Dichhaptic task: methodological factors and brain organization.
Significant effects of shape, sequence of shapes, distractors, order of report and practise were demonstrated in a free recall dichhaptic task with nonsense shapes in adults. A left hand superiority (in accordance with theoretical expectations) was observed only in the second reports of the first half of the test. No sex differences were found. There was a preference to report first the right hand, and the opposite preference was observed in a dichhaptic letter task. It is probable that all these methodological factors may have affected previous dichhaptic studies. The association with other lateral and cognitive parameters is also analysed.
