Abstract
In the present study, we tested right- and left-handed participants in a Poffenberger paradigm with bimanual responses and hands either in an anatomical or in a left-right inverted posture. We observed a significant positive crossed-uncrossed difference (CUD) in RTs for both manual dominance groups and both response postures. These results rule out an explanation of the CUD in terms of stimulus-response spatial compatibility (SRSC) andprovideconvincingevidenceontheimportantroleofinterhemisphericcallosaltransfer in bimanual responding in right- as well as left-handed individuals.| File | Dimensione | Formato | |
