Aims: This paper examines the relationship between observational behavior and the observers' result assumptions, using a contained diagram that includes significant non-verbal information, such as gestures. The ability of care workers to assess a patient's mental status on the basis of non-verbal information would be considered an important skill necessary to understanding patient condition.
Methods: One hundred and eleven subjects were asked to take a test exploring two types of psychological status, and their eye movements were monitored during testing. Path analysis was used to examine the relationships among eye movements, individual personalities, and test results.
Results: In stimulus 1, the neuroticism of the personality was determined. In stimulus 2, openness was determined in the range of eye movement. There is a relationship between the total length of eye fixation time and the answer time at the eye fixation point. Although there was no significant influence found in stimulus 1, the openness still tended to influence the eye fixation point.
Conclusions: The eye fixation point increased among those people with high openness scores. It was theorized that they attempted to obtain information from the stimulus being provided.
