Modifying auditory perception with prisms? Aftereffects of prism adaptation on a wide auditory spectrum in musicians and nonmusicians

Prism adaptation consists of pointing to visual targets while wearing prisms that shift the field laterally. The aftereffects are not restricted sensorimotor level but extend spatial cognition. There is a link between representation and auditory frequency, with an association low frequencies on left side high right space. present study aimed first at evaluating wide range in musicians nonmusicians. We used ‘auditory interval bisection judgment’ within three intervals. results showed pseudoneglect behavior pretest nonmusicians for frequency intervals, reflecting perceptual bias subjective center toward lower frequencies. second aim was evaluate prism expanded spectrum. leftward optical deviation intervals Adaptation affects perception extended spectrum, by shifting provides innovative data about its modulation adaptation.
