This is a report of the studies, continued from the previous work, as regards the mode and law of modification of imaged, by the experiment on imagery fusion which is observed in a post-hypnotic hallucinatory state. We investigated chiefly whether these images where integrated according to the configuration law of the Gestalt school, or whether they were nothing other than the overlapping of images.<BR>Various experiments were performed, using according figures (Fig. 1), discordant figures (Fig. 3), the composite images partly changed in size (Fig. 4), the incomplete figures with concrete meanings (Fig. 5. A) and the figures in which perception and meaning were discordant with each other (Fig. 6). The results were as follows :<BR>1. There were some subjects whose images were clear, and others whose images were vague. In general the iamges were clear in the deep hypnotic trance, and vague in the medium trance.<BR>2. In the case if the clear images, they were prominently overlapped, while in the case of the vague images, they overlapped one another and were disjointed or integrated.<BR>3. After conditioning two kinds of figures with two kinds of sounds, a composite iamge could be around by the two stimuli. In this case by changing the tempo of one kind, a part of the composite image was changed. This fact would prove that the composite images were combinations of elements.<BR>4. In the case of the integrated images, the modification of both clear and vague images could be explained satisfactorily not by the Gestalt theory but by the intervention of the meaning. Moreover, the hypothesis of the hierarchy of cerebral functions corresponding to these phenomena was possible.<BR>5. Modification through meaning was more frequent in the vague images than in the clear ones.<BR>6. The spontaneous effect of meaning on the images was dependent on the depth of trance. This effect was comparatively weak in deep trance and strong in medium trance. It was assumed that in mudium trance which reproduced the integrated images, meaning activity still remained.<BR>7. Having presented incomplete figures with concrete meaning to examine the effect of meaning, it was clear that the modification of images by meaning took place distinctly under the influence of suggestion.<BR>8. If perception and meaning of the figure were made to be in discord with each other, the meaning suggested at the time of conditioning produced more effect on the modification of the images than that at the time of recall.
