psychology ch 6
operant conditioning
(Skinner) organisms learn to associate a behavior and its consequence
positive punishment
add an undesirable stimulus to decrease a behavior
punishment`
always decreases a behavior
associative learning
an organism makes connections between stimuli or events that occur together in the environment
negative reinforcement
an undesirable stimulus is removed to increase a behavior
conditioned response (cr)
behavior caused by the conditioned stimulus (dog salivation)- caused by the tone of the bell, not the meat powder
law and effect
behaviors that are followed by punishment are less likely to be repeated. behaviors that are followed by a reward are more likely to be repeated
reflexes and instincts
do not have to be learned
John B Watson
founder of behaviorism
secondary reinforcers
has no inherent value and only has reinforcing qualities when linked with a primary reinforcer(praise, money)
classical conditioning
learn to associate stimuli and, consequently, to anticipate events
latent learning
learning that occurs but is not observable in behavior until there is a reason to demonstrate it
reflexes
motor or neural reaction to a specific stimulus in the environment
partial reinforcement
not getting reinforced every time they perform a desired behavior
habituation
occurs when we learn not to respond to a stimulus that is presented repeatedly without change (the tv is annoying at first, but after time forget that its on)
classical and operant conditioning
only learned from experience
fixed interval
reinforcement is delivered at predictable time intervals (hospital patient uses patient-controlled, doctor timed pain relief. knows when)
variable interval
reinforcement is delivered at unpredictable time intervals (checking facebook. never knowing when, but being ready)
primary reinforcer
reinforcers that have innate reinforcing qualities(food, shelter, sex, pleasure)
learning
relatively permanent change in behavior or knowledge that results from experience
negative punishment
remove an undesirable stimulus to decrease a behavior
shaping
reward successive approximations of a target behavior
variable
the number of responses between reinforcements, or the amount of time between reinforcements, which varies or changes
fixed
the number of responses or amount of time between reinforcements, which is set and unchanging
spontaneous recovery
the return of a previously extinguished conditioned response following a rest period
ratio
the schedule is based on the number of responses between reinforcements
interval
the schedule is based on the time between reinforcements
positive reinforcement
a desirable stimulus is added to increase a behavior
cognitive map`
a mental picture of the layout of the maze
unconditioned response (ucr)
a natural (unlearned) reaction to a given stimulus (Dog's salivation)-caused by ucs
neutral stimulus (ns)
a stimulus that does not naturally make a response (tone'bell')-becomes the cs
unconditioned stimulus (ucs)
a stimulus that makes a reflexive response in an organism (meat powder)-makes dog drool-causes unconditioned response
conditioned stimulus (cs)
a stimulus that makes a response after repeatedly being paired with an unconditioned stimulus (the dog begins to salivate to the tone alone without the meat powder)-was an add on, became the reason it salivated
Ivan Pavlov
classical conditioning; an organism has two types of responses to its environment: 1)unlearned responses (reflexes) 2)learned responses (conditioned)
extinction
decrease in the conditioned response when the unconditioned stimulus is no longer presented with the conditioned stimulus
vicarious punishment
if the model is punished, you will be less motivated to copy him
vicarious reinforcement
if the model is reinforced on his behavior, you will be more motivated to copy him
models
individuals performing the imitated behavior
instincts
innate behaviors that are triggered by a broader range of events
second-order conditioning
using the conditioned stimulus to condition another stimulus (using the can opener, and then adding a squeak) the cat responds to both the can opener and the squeak now.
observational learning
we learn by watching others and then imitating or modeling what they do or say
stimulus generalization
when an organism demonstrates the conditioned response to stimuli that are similar to the conditioned stimuli (cannot tell the difference between the sound of the bell and the mixer)
aquisition
when an organism learns to connect a neutral stimulus and an unconditioned stimulus (eating food(ns), getting sick(ucs), hating food(answer))
stimulus discrimination
when an organism learns to respond differently to various stimuli that are similar (being able to identify the sound of a bell, other than the sound of a mixer)
continuous reinforcement
when an organism receives a reinforcer each time it displays a behavior (giving a dog a treat after doing good)
