Classical Conditioning Flashcards
temporal relation between CS and US
delay conditioning- CS precedes and overlaps US (optimal .5 seconds) (most efficient)
trace cond-CS presened and terminated before US (weaker than delay cond)
simultaneous cond-CS and US same time (wekare than two previous)
backword cond- US before CS, does not usually produce cond response
experimental neurosis
a pathological condition induced in a nonhuman animal during conditioning experiments requiring discriminations between nearly indistinguishable stimuli or involving punishment for necessary activities (e.g., eating). Experimental neurosis may be characterized by a range of behavioral abnormalities, including agitation, irritability, aggression, regressive behavior, escape and avoidance, and disturbances in physiological activity such as pulse, heart, and respiration rates. For example, in one experiment a dog learned to salivate in the presence of a circle, which had been paired with food, but not in the presence of an ellipse, which had not been paired with food. Faced with a difficult discrimination, the dog became agitated, barked violently, and attacked the apparatus, and all simple discriminations that had been learned were lost.
Overshadowing
Overshadowing is when two neutral stimuli that together create a CR but seperately only one produces the CR
blocking
redundance- Blocking involves two conditioned stimuli, CSA and CSB. Either one is capable of being conditioned to produce the CR. However, if training begins with a phase in which only CSA is paired with the US, and is then followed by a phase in which both CSA and CSB are paired with the US, then CSB fails to produce the CR. The prior conditioning involving CSA blocks the conditioning of CSB, even though in the second phase of training CSB is contiguous with the UR.
counderconditioning interventions
Wolpe:
reciprocal inhibition at the root
systematic desensitization (relation training, fear/anx hierarchy, imaginal exposure, in vivo)
sensate focus
Aversivr counterconditioning
in vivo AT (overt sensitization)- target bx is paired with aversive stim
covert senstiation- imagining aversive stim
