Beesley, Tom; Hanafi, Gunadi; Vadillo, Miguel A.; Shanks, David R.; Livesey, Evan J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2018
Two experiments examined biases in selective attention during contextual cuing of visual search. When participants were instructed to search for a target of a particular color, overt attention (as measured by the location of fixations) was biased strongly toward distractors presented in that same color. However, when participants searched for…

Hocking, Darren R.; Thomas, Daniel; Menant, Jasmine C.; Porter, Melanie A.; Smith, Stuart; Lord, Stephen R.; Cornish, Kim M. – Developmental Science, 2013
Previous studies suggest that individuals with Williams syndrome (WS), a rare genetically based neurodevelopmental disorder, show specific weaknesses in visual attention and response inhibition within the visuospatial domain. Here we examine the extent to which impairments in attentional control extend to the visuomotor domain using a…

Liu, Charles C.; Wolfgang, Bradley J.; Smith, Philip L. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Recent spatial cuing studies have shown that detection sensitivity can be increased by the allocation of attention. This increase has been attributed to one of two mechanisms: signal enhancement or uncertainty reduction. Signal enhancement is an increase in the signal-to-noise ratio at the cued location; uncertainty reduction is a reduction in the…

Simpson, Tamara; Camfield, David; Pipingas, Andrew; Macpherson, Helen; Stough, Con – Educational Gerontology, 2012
In an increasingly aging population, a number of adults are concerned about declines in their cognitive abilities. Online computer-based cognitive training programs have been proposed as an accessible means by which the elderly may improve their cognitive abilities; yet, more research is needed in order to assess the efficacy of these programs. In…
