In this study, the glances gap was added as a new condition to the conventional experiments on psychological territory, in order to verify its effect on psychological territory. We also examined the relationship between the results and personality traits of examinees, such as version (intro/extro) or anxiety about others' glances. The results has shown the following three major points; 1) By being looked away (performed by the person being approached), there is an effect of reducing a mental stress for the "comforts" in all directions outside the distance-range of 120cm. Similarly, the approacher's mental stress for the "comforts" is also reduced outside the distance-range of 210cm. 2) The effect of the glances gap on the mental stress for "conversation" is small, mainly affecting within the distance-range in frontal direction of the approacher. 3) The group with high version and low score in anxiety have smaller mental stress for the "comforts" under various conditions within the vision angle of 0° and the distance-range of 120 to 180cm compared to those with low version and high score in anxiety. In other words, the personality trait implies the potential difference of mental stress for the "comforts" with establishing eye contact at close range.
