The article presents the results of an empirical study of the sexual characteristics of the sense of symmetry. At the same time, the phenomenological analysis of the variety of forms and directions of the manifestation of the characteristics of symmetry in the surrounding world allowed us to define the concept of “sense of symmetry” as a sensory experience caused by the mental reflection of the degree of order, balance and proportionality of objects and phenomena. Based on the idea of differential signs of emotional response depending on gender, an assumption was made about the significant role of this factor in the emotional
reflection of symmetry and its violation. The presented quantitative data allow us to assert the sexual specificity of the development of a sense of symmetry. In particular, it was found that the attitude to symmetry in the group of female subjects is more homogeneous than in the group of male subjects. This specificity of the attitude to symmetry is manifested in a greater intra-group spread of indicators of a sense of symmetry among male subjects, with a relatively uniform distribution of the results of female subjects. In addition, the data obtained indicate that the sexual characteristics of the perception of facial symmetry and its violations are more clearly expressed in the time of detection of asymmetry, in the relationship of speed with accuracy, in which girls are superior to boys.
