三名辞系列問題の解決における方略

要旨

The purpose of this study is to clarify the mental process of integrating two premises in solving three-term series problem. The comparative pair used in this experiment was “larger-smaller”. The premises were presented in three ways: linguistic mode-for example “A is larger than B”, signal mode- “A>B”, and physical mode, in which the size of presented stimulus differed one another. The task was to decide whether three terms were ordered in one way or not. Six alternative models of the processes were tested by each subject: a grammatical linguistic model (GRL), a propositional linguistic model (PRL), a directional linguistic model (DIL), a grammatical linguistic-image mixed model (GRI), a propositional linguistic-image mixed model (PRI) and a directional image model (DII). Parameters of these models were figured out on the base of the different mental representations used in solving. The results said that six strategies were practically used by subjects and that each subject sometimes changed his strategy when the mode was changed.
