Document Summary

Learning: a more-or-less permanent change in behaviour or that results from experience. Stimulus and response: classical conditioning: form of learning where animal learns association with two stimuli. In pavlov"s terms, unconditioned stimulus (ucs) produces unconditioned response (ucr). In his experiment, food is the ucs and salivating is the ucr. It requires many trials (often around 20) of the cs and. Ucs happening at about the same time before conditioning can be demonstrated. How the neutral stimulus (the eventual cs) and the ucs are presented is also crucial. Acquisition: most effective way to produce classically conditioned response is delay conditioning, where the onset of the cs precedes the onset of the ucs. As a result, the cs essentially predicts the occurrence of the ucs: other possible combinations for presenting the cs and the ucs include, changing order of events, so food is presented before bell rings (ucs before the. This is called backward conditioning; is least effective form of conditioning.
