What’s the chance that a man’s kids are not really his, biologically?
d Saad looks at a fascinating study examining rates of nonpaternity: The standard nonpaternity rate that is most commonly mentioned across cultural settings is 10%. This is quite extraordinary in that it is difficult to imagine that 1 out of every 10 children is sired by someone other than the man who is recognized as the father. Turns out this figure is far too low. And far too high as well. Don't worry, I'll explain. In the past many studies…

Do nice guys really finish last?
pular culture often describes being nice as a social disadvantage. However, research repeatedly finds that being agreeable is associated with a number of advantages. Literature noting the positive benefits of being agreeable is reviewed. The paper also addresses how agreeableness, one of the Big Five personality dimensions, is linked with higher-quality friendships, successful parenting, better academic and career performance, and health. The case is made that being agreeable is not equated to being easily influenced nor is it an artifact…

A Woman’s Level Of Sexual Satisfaction Can Predict Her Mental And Physical Health
ructural equation modelling was used to assess the strengths of the links between sexual satisfaction and self-reported (a) relationship well-being, (b) mental health, and (c) physical health for women in same-sex (i.e., homosexual, n = 114) versus mixed-sex (i.e., heterosexual, n = 208) relationships. Participants came from a large-scale Internet study. Sexual satisfaction was found to be an extremely strong predictor of relational well-being, a strong predictor of mental health, and a weak to moderately strong predictor of physical health.…

Can you tell if a woman is fertile by the way she walks?
investigated variations in gait between women at high and at low conception probability, and how men rated those variations. Women participated in a motion capture study where we recorded the kinematics of their walking patterns. Women who were not using hormonal contraception (n = 19) repeated the study during the late follicular stage and the luteal stage of their menstrual cycle. Using a discriminant function analysis, we found significant differences in walking behavior between naturally cycling women at their follicular and…

Can psychopaths assess vulnerability just by watching someone walk?
is study examines whether psychopathic traits in a nonreferred (and presumably nonpsychopathic) sample could enhance the accuracy of perceptions of victim vulnerability. In a previous study, the interpersonal and affective component of psychopathy was associated with increased accuracy in assessing vulnerability in dyadic conversations, and Grayson and Stein (1981) established that vulnerability could be assessed by observing targets walking. The purpose of this study was to determine whether individuals scoring higher on psychopathic traits would be better able to judge…

The secrets to a good apology
esults indicated that relationships recovered significantly when offending partners used behaviors labeled as explicit acknowledgment, nonverbal assurance, and compensation." Therapists and theologians claim that the process of forgiveness is essential to the restoration of damaged relationships, but this possibility has received limited empirical attention. Furthermore, the role of an offender's communicative behavior in the forgiveness process remains understudied. This project first analyzed an inductively derived list of communication behaviors to develop a taxonomy of forgiveness-seeking approaches used by 186 romantic…

Is there a reason why some women like a guy with chest hair and other women don’t?
has commonly been considered that women’s preference with regard to male body hair changes over the years according to fashion and is influenced by the media. Experimental evidence, however, is currently lacking. We examined the effect of male torso hairiness on Finnish women’s attractiveness ratings by presenting pictures of male torsos before and after the removal of body hair. We found that the women’s preferences correlated strongly with the hairiness of their current partners, suggesting that body hair may…

Does letting your teenager drink at home make them more or less likely to binge drink?
e current study examined whether permitting young women to drink alcohol at home during senior year of high school reduces the risk of heavy drinking in college. Participants were 449 college-bound female high school seniors, recruited at the end of their senior year. Participants were classified into one of three permissibility categories according to their baseline reports of whether their parents allowed them to drink at home: (a) not permitted to drink at all; (b) allowed to drink with family…
