Response modes influence the accuracy of monocular and binocular reaching movements.
The authors manipulated the availability of monocular and binocular vision during the constituent planning and control stages of a goal-directed reaching task. Furthermore, trials were completed with or without online limb vision to determine whether monocular- or binocular-derived ego-motion cues influence the integration of visual feedback for online limb corrections. Results showed that the ...

Background : To determine the effect of binocular summation on the time domain transient VEP wave's components. Methods : The monocular and binocular transient visual evoked potentials of 21 normally vision volunteers 18 to 24 years (mean ± SD, 20.7 ± 1.9) during a reversing checkerboard stimulus with spatiotemporal frequency of 2.18-4 cpd-Hz were recorded. The amplitude and latency of N75,...
متن کاملCalibration of Distance and Size Does Not Calibrate Shape Information: Comparison of Dynamic Monocular and Static and Dynamic Binocular Vision
This study investigated the coupling of distance and size perception as well as the coupling of distance and shape perception. Each was tested in 2 ways using a targeted reaching task that simultaneously yielded measures of distance, size, and shape perception. First, feed-forward reaches were tested without feedback. Errors in size did not covary with errors in distance, but errors in shape di...
متن کاملOnline Limb Adjustments
The present investigation sought to examine the nature of the visual information supporting online movement corrections. Participants were instructed to maintain gaze on the veridical endpoint of a neutral Müller-Lyer (ML) confi guration in advance and during reaches performed with and without continuous limb vision. At movement onset, the stimulus array remained either the same (i.e., the neut...
متن کاملDistance estimation in the visual and visuomotor systems
Previous work has demonstrated that monoc-ular vision affects the kinematics of skilled visually guided reaching movements in humans. In these experiments , prior to movement onset, subjects appeared to be underestimating the distance of objects (and as a consequence , their size) under monocular viewing relative to their reaches made under binocular control. The present series of experiments w...
