Testing the Attentional Dwelling Hypothesis of Attentional Capture
Journal of Cognition, 2018 Researchers are strongly divided as to whether abrupt onsets capture spatial attention in a purely stimulus-driven fashion or contingent on their search goals.

Visual search elicits the electrophysiological marker of visual working memory. [PDF]
PLoS ONE, 2009 BACKGROUND:Although limited in capacity, visual working memory (VWM) plays an important role in many aspects of visually-guided behavior. Recent experiments have demonstrated an electrophysiological marker of VWM encoding and maintenance, the ...

Everything is Foreseen, Yet Free will is Given (Mishna Avot 3:15)
Journal of Cognition, 2018 Jan Theeuwes’ review of visual selection shines a useful spotlight on the role of selection history in determining subsequent deployments of attention. However, he blurs an important distinction between volition and top-down guidance of attention and he ...

Sit-and-Wait Strategies in Dynamic Visual Search [PDF]
, 2003 The role of memory in visual search has lately become a controversial issue. Horowitz and Wolfe (1998) observed that performance in a visual search task was little affected by whether the stimuli were static or randomly relocated every 111 ms.

The roles of symbolic and numerical representations in asymmetric visual search
Acta Psychologica, 2021 This study aims to explore the impact of symbolic and numerical representations in asymmetric visual search. Heterogeneous and homogeneous mathematical units, letters, symbols and numbers were used in the first and second experiments, respectively ...

The psychophysics of visual search
Vision Research, 2000 Most theories of visual search emphasize issues of limited versus unlimited capacity and serial versus parallel processing. In the present article, we suggest a broader framework based on two principles, one empirical and one theoretical. The empirical principle is to focus on conditions at the intersection of visual search and the simple detection and

Is countershading camouflage robust to lighting change due to weather? [PDF]
Royal Society Open Science, 2018 Countershading is a pattern of coloration thought to have evolved in order to implement camouflage. By adopting a pattern of coloration that makes the surface facing towards the sun darker and the surface facing away from the sun lighter, the overall ...

Effects of age and eccentricity on visual target detection
Frontiers in Aging Neuroscience, 2014 The aim of this study was to examine the effects of aging and target eccentricity on a visual search task comprising 30 images of everyday life projected into a hemisphere, realizing a ± 90° visual field.

The Attentional Capture Debate: When Can We Avoid Salient Distractors and When Not?
Journal of Cognition, 2023 There has been a long-standing debate concerning whether we are able to resist attention capture by salient distractors. The so-called “signal suppression hypothesis” of Gaspelin and Luck (2018) claimed to have resolved this debate.

Vision Research, 2001 The accuracy of saccade localisation during visual search was examined for a search target defined by the single features of orientation or depth or by a conjunction of the two features. Subjects were required to move their eyes to the target which appeared in one of eight possible locations, arranged circularly around fixation, with non-targets ...
