PS102 Chapter Notes -Classical Conditioning, Drug Tolerance, Immunosuppression
Document Summary
Superstitions are often the result of obtaining a reward after engaging in some behaviour: operant conditioning : type of learning. Phobias: are irrational fears of specific objects or situations often result of another learning process: classical conditioning: can be treated but sometimes come to an abrupt but unplanned end on their own. Conditioning: involves learning connection between events that occur in an organism"s environment. Classical conditioning: a type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus. Conditioning must be evolutionarily adaptive, contributing to our reproductive fitness. Unconditioned stimulus (ucs): is a stimulus that evokes an unconditioned response without previous conditioning. Unconditioned response (ucr) is an unlearned reaction to an unconditioned stimulus that occurs without previous conditioning. Conditioned stimulus (cs): is a previously neutral stimulus that has, through conditioning, acquired the capacity to evoke a conditioned response.
