Document Summary
4 classical conditioning mechanisms: contingency theory of conditioning, excitatory conditioning, the cs predicts the us, cs+ Inhibitory: predicts the absence of the us, decreases cr, cs- Information and conditional probability: experimental evidence is consistent with informational theory, yet, informational theory is incomplete without considering role of time in conditioning, cs-us interval (isi) Informativeness, redundancy, and blocking: selective associations, two prime examples, overshadowing. If a cs is a compound of two stimuli and one is more salient or noticeable than the other, then nearly all of the conditioning occurs to the more salient stimulus: Cs2 will be weak: blocking: the blocking effect, experimental group: reveals no cr to csb, control group that only gets training with the compound cs develops a cr to both csa and. Csb: the (cid:395)uestio(cid:374) is: (cid:449)h(cid:455) does(cid:374)"t the e(cid:454)pe(cid:396)i(cid:373)e(cid:374)tal group learn about csb, according to the original law of contiguity both.
