Auditory perception engages four distinct computational processes operating in parallel or serial

Evidence

Auditory perception is associated with a number of computational processes, which may act in parallel or serial, including: perceptual grouping, decision-making, attention, and categorization. (1) Perceptual grouping is a form of feature-based stimulus segmentation that determines whether acoustic events will be grouped into a single sound or be segregated into distinct sounds (Bregman 1990 ). (2) Auditory decision-making is a computational process in which the brain interprets sensory information in order to detect, discriminate, or identify the source or content of auditory stimuli (Gold and Shadlen 2007 ). Did I hear the stimulus? From where and whom did it come? What does it tell me? How can I use this information to plan an action? — Dijk, Pim van, Physiology, Psychoacoustics and…, 4881
