Average correlations within and across conditions among subjects’ similarity matrices.

For example, the value in the Visual-Visual cell was calculated by averaging over correlations in subjects’ similarity ratings for each pair of subjects in the visual condition (because there were 7 subjects in this condition, there were 42 = 7 × 6 such pairs). Similarly, the value in the Visual-Haptic cell was calculated by averaging over correlations for each pair of subjects when one subject was in the visual condition and the other subject was in the haptic condition (because there were 7 subjects in each condition, there were 49 such pairs).Average correlations within and across conditions among subjects’ similarity matrices.
