The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach

Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

Post-retrieval disruption of a cocaine conditioned place preference by systemic and intrabasolateral amygdala β2- and α1-adrenergic antagonists

Previous work has demonstrated post-retrieval impairment in associative learning paradigms, including those mediated by drugs of abuse, using nonspecific β-adrenergic receptor (β-AR) antagonists. Remarkably little is known about the role of the specific β-AR subtypes, or other adrenergic receptors, in these effects. The current study examined the effects of β₁ and β₂, as well as α₁-adrenergic receptor antagonism following retrieval of a cocaine conditioned place preference (CPP). We found that rats administered the β₂ antagonist ICI 118,551 (8 mg/kg intraperitoneal [IP]) or the α₁ antagonist prazosin (1 mg/kg IP) following a drug-free test for CPP showed attenuated preference during a subsequent test, while the β₁ antagonist betaxolol (5 or 10 mg/kg IP) and a lower dose of prazosin (0.3 mg/kg IP) had no effect. Furthermore, post-test microinfusion of ICI 118,551 (6 nmol/side) or prazosin (0.5 nmol/side) into the basolateral amygdala (BLA) also impaired a subsequent preference. Systemic or intra-BLA ICI 118,551 or prazosin administered to rats in their home cages, in the absence of a preference test, had no effect on CPP 24 h later. ICI 118,551 also attenuated the FOS response in the BLA induced by the CPP test. These results are the first to demonstrate a role for α₁- and β₂-specific adrenergic mechanisms in post-retrieval memory processes. These systemic and site-specific injections, as well as the FOS immunohistochemical analyses, implicate the importance of specific noradrenergic signaling mechanisms within the BLA in post-retrieval plasticity.Substantial evidence indicates that information acquired during a learning event is initially plastic, at which time memory retention can be disrupted, but is strengthened by a time-dependent consolidation process (McGaugh 2000). Recent work has focused on retrieval-induced plasticity, a process by which changes in the retention of previously acquired information are possible. The notion of reconsolidation, one theoretical mechanism by which such changes may occur, suggests that a retrieved memory enters a labile state and is vulnerable to disruption (Sara 2000; Nader 2003). Although the theoretical mechanisms underlying reconsolidation remain unclear, the behavioral effects have been demonstrated across many different learning paradigms using a variety of pharmacological manipulations (for review, see Tronson and Taylor 2007; Diergaarde et al. 2008). Studies with aversive and appetitive preparations, including drug reward-mediated learning, have demonstrated that the noradrenergic system is important for these post-retrieval memory processes (Przybyslawski et al. 1999; Debiec and Ledoux 2004; Bernardi et al. 2006; Diergaarde et al. 2006; Robinson and Franklin 2007; Abrari et al. 2008; Fricks-Gleason and Marshall 2008; Milton et al. 2008). For example, using an animal model of cocaine-conditioned behaviors, Bernardi et al. (2006) demonstrated that systemic post-retrieval administration of propranolol impaired a subsequent conditioned place preference (CPP), suggesting that β-adrenergic receptors (β-ARs) play an important role in processes occurring following drug memory retrieval.However, most of what is known about the noradrenergic system in the memory processes that follow cued reminder trials comes from studies that use nonspecific β-AR antagonists, such as propranolol. As a consequence, several issues regarding ARs and post-retrieval memory processes remain unresolved. First, because propranolol has affinity for both β₁- and β₂-AR subtypes, it is unclear which subtype mediates these effects. To date, no studies have examined reconsolidation-like impairments using subtype-specific β-AR antagonists, which is important because more specific medications may be equally efficacious with less adverse effects. Second, no studies to date have examined α-ARs regarding a potential role in reconsolidation-like effects. α-ARs—specifically α₁-ARs—have a demonstrated role in memory consolidation (Ferry et al. 1999a,b) and may also mediate post-retrieval processes. Third, although the BLA has had a demonstrated role in reconsolidation-like effects in numerous studies, the behavioral conditions during retrieval of drug-associated memories leading to gene expression within the basolateral amygdala (BLA) have not clearly been defined. Specifically, in the CPP paradigm used here, it is unclear whether exposure to a cocaine cue alone will induce gene expression or whether a preference for the drug-associated environment needs to be expressed for BLA involvement (Franklin and Druhan 2000; Miller and Marshall 2005).Understanding the role of specific adrenergic receptors in mediating post-retrieval memory processes is particularly important in drug-induced CPP. In humans, drug-associated stimuli can facilitate drug use (Gawin 1991; See 2005) or precipitate relapse following abstinence (O''Brien et al. 1992). Thus, pharmacotherapies targeting these memory processes would benefit from a clearer understanding of the specific receptors that mediate behavioral effects (Taylor et al. 2009).Here, we first examined the effects of systemic post-test β₁-, β₂-, and α₁-AR antagonism on cocaine CPP. We then focused on the BLA due to its involvement in reconsolidation-like effects in drug learning paradigms (e.g., Lee et al. 2005), employing microinfusions of AR antagonists and measuring FOS immunoreactivity (FOS-IR) to examine the BLA as a potential site of AR-mediated impairments.     

Seeking the perfect balance: Perfectionism and work–family conflict

This study considers the relationship between perfectionism and perceptions of work–family conflict. A situational component to perfectionism was found, with higher standards and a higher perceived discrepancy between standards and performance at home versus at work. Findings suggest perfectionism predicts work–family conflict, beyond the effects of the Big Five, trait affectivity and achievement. Further, findings indicate those with adaptive perfectionism (AP; work and home) tend to have lower strain and time‐based family interfering with work and lower behaviour‐based work interfering with family, compared with maladaptive perfectionists (home) and non‐perfectionists (work and home). Gender differences were found and considered in a more exploratory manner.     

Mediational effects of sensation seeking on the age and financial risk-taking relationship

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship.     

The development of academic competence among adolescents who bully and who are bullied

Using data from the first three waves (Grades 5, 6, and 7) of the 4-H Study of Positive Youth Development, this study assessed if being a bully or being a victim accounts for an adolescent's academic competence, if selected contextual and individual variables impact an adolescent's academic competence, and if such impact differs in relation to an adolescent's bullying status. The results of random coefficient hierarchical regression analyses indicated that being a bully predicted lower grades across time, and that being a bully was more detrimental for girls than for boys. Being a bully and being a victim negatively predicted self-perceived academic competence, but these predictive effects did not change over time or differ by sex. Teacher support positively predicted grades and greater parent support and teacher support independently predicted higher self-perceive academic competence. Greater educational expectations and school engagement independently predicted higher self-reported grades, while these two predictors positively interacted in explaining self-perceived academic competence. Unexpectedly, peer support negatively predicted self-reported grades for victims, and negatively predicted self-perceived academic competence for bullies. We discuss the importance of addressing the issue of academic competence in bullying interventions, as well as the utility of capitalizing on developmental assets in promoting academic competence among adolescents who bully and who are bullied.     

How to get “kissably close”: Examining how advertisers appeal to consumers’ sexual needs and desires

This paper explores the nature of sexual appelas—sex-related promises or benefits—in mainstream advertising by describing types of sex appeals and findings from a sex-benefit content analysis. Overall, our findings reveal that sex is used to appeal to women and men, although a higher proportion of sexual ads appear in men’s (12%) compared to women’s magazines (6%). In addition, a variety of sex appeals are directed toward women (attractiveness, behavior, esteem), whereas most appeals directed toward men emphasize more and better sex. Last, male-only images are relatively absent in sexual ads compared to female-only (45%) and couples (47%) images. These findings, observations, and directions for future research are discussed.     

Development of beliefs about the origins and controllability of dreams.

In three studies the authors investigated the development of beliefs about dreaming. Study 1 assessed 3- to 5-year-old children's beliefs about the origins and controllability of dreams. Results revealed significant changes in children's beliefs about the roles of behavioral experiences and mental processes in the generation of dream content. Results also revealed that young children consider both dreams and imagination to be highly controllable. In Study 2, preschool-age children, elementary school-age children, and adults received either imagination or dream stories and were questioned about controllability. In Study 3, emotional valence of the dream content was varied. Results of Studies 2 and 3 revealed significant development in beliefs that dreams are not subject to conscious control. Beliefs in controllability were higher among females. Study 3 showed that the emotional content of a dream affects these claims.     

Developmental assessment, cultural context, gender, and schooling in Zambia

Multiple perspectives on the assessment of children's development at the school-community interface in rural areas of Zambia are discussed in the light of several empirical studies conducted between 1974 and 2005. A longitudinal trace study of a cohort of 46 young people born into a rural, Chewa community in Katete District found that girls' scores in early childhood on a battery of ecoculturally grounded cognitive tests correlated less well than they did for boys with two educational outcomes: number of grades of schooling completed, and adult literacy scores. Conversely, ratings of the children on indigenous conceptions of intelligence by adults familiar with the children in the context of their home village lives predicted the same outcomes better for girls than for boys. A separate, linked experiment compared the performance of 76 Katete school children with that of 84 school children in the capital city of Lusaka on the US standardized Draw-a-Person Test (DPT) and the Panga Munthu Test (PMT), an expanded version of one of the tests developed for the Zambian trace study. Analysis of the correlations among scores on these two tests, age, and teacher ratings suggests that aptitudes evident in the home and school domains are less well integrated for rural girls than for urban boys, and that for a low-income, rural population, the PMT taps the domain of home cognition better than school cognition, while the converse is true of the DPT. Implications for educational assessment in Zambia are discussed, and supportive documentation is cited from two ongoing programs of test development. The authors conclude that if educational testing is to support the process of enhancing educational equity across gender, family socioeconomic status, and residential location, its focus should be broadened to include other dimensions of psychological development such as multilingual and personal-social competencies.     

Who drives divergence? Identity signaling, outgroup dissimilarity, and the abandonment of cultural tastes

People often diverge from members of other social groups: They select cultural tastes (e.g., possessions, attitudes, or behaviors) that distinguish them from outsiders and abandon tastes when outsiders adopt them. But while divergence is pervasive, most research on the propagation of culture is based on conformity. Consequently, it is less useful in explaining why people might abandon tastes when others adopt them. The 7 studies described in this article showed that people diverge to avoid signaling undesired identities. A field study, for example, found that undergraduates stopped wearing a particular wristband when members of the "geeky" academically focused dormitory next door started wearing them. Consistent with an identity-signaling perspective, the studies further showed that people often diverge from dissimilar outgroups to avoid the costs of misidentification. Implications for social influence, identity signaling, and the popularity and diffusion of culture are discussed.     

Relational‐Cultural Theory: A Framework for Bridging Relational,Multicultural, and Social Justice Competencies

Relational‐cultural theory (RCT) theorists advocate expanding the multicultural/social justice counseling competencies beyond the domains of self‐awareness, cultural knowledge, and culturally responsive helping skills. This article provides an overview of RCT and discusses how creating and participating in growth‐fostering relationships are essential dimensions of human development and psychological well‐being. Implications of this theoretical model for counseling practice are also addressed.
