Document Summary

Phobias- irrational fears of specific objects or situations. Classical conditioning- type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus. Studies saliva in dogs and noticed that dogs accustomed to the procedure would start salivating before the meat powder was pr esented. Decided to pair the presentation of the meat powder with various stimuli such as an auditory stimuli of a tone. The dog eventually began salivating at the tone. Tone had started out as a neutral stimulus that turned into the conditioned stimulus. Unconditioned stimulus (us)- stimulus that evokes an unconditioned response without previous conditioning. Unconditioned response (ur)- is an unlearned reaction to an unconditioned stimulus that occurs without previous conditioning. Conditioned stimulus (cs)- previously neutral stimulus that has, through conditioning, acquired the capacity to evoke a conditioned response. Conditioned response (cr)- learned reaction to a conditioned stimulus that occurs because of previous conditioning.
