Cross-domain adaptation reveals that a common mechanism computes stereoscopic (cyclopean) and luminance plaid motion

Across three experiments, this study investigated the visual processing of moving stereoscopic plaid patterns (plaids created with cyclopean component s defined by moving binocular disparity embedded in a dynamic random-dot st ereogram). Results showed that adaptation to a moving stereoscopic plaid or its components affected the perceived coherence of a luminance test plaid, and vice versa. Cross-domain adaptation suggests that stereoscopic and lum inance motion signals feed into a common pattern-motion mechanism, consiste nt with the idea that stereoscopic motion signals are computed early in the motion processing stream.
