title: Relationship between chromatic induction and spatial variables: an integrated explanation in terms of element-contribution function.
abstract: Chromatic induction as a function of separation and as a function of area was determined by a hue-cancellation procedure. Both functions obtained were expressed by exponential functions with similar exponential coefficients. This led to the derivation of an element-contribution function, based on a linear summation model, that could explain both the relationship between chromatic induction and separation and that between chromatic induction and area. The effects of separation and area on chromatic induction could readily be determined in terms of an element-contribution function. In addition, the induction area that is due to a blue inducing stimulus was larger than those that are due to the other inducing stimuli, suggesting that the summation area of the blue response was larger than those of the other chromatic responses.
