HYPOTHESIS BEHAVIOR IN SELECTION PARADIGM
Keisuke Furuhashi · The Japanese journal of psychology · 1977
According to Hypothesis theory in concept identification problem, it is generally assumed that the subject samples only one hypothesis at a time and responds on the basis of the selected hypothesis. To evaluate this single-hypothesis assumption, a method was devised to examine whether the subject used the hypothesis or not, and if so, to detect the size of the hypothesis set held by the subject on each trial individually in a selection paradigm. The major findings were as follows: First, from the response selection tendency, the single-hypothesis assumption was rejected; there were large individual differences in how one selected the response. Second, there was no difference between the effects of positive and negative feedback. Finally, it was suggested that several factors may influence the hypothesis-checking behavior.
