Wyble, Brad; Potter, Mary C.; Bowman, Howard; Nieuwenstein, Mark – Journal of Experimental Psychology: General, 2011
Is one's temporal perception of the world truly as seamless as it appears? This article presents a computationally motivated theory suggesting that visual attention samples information from temporal episodes (episodic simultaneous type/serial token model; Wyble, Bowman, & Nieuwenstein, 2009). Breaks between these episodes are punctuated by periods…

Becker, Stefanie I. – Journal of Experimental Psychology: General, 2010
Current models of visual search assume that visual attention can be guided by tuning attention toward specific feature values (e.g., particular size, color) or by inhibiting the features of the irrelevant nontargets. The present study demonstrates that attention and eye movements can also be guided by a relational specification of how the target…

Heitz, Richard P.; Engle, Randall W. – Journal of Experimental Psychology: General, 2007
A time-course analysis of visual attention focusing (attentional constraint) was conducted in groups of participants with high and low working memory spans, a dimension the authors have argued reflects the ability to control attention. In 4 experiments, participants performed the Eriksen flanker paradigm under increasing levels of speed stress.…

Schmeichel, Brandon J. – Journal of Experimental Psychology: General, 2007
This research tested the hypothesis that initial efforts at executive control temporarily undermine subsequent efforts at executive control. Four experiments revealed that controlling the focus of visual attention (Experiment 1), inhibiting predominant writing tendencies (Experiment 2), taking a working memory test (Experiment 3), or exaggerating…

Prinzmetal, William; McCool, Christin; Park, Samuel – Journal of Experimental Psychology: General, 2005
The authors propose that there are 2 different mechanisms whereby spatial cues capture attention. The voluntary mechanism is the strategic allocation of perceptual resources to the location most likely to contain the target. The involuntary mechanism is a reflexive orienting response that occurs even when the spatial cue does not indicate the…

Awh, Edward; Sgarlata, Antoinette Marie; Kliestik, John – Journal of Experimental Psychology: General, 2005
Models of attentional control usually describe online shifts in control settings that accommodate changing task demands. The current studies suggest that online control over distractor exclusion--a core component of visual selection--can be accomplished without online shifts in top-down settings. Measurements of target discrimination accuracy…

Berger, Andrea; Henik, Avishai; Rafal, Robert – Journal of Experimental Psychology: General, 2005
The relation between reflexive and voluntary orienting of visual attention was investigated with 4 experiments: a simple detection task, a localization task, a saccade toward the target task, and a target identification task in which discrimination difficulty was manipulated. Endogenous and exogenous orienting cues were presented in each trial and…
