Furthermore, hand preference often changed with task repetition, both during training and plateau phases. For human subjects, the hand preference mostly followed the self‐assessment of lateralization by the subjects and the questionnaire (in the latter, right‐handers were more lateralized than left‐handers), except a few discrepancies based on the tube task. There was no hand dominance in seven right‐handers (the other three performed better with the right hand) and in four left‐handers. Five left‐handers showed left‐hand dominance, whereas surprisingly, one left‐hander performed better with the right hand. In the modified Brinkman board task, females performed better than males, right‐handers better than left‐handers.</p> </sec> <sec id="brb3160-sec-0104" sec-type="section"> <title>Conclusions</title> <p>The present study argues for a distinction between hand preference and hand dominance, especially in macaque monkeys.</p> </sec> </abstract> … (more)
