Visual search is the act of looking for a predefined target among other objects. This task has been widely used as an experimental paradigm to study visual attention, and because of its influence has also become a subject of research itself.

Certain visual stimuli evoke perceptions of discomfort in non-clinical populations. We investigated the impact of stimuli previously judged as uncomfortable by non-clinical populations on a visual search task. One stimulus that has been shown to affect discomfort judgments is noise that has been filtered to have particular statistical properties (Juricevic et al, 2010 Perception 39 884-899). A ...
متن کاملVisual Representation Determines Search Difficulty: Explaining Visual Search Asymmetries
In visual search experiments there exist a variety of experimental paradigms in which a symmetric set of experimental conditions yields asymmetric corresponding task performance. There are a variety of examples of this that currently lack a satisfactory explanation. In this paper, we demonstrate that distinct classes of asymmetries may be explained by virtue of a few simple conditions that are ...
متن کاملVisual search — 1 VISUAL SEARCH ACROSS THE LIFE SPAN
The focus of this study was to evaluate the gains and losses in visual search performance across the lifespan in a representative sample of 298 individuals ranging from 6 to 89 years of age. Adopting a lifespan developmental perspective, two general resource theories were considered: cognitive speed and inhibitory control. Participants searched computer displays to indicate the presence or abse...
