Multidimensional representational spaces: Face-space and Mind-space. In this example of Face-space (A), faces are represented on three orthogonal dimensions of brow ridge height, jaw width, and mouth width. In this Mind-space example (B), minds are represented on orthogonal dimensions which allow them to be individuated from one another. Dimensions may reflect cognitive abilities (e.g., intelligence), behavioral tendencies (e.g., recklessness), or personality traits (e.g., suspiciousness).
