In many species, females are more sexually attractive to males near ovulation. Some evidence suggests a similar pattern in humans, but methodological limitations prohibit firm conclusions at present, and information on physiological mechanisms underlying any such pattern is lacking. In 202 normally-cycling women, we explored whether women's attractiveness changed over the cycle as a function of...

BACKGROUND People who are perceived as good looking or as having a pleasant personality enjoy many advantages, including higher educational attainment. This study examines (1) whether associations between physical/personality attractiveness and educational attainment vary by parental socioeconomic resources and (2) whether parental socioeconomic resources predict these forms of attractiveness. ...

Despite the recognized advantages that can be obtained in clinical practice when following clinical guidelines (GL), situations of noncompliance with them may emerge. Keeping track of such deviations from the default GL execution, and documenting the physician’s motivations, would clearly be an added value. Moreover, repeated alterations of GL actions (or flow) may highlight the need for an ada...

Do people appear more or less attractive depending on the company they keep? I employed normalization models to predict context dependence of facial attractiveness preferences. Divisive normalization – where representation of stimulus intensity is normalized (divided) by concurrent stimulus intensities – predicts that choice preferences between options increase with the range of option values. ...

T ravelers who use public transport must select a path through the network of available routes. A better understanding of what influences travelers in making this decision would contribute to the design of public transport services in at least two ways. Algorithms that allocate flows of public transport passengers to routes must include some representation of the factors that influence this rou...

More attractive women are more likely to be pursued as mates by men other than their long-term partner and, therefore, to place their partner at greater risk of cuckoldry (investing unwittingly in a child to whom he is genetically unrelated). Men partnered to more attractive women perform more mate retention behaviors – behaviors designed to thwart a woman’s infidelity. With greater risk of fem...

Effect of sexual dimorphism and averageness on the judgment of facial attractiveness was investigated. Participants (n=114) rated attractiveness of 96 facial photographs with neutral expressions. Principal component analyses were conducted on 80 facial feature points standardized via the generalized Procrustes method. Local regression analysis was used to obtain the distribution of attractivene...

Most of what we know about what makes a face attractive and why we have the preferences we do is based on attractiveness ratings of static images of faces, usually photographs. However, several reports that such ratings fail to correlate significantly with ratings made to dynamic video clips, which provide richer samples of appearance, challenge the validity of this literature. Here, we tested ...
