Document Summary
Learning (traditional learning) require new skill new action. Process by which experience produces a relatively enduring change in behaviour or capabilities (knowing how ) Examined processes by which experience in uences behaviour. Discovered laws of learning that apply to virtually all organisms. Explained learning solely in terms of directly observable events. Based on internal responses to naturally occurring stimuli (lemon - we have natural reaction just thinking about it) Come things we encounter in the world naturally elicit a response in us. When we pair things that don"t have a value, or have a different value with these naturally occurring pairings, Ucs (us) = unconditioned stimulus - stimulus that elicits a re exive or innate, unconditioned response (ucr) without prior learning. Stimulus that, through association with the ucs, comes to elicit a conditioned response similar to the original ucr. Is a natural response - no learning involved. Noted dogs salivated at sounds (e g) footsteps; tone)
