Classical Conditioning- Chapter
4
Basic Conditioning Phenomena
-Acquisition is the process of developing and strengthening a conditioned response through
repeated pairings of a neutral stimulus with an unconditioned stimulus
-Asymptote- maximum amount of conditioning that can take place in a particular situation
-more intense unconditioned and neutral stimulus produce stronger and more rapid
conditioning
-extinction- a conditioned response is weakened when the conditioned stimulus is repeatedly
presented in the absence of the unconditioned stimulus
-a response that has been extinguished can be quickly reaquired when the unconditioned
stimulus is presented with the neutral stimulus
-Spontaneous Recovery- reappearance of a conditioned response to a conditioned stimulus
following a rest period after extinction
-Disinhibition- the sudden recovery of a response during an extinction procedure when a new
stimulus is introduced
-dishabituation involves the reappearance of a habituated response, and disinhibition involves
the recovery of a response that has been inhibited due to extinction
-Stimulus generalization- tendancy for a conditioned response to occur in the presence of a
stimulus that is similar to the conditioned stimulus
most apparent when the stimuli are physically similar
semantic generalization is when the stimuli have similar meanings
-Stimulus discrimination- tendancy for a response to be elicited by one stimulus more than
another
Two Extensions to Classical Conditioning
-Higher-Order Conditioning- a stimulus that is associated with a conditioned stimulus can
also become a conditioned stimulus
commonly used in advertising, pairing a company name with objects, events, or people to
elicit positive emotional responses
-sensory preconditioning- when one stimulus is conditioned as a conditioned stimulus,
another stimulus that was previously associated with it can also become a conditioned
stimulus
more effective when the two stimuli are presented simultaneously rather than sequencially
Specificity in Classical Conditioning
-compound stimulus- the simultaneous presentation of two or more individual stimuli
-Overshadowing
the most salient member of a compound stimulus is more readily conditioned as a CS and
thereby interferes with conditioning of the least salient member
only in the presence of the most salient stimulus does the least salient stimulus come to
elicit little or no response
-Blocking
the presence of an established CS interferes with the conditioning of a new CS
