Forty adults and 40 children, all right-handed, were presented with either of two series of six nonsense shapes to palpate: Those who were divided into sections by grid lines and thus provided categorical information or those who provided a whole shape and coordinate information that could be processed globally. Subjects were given an Input condition where they formed a mental representation of the shape while palpating the unseen tactual stimulus with either hand, followed by an Evaluation condition in which they attempted to solve the task by generating and using the previously stored image. Evaluation response times showed that the left hemisphere was significantly faster at generating images from categorically stored information. Neither hemisphere had an advantage when generating an image from globally stored information.
40名成年人和40名儿童，均为右利手，被给予两组由六个无意义形状组成的序列中的一组进行触摸：一组是被网格线划分成部分从而提供分类信息的形状，另一组是提供可以整体处理的完整形状和坐标信息的形状。受试者被给予一个输入条件，即他们用任意一只手触摸看不见的触觉刺激物时形成形状的心理表征，随后是一个评估条件，在该条件下他们试图通过生成和使用先前存储的图像来解决任务。评估反应时间表明，左半球从分类存储的信息中生成图像的速度明显更快。当从整体存储的信息中生成图像时，两个半球都没有优势。
