意味論的記憶における文脈効果の実験的検討

意味論的文脈の特性

The effects of semantic context in the lexical decision task were examined by manipulating the association and frequency factors (Exp. I) and the presentation factor (Exp. II). After the lexical decision task, the recognition test of processing order (Exp. I) and the standard recognition test (Exp. II) were performed. The contextual effect based on association occurred in both experiments, especially in low-frequency words. But there were hardly any differences between forward and backward associations. The repetition effect was larger when a pair was presented again in the same arrangement than in the reverse. The following conclusions were drawn: (a) Semantic context works markedly upon the recognition of low-frequency words, and is effective in both the forward and backward directions of association. (b) Stimulus words are automatically restored with the processing-order informations after lexical decision.
