When asch (1946) presented students with a description of someone as "intelligent, industrious, impulsive, critical, stubborn, and envious," they rated the person more positively than if the opposite order of adjectives was presented. this demonstrates the effect?

I believe the answer is: Primacy effect
Primacy effect refers to the psychological effect when people perceive the information that we receive earliest as the basis of truth that influence our perception for the rest of the information.
This happen due to the limitation of people's ability  to maintain attention for a long period of time.

Idk for this one pal
