Duplex Theory Of Texture Perception

The Duplex Theory of Texture Perception refers to the idea that the perception of texture depends on two things. First, coarse textures are determined by spatial cues, or the size, shape, and distribution of elements along the surface. On the other hand, fine textures are determined by temporal cues, or the rate of vibration as you move your finger across the surface. Two different types of receptors are thought to be responsible for detecting spatial and temporal cues.
