The Whole is Other Than the Sum: Perceived Contrast Summation Within Color and Luminance Plaids
The apparent contrast of a plaid is a reflection of the neural relationship between the responses to its two orthogonal component gratings. To investigate the perceived contrast summation of the responses to component gratings in plaids, we compared the apparent contrasts of monocular plaids to a component grating presented alone across chromaticity and spatial frequency. Observers performed a ...
متن کاملThe McCollough effect with plaids and gratings: evidence for a plaid-selective visual mechanism.
We investigate if adapting to colored plaids produces a McCollough effect on plaids or gratings and if adapting to colored gratings produces a McCollough effect on plaids. We find that the answer is unambiguously yes in all cases, though the strength of the effect differs significantly depending on the inducing and testing stimuli. Furthermore, we show that plaids and gratings can simultaneousl...
متن کاملEvidence for a Feature Tracking Explanation of Why Type II Plaids Move in the Vector Sum Direction at Short Durations
When two moving sinusoidal gratings, with similar spatial frequency, contrast, phase, but different orientation are combined to form a plaid, their perceived direction of motion has been predicted by the intersection of constraints rule (IOC) (Adelson & Movshon, Nature, 300, 523-525, 1982). However, at short durations (60 msec) the direction of perceived motion has been predicted by the vector ...
متن کاملExposure duration affects the perceived direction of cyclopean Type II plaids
This study investigated the effect of exposure duration on the perceived direction of cyclopean Type I and Type II plaids moving in the X/Y plane. The cyclopean plaids were created from grating components defined by binocular disparity embedded in a dynamic random-dot stereogram. The results showed that the cyclopean Type I plaid appeared to move in the intersection-of-constraints (IOC) directi...
متن کاملVisual motion of missing-fundamental patterns: motion energy versus feature correspondence
Missing-fundamental gratings, generated by subtracting the fundamental Fourier components from square-wave gratings, appear to move backward when presented in quarter-cycle jumps, even though their edges and features all move forward. We used variants of these stimuli to test current models of motion perception. We found that missing-fundamental plaids, constructed from orthogonal missing-funda...
