Document Summary
Class 23: common training design, presented unpaired. All the participants receive a procedure in which stimulus a is paired with the us and stimulus b is. Following that, responding to the us is evaluated following presentations of stimuli a and b. Once the cs became conditioned, presentation of the cs reduced how vigorously the participants blinked when they received the air puff (check study on p. 100). Conditioned: diminution of the ur, conditioned analgesia. Conditioned diminution of the ur is a prominent phenomenon in aversive conditioning and in conditioning: experiments where pharmacological agents serve as unconditioned stimulus. In both cases, a conditioned stimulus elicits physiological processes that serve to counteract the effects of the us. An aversive stimulus activates the defensive behavior system. Defensive responses like feeling or striking back at: a predator can be effective in coping with an attack. However, to engage in active defensive responses, the: organism cannot be debilitated by pain.
