Document Summary

Asymptotes highest strength that a response can be observed. Rate of acquisition tends to leap once they catch on. Extinction something will have already been conditioned, and then drops off. Spontaneous recovery when a response occurs again after the stimulus is brought back, after the response becoming extinct. Chapter 5: underlying processes, acquisition of phobias, treatment of phobias. The cs acts as a substitute for the us. E. g. , pizza a(cid:272)ti(cid:448)ates (cid:858)food (cid:272)e(cid:374)ter(cid:859) a(cid:272)ti(cid:448)ates (cid:858)sali(cid:448)atio(cid:374) (cid:272)e(cid:374)ter(cid:859) salivation: the doorbell for the pizza delivery could activate salivation too, e. g. , door bell a(cid:272)ti(cid:448)ates (cid:858)door(cid:271)ell (cid:272)e(cid:374)ter(cid:859) a(cid:272)ti(cid:448)ates (cid:858)sali(cid:448)atio(cid:374) center salivation. Consider: sign-tracking, evidence of neurological rewiring, e. g. , a light bulb signaling the presence of food. Consider: (cid:862)(cid:449)hite rats (cid:272)a(cid:374)(cid:859)t ju(cid:373)p(cid:863) effe(cid:272)t, contradicts basic s-s assumption. If it gets shocked when a light goes on, their response to the light should be the same as the response to the stimulus. But, what actually happens, is the rat freezes.
