Abstract:
|
Past research has suggested that performance on tactile temporal ordering
judgments (TOJ) depends on both the location of the hands and the tools. When judging which hand was presented with one of two vibrotactile stimuli presented to
each hand at varying intervals, accuracy levels decreased both when the hands were
crossed and when the tools were crossed. This effect of tool crossing alone has been
interpreted as evidence for the incorporation of tools into the body schema. However, the studies presented here suggest no effect of tool position on
performance. Subjects performed a tactile TOJ with tools task in four conditions: hands and tools uncrossed, hands crossed with the tools uncrossed, hands uncrossed with the tools crossed, and both the hands and tool crossed. Results show a strong
effect of hand location, but no effect of tool location, with performance in the hands
uncrossed with the tools crossed condition remaining comparable to the hands and tools uncrossed condition. In addition, our findings suggest an interaction between sex and response type, in which female performance when responding with foot
pedals, as opposed to with the tools, decreases significantly. This effect was not true
for males. This may suggest a difference in the way males and females map somatotopic and external space. Implications for the incorporation of tools into the body schema are discussed. |
