我们如何识别方向错误的物体？一种假设是，我们通过心理旋转的过程将刺激表征标准化为直立的位置，然后识别直立的图像。心理旋转和错误定向物体识别之间关系的反应时间研究产生了模棱两可的结果。我们描述了一个大的右大脑中动脉区域中风的病人，他在三种不同的心理旋转任务中都失败了，但仍然能够识别错误的数字、字母和图画。这种表现模式意味着方向不变的物体识别不依赖于心理旋转。
How are we able to recognize misoriented objects? One hypothesis is that we normalize the stimulus representation to an upright position through a process of mental rotation and then recognize the upright image. Response time studies of the relation between mental rotation and the recognition of misoriented objects have yielded equivocal results. We describe a patient with a large right middle cerebral artery territory stroke who fails three different mental rotation tasks but is nonetheless able to recognize misoriented numbers, letters, and drawings. This pattern of performance implies that orientation-invariant object recognition does not depend upon mental rotation.
