Perceptual asynchrony: motion leads color.
It is widely accepted that motion and color are processed in separate brain areas of primates. Numerous studies on monkeys suggest that neural mechanisms responsible for motion processing respond faster than those for color. Recent studies on humans, however, provide contradictory evidence. Is this discrepancy due to a gap between species (animal vs. human), or between measures (neurophysiologi...
متن کاملPerceptual asynchrony for motion
Psychophysical experiments show that two different visual attributes, color and motion, processed in different areas of the visual brain, are perceived at different times relative to each other (Moutoussis and Zeki, 1997a). Here we demonstrate psychophysically that two variants of the same attribute, motion, which have the same temporal structure and are processed in the same visual areas, are ...
متن کاملTemporal binding favors the early phase of color changes, but not of motion changes, yielding the color- motion asynchrony illusion
How our binding mechanism judges features as simultaneous remains mysterious. When moving dots alternate in color and motion direction, reports of the perceived color and motion pairing reveal an asynchrony in temporal binding: the motion change best precedes the associated color change by about 150 ms. Here the durations of the motion and color were independently varied. Regardless of motion d...
متن کاملPerceptual asynchrony between color and motion with a single direction change.
When a stimulus repeatedly and rapidly changes color (e.g., between red and green) and motion direction (e.g., upwards and downwards) with the same frequency, it was found that observers were most likely to pair colors and motion directions when the direction changes lead the color changes by approximately 80 ms. This is the color-motion asynchrony illusion. According to the differential proces...
متن کاملAudio–visual interaction in visual motion detection: Synchrony versus Asynchrony
OBJECTIVE Detection and identification of moving targets is of paramount importance in everyday life, even if it is not widely tested in optometric practice, mostly for technical reasons. There are clear indications in the literature that in perception of moving targets, vision and hearing interact, for example in noisy surrounds and in understanding speech. The main aim of visual perception, t...
