 Furthermore, when these participants were asked to rate which traits on the list were the most important to the formation of their impression, most reported that "warm" (or "cold") was one of the most influential traits on the list.Asch then performed the same experiment using "polite" and "blunt" in place of "warm" and "cold" and found that a change in these two traits had a much weaker effect on the overall impression than changing from "warm" to "cold".Additionally, when a negative central trait such as "cold" is inserted in a list of positive peripheral traits, it has a greater overall effect on the impression than a positive central trait such as "warm" does when it is inserted into a list of negative peripheral traits.
