Katz (1925) proposed that perception of texture depends on two cues.Spatial cues are determined by the size, shape, and distribution of surface elements.Temporal cues are determined by the rate of vibration as skin is moved across finely textured surfaces.Two receptors may be responsible for this process: the duplex theory of texture perception.Past research showed support for the role of spatial cues.Recent research by Hollins and Reisner shows support for the role of temporal cues.In order to detect differences between fine textures, participants needed to move their fingers across the surface.
