Distance-from-target dynamics during visual search

Tseng, Y. C., & Li, C. S. (2004). Oculomotor correlates of context-guided learning in visual search. Perception & Psychophysics, 66, 1368-1378 noted that visual search with eye movements may be characterized by a search phase in which fixations do not move towards the target, followed by a phase in which fixations move steadily towards the target. They speculated that the phases are related to ...

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...

Visual search has memory: Evidence from multiple target search

Recent studies have proposed two opposing models regarding the function of memory in inefficient visual search, a memory-driven model and a memory-free model. Horowitz and Wolfe (2001) examined the reaction time x n function in a multiple target search task: Participants were required to respond whether there were at least n targets present in the display or not. They demonstrate the positive a...

Object - based target templates guide attention during visual search

Predictive 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...
