Dichoptically cancelled motion
We sought to determine whether or not motion-from-texture mechanisms have access to monocular input. Adopting a strategy used by Kolb and Braun (1995. Nature, 377, 336-338), we created drifting textures that were invisible to purely binocular processes. Monocular signals readily conveyed motions defined by local orientation and flicker. However, when left- and right-eye signals were displayed s...
متن کاملA counterchange mechanism for the perception of motion.
A computational model for the perception of counterchange-specified motion is examined in detail and compared with various versions of the Reichardt motion detection model [Reichardt, W. (1961). Autocorrelation, a principle for the evaluation of sensory information by the central nervous system. In W. A. Rosenblith (Ed.), Sensory communication (pp. 303-317). New York: Wiley]. The counterchange ...
متن کاملAuditory Motion Information Drives Visual Motion Perception
BACKGROUND Vision provides the most salient information with regard to the stimulus motion. However, it has recently been demonstrated that static visual stimuli are perceived as moving laterally by alternating left-right sound sources. The underlying mechanism of this phenomenon remains unclear; it has not yet been determined whether auditory motion signals, rather than auditory positional sig...
متن کاملContrasting accounts of direction and shape perception in short-range motion: Counterchange compared with motion energy detection.
It has long been thought (e.g., Cavanagh & Mather, 1989) that first-order motion-energy extraction via space-time comparator-type models (e.g., the elaborated Reichardt detector) is sufficient to account for human performance in the short-range motion paradigm (Braddick, 1974), including the perception of reverse-phi motion when the luminance polarity of the visual elements is inverted during s...
متن کاملThe independent detection of motion energy and counterchange: Flexibility in motion detection
Motion perception is determined by changing patterns of neural activation initiated by spatiotemporal changes in stimulus features. Motion specified by 1st-order motion energy entails neural patterns that are initiated by spatiotemporal changes in luminance, whereas motion specified by counterchange entails oppositely signed changes in neural activation that can be initiated by spatiotemporal c...
