Investigating Crossmodal Correspondences Between Vibrotactile Stimuli and Colors

Recent advances in the field of human cognition development have led to increased interest in the study of crossmodal correspondences, which explore compatibility effects between different sensory modalities. While various crossmodal correspondence domains have received extensive attention, there remains a knowledge gap concerning the compatibility between visual and tactile sensory stimuli. This research aims to extend our understanding of how visual and tactile stimuli interrelate and influence each other. In our conducted experiment, participants were tasked with matching specific colors to vibrotactile stimuli and vice versa. Results reveal a robust correlation between high-frequency vibrotactile stimuli 30.00-43.10 Hz and high saturation values 0.6-0.72 within a hue range of 345-30 degrees. Conversely, weak-frequency vibrotactile stimuli 0.00-15.00 Hz exhibited a correlation with low saturation values 0.15-0.36 within a hue range of 100-226 degrees. These findings suggest that crossmodal correspondences are triggered by both tactile and visual stimuli.
