A Novel Method for Disentangling Strategies from Visual Search

Vicente Pallarés, Lorena Rami, Laura Dempere-Marco

Abstract

The process of actively scanning a visual scene while looking for something in a cluttered environment is known as visual search. In this work, we show that it is possible to disentangle the strategies pursued by subjects to solve visual tasks by investigating dynamical aspects inherent to eye-tracking data. A novel method is proposed to characterize visual search strategies in a generalized N-dimensional feature domain, which allows us to investigate spatial-temporal aspects of the search as well as the subjects’ reliance on visual cues. In order to validate the proposed method, we have developed an experimental paradigm based on a double conjunction search in which one the visual cues is systematically manipulated, which can induce featurebased strategies in the observers. On the basis of the preliminary evidence presented here, we argue that this characterization of visual search strategies opens new avenues to assess cognitive function and its relation to normal aging.
