A Possible Basis for Individual Differences in Magnitude‐estimation Behaviour

A correlation was found between the amount of kinaesthetic figural after‐effect experienced by individual subjects (which may be related to the sensitivity of the central nervous sytem) and the slopes of their brightness‐estimation functions. These and related data suggest that part of the inter‐subject difference that is found in psychophysical magnitude‐estimation experiments is not random, but is due to differences in the way in which an individual's nervous system processes sensory information. Because the responses in magnitude‐estimation and kinaesthetic after‐effect tasks are different, it is unlikely that individual differences reflect response biases
