Saccade Target Selection During Visual Search
Five experiments are reported in which eye movements were recorded while subjects carried out a visual search task. The aim was to investigate whether an accurate initial target directed saccade could be programmed. In experiments 1-2, subjects moved their eyes to targets defined by colour, which were presented with seven non-targets in a circular array. Accurate saccades with short latencies w...
متن کاملPredictive saccade target selection in superior colliculus during visual search.
Searching for a visual object naturally involves sequences of gaze fixations, during which the current foveal image is analyzed and the next object to inspect is selected as a saccade target. Fixation durations during such sequences are short, suggesting that saccades may be concurrently processed. Therefore, the selection of the next saccade target may occur before the current saccade target i...
متن کامل14 Saccade target selection in unconstrained visual search
Our visual system is regularly faced with more information than it can process at once. As a result, our visual experience generally arises from the sequential sampling of visual details by overtly shifting perceptual resources through reorienting the fovea with saccadic eye movements. An emerging view is that this natural visual behavior can be promoted in visual search tasks that do not empha...
متن کاملSaccade target selection in macaque during feature and conjunction visual search.
To gain insight into how vision guides eye movements, monkeys were trained to make a single saccade to a specified target stimulus during feature and conjunction search with stimuli discriminated by color and shape. Monkeys performed both tasks at levels well above chance. The latencies of saccades to the target in conjunction search exhibited shallow positive slopes as a function of set size, ...
متن کاملSaccade target selection in the superior colliculus during a visual search task.
Because real-world scenes typically contain many different potential objects of interest, selecting one goal from many is clearly a fundamental problem faced by the saccadic system. We recorded from visual, movement, and visuo-movement (VM) neurons in the superior colliculus (SC) of monkeys performing a reaction-time visual-search task requiring them to make saccades to an odd-colored target pr...
