Chapter 10- Learning Flashcards
Nonassociative learning
Occurs when an organism is repeatedly exposed to one type of stimulus; types: habituation & sensitization
Habit
An action that is performed repeatedly until it becomes automatic, and habituation follows a very similar process; “tune out” stimulus
Dishabituation
Occurs when the previously habituated stimulus is removed; if the stimulus were presented again, the person will react to it as if it were a new stimulus and is likely to respond even more strongly to it than before
Sensitization
When there is an increase in responsiveness due to either a repeated application of s stimulus or a particularly aversive or noxious stimulus; stimulus produces a more exaggerated response
Classical conditioning
Described by Ivan Pavlov and is sometimes called Pavlovian conditioning; occurs when a neutral stimulus, paired with a previously meaningful stimulus, eventually takes on some meaning itself; John Watson demonstrated with Little Albert
Conditioned stimulus (CS)
The initially neutral stimuli
Unconditioned stimulus (US)
The initially meaningful stimulus
Unconditioned response (UR)
The naturally occurring response; the response to the US does not have to be learned
Conditioned response (CR)
The response to the CS after conditioning
Forward conditioning
In which the CS is presented before the US, can be further divided into delay conditioning
Delay conditioning
In which the CS is present until the US begins
Trace conditioning
In which the CS is removed some time before the US is presented
Generalization
Grouping things together that look alike
Discrimination
Distinguishing among similar but distinct stimuli
Acquisition
Takes place when the paring of the natural and neutral stimuli have occurred with enough frequency that the neutral stimulus alone will elicit the conditional response
Extinction
The elimination of the conditioned response; can be achieved by presenting the CS without the US repeatedly
Spontaneous recovery
Where the original response disappears on its own, but then is elicited again by the previous CS at a later time; occurs when the CR reappears quickly but less strongly after the subject has been re-exposed to the pairing of the original neutral stimulus and US; demonstrates that even though the learning is not evident during the extinction period, the association between the CS and CR is still stored in the brain
Second-order conditioning
A previous CS now is used as the US; a special case of higher order conditioning, which, in theory, can go up to any order as new CSs are linked to old ones
Contiguity approach
Pavlov and Watson believed that the pairing of the neutral and natural stimuli occurred because they are paired in time
Contingency approach
Robert Rescorla believes that the CS and US get paired because the CS comes to predict the US; demonstrated through blocking, in which a natural stimulus was paired with two neutral stimuli
