The Evaluation Mechanism Of Self-face Attractiveness And The Influence Of Romantic Relationship

Human beings have been explore “ beauty ” for a long time,and the evaluation of “ beauty ” plays an important role in people's social interaction.“ Beauty ” here is actually an important research subject of psychology – “ Facial Attractiveness ”.Facial attractiveness refers to “ the positive and pleasant emotional experience induced by the face of the target person and drives others rising a certain degree of willingness to approach ”.Previous studies have shown that the evaluation of facial attractiveness of others is based on the characteristics of averageness,symmetry and sexual dimorphism feature,and is influenced by the characteristics of the observer.But in these studies,the facial attractiveness is evaluated by others,ignored to explore the mechanism of facial attractiveness evaluated by individual self.Number of studies have shown that the recognition of self-face is different in behavior and brain mechanism from the recognition of faces of others.This means that the evaluation of “ Self-face Attractiveness ” is likely to differ from that of “ Others-face Attractiveness ”,and to be influenced by the characteristics of the observer,romantic relationship,for example.Based on this,this research is going to use cognitive behavior methods and eye-tracking techniques within three studies,to investigate the characteristics of self-face attractiveness evaluation and the impact of love factors systematically.In the first study,we investigated the characteristics of self-face attractiveness evaluation and its intrinsic mechanism,including two experiments(experiment 1 and experiment 2).In experiment 1,duality comparison method,forced selection method and subjective evaluation method were used to investigate the characteristics of selfface attractiveness evaluation,focusing on whether self-face attractiveness evaluation would show positive bias and the degree of this bias.In experiment 2,inverted faces were added as experimental materials to explore whether the specificity of self-face attractiveness evaluation was due to familiarity.Study 2 further examined the impact of romantic relationship on self-face attractiveness evaluation,including one experiment(experiment 3).In experiment 3,single person and lovers were recruited as subjects to explore the influence of love factors on the positive bias of self-face attractiveness evaluation.And added exaggerative attractive faces as experimental materials at the same time,to investigated the degree of positive bias of self-face attractiveness evaluation in lovers.Using eye-tracking technique,the third study examined the features of eye movement in evaluating the attractiveness of single individuals and lovers their own faces,including one experiment(experiment 4),through indicators like fixation number and fixation time.The results show that:(1)the individual showed positive evaluation bias towards self-face attractiveness,and this bias exists steadily(that is,not influenced by the evaluation method).(2)The positive evaluation bias of self-face attractiveness is not a derivative phenomenon of face familiarity effect.(3)Romantic relationships have an impact on the positive evaluation of self-faces' attractiveness,and there are gender differences.(4)The individual in love will also show positive evaluation of the lover's face attractiveness.(5)The enhancement of the positive evaluation bias of self-face by love factor will not exceed the evaluation of exaggerative faces.(6)The evaluation of self-face attractiveness showed a specific recognition pattern of eye movement(mainly reflected in the number of fixation and the fixation time).There were gender differences in eye movement features,but it was not affected by love factors.To sum up,this study explored the behavioral and eye movement characteristics of self-face attractiveness evaluation and the influence of love factors on it.In theory,the results of this study are helpful to understand the basic rules and characteristics of individual evaluation of self-face attractiveness and fill the blank in the field of selfface attractiveness evaluation.It has important theoretical value for promoting the research in the field of face attractiveness.In practice,it can provide a new idea and reference for improving individual happiness and promoting social interaction.
