The purpose of this study was to examine changes in confidence rating from a phenomenological approach. In experiment, participants (N=12) were required to perceive rod length by haptic touch without vision and to rate their confidence level in each trial. One group transformed their exploratory movement for length perception from dynamic touch to static holding, and another group did the same thing but in inverse order. Result showed that dynamic touch could perceive the actual extent accurately than static holding, and that the transition from dynamic touch to static holding made participants have less confidence on their perception, but the reverse transition had no effect. It was discussed that change in confidence would have context-dependent characteristics, considering the idea of coherence.
