Contrast Perception Across Human Cognitive Style

Abstract

In the paper we tested hypothesis that subjects’ preferences to images with different contrast level is not only a function of image content but also of an individual pattern of perceptual organisation, which in terms of cognitive psychology is called a cognitive style. As reference to subjects’ perceptual preferences we used FRIS ® [15] that is a psychometric model and also an inventory for cognitive styles measurement. To test the hypothesis, the perceptual experiments were performed on a database included different content images. The received results confirm the given hypothesis, especially the obtained statistically significant results between idea-based thinking group and the rest of the thinking groups given for low contrast level.
