Can the magnitude of the binocular depth contrast effect be predicted solely by the induction of disparity information?
” Perception 28 ECVP Abstract Supplement Can the magnitude of the binocular depth contrast effect be predicted solely by the induction of disparity information? T Hudson, W Li, L Matin We propose that the binocular depth contrast effect (BDC) is not simply due to disparity induction. Rather, BDC is effected by retinal orientation and binocular disparity information. Parallel pitched lines produce bilaterally symmetric retinal image orientations. For example, topforward pitched lines in the RVF (LVF) produce clockwise (anticlockwise) rolled retinal images. If BDC were based solely on roll induction, the sign of induction would change when the test line crossed the median plane; if BDC were based solely on disparity induction, the sign of induction would not change. Four subjects set the pitch of a plane containing a luminous test line to appear erect in the presence of a variably pitched luminous induction line. The T-line and I-line were either on the same or opposite sides of the medi
