The psychology of beauty is complex not just because the concept of beauty is as yet undefined but also because it is largely true that beauty lies in the eyes of the beholder or how individuals perceive other people or things. Beauty can be attributed to everything that appeals to our senses and all objects that are compatible with our personal preferences. Beauty as we perceive it is largely a projection of our needs and beautiful objects or persons simply cater to our idealizations or fancies and reflect our natural need to relate to all that is appealing. Human beings are controlled by the senses and we tend to repeat processes or experiences that appeal to the senses, that are harmonious and have structure and form. Beauty appeals to our sense of sight so there is a preference for repeating the experience of beauty.
But how do we perceive beauty and why are some people or objects considered more beautiful than some others? Psychological tests have considered symmetry and proportion as extremely important in the perception of beauty. Beauty is also more holistic than specific as a beautiful object is judged as a whole package that is appealing rather than judged on the basis of its parts. Freudian or psychoanalytic explanations of beauty are scarce but psychoanalytic concepts could be used to consider our judgment of beauty as a projection or wish fulfillment so people attractive to us are typically ones who we admire or who in some way represent our own desires and fancies. Psychoanalysis can also be compatible with the idea that beauty is preferential perception when there are similarities with a parent. Most people are also considered beautiful when they have baby-faced features or a particular innocence in their faces. Beauty can also be culturally motivated so in certain eastern cultures women with beautiful feet are considered attractive whereas in the Victorian era in England, women with elegance and grace were the ones with smooth neck and tiny waist and modern western women are judged on the basis of their breasts, bottom and lips. The perception of beauty can change and studies have found that women may prefer softer features of men during particular times and more masculine features at other times depending on the stage of their reproductive cycle. So there are actually several theories of beauty which are discussed here one by one.
1. Beauty as Symmetry and Proportion - As you might have noticed in case of ancient architectural marvels, symmetry was extremely important. Whether it was the great pyramids in Egypt or the architectural wonders in Greece, symmetry and perfect dimensions played an important part in the history of aesthetics. This whole idea of symmetry also applies to every other object or person that we perceive so a person with perfectly symmetrical face would also be considered as an epitome of physical perfection. Perfectly shaped and sharp features are attractive to most people and the most beautiful faces are the ones which have very proportionate features. The same applies to the body and the low waist to hip ratio giving a curvy lower part of the body in women is considered more attractive than a straight shape which usually does not indicate fertility. As human beings are finally looking for evolutionary advantage women with a curvy shapes are considered more fertile and are thus more attractive to men. Similarly men with athletic and muscular bodies are attractive to women. However many men might not prefer extremely voluptuous or curvy women just like many women may not prefer extremely muscular men. This suggests that proportion is also about moderation or maybe human beings are more comfortable with certain moderation in what they perceive rather than excess and that way the perception of beauty may even depend on some sort of social programming.
2. Beauty as a whole rather than parts - When we consider something beautiful, we usually try to take a broad holistic view. Thus when we consider a rose as beautiful, we are less attentive towards each petal and consider the symmetry of the flower as a whole. In a similar manner, when we consider the face of a man or a woman, beauty is the composite quality that seems to represent the entire face of the individual rather than the parts or particular features. Our senses prefer a holistic view and perception of things and thus a person is considered attractive or beautiful only when all features add up to something really pleasant to the senses.
3. Beauty as projection and wish fulfillment - The perception of beauty is not only a mental process but also a deeply personal one. If say your lover has blonde hair, you might find other blonde haired people very attractive because you tend to project your inner fancies on to other people. The 'he' looks like my lover or 'she' looks like my lover is a common syndrome in our perception of beauty and people who are remotely similar to our mates are suddenly more beautiful to us than others. The same projection applies in case of selecting a mate who resembles a parent. If a man looks like your father or a member of the family he is obviously far more attractive to you than to others. The wish fulfillment theory is also equally true and when we want to be like someone in terms of talents or certain qualities, we naturally consider that person as absolutely perfect and beautiful. Some teenagers may idolize popular actors or actresses and the need to be like them also determines their own perception of beauty.
4. Beauty as innocence and charm - No one can deny that a charming personality with social confidence can be far more attractive than a dull personality. A person who has the inherent ability to attract individuals with the sheer force of personality and presence is considered highly attractive. In some way there may be an association between good looks and social confidence and sometimes individuals with good looks are also socially most accepted and thus more confident. Individuals with baby-face features with high or defined cheekbones and certain innocence on their faces are usually considered very attractive by both the sexes. Beauty is advantageous in social adaptation and good looking people are thus socially successful as well, as they get support and positive assessment from other people. However the opposite in also true and sometimes good looking women and even men can become extremely self-conscious and fail to develop adequate self confidence. Good looks can in certain cases become an impediment as good looking women who are also intelligent may be judged more on the basis of their looks rather than their intelligence and this is sometimes a sad fact in modern society.
5. Beauty as a product of culture and society - This is an accepted fact. The concept of beauty seems to change with time as society changes and the perception of beauty varies in different cultures. Dark skin is considered very attractive in Western societies and whiter skin is considered as attractive in Eastern societies, because of the element of novelty in both the cases. Feet and hair of women are important features in Eastern cultures whereas in the West, the woman's lips, and hips are considered important. The breasts of women are important indicators of beauty in all cultures and men's body and chin or jaw and certain masculine sharpness are also considered as attractive. Studies have indicated that women however tend to prefer dominant looking men during the first follicular stage in their reproductive cycle but prefer men with softer more feminine features when they are in their menstrual and ovulation stages. This may have some evolutionary advantage as men with feminine soft natures and faces are considered as more stable and more family oriented than men who have extreme masculinity or a sort of raw appeal. This is however too generalized and there are individual differences as well.
