Bilateral Transfer of a Visuomotor Task in Different Workspace Configurations.

Bilateral transfer occurs when a learned behavior transfers from one (group of) effectors(s) to another. Researchers investigating bilateral transfer of a visuomotor adaptation task between limbs used across workspaces have observed divergent results. This study assessed whether bilateral transfer of a visuomotor adaptation task changes with workspace configuration manipulation.

Aging reduces manual dexterity and force production asymmetries between the hands.

Age-related effects on motor asymmetry provide insight into changes in cortical activation during aging. To investigate potential changes in manual performance associated with aging, we conducted the Jamar hand function test and the Purdue Pegboard test on young and older adults. All tests indicated reduced motor asymmetry in the older group.

Attentional focus effects on joint covariation in a reaching task.

Adopting an external focus of attention (EF) has been found beneficial over internal focus (IF) for performing motor skills. Previous studies primarily examined focus of attention (FOA) effects on performance outcomes (such as error and accuracy), with relatively less emphasis on movement coordination. Given that human movements are kinematically and kinetically abundant (Gefland & Latash, 1998), FOA instructions may change how motor abundance is utilized by the CNS.

Cursor movements to targets labelled "stop": a kinematic analysis.

The label 'Stop' potentially generates conflict-signifying important corrective action, or a warning not to touch. To examine potential conflict between an incongruent label (i.e.

Incompatibility Influences Cursor Placement When Pointing to Images of Cups.

Objective: As images are used within graphical user interfaces to signify menu selection, it is important to understand how image properties can influence cursor placement online.

Background: Objects have multiple dimensions that create potential ambiguity and Stroop-like confusions for the operator if a previously response conflicts with the response.

Methods: To examine the impact of compatibility and other contextual factors, 41 participants used a computer Mouse or touch screen to place the cursor upon images of full or empty cups that varied in size, and direction of handle.
