Eye–hand coordination in essential tremor
Movement Disorders, 2006AbstractPatients with essential tremor (ET) or with cerebellar lesions have in common oculomotor abnormalities, with the exception of saccadic eye movements, which do not seem to be involved in ET. Since grasping is prolonged in ET and might be related to saccadic dysmetria, we tested whether simultaneous hand pointing could unmask it.

Eye–hand coordination in goal-directed aiming
Human Movement Science, 2001In a number of studies, we have demonstrated that the spatial-temporal coupling of eye and hand movements is optimal for the pickup of visual information about the position of the hand and the target late in the hand's trajectory. Several experiments designed to examine temporal coupling have shown that the eyes arrive at the target area concurrently ...

Eye—Hand Coordination Asymmetries in Manual Aiming
Journal of Motor Behavior, 2007The authors investigated whether movement-planning and feedback-processing abilities associated with the 2 hand-hemisphere systems mediate illusion-induced biases in manual aiming and saccadic eye movements. Although participants' (N = 23) eye movements were biased in the direction expected on the basis of a typical Müller-Lyer configuration, hand ...

Eye–hand coordination in the newborn.
Developmental Psychology, 1982Are the arm and hand movements of newborns in any way coordinated with vision? If they are, what are the properties of this coordination? These questions were studied in a situation in which newborns were presented with a slowly moving object. In Experiment 1 the number and distribution of arm-hand movements of 14 infants were examined when the object ...

Watching other people move affords observers many benefits such as presenting opportunities for social interactions, deciphering other’s intentions and emotional states, and learning new motor skills. Observational motor learning is the process of learning to perform a novel motor skill by watching others execute that skill. Common coding theories of

Proprioceptive Guidance of Saccades in Eye–Hand Coordination
Journal of Neurophysiology, 2006The saccade generator updates memorized target representations for saccades during eye and head movements. Here, we tested if proprioceptive feedback from the arm can also update handheld object locations for saccades, and what intrinsic coordinate system(s) is used in this transformation.

Eye-hand coordination to visual versus remembered targets
Experimental Brain Research, 2000It has been suggested that the basal ganglia preferentially contribute to movements made to remembered targets, whereas the cerebellum preferentially contributes to movements based on visual cues. Thus, it is possible that eye-hand coordination may differ in these two types of movement.

Field Dependence/Independence and Eye-Hands-Legs Coordination
Perceptual and Motor Skills, 1990A study of the relationship between field-dependence and psychomotor performance is presented. Boys practicing amateur boxing (younger juniors) and 16 to 17 yr. of age were subjects. Field-dependence was assessed on Witkin's Group Embedded Figures Test and eye-hand-legs coordination by means of the SMA-3 coordinometer produced by Bryans Co.

Eye–hand coordination while pointing rapidly under risk
Experimental Brain Research, 2010Humans make rapid, goal-directed movements to interact with their environment. Saccadic eye movements usually accompany rapid hand movements, suggesting neural coupling, although it remains unclear what determines the strength of the coupling. Here, we present evidence that humans can alter eye-hand coordination in response to risk associated with ...

Eye–hand coordination in on-line visuomotor adjustments
NeuroReport, 2014When we perform a visually guided reaching action, the brain coordinates our hand and eye movements. Eye-hand coordination has been examined widely, but it remains unclear whether the hand and eye motor systems are coordinated during on-line visuomotor adjustments induced by a target jump during a reaching movement.
