Oculomotor behaviour in visual search for multiple targets
Abstract:Analysing response time (RT) data from a novel, multiple-target visual search task, Horowitz and Wolfe (2001) found evidence to suggest that the control of attention during visual search is not guided by memory for which of the items or locations within a display have already been inspected. Here, analysis of eye movement data from a similar experiment suggests that RT effects in the multiple-target search task are primarily due to changes in eye movements, and that effects which appeared to reveal memory-free search were actually produced by changes in oculomotor sampling behaviour.
