Previous literature suggests that the visual dominance normally resulting from a visual-tactual shape conflict may be eliminated if the conflict is signalled by a cue other than the shape difference per se. The intent of the present study was to provide support for this notion by presenting a visual-tactual shape conflict in which the seen and felt objects were also spatially separated. Contrary to expectation, although a position difference did effectively alert the subject to the presence of a conflict, estimates of shape still reflected the visual and not the tactual information.
以往的文献表明，如果视觉与触觉形状冲突不是由形状差异本身发出信号，而是由其他线索发出信号，那么通常由视觉与触觉形状冲突产生的视觉优势可能会消除。本研究的目的是通过呈现一种视觉与触觉形状冲突来支持这一观点，在这种冲突中，看到的物体和触摸到的物体在空间上也是分开的。与预期相反，尽管位置差异确实有效地提醒了受试者存在冲突，但形状估计仍然反映了视觉信息而非触觉信息。
