Perspective Morphometric Criteria for Facial Beauty and Proportion Assessment

Common sense usually considers the assessment of female human attractiveness to be subjective. Nevertheless, in the past decades, several studies and experiments showed that an objective component in beauty assessment exists and can be strictly related, even if it does not match, with proportions of features. Proportions can be studied through analysis of the face, which relies on landmarks, i.e., specific points on the facial surface, which are shared by everyone, and measurements between them. In this work, several measures have been gathered from studies in the literature considering datasets of beautiful women to build a set of measures that can be defined as suggestive of female attractiveness. The resulting set consists of 29 measures applied to a public dataset, the Bosphorus database, whose faces have been both analyzed by the developed methodology based on the expanded set of measures and judged by human observers. Results show that the set of chosen measures is significant in terms of attractiveness evaluation, confirming the key role of proportions in beauty assessment; furthermore, the sorting of identified measures has been performed to identify the most significant canons involved in the evaluation.

Lower Waist-to-Hip, Waist-to-Stature, and Waist-to-Bust Ratios Predict Higher Rankings of Plus-size Models in a Naturalistic Condition

Previous research suggests that waist-to-hip ratio (WHR), waist-to-stature ratio (WSR), and waist-to-bust ratio (WBR) serve as cues of health and fertility in women, influencing the viewers’ perception of attractiveness. However, it is unclear to what extent these findings can be applied to the perception of female attractiveness in a naturalistic condition or in women with a higher body mass index. In this study, we tested whether lower WHR, WSR, and WBR increased the perceived attractiveness of plus-size models in a naturalistic condition. The WHR, WSR, and WBR were computed via biometric data (height, bust, waist, and hip measurements) of 49 U.S. plus-size models who have been listed on ranker.com. The photographs of these models have been viewed 2.60 million times and voted 146,000 times. The perception of attractiveness was operationalized as rankings, generated from the relative number of upvotes and downvotes from site visitors. Spearman correlations showed that lower WHR, WSR, and WBR were all positively correlated with higher rankings. In a subsequent ordinal logistic regression, only WSR and WBR remained as significant predictors of rankings. The principal component regression also revealed that the latent body component of WHR, WSR, and WBR predicted rankings of the models.These findings cannot be accounted by the models’ general popularity or their anthropometric measures being similar to other types of models’ (e.g., fashion, glamor, playboy, and adult film models). Our findings suggest that smaller WHR, WSR, and WBR influence the perception of female attractiveness in a naturalistic condition, even among plus-size models.

Implications of nutritional stress as nestling or fledgling on subsequent attractiveness and fecundity in zebra finches (Taeniopygia guttata)

The conditions an organism experiences during early development can have profound and long lasting effects on its subsequent behavior, attractiveness, and life history decisions. Most previous studies have exposed individuals to different conditions throughout development until nutritional independence. Yet under natural conditions, individuals may experience limitations for much shorter periods due to transient environmental fluctuations. Here, we used zebra finches (Taeniopygia guttata) in captivity to determine if conditions experienced during distinctly different early developmental phases contribute differently to male and female attractiveness and subsequent reproduction. We conducted a breeding experiment in which offspring were exposed to food regimes with (a) low quality food provided only during the nestling period, (b) low quality food provided only during the fledgling period, or (c) high quality food throughout early development. We show that despite short-term effects on biometry and physiology, there were no effects on either male or female attractiveness, as tested in two-way mate choice free-flight aviary experiments. In a subsequent breeding experiment, the offspring from the initial experiment were allowed to breed themselves. The next generation offspring from mothers raised under lower quality nutrition as either nestling or fledging were lighter at hatching compared to offspring from mothers raised under higher quality nutrition whereas paternal early nutrition had no such effects. The lack of early developmental limitations on attractiveness suggests that attractiveness traits were not affected or that birds compensated for any such effects. Furthermore, maternal trans-generational effects of dietary restrictions emphasize the importance of role of limited periods of early developmental stress in the expression of environmentally determined fitness components.

THE IMPACT OF FEMALE ATTRACTIVENESS IN SPY

This thesis discusses the impact of female attractiveness on the female character which is related to the way Spy sees attractive women and what the impacts to them are. There are criteria for female attractiveness that are displayed by the film such as physical attributes and traits. In order to show the criteria of attractive women and the responses that they get, I use stereotyping theory. Women who are physically attractive get better treatment, but in order to get that, they have to dress with a certain style that men favor. For the women who are considered as unattractive, they will be ignored by men. In conclusion, I find out that the appearance and the attitude of the female character still depend on men’s view. Women can also be seen as attractive from their characteristics. Attractiveness also has huge influences on the way women get treated by men.
