Do friends share similar body image and eating problems? The role of social networks and peer influences in early adolescence

This study examined the role of friendship networks and peer influences in body image concern, dietary restraint, extreme weight loss behaviours (EWLBs) and binge eating in a large community sample of young adolescent females. Based on girls' self-reported friendship groups, social network analysis was used to identify 173 friendship cliques. Results indicated that clique members shared similar scores on measures of dieting, EWLB and binge eating, but not body image concern. Average clique scores for dieting, EWLB and binge eating, were also correlated significantly with clique averages on measures of perceived peer influence, body mass index and psychological variables. Multiple regression analyses indicated that perceived peer influences in weight-related attitudes and behaviours were predictive of individual girls' level of body image concern, dieting, EWLB use and binge eating. Notably, an individual girl's dieting and EWLB use could be predicted from her friends' respective dieting and EWLB scores. Findings highlight the significance of the peer environment in body image and eating problems during early adolescence.     

Effects of performance anxiety on effort and performance in rock climbing: a test of processing efficiency theory

Three studies examined the effort and performance of rock climbers in the context of processing efficiency theory. Anxiety was manipulated by different means in the three studies. In each study, the effort due only to the physical exertion of climbing was controlled for. Anxiety, effort, and performance were measured via self-report, an integrated heart rate measure, and belayer observation. Consistent with processing efficiency theory, the results showed that higher levels of anxiety were usually associated with higher levels of effort and commensurately higher levels of performance. However, the results also suggested that cognitive anxiety may not be the prime determinant of the effort and performance changes observed. Finally, the results suggested that other individual difference variables may play an important part in determining the extent to which individuals may be able to make use of anxiety-induced effort.     

White Picket Fences,White Innocence

Focusing on the cultural implications of the relationship between white segregationist Senator Strom Thurmond and his biracial daughter Essie Mae Washington‐Williams, this essay explores national narratives of whiteness, femininity, morality, and the institutionalization of sexual violence against black women.     

Perceived calorie intake and state body-image satisfaction in women attempting weight loss: A preliminary investigation

State body-image satisfaction levels (BIS) can be predicted by appearance concerns, eating attitudes and body mass index (BMI). Determinants of state BIS and its variability were examined in women attempting weight loss. Little is known about contextual cues that influence state BIS; therefore the effect of eating on BIS was examined. Forty-six females attending a commercial weight loss group completed measures of shape and weight concerns, appearance beliefs and dietary restraint, followed by completion of a diary that assessed state BIS, mood and perceived calorie intake immediately following evening meals. Regression analysis indicated that after controlling for mood, state BIS was associated with higher BMI and dietary restraint. Greater variability in state BIS was associated with greater variability in perceived calorie intake. This relationship was fully mediated by greater variability in mood. The findings imply that state BIS warrants investigation as a process that may influence weight loss management.     

Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Commentaries on “Reconsidering the path for neural and physiological methods in consumer psychology”

The initial version of the article by Clithero, Karmarkar, Nave, and Plassmann (Journal of Consumer Psychology, 2024) was critiqued by open comments from a small group of scholars. Their suggestions encouraged the authors to clarify challenging relationships between brain processes and emotions, beliefs, and actions. The revision expanded fMRI and EEG to include measures of vision, facial expression, breathing, heart rhythms, and blood chemistry. The paper provides multiple avenues of joint work between neurological and psychological scholars. The comments below reflect different reactions to the final article. Wes Hutchinson acknowledges that neuroscience insights complement cognitive measures that generate explicit measures of thought, emotion, or preferences, but he warns that repeated measures over time are problematic for both types of measurement, and the inherent complexity of brain–behavior relationships is often underestimated. With both orientations, understanding the functioning of human behavior is akin to making sense of an orchestra, where the interactive blending of different instruments and musicians reflects a complex activity that generates sounds, emotions, and stories. Both consumer neuroscientists and psychologists need to broaden their paradigmatic approaches with bodily measures and advanced psychological procedures to overcome challenges to joint progress. Martin Reiman asserts that despite difficulties with measures that have different levels of abstraction or velocity, research has provided remarkable associations between brain activity and consumer behavior. Effective studies merging brain and behavior can effectively proceed with studies that differ in two dimensions: first, by altering the number of variables, and second, by shifting whether the scientific paradigm is inductive or deductive. In its simple form, the Excavation path explores brain activity when a person is exposed to specific statements or emotions. In its most challenging form, Integrative Studies generate predictions from theories that test the convergent validity of divergent measures and leverage skills from different researchers. Studies reflecting high levels on one dimension but low levels on the other can also provide fruitful research opportunities. Brian Knutson, like Reimann, counters the idea that consumer psychology has not lived up to its promises. He references studies showing that activity from very specific areas of the brain reliably predicts choices better than explicit ratings or choices. Such research generates deductions from increasingly precise neural maps that enable confirmation of theory. That said, he acknowledges that consumer neuroscience is not able to identify a brain button that would alter choice through manipulated neurostimulation. However, since human brains are similar across people, the depth of neural insights that are consistent across a small sample of 40 respondents may generate greater insights than conventional marketing research with 2000 respondents. The cost of neuroscience will further decrease with gains in reliability, validity, and generalizability, particularly if augmented with bodily measures. He acknowledges that the theoretical side has developed more slowly than applications, particularly applications that are supported by sponsoring organizations more satisfied with local insights than general models.     

High rates of paraquat-induced suicide in southern Trinidad.

The suicide rate in Trinidad and Tobago is much greater than that of its English-speaking Caribbean neighbors. Many of these suicides are paraquat induced. This research reviewed the deaths due to suicide in the area with the greatest agricultural activity in Trinidad for 1996 and identified, for further demographic and etiological investigation, cases in which paraquat was ingested as the agent of suicide. Of 48 cases of suicide for the year, 39 (81.3%) were due to paraquat poisoning. The incidence of paraquat-induced suicide was 8.0 per 100,000. Among the males, 47.8% were in the age group 25-34 (p < 0.001), and among the females 50.0% were in the 15-24 age group (p < 0.05). Family-of-origin disputes were the most frequently cited precipitant, followed by marital problems. Individuals of East Indian origin accounted for 89% of the suicide victims (p < 0.001). When compared with suicide by other methods in the country, these findings confirm that paraquat poisoning is a significant means of suicide in Trinidad and that young East Indian individuals are particularly vulnerable.     

Ensuring quality in online career mentoring

This article explores the issue of quality in online career mentoring. It builds on a previous evaluation of Brightside, an online mentoring system in the UK which is primarily aimed at supporting young people's transitions to further learning. The article notes that participants in Brightside's mentoring programmes reported satisfaction with their experiences, with many stating that it helped them to make decisions and to positively change their learning and career behaviours. However, the article argues that there are challenges in ensuring quality and consistency connected to both the voluntary nature of mentoring and the online mode. The article proposes a 10-point quality framework to support quality assurance, initial training and professional development for online mentors.
