Document Summary
Study questions: identify ucs, cs, ns, cr ucr (and the pairing methods used to establish a cs) when analyzing classical conditioning examples. Ucs stands for unconditional stimulus (also sometimes called unconditioned; either are ok); the ucs automatically (that is, without any previous learning) causes/elicits an involuntary response. Cs stands for conditional (or conditioned) stimulus; a previously neutral environmental event (a stimulus) that now causes/elicits an involuntary response because it has been repeatedly paired with a ucs. Any environmental event that doesn"t automatically cause/elicit an involuntary response. Cr or conitional (or conditioned) response is a learned involuntary response that is elicited by a cs. There are four methods that can be used to convert/transform a neutral stimulus (ns) into a conditioned stimulus (cs). In order of effectiveness (which means the first requires fewer pairing than the second which requires fewer than the third which requires fewer than the last) these pairing methods are trace, delay,
