Document Summary

Phobias: irrational fears of specific objects or situations: usually the result of classical conditioning. Learning: refers to a relatively durable change in behaviour or knowledge that is due to experience. Conditioning: involves learning associations between events that occur in an organisms environment. While investigating the role of saliva in the digestive process in dogs, he stumbled upon. Eventually the dogs would start salivating to the tone alone. The tone started out as a neutral stimulus; it did not originally produce the response of salivation, however he managed to change that by pairing it with a stimulus (meat) that did produce the salivation response. Unconditioned stimulus: (ucs) is a stimulus that evokes an unconditioned response without previous conditioning: meat powder. Unconditioned response: (ucr) an unlearned reaction to an unconditioned stimulus that occurs without previous conditioning: causing the dog to salivate. Conditioned stimulus: (cs) a previously neutral stimulus that has, through conditioning, acquired the capacity to evoke a conditioned response: the tone.
