The Embodied Origins of Infant Reaching: Implications for the Emergence of Eye-Hand Coordination

Daniela Corbetta, Rebecca F. Wiener, Sabrina L. Thurman, and Emalie McMahon

process of mind formation and have been argued to play an important role in the formation of infants’ behaviors ( Corbetta, 2009 ; Smith & Gasser, 2005 ; Thelen, 2000 ). We discuss the implications of this embodied view for the development of eye-hand coordination in infancy. The Origins of the

Saccade-Related Potentials During Eye-Hand Coordination: Effects of Hand Movements on Saccade Preparation

Uta Sailer, Florian Güldenpfennig, and Thomas Eggert

This study investigated the effect of hand movements on behavioral and electro-physiological parameters of saccade preparation. While event-related potentials were recorded in 17 subjects, they performed saccades to a visual target either together with a hand movement in the same direction, a hand movement in the opposite direction, a hand movement to a third, independent direction, or without any accompanying hand movements. Saccade latencies increased with any kind of accompanying hand movement. Both saccade and manual latencies were largest when both movements aimed at opposite directions. In contrast, saccade-related potentials indicating preparatory activity were mainly affected by hand movements in the same direction. The data suggest that concomitant hand movements interfere with saccade preparation, particularly when the two movements involve motor preparations that access the same visual stimulus. This indicates that saccade preparation is continually informed about hand movement preparation.

The Effect of Neurodegeneration on Visuomotor Behavior in Alzheimer’s Disease and Parkinson’s Disease

Casper de Boer, Johannes van der Steen, Francesco Mattace-Raso, Agnita J.W. Boon, and Johan J.M. Pel

The early stages of neurodegenerative disorders such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) involve deterioration of specific (visuo)motor functions. The aim of the current study was to investigate differences in visuomotor behavior between age-matched groups of 17 patients with AD, 17 patients with PD, and 20 healthy control subjects across three eye-hand-coordination tasks of different cognitive complexity. In two of three tasks, timing and execution parameters of eyes and hand significantly differed between groups. Timing and execution parameters of the eyes and hands could potentially give a quantitative description of disease specific deficits in the spatial and temporal domains and may serve as a tool to monitor disease progression in AD and PD populations.

Perceptual-Motor Abilities of Professional Esports Gamers and Amateurs

Haneol Kim, Seonjin Kim, and Jianhua Wu

-motor skills than amateurs. Among many perceptual-motor skills, anticipation timing, eye–hand coordination, and peripheral perception (field of vision) are critical for esports gamers. As more accurate and faster movements are required to play esports games, professional players often spend a significant

Embedding Perceptual–Cognitive Training in the Athlete Environment: An Interdisciplinary Case Study Among Elite Female Goalkeepers Preparing for Tokyo 2020

Veronique Richard, Béatrice Lavoie-Léonard, and Thomas Romeas

technologies such as virtual reality (VR) and constraint-focused tools such as light reaction training systems (BlazePod™; www.blazepod.com/ ) and eye–hand coordination sticks (HECOstix; https://hecostix.com/ ). VR emerged as a promising tool to support our approach with elite goalkeepers ( Brault et

Effect of Aging on Coordinated Eye and Hand Movements With Two-Segment Sequence

Miya K. Rand and George E. Stelmach

This study examined how aging compromises coordinative eye-hand movements with multiple segments. Older adults and young controls performed two-segment movements with the eyes only or with the eyes and hand together. The results showed minimal age-related changes on the initiation and execution of primary saccade during the first segment. However, the older adults showed a scaling problem of saccade velocity when hand movements were included. They were also slow in stabilizing gaze fixation to the first target. Regarding hand movements, the older adults pronouncedly increased the deceleration phase compared with the controls while fixating their gazes to the target. They also increased the intersegment interval for both eye and hand movements. Taken together, aging differentially affects various components of movements, which contributes to the slowness of overall performance.

Bimanual Coordination Development Is Enhanced in Young Females and Experienced Athletes

David Albines, Joshua A. Granek, Diana J. Gorbet, and Lauren E. Sergio

We characterize bimanual coordination development for the first time in a large sample of children (n = 303) in relation to age, sex, and athletic experience. A further aim is to document the effect of these factors on development to indirectly gain insight into the neural processes that underlie this advanced level of eye–hand coordination. This was a cross-sectional design involving three age groups (range: 9–15 years) that were further separated by sex and level of athletic experience. Participants completed two bimanual tasks and a unimanual control task. While there was no significant change in unimanual movement speed, we observed that females performed the bimanual tasks faster, compared with males. Further, we found that select-level athletes had superior bimanual abilities. Lastly, we found an interaction of sex and skill across age. All groups achieved significant improvement in bimanual coordination with the exception of nonselect males. These data provide a description of normal bimanual coordination development in children during the developmentally crucial ages of 9–15 years, taking account of sex- and experience-related differences.
