Reinforcement Schedules (handout)
-Continuous reinforcement - 1/1 behavior / reinforcement. -Intermittent reinforcement - fixed / variable - ratio / interval
Cognitive Map
a mental representation of the layout of one's environment
Neutral Stimulus (NS)
a stimulus that does not initially elicit a response
Fixed Ratio Reinforcement Schedule
set number of responses must occur before a behavior is rewarded
Observational Learning
type of learning that occurs by watching others
__________ is when you take away a pleasant stimulus to stop a behavior.
D. Negative punishment
In Watson and Rayner's experiments, Little Albert was conditioned to ear a white rat, and then he began to be afraid of other furry white objects. This demonstrates ______.
D. Stimulus generalization
In _______ the stimulus or experience occurs before the behavior and then gets paired with the behavior.
D. classical conditioning
Operant Conditioning
form of learn in which the stimulus/experience happens after the behavior is demonstrated
Associative Learning
form of learning that involves connecting certain stimuli or events that occur together in the environment (classical and operant conditioning)
Primary Reinforcer
has innate reinforcing qualities (e.g., food, water, shelter, sex)
Reinforcement
implementation of a consequence in order to increase a behavior
Unconditioned Response
natural (unlearned) behavior to a given stimulus
Variable Ratio Reinforcement Schedule
number of responses differ before a behavior is rewarded
Vicarious Reinforcement
process where the observer sees the model rewarded, making the observer more likely to imitate the model's behavior
Continuous Reinforcement
rewarding a behavior every time it occurs
In Bandura's Bobo doll study, when the children who watched the aggressive model were placed in a room with the doll and other toys, they _______.
D. Kicked and threw the doll
Secondary Reinforcer
has no inherent value unto itself and only has reinforcing qualities when linked with something else (e.g., money, gold stars, poker chips)
Punishment
implementation of a consequence in order to decrease a behavior
Conditioned Response (CR)
response caused by the conditioned stimulus
Spontaneous Recovery
return of a previously extinguished conditioned response
Stimulus Discrimination (handout)
-when an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimulus.
Who proposed observational learning?
C. Albert Bandura
Fixed Interval Reinforcement Schedule
behavior is rewarded after a set amount of time
Variable Interval Reinforcement Schedule
behavior is rewarded after unpredictable amount of time have passed
Law of Effect
behavior that is followed by consequences satisfying to the organism will be repeated and behaviors that are followed by unpleasant consequences will be discouraged
Taste aversion (handout)
can have a longer time interval (ex. alcohol, food poison ing, pest control)
Extinction
decrease in the conditioned response when the unconditioned stimulus is no longer paired with the conditioned stimulus
Stimulus Generalization
demonstrating the conditioned response to stimuli that are similar to the conditioned stimulus
Classical Conditioning
learning in which the stimulus or experience occurs before the behavior and then gets paired or associated with the behavior
Acquisition
period of initial learning in classical conditioning in which a human or an animal begins to connect a neutral stimulus and an unconditioned stimulus so that the neutral stimulus will begin to elicit the conditioned response
Vicarious Punishment
process where the observer sees the model punished, making the observer less likely to imitate the model's behavior
Partial Reinforcement
rewarding behavior only some of the time
Shaping
rewarding successive approximations toward a target behavior
Conditioned Stimulus
stimulus that elicits a response due to its being paired with an unconditioned stimulus
Unconditioned Stimulus (UCS)
stimulus that elicits an automatic response
Negative Punishment
taking away a pleasant stimulus to decrease or stop a behavior
Negative Reinforcement
taking away an undesirable stimulus to increase a behavior
Habituation
when we learn not to respond to a stimulus that is presented repeatedly without change
Cognition and Latent Learning (handout)
-Edward Tolman -Learning that occurs but is not observable until there is a reason to demonstrate it. Ex. Children learn by watching the actions of parents.
Behaviorism (handout)
-John Watson - founder * P-sychology must focus on outward observable behavior that can be measured in order for psychology to become a legitimate science. -Must shift its concern away from internal mental processes because they can not measured. -Psychology must focus on outward behavior that can be measured. -Human behavior, just like like animal behavior, is primarily the result of conditioned responses. (Little Albert) -Advertising Lincoln continental - Matthew McConaughey Most interesting man in the world - Dos Equis Beer
Observational Learning/ Modeling (handout)
-Models - individuals performing the imitated behaviors -Bandura - internal mental states must have a role in learning -Models 1. live 2. verbal 3. symbolic -Steps in the modeling process 1. attention 2. retention 3. reproduction 4. motivation --vicarious reinforcement- vicarious punishment -Prosocial / antisocial effects? -violent movies, TV, video games ?
Classical Conditioning (handout)
-Pavlov - Research on digestion using dogs -Classical Conditioning - a process by which we learn to associate stimuli and, consequently, to anticipate events. -Unconditional Stimulus (UCR) - a stimulus that elicits a reflexive response in an organism. ex. meat powder. -Unconditional Response (UCR) - a natural (unlearned) reaction to a stimulus. -Neutral Stimulus (NS) - a stimulus that does not naturally elicit a response. Paired repeatedly NS - -UCS = Conditioned -Stimulus (CS) - a stimulus that elicits a response after repeatedly being paired with an unconditioned stimulus. -Conditioned Response (CR) - the behavior caused by the conditioned stimulus Conditioning. -Processes in Classical Conditioning -Acquisition - initial period of learning.
Reinforcement (handout)
-Positive Reinforcement - a stimulus that is added that increases the behavior.*not a desirable stimulus -Negative Reinforcement - a stimulus is removed to increase a behavior. -PUNISHMENT - A stimulus that decreases a behavior -Positive punishment - a stimulus added to decrease a behavior. -Negative punishment - removal of a stimulus to decrease a behavior. -Problems with punishment -Tends to suppress behavior not change it. -Can increase aggression / frustration -SHAPING - reward of successive approximations of target behaviors. -Primary Reinforcer - reinforcer that have innate reinforcing qualities (not learned)Ex. food, water, sex, touch, attention -Secondary Reinforcer - no inherent value and only has reinforcing qualities when linked with a primary reinforcer. -Ex. money, tokens, praise
Operant Conditioning (handout)
-Target behavior is followed by reinforcement or punishment to either strengthen or weaken it, so that the learner is more likely to exhibit the desired behavior in the future. -The stimulus (reinforcement or punishment) occurs soon after the response. -B. F. Skinner - classical conditioning is limited to existing behaviors that are reflexively elicited - behavior is motivated by the consequences we receive for the behavior. -Law of Effect (Edward Thorndike) -Skinner Box - pigeons / rats
What is learning (handout)
-Unlearned Behaviors -Instincts Reflexes - a motor or neural reaction to a specific stimulus in the environment. -Ex. babies suck, turtles head to the ocean -Learned Behaviors - involve change and experience -Learning - a relatively permanent change in behavior / knowledge that results in experience. -Associative learning - occurs when an organism makes connections between stimuli or events that occur together in the environment. -3 main types of learning 1. Classical Conditioning 2. Operant Conditioning 3. Observational Learning
Habituation (handout)
-occurs when we learn not to respond to a stimulus that is presented repeatedly without change.
Extinction (handout)
-the decrease in the conditioned response when the unconditioned stimulus is no longer presented with the conditioned stimulus.
Spontaneous Recovery (handout)
-the return of a previously extinguished conditioned response following a rest period.

Stimulus Discrimination
ability to respond differently to similar stimuli
Positive Reinforcement
adding a desirable stimulus to increase a behavior
Positive Punishment
