 Asch termed the highly influential traits which have a strong effect on overall impression as central traits, and the less influential traits which produced smaller effects on overall impression he called peripheral traits.According to Asch, the defining feature of a central trait is that it plays a significant role in determining the content and function of other traits.In the very first study he performed, Asch found that participants asked to form an impression of a person who was "intelligent, skillful, industrious, "warm", determined, practical, and cautious" formed significantly different impressions than participants asked to describe a person who was "intelligent, skillful, industrious, "cold", determined, practical, and cautious".
