Androgen dynamics in the context of children's peer relations: an examination of the links between testosterone and peer victimization

Testosterone levels have been shown to decrease in the face of social defeat in several mammalian species. Among humans, the loss of social status has been studied primarily in the context of athletic competition, with winners having higher testosterone levels than losers. This study examined testosterone levels in relation to peer victimization (bullying) in a sample of 151 boys and girls aged 12–13. Statistically controlling for age and pubertal status, results indicated that on average verbally bullied girls produced less testosterone and verbally bullied boys produced more testosterone than their nonbullied counterparts. Similar trends were evident comparing social and physical bullying with testosterone. Sex differences are discussed in terms of empirically validated differences in coping styles, as girls tend to internalize, whereas boys tend to externalize, their abuse. Aggr.

The physiology of women’s power motive: Implicit power motivation is positively associated with estradiol levels in women

This study examined the relationship between implicit power motivation (n Power) and salivary estradiol in women. Forty participants completed the Picture Story Exercise, a measure of n Power, and salivary estradiol levels from two saliva samples were determined with radioimmunoassay. We found that n Power was positively associated with estradiol levels. The positive correlation between n Power and estradiol was stronger in single women and women not taking oral contraceptives than in the overall sample of women. These findings replicate those of Stanton and Schultheiss (2007), giving further credence to the argument that women’s dominance striving is positively associated with their endogenous estradiol levels and that both social and biological factors influence the nature of that association.     

Effects of sex,status, and mating cues on expected aggressive responses

The effect of sex, status, and mating cues on expected aggression was examined via three scenario‐based studies in which participants imagined themselves in a situation with a same‐sex instigator of a provocation. Participants were randomly assigned to receive a scenario, which included one of two levels of status of instigator (high, low), one of two levels of attractiveness of the instigator (unattractive, attractive), and one of two levels of provocation (apology, insult). Sex and dispositional aggressivity were also included in a full factorial design. Based on evolutionary psychology ideas, we anticipated that status and attractiveness would differentially influence expected aggression for men vs. women. Participants in Experiment 1 were instructed to imagine that they were alone, whereas participants in Experiments 2 and 3 imagined themselves in a situation that included mating‐related primes. In general expected aggression was greater for aggression‐prone participants and under conditions of provocation and/or a high‐status instigator. Experiments 2 and 3 found that, in the context of mate competition, sex differences in the effects of instigator provocation, status, and attractiveness emerged: greater aggressivity now only predicted more aggression for males but not females who were insulted; aggression was highest for females confronting an unattractive, high‐status instigator and for males confronting an attractive, high‐status instigator; females were more likely to aggress against a high‐status instigator, regardless of being in a steady relationship or a first date situation, but males were only more likely to aggress against a high‐status instigator in a first date situation.

The higher they are,the harder they fall: The effects of wrongdoer status on observer punishment recommendations and intentionality attributions

In two studies, we explore whether the status of a wrongdoer affects observers’ attributions for the wrongdoer’s actions and opinions about the wrongdoer’s deserved punishment. We find that observers attribute greater intentionality to the actions of high status wrongdoers than the identical actions of low status wrongdoers, and consequently recommend more severe punishments for the former than the latter. Additionally, we find that the relationship between a wrongdoer’s status and observers’ attributions is driven by observers’ perceptions of the wrongdoer’s underlying social motives: high status wrongdoers are presumed to be more interested in their own welfare (self-concerned), and less interested in the welfare of others (other-concerned), than low status individuals. These findings have implications for the psychology of retributive justice, and suggest that punitive reactions may be influenced as much by characteristics of the criminal as they are by characteristics of the crime.     

The effect of conspicuous consumption on men’s testosterone levels

Using evolutionary psychology as a theoretical framework, it is argued that conspicuous consumption serves as a means by which men communicate their social status to prospective mates. Accordingly, men’s endocrinological responses, particularly their testosterone levels, are responsive to fluctuations in their status as triggered by acts of conspicuous consumption. Study 1 reports that men’s testosterone levels increased and decreased partially (directionally), after driving an expensive sports car and an old family sedan, respectively. Additionally, the location of the drive, either a busy downtown area or a semi-deserted highway, partially moderated this response. Study 2 demonstrates that when men’s social status was threatened by the wealth displays of a male confederate in the presence of a female moderator, their testosterone levels increased. This is suggestive of an evolved mechanism for responding to intra-sexual challenges. Collectively, these constitute the first set of studies to measure hormonal outcomes in consumer behavior.     

Effects of a 6-week circuit training intervention on body esteem and body mass index in British primary school children

Research examining the impact of physical activity on children's body image has been limited and equivocal. The current researchers examined the effect of 6-week circuit-based training on body esteem and body mass index (BMI) in 68 British children (34 boys and 34 girls, aged 10–11 years, 16% overweight, 7% obese). The Body Esteem Scale for Children (BES-C) was administered to both the intervention group and control group, pre, post and 6 weeks post the intervention. BMI was directly assessed from height and body mass pre- and post-intervention. The results of this study revealed that, as compared to the control group, participation in 6-week circuit training significantly improved body esteem scores post-intervention. However, these scores were not sustained 6 weeks post-intervention. The improvement in body esteem scores from pre- to post-intervention was greater for girls as compared to boys. Additionally, BMI decreased significantly in the intervention group compared to the control group.     

Hormonal response to competition in human males

Changes in testosterone (T) and cortisol (C) were evaluated in males competing in a non-athletic laboratory reaction time task. Subjects were randomly assigned to “win” or “lose” by adjusting feedback regarding their task performance. Further, subjects were randomly assigned to either a Close Contest condition (where one person barely “defeated” his opponent), or a Decisive condition (in which the victory was clear). Throughout competition, samples of saliva were taken and assayed later for T and C. Post-competition mood and attributions were also measured. Winners had higher overall T levels than losers, with no significant difference between Close Contest or Decisive Victory conditions. In contrast, C levels did not differ between winners and losers nor did Condition (Close or Decisive) have any effect. Mood was depressed in Decisive losers compared to all other groups. The results indicate that the perception of winning or losing, regardless of actual performance or merit on the task, differentially influenced T (but not C) levels, and that such hormonal changes are not simply general arousal effects but are related to mood and status change.     

Short-term effects of residence on the testosterone responses to fighting in alpha male guinea pigs

The short-term effects on testosterone (T) levels of (a) taking blood samples, (h) fighting in one's own home cage, and (c) fighting in another male's home cage were examined in eight alpha male guinea pigs, each living together with two females and two subordinate males in their home cages for 4 months. Every male was given two 5-minute agonistic encounters, one in his home cage and one in another male's home cage. After the encounter, intruder males were returned to their home cages. Three blood samples were taken 10 minutes before and 5 and 45 minutes after the agonistic encounters (sampling times were designated as 0, 20, and 60 minutes, respectively). One week before the agonistic encounters were conducted, blood samples were taken from each male on the same time schedule (0, 20, and 60 minutes). The main findings were as follows: (1) the animals showed an increase in T-levels after an agonistic encounter in their home cages and a decline in T-levels after an agonistic encounter in the home cages of other alpha males' irrespective of being the winner or the loser and the degree of escalation during the encounter; (2) the smaller the differences in T-titers between both opponents 10 minutes before the encounter, the more escalated the agonistic encounter.     

Rethinking Economic Inequality

Secular discourse about problem of economic inequality rests on two foundational premises that are problematic from a theological point of view. First, individuals enter into society with the aim of bettering their own condition. Second, bettering one's own condition entails accruing more wealth and power so that one can fulfill more of one's desires. In this paper I argue that insofar as these premises shape market behavior, they actively promote excessive economic inequality. Ethical responses to the problem of economic inequality that do not challenge these assumptions are unlikely to effectively promote justice. A theological response to the problem of economic inequality should work to promote cultural change by reminding us that genuine human flourishing depends on communal ties and the higher human goods that material wealth is properly meant to support.
