Document Summary
Learning: process by which experience produces an enduring change in behaviour (or capabilities) Explained learning only in observable events (nothing mental) Based on internal responses to naturally occurring stimuli. But a stimulus gets the capacity to evoke a response that was originally evoked by another stimulus. Ucr: reflexive response elicited by ucs w/o prior learning. Cs: stimulus that, through association w/ ucs, comes to elicit a cr similar to the original ucr. Forward short delay: cs (tone) still present when ucs (food) presented. Forward trace: cs (tone) appears, then goes off, then ucs (food) presented. Process in which cs is presented in absence of ucs. The reappearance of an extinguished response after a period of non-exposure to the cs. Best if delay is less than 2-3 seconds. New crs are built on already established crs. Stimuli similar to initial cs elicits a cr. Cr occurs for one stimulus, but not another. The less similar, the easier it is to discriminate.
