Individual Consistencies in Adaptation to Negative Afterimages and Spiral Aftereffects

Abstract

The study compares results from two experiments performed with 38 Ss, one experiment on the duration of spiral aftereffects (SAE), the other on the size, brightness and color of projected negative afterimages (AI). In both experiments stimulus presentations were repeated until the series of data thus obtained were reasonably stabilized at a “final level.” SAE correlated with AI as regards both this final level and the progression of change preceding it if in the latter experiment size and brightness data were combined. AI color was also related to SAE duration.
