Visual Perception: Saccadic Omission — Suppression or Temporal Masking?
Although we don't perceive visual stimuli during saccadic eye movements, new evidence shows that our brains do process these stimuli and they can influence our subsequent visual perception.
متن کاملThe Fastest Saccadic Responses Escape Visual Masking
Object-substitution masking (OSM) occurs when a briefly presented target in a search array is surrounded by small dots that remain visible after the target disappears. The reduction of target visibility occurring after OSM has been suggested to result from a specific interference with reentrant visual processing while the initial feedforward processing is thought to be left intact. We tested a ...
متن کاملVisual masking and visual integration across saccadic eye movements.
The visual world appears unified, stable, and continuous despite rapid changes in eye position. How this is accomplished has puzzled psychologists for over a century. One possibility is that visual information from successive eye fixations is fused in memory according to environmental or spatiotopic coordinates. Evidence supporting this hypothesis was provided by Davidson, Fox, and Dick (1973)....
متن کاملMasking of the achromatic system: Implications for saccadic suppression
Brief (10 msec) increments, presented on a white adapting background, are known to elicit a spectral sensitivity function with a broad mid-spectral peak (King-Smith & Carden, 1976). We have found that a luminance decrement, presented as either a forward or backward mask, dramatically alters the form of the resultant sensitivity function: the broad mid-spectral peak is replaced by a color-oppone...
متن کاملSaccadic suppression precedes visual motion analysis
There is now good evidence that perception of motion is strongly suppressed during saccades (rapid shifts of gaze), presumably to blunt the disturbing sense of motion that saccades would otherwise elicit. Other aspects of vision, such as contrast detection of high-frequency or equiluminant gratings, are virtually unaffected by saccades [1] [2] [3] [4] [5]. This has led to the suggestion that sa...
