Interactions between new and pre-existing dynamics in bimanual movement control.
28 Jun 2009 
Motor skills are commonly acquired through practice. This process not only involves acquisition of the particular task demands but also requires overcoming pre-existing modes. In the present study, interactions between new and intrinsic dynamics ...

The impact of real and illusory target perturbations on manual aiming.
28 Jun 2009 This experiment was designed to determine if real and illusory shifts in target position at movement initiation affect the same online corrective processes. Adult participants completed rapid goal-directed movements toward the vertex of a target "T" ...

Saccades and prefrontal hemodynamics in basketball players.
28 Jun 2009 We investigated saccade performance and prefrontal hemodynamics in basketball players with different skill levels. Subjects were 27 undergraduate basketball players and 13 non-athlete undergraduates (control group: CON). The players were divided ...

Sensory information in perceptual-motor sequence learning: visual and/or tactile stimuli.
28 Jun 2009 
Sequence learning in serial reaction time (SRT) tasks has been investigated mostly with unimodal stimulus presentation. This approach disregards the possibility that sequence acquisition may be guided by multiple sources of sensory information ...

28 Jun 2009 BACKGROUND: Frailty in older adults, defined as a constellation of signs and symptoms, is associated with abnormal levels in individual physiological systems. We tested the hypothesis that it is the critical mass of physiological systems abnormal ...

Disentangling perceptual from motor implicit sequence learning with a serial color-matching task.
25 Jun 2009 This paper contributes to the domain of implicit sequence learning by presenting a new version of the serial reaction time (SRT) task that allows unambiguously separating perceptual from motor learning. Participants matched the colors of three small ...

24 Jun 2009 Recent global events have focused attention on the potential threat of international and domestic chemical terrorism, as well as the possibility of chemical warfare proliferation. Sulphur mustard (SM) is one of the potent chemical warfare agents ...

Optimal control predicts human performance on objects with internal degrees of freedom.
24 Jun 2009 On a daily basis, humans interact with a vast range of objects and tools. A class of tasks, which can pose a serious challenge to our motor skills, are those that involve manipulating objects with internal degrees of freedom, such as when folding ...

Perceptual influence on bimanual coordination: an fMRI study.
23 Jun 2009 In bimanual coordination subjects typically show a spontaneous preference for movement symmetry. While there is experimental evidence for the principle of muscle homology, recent evidence suggested that bimanual coordination may be mediated as ...

23 Jun 2009 BACKGROUND: Although the "learning curve" is commonly analyzed by splitting the data into arbitrary chunks of experience, this does not allow for precise estimation of where the curve plateaus or the rate at which learning is achieved. Our objective ...
