Learning Flashcards
Learning
A long-lasting change in behavior resulting from experience
No associative learning
When an organism is repeatedly exposed to one stimulus
Sensitization
Increase in responsiveness due to either a repeated application of a stimulus or a particular aversive or noxious stimulus
Desensitization
A decreased responsiveness to an aversive stimulus after repeated exposure
Classical conditioning
When a neutral stimulus, paired with a perviously meaningful stimulus, eventually takes on some meaning itself
Conditioned stimulus
The initially neutral stimulus
Unconditioned stimulus
The initially meaningful stimulus
Unconditioned response
An unlearned response to an unconditioned stimulus
Conditioned responses
The response to the conditioned stimulus after conditioning
Generalization
The tendency for a conditioned response to be evoked by stimuli that are similar to the stimulus to which the response was conditioned
Discrimination
The tendency for an organism to distinguish between a CS and a similar stimulus
Acquisition
When the pairing of the natural and neutral stimuli have occurred with enough frequency that they neural stimulus alone will elicit the conditioned response
Extinction
The elimination of the conditioned response
Spontaneous recovery
The recurrence of an extinguished response as a function of the passage of time
Operant conditions
An organism’s learning to make a response in order to obtain a reward of avoid punishment
Law of effect
Rewarded behaviors are more likely to be repeated
Primary reinforcement
Natural reinforcers (food, water, sex)
Secondary reinforcement
Learned reinforcers (learning that money has value)
Positive reinforcement
A reward or event that increases the likelihood that a particular response will be repeated
Negative reinforcement
The removal of an averíese event in order to encourage behavior
Omission training
Decrease the frequency of behavior by withholding the reward until the desired behavior is demonstrated
Schedule of reinforcement
The frequency with which an organism receives e reinforcement for a given response
Continuous reinforcement schedule
Every correct response that is emitted results in a reward
Partial reinforcement schedule
Schedule of reinforcement in which not all responses are reinforced
