| The attractiveness evaluation of the face is affected not only by physical factors, but also by non-physical factors. This thesis analyzed the general characteristics and individual differences of the observers' eye movements when they are grading the attraction of the highly attractive female facial images.In this study, the Eye link II eye tracking system was used to record 63 subjects'eye movements. The subjects were randomly divided into two groups. In group A (experimental group), the subjects were requested to grade the attraction of 7 female face images. In group B (control group), the subjects were requested only to observe these female face images. The Myers-Briggs Type Indicator assessment and the Field Cognition Mode test were carried out on every subject. The highly scored and most consistent images were analyzed.By comparing the eye movement differences between subjects on evaluation state and those on non-evaluation state, the study demonstrated that, in general indicators, the average saccade distance of the former was significantly smaller than that of the latter; while in the interest zone indicators, the total dwell time of the former was significantly longer than that of the latter in the left eye and nose interest area; In evaluation state, the fixation count was more than that in non-evaluation state in the nose interest area.Then eye movements in evaluation state were further analyzed. The data demonstrated that the nose interest area was the key part in the procession of evaluation. Among the different areas in face, the nose was not only most frequently and enduring noticed, but also most preferred to be noticed. In this article, it was named the Preferred Facial Characteristic (PFC).The individual difference of the evaluators in eye movements was analyzed. Three factors:gender, personality type and cognitive style were taken into account. The data demonstrated that (1) there was no gender difference between male and female when comparing their overall eye movements, or their interest-area eye movements; (2) Categorized by the Myers-Briggs Type Indicator, subjects of different personality types of cognitive processing laid emphases on different interest areas in the face. Subjects of F type paid more attention in mouth area than those of T type, Subjects of P type paid more attention in eye area than those of J type. Subjects of P and J process in different ways in mouth area. (3) On research of the Field Cognition Mode, the first gaze duration in nose area of the field-independent subjects was significantly greater than those of the field-dependent type, and which was thought to be related to cognitive processing strategy.The conclusions of this thesis are below:Firstly, there were significant differences between observers in evaluation state and those in non-evaluation state. Secondly, nose was more noticed as a preferred facial characteristic in evaluation state, but not in non-evaluation state. Thirdly, the evaluator factor had impact on attractiveness rating, such as personality type and cognitive style. But there was no significant difference between male and female, and which may be relate to the Aesthetic Convergence between the Opposite Sex and the Same sex. |
