CORE DEFINITION

Information presented first in a sequence is more likely to be remembered—the psychological basis of "first impressions."

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Emphasize the opening. In speeches, writing, and meetings, the opening has a disproportionate impact on overall impression.

anchor

Anchor fast decisions

The primacy effect refers to the phenomenon where, when forming impressions of others or things, the information received first carries the most weight and is the most enduring. Stimuli presented earlier in a sequence are more easily encoded into long-term memory and dominate overall judgment.

MINIMUM ACTION

In progress 0/3

Practice this model in one real situation:

In interviews, speeches, and presentations, carefully design the first impression and key information at the beginning
place the most important points at the front of the sequence
pay attention to opening expressions and demeanor, as they anchor subsequent interpretation.
