Abstract

This research sought a better understanding of perceptual constancy in dynamic touch. It is argued that both traditional and ecological approaches are inadequate and that some qualitative experimental phenomenology analyses should be applied in addition to quantitative psychophysics methods. In an experiment, participants were asked to report the perceived length of rods by dynamic touch. Thereafter, self-reported changes in their impressions owing to different ways of wielding the rods were qualitatively analyzed. Qualitative analyses clarified differences in length perception that have not been investigated by quantitative approaches. To explore constancy in dynamic touch, it is preferable to integrate qualitative and quantitative approaches without eliminating the effects of different ways of wielding the material.
