Document Summary
Dogs would salivate even before their food was delivered into their mouth. Sound of metronome following training triggered salivation of dogs. Studying a contingent relationship: the presentation of one stimulus reliably leads to the presentation of another. Association between a signal and an event means a contingency has been formed between two stimuli. Classical conditioning: the learning of a contingency between a particular signal and a later event that are paired in time and/or space. Unconditioned stimulus: any stimulus or event (occurs naturally, prior to learning). Unconditioned response: the response that occurs after the unconditioned stimulus (occurs naturally, prior to any learning). Conditioned stimulus: paired with the unconditioned stimulus to produce a learned contingency. Previously neutral stimulus that after becoming associated with a us, eventually comes to trigger a response on its own. May take several trials of training in which the cs and us are paired before the cs alone elicits a response.
