Hollingworth, Andrew; Maxcey-Richard, Ashleigh M.; Vecera, Shaun P. – Journal of Experimental Psychology: Human Perception and Performance, 2012
Attention operates to select both spatial locations and perceptual objects. However, the specific mechanism by which attention is oriented to objects is not well understood. We examined the means by which object structure constrains the distribution of spatial attention (i.e., a "grouped array"). Using a modified version of the Egly et…

Brockmole, James R.; Castelhano, Monica S.; Henderson, John M. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2006
In contextual cueing, the position of a target within a group of distractors is learned over repeated exposure to a display with reference to a few nearby items rather than to the global pattern created by the elements. The authors contrasted the role of global and local contexts for contextual cueing in naturalistic scenes. Experiment 1 showed…

Kliegl, Reinhold; Risse, Sarah; Laubrock, Jochen – Journal of Experimental Psychology: Human Perception and Performance, 2007
Using the gaze-contingent boundary paradigm with the boundary placed after word n, the experiment manipulated preview of word n + 2 for fixations on word n. There was no preview benefit for 1st-pass reading on word n + 2, replicating the results of K. Rayner, B. J. Juhasz, and S. J. Brown (2007), but there was a preview benefit on the 3-letter…

Franz, V. H.; Scharnowski, F.; Gegenfurtner, K. R. – Journal of Experimental Psychology: Human Perception and Performance, 2005
The authors tested whether the effects of the Ebbinghaus illusion on grasping are corrected during late phases of the movement. Surprisingly, the grasp aperture was corrected neither under no-vision (N = 52) nor under full-vision (N = 48) conditions. The authors show that previous reports of a correction (e.g., S. Glover & P. Dixon, 2002a) are due…

Fajen, Brett R. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Braking to avoid a collision can be controlled by keeping the deceleration required to stop (i.e., ideal deceleration) in the "safe" region below maximum deceleration, but maximum deceleration is not optically specified and can vary as conditions change. When brake strength was manipulated between participants using a simulated braking task, the…
