Abstract
Subject, Mr.H.Yamashita, being bandaged up his eyes by cotton towel, being seated in a chair during test. He faced a target on the table and told us about what it was.
(1) Under nuorecents lamps light with about 350 luxas room light, the face Patterns of ESP card, square, round, cross, star and waves, were faultlessly distinguished.
(2) The region, where the target was seen, was a triangular prism, its basal plane faced subject's bandaged face and side planes were opposite.
(3) A rectangular screen appeared in the region, and the color and/or the shape of target which existed only on the screen, that is to say, he looked like seeing a movie or watching a television.
(4) The illumination on the target had an effect on the time lag for Perception. Under the lower illumination, his chairvoyant ability was suppressed and needed more time for perception, i. e. the relativity between illumination and time lag were 0.2/15 ...... 350/1(lux/sec). And the threshold of perception was approximately 0.1lux.
(5) The color of target had an effect on the time lag. Black and white were the fddastest perceived color, and brown was the latest one.
(6) The color of the base where the target put on had an effect on the time lag. 0range and green promoted his clairvoyant ability, but white prolonged.
