title: [An experimental study on the parallel operation of image: a case of mental rotation].
abstract: The parallel operation of images using mental rotation task was examined from the following two points of view: (1) Whether or not a pair of letter images could be mentally rotated in parallel (Exp. 1), and (2) Whether or not an image pattern composed of two letters could become an object of a single mental rotation (Exp.2). Exp. 1 showed that two images were serially rotated in group S which was slower in rotation of two letter images, while they were rotated in parallel in group F which was faster (Fig. 4). This result was interpreted as a trade-off between the correctness and the speed of response. Exp. 2 showed that the velocity of mental rotation was the same for two-letters image as for one-letter image in both groups, S and F (Fig. 5). This result indicated that the image pattern of two-letters could be an object of a single rotation, and suggested that image processing would include an image register in which multiple images are stored in parallel.
