Abstract
The authors conducted a series of non-visual color recognition experiments on a psychic individual T. I., using five different color sponges ("red, " "yellow, " "green, " "blue" and "black") which were covered with boxes so as to block perception by touch. Two kinds of boxes were used. One was a transparent box which did not obstruct visible light to the target sample, and the other was a black-lined box which obstructed visible light to it. The subject was notified in advance of the kind of the box used in the experiments, but in half of the cases, the subject was intentionally given the false information. Thus, four categorized experiments by combining two kinds of boxes and two types of given information (right and false) were carried out and evaluated. The subject performed 200 trials in each experiment. Every recognition rate was significantly high, but at the same time, it was observed that the recognition rate of experiments using a transparent box was higher than that of a black-lined box, and the recognition rate when the subject was notified of the existence of the transparent box in advance was higher than that of the black-lined box.
