temporarily reducing the level of the demand

unconditioned motivating operation (UMO)

the antecedent value-altering effect of the reinforcer does not depend on one's learning history

Physical guidance

the appropriate body part or parts are physically guided through the proper motion by another person

Reinforcement Procedure

the change agents planned presentation of positive reinforcers or removal of adverse stimuli, as a function of a given response for the purpose of increasing the future behavior

conditioned motivating operation (CMO)

the effect of an antecedent depends on learning history

Conditioned Motivating Operation (CMO)

the effect of an antecedent depends on learning history-the person has learned that that a certain task results in failure

Unconditional Motivating Operation (UMO)

the effect of the reinforcer doesn't depend on prior learning history. (ie if you have just ate a huge meal than eating in producing satiation is UMO that decreases the reinforcing value of food

latency (definition)

the elapsed time from the onset of a stimulus, until the initiation of the response. works best for measuring behaviors that are important to occur within some specified time from a signal. (responding to greetings, changing class when the bell rings).

Changing Criterion Design

the experimenter successively changes the criterion for consequation, usually in graduated steps, from baseline levels to desired terminal level. a step wise introduction of different criterion values above or below baseline. The steps consists of progressive increases or decreases in the response requirement If the behavior changes successively at or close to the set criterion levels, experimental control can be demonstrated

target

the first step of behavioral assessment is: identify the ______ behavior

transitivity

the individual will be able to choose appropriatley given ordered matches that share a common member: if the individual has learned to choose to B1 given A1 and C1 given B1, and similarly for class 2, the individual also choose C1 given A1 and C2 give A2

Functional behavior

the lawful manner in which the rate and form of the behavior relate to the consequences that influence it in the past

Asymptote

the point at which the behavior reaches its peak; when the increase stops and the rate levels off and remains steady, possibly before declining

moment of transfer

the point to which each individual anticipates (responds before the prompt)

Response rates with FI schedules

the reinforced response tends to occur at low rates early in the interval and to increase gradually as the end approaches (this pattern is called a Scallop, based on the appearance of the FI performance in cumulative reports). it thus may not be a good choice when the target is maintain relatively consistent rates of responding over time

Automatic reinforcer

the reinforcement is inherent in the response

response cost (Src)

the removal or withdrawal of some quantities of reinforcers contingent on a response (the procedure must function to reduce the rate of the response on which it is contingent).

Alternating Treatment designs

the same person is the recipient of two or more rapidly alternating conditions often used as a tool for functionally analyzing the conditions associated with self injurious and destructive behavior

Simultaneous matching to sample

the sample item often a picture though sometimes a three dimensional object is presented while the other choices remain exposed

Progressive Differential Reinforcement of diminishing rates:

the size of the interval between responses is to lengthen, or the maximum number of targeted responses within the interval is to decrease gradually.

Progressive Ratio (PR) schedule

the size of the response requirement increase in some systemic way as in augmenting the requisite number of responses (on average) for reinforcers to be delivered At some point the requirement becomes so large that responding ceases for a while.

habituate

the weakening of an unlearned environmental-behavior relation when the environmental event is repeatedly presented without consequence (i.e. when the dear is no longer afraid of us) relation between the eliciting stimulus and the respondent reaction weakens

Delayed prompting

this technique shifts control of responding from the currently functional prompts (SDs) to the discriminate stimulus designated to evoke the behavior (S+). interposing gradually increasing periods of time between the discriminative stimulus and the artificial prompt.

Discriminated operants

those classes of behavior which the Sd sets the occasion for a response (seagull landing there) becase that response has different consequences (people bringing food) in the presence of that stimulus than it is absence promote tightly controlled performance

Pacing schedules

those setting upper and lower limits on reinforceable response rates. DRP is characterized by reinforcement arranged to occur contingent only on response rates within those limits. They are suitable in any instances in which a particular tempo is important as in performing certain assembly tasks. inappropriate for students with high impulsivity

Coping models

those who now have the skill to be demonstrated by are known to have experience difficulty with the behavior to be imitated in the past

variable interval schedule

time dictates when subject will be reinforced regardless of behavior; produces a steady rate of response and is hard to extinct

Interresponse Time (IRT)

time elapsed from R1 to R2

NCR allows you to ...

to break the contingent relation between the response and the reinforcer without depriving the individual of important reinforcers.

Stimulis Equalization

to eliminate differences in the irrelevant dimensions of stimuli. They temporarily reduced the complexity of stimulus by eliminating the irrelevant dimensions. Only the critical dimensions were left

Multi Element Designs, alternating treatment design, simultaneous treatment, mutiple schedules or concurrent schedules

treatments consisting rapidly alternated within or across sessions or days and that permit us to examine any emerging differences in the rates as a function of each intervention

How to identify social skill deficits.

use observation and rating scales to identify deficits -observation: watch person in action and compare to others in the setting -rating scales: use to help identify subtle social deficits

identify behavior function

use reinforcers from FBA test is conducted antecedent to prompt behavior MO to influence reinforcer anayse data

3 Common concern about reinforcement

using contrived over natural reinforcers bribery treating people differently than peers

most to least

usually takes the most trials to reach mastery, but results in the fewest number of errors.

Abolishing Operation

value-altering effect: A motivating operation that decreases the reinforcing effectiveness of a stimulus, object, or event. ex: food ingestion= decrease in the reinforcer effectiveness of food Behavior-altering effect: a decrease in current frequency of all behaviors that have been reinforced by that stimulus ex: food ingestion- a decrease in all behaviors that have been reinforced by food

behavioral contrast

when a procedure that decreases behavior is introduced into one context, the behavior maintained in other contexts may increase, despite no other change in contingencies directly affecting the latter. change in rate of responding opposite to the rate occurring within the treatment setting.

Discriminative control

when an individual responds consistently in the presence of a particular antecedent stimulus

S-delta

when it signals that the response is not likely to produce a reinforcer(reponse will go under extinction)

prediction

when repeated observations reveal 2 events that covary with each other

Equivalence classes

when stimuli assume equivalent functions they can be grouped in these classes

Weak or incomplete stimulus control

when the behavior occurs inconsistently in the presence of the relevant stimuli

tact versus intraverbal

while a tact allows you to talk about an object or event that is actually at hand and intraverbal allows a speaker to talk about objects and events that are absent

symmetry

will be able to reverse the direction of matching (choose B1 given A1 and B2 given A2, the individual also choose A1 given B1 and Given A2 given B2

Why is timeout considered more aversive than extinction?

with timeout, access to the full range of ordinarily available reinforcers is denied for a period of time.

Control condition

withhold antecedent stimuli or conditions and reinforcers to eliminate alternative explanations

Advantage of stimulus change

you can influence the frequency of those behaviors simply by presenting or withdrawing the controlling Sd

Whenever you have a punishment contingency...

you must also have a reinforcement contingency

Simple Stimulus Control

you present discriminative stimulus (SD) to evoke or reduce particular behavior

Differential Rf of High Rates (DRH)

you want the behavior to occur faster, so you reinforce the first behavior and then restart the interval. any behaviors outside the interval aren't reinforced

Differential Rf of Low Rates (DRL)

you want to slow down the response rate, so you do not reinforce behaviors in the interval and instead restart the interval if behaviors occur

Steps to increase delay gratification

•Make the reinforcer visible •Gradually increase the delay, or gradually increase the time engaged in the task •Provide learned or conditioned reinforcers during the delay •Teach clients to engage in providing themselves with self-instruction or self-prompt.
