The purpose of the present study was to investigate the role of vision and audition in the coordination of in-phase and anti-phase movement patterns at increasing frequency of oscillation in a bimanual linear slide task. The dependent variables were mean error of relative phase and standard deviation of relative phase. Results indicated that vision and audition did not influence the accuracy an...
BACKGROUND AND AIMS The psychometric hepatic encephalopathy score (PHES) is the "gold standard" for minimal hepatic encephalopathy (MHE) diagnosis. Some reports suggest that some cirrhotic patients "without" MHE according to PHES show neurological deficits and other reports that neurological alterations are not homogeneous in all cirrhotic patients. This work aimed to assess whether: 1) a relev...
Functional recovery of the paretic upper extremity eludes the majority of patients post stroke. Although many tasks require the coordinated participation of both hands, rehabilitation strategies for the most part have focused on the paretic limb. This article reviews the behavioral basis of bimanual coordination both in health and after stroke hemiparesis and reviews clinical research studies t...
Most neuropsychological models of dyslexia have focused on left hemisphere dysfunctions; however, several recent studies also suggest difficulties with interhemispheric integration. We assessed that possibility by testing bimanual coordination in 18 dyslexic and 18 nondisabled dextral boys (9-14 years) of above average intelligence on an Etch-a-Sketch-like apparatus. The task measured various r...
Predictions concerning the effects of handedness and attention on bimanual coordination were made from a dynamical model that incorporates the body's lateral asymmetry. Both handedness and the direction of attention (to the left or right) were manipulated in an inphase 1:1 frequency locking task. Left-handed and right-handed participants had to coordinate the planar oscillations of 2 handheld p...
We investigate the cognitive control in polyrhythmic hand movements as a model paradigm for bimanual coordination. Using a symbolic coding of the recorded time series, we demonstrate the existence of qualitative transitions induced by experimental manipulation of the tempo. A nonlinear model with delayed feedback control is proposed, which accounts for these dynamical transitions in terms of bi...
