Dimensionality in rhythmic bimanual coordination.
Newell and Vaillancourt (2001) hypothesized that the dimensionality of motor behavior is a function of the level of task performance and the task dynamic. The present study examined high (in-phase), moderate (antiphase) and low (45°, 90°, and 135° relative phase) levels of task performance in bimanual coordination. Estimates of dimensionality were calculated for the component (effector movement...
متن کاملConstraints on Coordination Intrinsic dynamics, behavioral information and asymmetry in bimanual rhythmic coordination
Rhythmic interlimb coordination arises from the interaction of intrinsic dynamics and behavioral information, i.e., intention, memory and/or external information specifying the required coordination pattern. This study investigates the influence of the content of memorized behavioral information on coordination in musically experienced and inexperienced subjects. These groups are hypothesized t...
متن کاملEffector dynamics of rhythmic wrist activity and its implications for (modeling) bimanual coordination.
To examine the role of the effector dynamics of the wrist in the production of rhythmic motor activity, we estimated the phase shifts between the EMG and the task-related output for a rhythmic isometric torque production task and an oscillatory movement, and found a substantial difference (45-52 degrees) between the two. For both tasks, the relation between EMG and task-related output (torque o...
متن کاملAttention and Handedness in Bimanual Coordination Dynamics
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...
متن کاملConnecting Cortical And Behavioral Dynamics: Bimanual Coordination
For the paradigmatic case of bimanual coordination, we review levels of organization of behavioral dynamics and present a description in terms of modes of behavior. We briefly review a recently developed model of spatiotemporal brain activity that is based on short- and long-range connectivity of neural ensembles. This model is specified for the case of motor and sensorimotor units embedded in ...
