People occupy multiple social categories simultaneously (e.g., a White female), and this complex intersectionality affects fundamental aspects of social perception. Here, we examined the possibility that infant face processing may be susceptible to effects of intersectionality of sex and race. Three- and 10-month-old infants were shown a series of computer-generated face pairs (5 s each) that d...

This paper shows how parental preferences for sons versus daughters affect divorce, child custody, marriage, shotgun marriage when the sex of the child is known before birth, and fertility stopping rules. We document that parents with girls are significantly more likely to be divorced, that divorced fathers are more likely to have custody of their sons, and that women with only girls are substa...

Sibling Size and Investment in Children's Education: An Asian Instrument This study consistently estimates the trade-off between child quantity and quality by exploiting exogenous variation in fertility due to son preferences. Under son preferences, childbearing and fertility timing are determined conditional on the first child's gender. For the sample of South Korean households I find strong e...

We present a general model for the effect of sex linkage on the evolution of reinforcement of mating preferences on an island. We find that the level of reinforcement can vary up to 80% depending on the mode of inheritance of the female preference and male trait. When reinforcement is driven mainly by selection in the male trait and intrinsic hybrid incompatibilities are weak, sex-linked prefer...

Guidelines proposed by Pennings in 1996 to allow sex preselection ignore ethical problems, basic aspects of human biology and social behavior, cultural differences in reproductive choice availability, and implementation issues. The proposed guidelines would forbid sex preselection for a first child and in cases where gender balance exists. Sex preselection would only be used if the sex select...

Evolutionary approaches to human attractiveness have documented several traits that are proposed to be attractive across individuals and cultures, although both cross-individual and cross-cultural variations are also often found. Previous studies show that parasite prevalence and mortality/health are related to cultural variation in preferences for attractive traits. Visual experience of pathog...

Although parents often try not to favor one child, we examine whether specific environmental factors might bias parents to favor children of one sex over the other. This research draws on theory in evolutionary biology suggesting that investment in female versus male offspring depends on resource availability. Applying this to consumers, a series of experiments show that poor economic condition...

Research in high income countries shows parent-child connectedness to be protective against undesirable sexual and reproductive health (SRH) outcomes among young people. Little has been done to understand the nature of parent-child connectedness, the structural factors that impact on connectedness and parents' understanding of how connectedness affects their children's sexual behaviour in sub-S...

A popular misconception among the general public is that sex offenders most often victimize strangers. To better understand these misconceptions about sex offenders, this study determines the frequency of misperception in the general public and establishes if the misconceptions are related to the policy of sex offender registration. Using a self-administered mail survey, it is found that on ave...
