Dichhaptic recognition of textures in normal adults.
Dichhaptic procedures usually use nonsense shapes or letters as stimuli. The present study was designed to investigate hand asymmetry in a texture recognition task, in male right-handed adults. An overall left hand (right hemisphere) advantage was observed. However, when examining the order-of-report effect, the asymmetry appeared for the first report only. These results are discussed in terms of inter-hemispheric cooperation that can emerge for the second report.
