Perceptual task induces saccadic adaptation by target selection
Adaptation of saccades can be induced by different error signals, such as retinal position errors, prediction errors, or reinforcement learning. Recently, we showed that a shift in the spatial goal of a perceptual task can induce saccadic adaptation, in the absence of a bottom-up position error. Here, we investigated whether this top-down effect is mediated by the visibility of the task-relevan...
متن کاملGlobal saccadic adaptation
Our actions need constant calibration to arrive accurately at locations of their intended goals; errors in execution must drive rapid adjustments. As an example, saccadic eye movements are vital for bringing objects of interest into the high-acuity center of vision and they must be continually tuned to compensate for ongoing changes in body, muscle strength and neural variability. This adaptati...
متن کاملLocal contextual interactions can result in global shape misperception.
Adaptation in the visual system frequently results in properties of subsequently presented stimuli being repelled along identifiable axes. Adaptation to radial frequency (RF) patterns, patterns deformed from circular by a sinusoidal modulation of radius, results in a circle taking on the appearance of having modulation in opposite phase. Here we used paths of spatially localized gratings (Gabor...
متن کاملCompetition between color and luminance for target selection in smooth pursuit and saccadic eye movements.
Visual processing of color and luminance for smooth pursuit and saccadic eye movements was investigated using a target selection paradigm. In two experiments, stimuli were varied along the dimensions color and luminance, and selection of the more salient target was compared in pursuit and saccades. Initial pursuit was biased in the direction of the luminance component whereas saccades showed a ...
متن کاملSaccadic Adaptation to Moving Targets
Saccades are so called ballistic movements which are executed without online visual feedback. After each saccade the saccadic motor plan is modified in response to post-saccadic feedback with the mechanism of saccadic adaptation. The post-saccadic feedback is provided by the retinal position of the target after the saccade. If the target moves after the saccade, gaze may follow the moving targe...
