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.
