Document Summary
Chapter 4 - classical conditioning: basic phenomena and various complexities. Acquisition refers to the process of developing and strengthening a conditioned response through repeated pairings of a neutral stimulus (ns) with an unconditioned stimulus (us) Acquisition proceeds rapidly during early conditioning trials and then gradually levels off. More intense uss produce stronger and more rapid conditioning than do less intense uss (more. The maximum amount of conditioning that can take place is the asymptote of conditioning for juicier and larger quantities of food than a dry little piece of food) More intense nss result in stronger and more rapid conditioning than do less intense nss (e. g. a loud metronome with food will have a stronger salivation response than a faint metronome) Extinction a conditioned response is weakened or eliminated when the conditioned stimulus cs is repeatedly presented in the absence of the us. Also applies to the procedure of repeatedly presenting the cs in the absence of the us.
