Distortion of Space and Time during Saccadic Eye Movements
The space-time distortion perceived subjectively during saccadic eye movements is an associative phenomenon of a transient shift of observer’s visual frame of reference from one position to another. Here we report that the lines of subjective simultaneity defined as two spatially separated flashes perceived during saccades were nearly uniformly tilted along the physical time-course. The causali...
متن کاملThe role of presaccadic compression of visual space in spatial remapping across saccadic eye movements
When multiple bars are briefly flashed near the saccadic goal on a visual reference just before a saccade, the total width of the multiple bars appears to be compressed toward the saccadic goal. We show that presaccadic compression of visual space is related to the attribution of the displacement of a visual stimulus to the displacement of another stimulus appearing after the saccade. Subjects ...
متن کاملExpansion of visual space after saccadic eye movements.
Human subjects reported the perceived two-dimensional location of a visual target that was briefly presented after a saccade in the absence of visual references. Consistent with previous studies, immediately after horizontal saccades, there was a salient horizontal component in mislocalization in the direction opposite to the saccade. However, the horizontal component in mislocalization was not...
متن کاملSaccadic eye movements and cognition.
Scanning of the visual scene is an important selective process in visual perception. In this article we argue that eye-movement data provide an excellent on-line indication of the cognitive processes underlying visual search and reading. We outline some recent advances from physiological investigations of saccadic eye-movement control before focusing on eye-movement behaviour in visual search a...
متن کاملTime-optimality and the spectral overlap of saccadic eye movements.
Saccades exhibit remarkably stereotypical motor behavior, both in their bell-shaped velocity trajectories and in their peak velocity–amplitude and duration–amplitude relationships (the “main sequence”). It is sometimes assumed that this is the result of the system optimizing for movement duration, although no direct empirical evidence as such exists. However, formal time-optimal (“bang-bang”) m...
