Abstract

This study examined the relationship between a set size of stimuli and the context effects in impression formation. It was assumed that the context effects tend be larger when the set size of stimuls list decreases, In an attempt to test this assumption, an experiment was performed, manipulating the set size of the stimulus lists and inducing the context effects. The set size of lists was ranged one to four, while the favorableness of the stimulus lists were constant. The context effects were induced by the presentation order of the stimulus series. Subjects were presented with the stimulus lists and rated their liking for the adjective traits under different contexts. Consistent with our prediction, results showed significantly decreases in context effects as the set size of lists increased and the structure of stimulus were differentiated.
