6.1 Conditioning – learning associations between events that occur in an organisms environment Classical conditioning- a type of learning in shich a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus (pavlovian conditioning) Pavolv’s demonstration of classical conditioning included a dog being fed after the presence of a bell ringing. The key elements in this experiment included an unconditioned stimulus ( is a stimulus that envokes an unconditioned response with out previous conditioning.) an unconditioned response (an unlearned reaction to an unconditioned stimulus that occurs without previous conditioning) a conditioned stimulus (a previously neutral stimulus that has. Through conditioning, acquired the capacity to evoke a conditioned response) the last is the conditioned response (it is a learned reaction to a conditioned stimulus that occurs because of previous conditioning. Classical conditioning consists of any presentation of a stimulus or pair of stimuli Learning- any relatively durable change in behavior or knowledge that is due to experience o Shapes personal habits, personality triats, personal preferences and emotional responces o Everything learns o Principles that explain learned responses in animals explain much of human learning too 6.2 Classical conditioning often plays a key role in shaping emotional responses such as fears or phobias. Case studies of patients suffering from phobias suggest that many irrational fears can be traced back to experiences that involve classical conditioning. (certain childhood experiences may be the source of a certain phobia. Phobias- irrational fears of specific objects or situations Conditioned reflex (psych reflex)- classically conditioned responses that have traditionally been characterized as reflexes and said to be elicited because most of them are automatic or involuntary. 6.3 Acquisition refers to the initial stage of learning something.

Extinction is the gradual weakening and disappearance of a conditioned response tendency. The consistent presentation of the conditioned stimulus alone, without the unconditioned stimulus leads to extinction in classical conditioning. Spontaneous recovery is the reappearance of an extinguished response after a period of nonexposure to the conditioned stimulus Renewal effect takes place if a response is extinguished in a different environment than it was acquired, the extinguished response will reappear if the animal is returned to the original environment where acquisition took place. o
