The Spatial Distribution of Attention within and across Objects
Peer reviewed Peer reviewed
Direct linkDirect link
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…

Spontaneous Gestures during Mental Rotation Tasks: Insights into the Microdevelopment of the Motor Strategy
Peer reviewed Peer reviewed
Direct linkDirect link
Chu, Mingyuan; Kita, Sotaro – Journal of Experimental Psychology: General, 2008
This study investigated the motor strategy involved in mental rotation tasks by examining 2 types of spontaneous gestures (hand-object interaction gestures, representing the agentive hand action on an object, vs. object-movement gestures, representing the movement of an object by itself) and different types of verbal descriptions of rotation.…

Mechanical Invariants Are Implicated in Dynamic Touch as a Function of Their Salience in the Stimulus Flow
Peer reviewed Peer reviewed
Direct linkDirect link
van de Langenberg, Rolf; Kingma, Idsart; Beek, Peter J. – Journal of Experimental Psychology: Human Perception and Performance, 2006
The authors investigated the mechanical basis of length perception through dynamic touch using specially designed rods in which the various moments of mass distribution (mass, static moment, and rotational inertia) were varied independently. In a series of 4 experiments, exploration style and rod orientation were manipulated such that the relative…

Preview Benefit and Parafoveal-on-Foveal Effects from Word N + 2
Peer reviewed Peer reviewed
Direct linkDirect link
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…

Contextual Cueing in Naturalistic Scenes: Global and Local Contexts
Peer reviewed Peer reviewed
Direct linkDirect link
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…

The Scaling of Information to Action in Visually Guided Braking
Peer reviewed Peer reviewed
Direct linkDirect link
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…
