Asymmetries In Motor Attention During A Cued Bimanual Reaching Task: Left And Right Handers Compared, Gavin Buckingham, Julie Main, David Carey
Asymmetries In Motor Attention During A Cued Bimanual Reaching Task: Left And Right Handers Compared, Gavin Buckingham, Julie Main, David Carey
Gavin Buckingham
Several studies have indicated that right handers have attention biased toward their right hand during bimanual coordination (Buckingham and Carey, 2009; Peters, 1981). To determine if this behavioral asymmetry was linked to cerebral lateralization, we examined this bias in left and right handers by combining a discontinuous double-step reaching task with a Posner-style hand cueing paradigm. Left and right handed participants received a tactile cue (valid on 80% of trials) prior to a bimanual reach to target pairs. Right handers took longer to inhibit their right hand and made more right hand errors, suggesting that their dominant hand was more …

The current study examined the performance of each limb as it reached across the body (the hard task), while yoked to it’s ipsilateral reaching counterpart (the easy task).
