Abstract

External objects and their qualities are verbali zed in the process of the development from nonverbal congnition to verbal congnition. Pavlov defined the word as the signal of signal, and Vygotsky emphasized the necessity of the psychological researches of speech as the mediational link which determines human behavior. But we have yet no psychological research that has applied these views concretely. We will start with the problem: what is the psychological meaning of the “verbalization”?<BR>When we try to classify some objects into some categories, we must cognize not only the quality which each object has, but that which it has not. In this study, our task is to solve the problem how some non-attaching quality becomes cognized, and make the role of “verbalization” in this process clear.<BR>Working hypotheses:<BR>(1) That some object X has not a quality Q is congnized, only if “(X) has no Q” is verbalized anobjectified.<BR>(2) If the hypothesis (1) is right, quality Q can be cognized by the help of other's verbalization by subjects who are not able to verbalize it for themselves.<BR>(3) There may be some developmental transit: from the stage at which the verbalization does not function as objectification to the stage at which a subject can verbalize Q for himself.<BR>Procedure of experiment<BR>The subjects are 205 preschool children, 4-6 years old, and 68 students. The experimental material consists of 12 wooden blocks varying in color and shape, a half of which have a white stripe on their side and the rest have not. There are five difierent colors: red, dark blue, yellow, green and gray, and three different shapes: cylinder, regular trigonal prism and regular rectangular prism. Subjects had to classify the blocks into four categories.(cylinder and non-cylinder, striped and non-striped)
