Document Summary
Ww2: people responded to the whistling sound of wartime bombing. The variable cs came to produce a fear response. Stimulus generalization: one specific cs is paired up to produce a contingency. However, a similar cs might produce the same cr. (provides efficiency and flexibility) ex. you were bit by a black doberman. Every time you see a black doberman, a fear response is given. However, you may produce a fear response by seeing any type of dog. Stimulus discrimination: restricts the range of the cs"s that can elicit a cr (opposite of stimulus generalization; refines the learning process) Cs+: presence of stimulus / cs-: absence of a stimulus ex. lion and gazelle. gazelle must know if any lion are around (cs+), and if there aren"t any around (cs-) Phobia: an exaggerated, intense and persistent fear of certain situations, activities, things or people. Treating a phobia: present the cs repeatedly w/o the us.
