The subjects were 19 children ranging from 5 years and 3 months to 11 years and 9 months in age who visited the department of pediatric dentistry, The Nippon Dental University, School of Dentistry at Niigata. For this study, we produced test images by videotaping them during treatment with a visicon eye camera. The test images recording with images of a dentist, a hygienist, and the child subject's mother throughout it, which is an imitation of the field of vision of a child from lying on his back in the dental chair during treatment, and concerning voice, in the beginning of the recording, “Okuchi wo aite (Open your mouth)” was asked by the dentist, a moment later “Iiko ni shitene (Be good)” was said by mother, and then “Ganbattane (Hang in there)” was said by the dental hygienist.
We took it that the children are receiving audio-visual stimulus while they are being addressed, and measured their eye movements with the aid of the eye camera during this period. By means of visicon eye camera, we recorded the child subjects' eye movements when the voices were let out. The subjects who scanned three talking persons were classified as scanning group, or else non-scanning group.
To make certain if there is any personality traits in the two groups, we performed Hayashi's quantification theory type II multivariate analysis and examined the measurements of eye movements in comparison with the Takagi-Sakamoto juvenile personality inventory.
The findings are as follows.
1. According to the result of Hayashi's quantification theory type II, The correlation ratio was 0.701: the discriminant ratio was 94.7% and the discriminant point was -0.127.
2. Among the Takagi-Sakamoto juvenile personality inventory, the items of self-control, self-assertiveness, nervosity and adaptability to school life had effects on the eye movement.
3. Concerning personality traits, the partial correlation coefficient of 0.700 over was showed between self assertiveness and nervosity, nervosity and autonomy, anxious tendency and sociality, self-contrl and personal stability, respectively.
The result of analyses revealed that there are some personality traits in the scanning group and the non-scanning group.
