In 1946, Solomon Asch directed one of the earliest known empirical studies of human construal. In this study, Asch focused on the formation of character impressions by asking each participant to study a list of personality traits and make judgments and/or inferences about the possessor of each of these listed traits. The results of this study demonstrated two different types of phenomena: the primacy effect and the disproportionate effect of certain types of words. For the primacy effect, those personality traits that were listed earlier in the list seemed to have much more influence on the subject's impression of the person with that trait. However, Asch's finding that there was a variability in the effect of categorical terms such as "warmth" and "coldness" hint that those listed traits were "susceptible to variable interpretation or construal—and the specific meaning attached depended upon the more global impressions adopted by the subjects".
