Wu, Jiamin; Chan, John S. Y.; Yan, Jin H. – Developmental Science, 2019
We examined the developmental differences in motor control and learning of a two-segment movement. One hundred and five participants (53 female) were divided into three age groups (7-8 years, 9-10 years and 19-27 years). They performed a two-segment movement task in four conditions (full vision, fully disturbed vision, disturbed vision in the…

Hendrickson, Kristi; Mitsven, Samantha; Poulin-Dubois, Diane; Zesiger, Pascal; Friend, Margaret – Developmental Science, 2015
The goal of the current study is to assess the temporal dynamics of vision and action to evaluate the underlying word representations that guide infants' responses. Sixteen-month-old infants participated in a two-alternative forced-choice word-picture matching task. We conducted a moment-by-moment analysis of looking and reaching behaviors as they…

Gozli, Davood G.; West, Greg L.; Pratt, Jay – Cognition, 2012
The present study investigated the mechanisms responsible for the difference between visual processing of stimuli near and far from the observer's hands. The idea that objects near the hands are immediate candidates for action led us to hypothesize that vision near the hands would be biased toward the action-oriented magnocellular visual pathway…

Rich, Anina N.; Mattingley, Jason B. – Cognition, 2010
Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were…

Jannink, Michiel J. A.; Aznar, Miguel; de Kort, Alexander Cornelis; van de Vis, Wim; Veltink, Peter; van der Kooij, Herman – International Journal of Rehabilitation Research, 2009
One of the neuropsychological deficits that can result from a stroke is the neglect phenomenon. Neglect has traditionally been assessed with paper-and-pencil tasks, which are administered within the reaching space of a person. The purpose of this explorative study is to investigate whether it is possible to assess neglect in the extrapersonal…

Wakefield, Claire E.; Homewood, Judi; Taylor, Alan J. – Journal of Visual Impairment & Blindness, 2006
Studies of how children who are blind acquire and use language have focused less on cognitive compensations and more on delays in development. Vision is important in the establishment of early communicative patterns, and sighted children regularly use contextual visual information, such as a speaker's gestures and eye gaze, to make sense of speech…
