Document Summary

Relatively durable change in behaviour that is due to experience. Simplest form of learning involves learning associations between stimuli and responses. Type of learning in which a neutral stimulus acquires the ability to evoke a response that was originally evoked by another stimulus. Before conditioning: meat powder (unconditioned stimulus) causes the dog to salivate(unconditioned response). Ringing a bell (neutral stimulus) has no effect. During conditioning (acquisition): bell (conditioned stimulus) is associated with. Test for conditioning: bell(conditioned stimulus) causes dog to salivate (conditioned response) Cs starts just before ucs starts and they end together. Temporal association between the cs and the ucs. Ucs is presented and removed before presentation of cs(ns) Gradual weakening and disappearance of a conditioned response tendency. Reappearance of an extinguished response after a period of non-exposure to a cs. Organism responds to a new stimuli that are similar to the original cs. Ns (yellow light) -> us (air puff) -> ur (eye blink)
