THE AIM of this article is to present an experimental-theoretical formulation concerning some types of thinking processes. More specifically, I shall refer to the analysis of the cognitive aspects of problem-solving performances.
I shall first present some considerations pertaining to the evaluation of cognitive behavior in general. The usual approach consists of presenting a subject with problems, test items, or some other type of stimuli. By studying the responses given, the experimenter makes inferences concerning the psychological process of the subject. This kind of procedure has led to a concern that primarily centers around the study of the properties of the responses.
The study of the vicarious procedures that may be used in order to reach a response is seldom considered per se, and the inferences that are made concerning the process that mediates between the stimulus and the response can be risky
