The Area Activation Model of Saccadic Selectivity in Visual Search
We present an approach towards a simple, explicit model of saccadic selectivity in visual search tasks. The model in its present state includes weights for target-distractor similarities and fixation field size as its only adjustable parameters. Based on these, the model predicts the statistical distribution of saccadic endpoints for any given visual search display. Besides providing an explici...
متن کاملArea activation: a computational model of saccadic selectivity in visual search
The Area Activation Model (Pomplun, Reingold, Shen, & Williams, 2000) is a computational model predicting the statistical distribution of saccadic endpoints in visual search tasks. Its basic assumption is that saccades in visual search tend to foveate display areas that provide a maximum amount of taskrelevant information for processing during the subsequent fixation. In the present study, a co...
متن کاملSaccadic selectivity in complex visual search displays
Visual search is a fundamental and routine task of everyday life. Studying visual search promises to shed light on the basic attentional mechanisms that facilitate visual processing. To investigate visual attention during search processes, numerous studies measured the selectivity of observers' saccadic eye movements for local display features. These experiments almost entirely relied on simple...
متن کاملRunning head: SACCADIC SELECTIVITY DURING VISUAL SEARCH
The current study examined the relation between the difficulty of central discrimination and the efficiency of peripheral selection in visual search tasks. Participants were asked to search for a target among high-, medium-, and low-similarity distractors. In Experiment 1, while the duration of current fixations increased with increasing target-distractor similarity, there was no evidence that ...
متن کاملMapping the Color Space of Saccadic Selectivity in Visual Search
Color coding is used to guide attention in computer displays for such critical tasks as baggage screening or air traffic control. It has been shown that a display object attracts more attention if its color is more similar to the color for which one is searching. However, what does similar precisely mean? Can we predict the amount of attention that a display color will receive during a search f...
