Women’s Sexual Compliance with Male Dating Partners: Associations with Investment in Ideal Womanhood and Romantic Well-Being

Sexual compliance involves willing acquiescence to unwanted sex for the good of the relationship. Northeastern U.S. undergraduate women in exclusive relationships (N?=?193) anonymously reported on their sexual behaviors and motives, investment in ideal womanhood, and romantic well-being. About 37% (n?=?72) reported sexual compliance. As expected, sexually compliant women reported greater investment in ideal womanhood than non-compliant women, although unexpectedly, they reported less overall satisfaction and similar commitment. Women’s compliance was motivated more by pursuing relationship enhancement than by avoiding conflict. Regardless, only avoidance motives were associated (negatively) with relationship satisfaction. Compliant women who reported more frequent compliance motivated by conflict avoidance reported particularly low satisfaction. These findings challenge conceptualizations of women’s sexual compliance as beneficial.     

The Eysenck psychoticism dimension and delinquent behaviours among non-criminals: changes across the lifespan?

This study assessed relationships between scores on Eysenck's psychoticism (P) scale and delinquent behaviours among high school and university students. Respondents were 347 high school students (M AGE=15.34 years) and 220 first-year university students (M AGE=19.11 years). There were notable differences across the two groups. Whereas most delinquency items correlated significantly with P among the school students, this was not the case among the university students. It is concluded that, while the P scale predicts most delinquent behaviours among younger respondents, it best predicts more serious delinquent behaviours among non-criminal adults. The results are discussed in the context of previous research using the P scale.     

Birth weight and cognitive ability in childhood: a systematic review

Individual differences in cognitive ability may in part have prenatal origins. In high-risk (low birth weight/premature) babies, birth weight correlates positively with cognitive test scores in childhood, but it is unclear whether this holds for those with birth weights in the normal range. The authors systematically reviewed literature on the relationship between normal birth weight (more than 2,500 g) and childhood intelligence in term (37-42-week gestation) deliveries. Six studies met the inclusion criteria, and the authors present a comprehensive narrative review of these studies. There was a small, consistent, positive association between birth weight and childhood cognitive ability, even when corrected for confounders. Parental social class accounted for a larger proportion of the variance than birth weight, and these 2 variables were largely independent.
