Learning and Memory Flashcards
Habituation
Repeated exposure to the same stimulus can cause a decrease in response.
Dishabituation
~The recovery of a response to a stimulus after habituation has occurred.
~When a second stimuli intervenes, causing desensitization to the original stimulus.
~Causes an increase in the original stimulus.
Associative Learning
~Creation of a pairing, or association, either between two stimuli or between a behavior and a response
Classical Conditioning/ Acquisition
~Takes advantage of biological, instinctual responses to create associations between two unrelated stimuli.
~Unconditioned stimuli, unconditioned response, neutral stimuli, conditioned stimulus and conditioned response.
Unconditioned Stimulus
Any stimulus that brings a reflexive response.
Unconditioned Response
Innate or reflexive response.
Extinction
~If the conditioned stimulus is presented without the unconditioned stimulus enough times, the organism can become habituated to the conditioned stimulus.
~When the bell rings without the presence of food, the dog may stop salivating.
Spontaneous Recovery
If an extinct conditioned stimulus is presented again, a weak conditioned response can sometimes be exhibited.
Generalization
~A stimulus similar enough too the conditioned stimulus can also produce a conditioned response.
~Little Albert
Discrimination
An organism learns to distinguish between two similar stimulus.
Operant Conditioning
Links voluntary behaviors with consequences in an effort to alter the frequency of those behaviors.
Reinforcement
Process of increasing the likelihood that an individual will perform a behavior.
Positive Reinforcement
Increases behavior by adding a positive consequence or incentive.
Negative Reinforcement
They increase a behavior by removing something unpleasant.
Escape Learning
The role of behavior is to reduce the unpleasantness of something that already exists.
Avoidance Learning
Prevent the unpleasantness of something that has yet to happen
Primary Reinforcer
A treat that the organism responds to it naturally
Conditioned Reinforcer/ Secondary Reinforcer
Like a click in aquariums
Discriminative Reinforcer
The trainer that har the clicker.
Punishment
Reduces the presence of the behavior.
Positive Punishment
Adds an unpleasant consequenceina response to a behavior to reduce that behavior.
Negative Punishment
Reduction of behavior by removing stimulus.
Reinforcement Schedules
Fixed-Ratio, Variable-Ratio, Fixed-Interval and Variable-Interval
Fixed-Ratio
Reinforces behavior after specific amount of times.
Variable-Ratio
~Resistant to extinction.
~Reinforce a behavior after a varying number of performances of the behavior, but such that the average number of performances to receive a reward is relatively constant.
Fixed-Interval
Reinforces the first instance of a behavior after a specified time period has elapsed.
