通过两个实验研究了优势右探索手和非优势左探索手以及左物体方向和右物体方向对熟悉物体触觉识别的影响。在实验1中，被试在两个区块中命名48个熟悉的物体。有没有优势手的优势，命名对象触觉和探索手和对象取向之间没有相互作用。此外，命名的启动并没有减少任何对象的方向或探索手的变化。为了测试这些结果是否归因于未能编码对象取向和探索手，实验2重复实验1，除了在第二块中的意外任务是决定是否探索手或对象取向相对于初始命名块发生了变化。在这两项任务上的表现都高于偶然性，这表明在最初的命名块之后，这些信息已经被编码成长期的触觉表示。因此，当识别熟悉的对象时，触觉处理系统可以在手部变化和对象取向变化中有效地实现对象恒定性，尽管该信息即使在其与任务无关时也经常被存储。
Two experiments were carried out to examine the effects of dominant right versus non-dominant left exploration hand and left versus right object orientation on haptic recognition of familiar objects. In experiment 1, participants named 48 familiar objects in two blocks. There was no dominant-hand advantage to naming objects haptically and there was no interaction between exploration hand and object orientation. Furthermore, priming of naming was not reduced by changes of either object orientation or exploration hand. To test whether these results were attributable to a failure to encode object orientation and exploration hand, experiment 2 replicated experiment 1 except that the unexpected task in the second block was to decide whether either exploration hand or object orientation had changed relative to the initial naming block. Performance on both tasks was above chance, demonstrating that this information had been encoded into long-term haptic representations following the initial block of naming. Thus when identifying familiar objects, the haptic processing system can achieve object constancy efficiently across hand changes and object-orientation changes, although this information is often stored even when it is task-irrelevant.
