Holmes, Scott A.; Heath, Matthew – Brain and Cognition, 2013
An issue of continued debate in the visuomotor control literature surrounds whether a 2D object serves as a representative proxy for a 3D object in understanding the nature of the visual information supporting grasping control. In an effort to reconcile this issue, we examined the extent to which aperture profiles for grasping 2D and 3D objects…

Purcell, Catherine; Wann, John P.; Wilmut, Kate; Poulter, Damian – Developmental Science, 2012
Almost all locomotor animals are sensitive to optical expansion (visual looming) and for most animals this sensitivity is evident very early in their development. In humans there is evidence that responses to looming stimuli begin in the first 6 weeks of life, but here we demonstrate that as children become independent their perceptual acuity…

Richardson, Michael J.; Marsh, Kerry L.; Schmidt, R. C. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of…

Alvarez, George A.; Horowitz, Todd S.; Arsenio, Helga C.; DiMase, Jennifer S.; Wolfe, Jeremy M. – Journal of Experimental Psychology: Human Perception and Performance, 2005
Multielement visual tracking and visual search are 2 tasks that are held to require visual-spatial attention. The authors used the attentional operating characteristic (AOC) method to determine whether both tasks draw continuously on the same attentional resource (i.e., whether the 2 tasks are mutually exclusive). The authors found that observers…

Iannicelli, Mary M.; McConnaughey, French B. – 1976
Described is a structured, team-teaching, developmental approach for use with multiply handicapped children between the ages of 3 and 7. The program is explained to be child-centered, to involve individualized work and small group lessons, and to use the unit approach. Task analysis and developmental sequencing of skills are performed for each of…
