[An experiment in using Sternberg's paradigm in studying cognitive visual functions in man]
Abstract:
Sternberg's technique of additive factors was used. Subjects had to define whether the test and the standard stimuli were identical or not by pressing one of two buttons. Reaction time was shorter in the trials with identical stimuli than in the trials with different ones. Three factors were shown to underly the difference. First, the duration of comparison of visual images under the same and different conditions was not equal. Second, there were fewer comparisons in the trials with identical stimuli. Third, the duration of comparison of stimuli and the number of comparisons could affect other stages of perceptual task.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
