Murray (1997 Memory & Cognition 25 96-105) showed that, when an inverted object was mentally rotated to upright, the reaction time (RT) of flipping strategy (rotating in depth about the horizontal axis) was shorter than that of spinning strategy (rotating in the picture plane). We hypothesised the absence of representation at the intermediate position between the inverted and the upright representations in the flipping strategy, and investigated this hypothesis by a priming paradigm that included prime and probe tasks within one trial. In the prime task, participants were asked to mentally rotate an inverted object to upright. In the probe task, they were asked to judge whether two objects simultaneously presented were the same or different. The flipping strategy in the prime task did not prime the probe task, whereas the spinning strategy did. The present results suggest that there is no intermediate representation in the flipping strategy: the difference in RT between the flipping strategy and the spinning strategy may be attributed to whether there is an intermediate representation or not, which could explain why depth rotation is faster.
默里（1997年，《记忆与认知》第25卷，第96 - 105页）表明，当一个倒置的物体在脑海中旋转至正立状态时，翻转策略（绕水平轴进行深度旋转）的反应时间（RT）比旋转策略（在画面平面内旋转）的反应时间短。我们推测在翻转策略中，倒置表征和正立表征之间的中间位置不存在表征，并通过一种启动范式对这一假设进行了研究，该范式在一次试验中包含启动任务和探测任务。在启动任务中，要求参与者在脑海中将一个倒置的物体旋转至正立状态。在探测任务中，要求他们判断同时呈现的两个物体是否相同。启动任务中的翻转策略并未启动探测任务，而旋转策略则启动了探测任务。目前的结果表明，在翻转策略中不存在中间表征：翻转策略和旋转策略之间反应时间的差异可能归因于是否存在中间表征，这可以解释为什么深度旋转更快。
