Three different hypotheses have been proposed to account for individual differences in figural after‐effects (Klein & Krech, 1952; Wertheimer & Wertheimer, 1954; Eysenck, 1955). Each implies the existence of a positive correlation between the measures of after‐effect in different modalities. The study reported here explored this problem for vision and kinaesthesis. Thirty‐two subjects were used and no significant correlation was found (α = 0·05). Men showed significantly larger visual figural after‐effects than women, a finding analogous to Wertheimer's (1954a) in kinaesthesis. There was no significant rank correlation between either effect and extraversion‐introversion as measured by Heron's (1950) sociability index.
