Topic: pitch direction

To discern speech or appreciate music, the human auditory system detects how pitch increases or decreases over time. However, the algorithms used to detect changes in pitch, or pitch motion, are incompletely understood. Here, using psychophysics, computational modeling, functional neuroimaging, and analysis of recorded speech, we ask if humans can detect pitch motion using computations analogous to those used by the visual system. We adapted visual stimuli to create novel auditory correlated noise stimuli that elicit robust pitch motion percepts. Crucially, these stimuli are inharmonic and pos
