Document Summary
Chapter 5 thomas brown: the more frequently two stimuli are paired the more strongly will an individual associate the two. + and - represent presence and absence of the us group. Conditioning is not an automatic result when a cs and us are paired. Conditioning will occur only if it is informative, only if it is predictive of something important such as an upcoming shock. The subject is a selective learner, learning about informative stimuli and ignoring informative ones. Designed to predict the outcome of classical conditioning procedures on a trial by trial basis. For any trial in which one or more cs is presented, the model assumes that there can be either excitatory, inhibitory, or no conditioning. Two factors determine which of these three possibilities actually occurs: the strength of the subjects expectation of what will occur, the strength of the us that is actually presented.
