People who are averse to uncertainty exhibit expanded semantic representations

Semantic representations enable humans to identify stimuli. We illustrate that the organization of semantic representations is in part shaped by psychological needs: people who are averse to uncertainty have more-differentiated and separable semantic representations than individuals who are tolerant of uncertainty, and this separation predicts improved discrimination but poorer generalization.
