ロールシャッハ検査施行中におけるGSRの変化

抄録

The present investigation was undertaken to examine the emotional disturbance induced by Rorschach cards in an ordinary test situation and its possible relationship with the formation of test performances therein. The emotional disturbance was checked through changes in GSR.
Experiment I : Thirty university students served as one group of subjects. The other group consisted of twenty psychoses in the Inokashira Mental Hospital, Tokyo. Each subject was administered the Rorschach test individually, during which the continual measurement of GSR was made. The order of the presentation of the Rorschach cards was systematically rotated and the modified Latin square design was employed so that it may counteract the adaptation effect of GSR and may also preserve as nearly as possible the normal Rorschach sequence. GSR records were analysed ; (A) by initial change upon the presentation of each card, (B) by the sum total of changes during the period each card was presented and (C) by the total number of frequency.
In sheer contrast to the performance of the normal group, the psychotic group showed marked increases of GSR during the period when card VI, card VII and colored cards VIII, IX, X were presented (Fig. 1). Statistical analysis revealed that this group for there existed a significant difference between the non-colored and the colored cards (Table 2). In Rorschach test performances, a relatively high frequency of color and color-form responses of psychoses was noted (Table 3). The mean number of verbal responses in the psychoses' group showed decreases upon card VI, card VII and complete colored cards (Fig. 2). Experiment II : Instead of Rorschach cards, seven color stimuli were projected, and the concomitant changes in GSR were read. One group consisted of 21 students, the other 21 psychoses. No significant difference between these two groups was noted (Fig. 3). The implication is that the color stimuli without form-elements, by themselves, might not induced any significant difference between the two.
Experiment III : Another twenty university students served as subjects. The procedure was kept the same as in Exp. I except that two additional cards were presented before the ordinary Rorschach cards. This procedure was adopted as the result of careful examinations of the results of Exp. I, in which the effect of position of cards in the series was found highly significant and might cover a possible difference between colored and non-colored cards.
The effect of positions in the series was eliminated (Fig. 4). The result revealed that even in the normal group there was the significant difference between the reactions toward card V and complete colored card VIII, but nevertheless the difference between the cards was found statistically insignificant (Fig. 5, Table 5 and 6).
In conclusion, while the mere existence or non-existence of color on the cards does not disturb the emotionality of the subject significantly, colored cards induce emotional disturbance, especially upon the emotionally ill-controlled subjects, when perceptual activities set in. It might be argued therefore that with such subjects the presence of color hinders their perceptual activities and arouses their emotionality which, in turn, casts further limits upon perceptual activities and consequently is apt to deteriorate Rorschach performances. Normal Subjects in which form perception dominates show less emotional disturbance and a relatively low frequency of color responses.
