Learning Flashcards
Associative Learning
Pairing between a behavior and response (Operant vs Classical)
Classical conditioning
Previously neutral stimulus becomes associated with an unconditioned stimulus to elicit conditioned response
Neutral Stimulus
Does not initially bring about response
Unconditioned stimulus
Naturally triggers a response without conditioning
Unconditioned response
Natural, unlearned response to unconditioned stimulus
Conditioned stimulus
Previously neutral stimulus, now associated with unconditioned stimulus, triggers conditioned response
Conditioned response
Learned response to previously neutral stimulus
Acquisition
Process of associating an unconditioned stimulus with conditioned stimulus
Extinction
Decrease / eventual disappearance of conditioned response due to absence of reinforcement
Habituation
Decrease response to repeated stimulus over time
Dishabituation
Recovery of habituated response after change in stimulation
Spontaneous recovery
Reappearance of conditioned response after period of lessened response without occurrence of new reinforcement
Stimulus generalization
Conditioned response is triggered by stimuli that are similar to the conditioned stimulus
Stimulus discrimination
Ability to differentiate vt similar stimuli when only one is consistently associated with unconditioned stimulus
Operant conditioning
Learning process where consequences of a behavior affect the probability of that behaviors occurrence
Positive reinforcement
Adding pleasant stimulus to encourage behavior
Positive punishment
Adding aversive stimulus to discourage behavior
Negative punishment
Removing a desired stimulus to discourage behavior
Negative reinforcement
Removing aversive stimulus to encourage behavior
Escape learning
Terminate an ongoing, unpleasant stimulus -> type of negative reinforcement; distance self once presented with undesirable stimulus
Avoidance learning
Type of negative reinforcement in which an attitude or behavior is learned that causes avoidance of something in the future
Different types of partial reinforcement
Fixed ratio: reward after set # of behaviors
Variable ratio: reward after unpredictable # of behaviors
Fixed interval: reward after set time period
Variable interval: reward after changing time intervals
Latent learning
Learning that is not immediately exhibited
Instinctive drift
Reverting to instinctual behaviors despite conditioning efforts
Observational Learning
Acquiring skills by observing others
Imitation
Direct replication of observed behavior
Mirror neurons
Activated when action is performed AND when that behavior is observed
