Document Summary
Learning is a process by which experience produces a relatively enduring change in an organism"s behaviour or capabilities. Learning is measured by changes in an organism"s responses and is a form of personal adaptation to the environment: habituation is a decrease in the strength of a response to a repeated stimulus. It allows organisms to attend to other stimuli that are important. Classical conditioning: associating one stimulus with another: classical conditioning involves pairing a neutral stimulus with an unconditioned stimulus (ucs) that elicits an unconditioned response (ucr). Through pairing, the neutral stimulus becomes a conditioned stimulus (cs) that evokes a conditioned response (cr) similar to the original ucr: acquisition involves cs-ucs pairings. Extinction represents the disappearance of the cr when the cs is presented repeatedly without the ucs. Stimulus generalisation occurs when a cr is elicited by a stimulus similar to the original cs.
