PLEASE HELP IM STRUGGLING AND ABOUT TO GO NUTS 53. For extinction to occur, which of the following
must be true of the conditioned response (CR), the
conditioned stimulus (CS), and the unconditioned
stimulus (UCS) ?
(A) The CR occurs after the CS but does not
occur after other stimuli.
(B) The CR occurs after a stimulus that is similar
to the CS.
(C) The CS and the UCS are repeatedly paired,
and the CR gains strength.
(D) The CS is repeatedly presented in the absence
of the UCS, and the CR loses strength.
(E) When the CR loses strength, a rest period
is given, after which the CS again elicits
the CR.
