Exploitative male mating strategies: Personality, mating orientation, and relationship status

Previous research suggests men are sexually attracted to women displaying cues to sexual exploitability. During human evolutionary history, men’s agreeableness, orientation towards casual sex, and relationship status may have been recurrently associated with greater net benefits of pursuing a sexually exploitative strategy. We hypothesized these three individual differences would predict men’s perceptions of women’s sexual exploitability. Seventy-two men viewed photographs of women and rated their sexual exploitability. Men’s agreeableness, sociosexual orientation, and current relationship status interacted to predict their perceptions of women’s sexual exploitability; among unmated men, the combination of low agreeableness and an orientation toward uncommitted sex was associated with higher perceptions of women’s sexual exploitability. This suggests mechanisms motivating sexually exploitative strategies may depend on an interaction between personality characteristics and situational variables.     

Thoughts on Thinking: Engaging Novice Music Students in Metacognition

Achieving expertise in any area requires extensive practice and engagement with the subject one desires to master. As not all practice yields good progress, methods must be found that lead learners to practice effectively. Many experts employ highly tailored practice involving metacognitive processes, but novices rarely engage in frequent and explicit metacognitive strategies during practice. As a result, novice progress may be impeded through repetition of systematic errors and ineffective techniques. Our study provides evidence of the effectiveness of teaching metacognition to novice music students through weekly lessons. Thirty‐five adolescent students of six instructors were randomly assigned to metacognitive focus or existing practice teaching conditions. Students receiving metacognitive teaching achieved higher performance ratings when compared with students receiving control instruction, even though practice time did not vary between groups. These results suggest that having students explicitly verbalize and reflect on their learning process produces more efficient practice and greater end performance.

Impact of Depression and Childhood Trauma in Mothers Receiving Home Visitation

Research has documented the deleterious effects of maternal depression and childhood trauma on parenting and child development. There are high rates of both depression and childhood trauma in new mothers participating in home visitation programs, a prevention approach designed to optimize mother and child outcomes. Little is known about the impacts of maternal depression and childhood trauma on parenting in the context of home visitation. This study contrasted depressed and non-depressed mothers enrolled in the first year of a home visitation program on parenting stress, quality of home environment, social network, and psychiatric symptoms. Mothers were young, low income, and predominantly unmarried. Results indicated that depressed mothers displayed impairments in parenting, smaller and less robust social networks, and increased psychiatric symptoms relative to their non-depressed counterparts. Path analyses for the full sample revealed a path linking childhood trauma, depression, and parenting stress. Path analyses by group revealed several differential relationships between dimensions of social network and parenting. Number of embedded networks, namely the number of different domains in which the mother is actively interacting with others, was associated with lowered parenting stress among non-depressed mothers and increased parenting stress in their depressed counterparts with childhood trauma histories. In depressed mothers, social network size was associated with lower levels of parenting stress but decreased quality of the home environment, whereas number of embedded networks was positively related to quality of the home environment. Implications of findings for home visitation programs are discussed.     

The Association of Externalizing Behavior and Parent–Child Relationships: An Intergenerational Study

We investigated the influence of the child’s behavior on the quality of the mutual parent–child attachment relationships across three generations. We did so using a prospective longitudinal study which spanned 20 years from adolescence through adulthood. Study participants completed in-class questionnaires as students in the East Harlem area of New York City at the first wave and provided follow-up data at 4 additional points in time. 390 participants were included in these analyses; 59% female, 45% African American, and 55% Puerto Rican. Using structural equation modeling, we determined that externalizing behavior in the child was negatively related to the mutual parent–child attachment relationship for two generations of children. We also found continuity in externalizing behavior for the participant over time and from the participant to his/her child. Additionally, we found continuity in the quality of the mutual attachment relationship from the participant’s relationship with his/her parents to the participant’s relationship with his/her child. Finally, the mutual attachment relationship of the participant with his/her parents had a negative association with the participant’s externalizing behavior in adulthood. Based on these results, we propose that family interventions should focus on the role of the child’s externalizing behavior in the context of the parent–child attachment relationship. Furthermore, we suggest that prevention programs should address externalizing behavior as early as possible, as the effects of externalizing behavior in adolescence can persist into adulthood and extend to the next generation.     

Serotonin transporter knockout rats show improved strategy set-shifting and reduced latent inhibition

Behavioral flexibility is a cognitive process depending on prefrontal areas allowing adaptive responses to environmental changes. Serotonin transporter knockout (5-HTT(-/-)) rodents show improved reversal learning in addition to orbitofrontal cortex changes. Another form of behavioral flexibility, extradimensional strategy set-shifting (EDSS), heavily depends on the medial prefrontal cortex. This region shows functional changes in 5-HTT(-/-) rodents as well. Here we subjected 5-HTT(-/-) rats and their wild-type counterparts to an EDSS paradigm and a supplementary latent inhibition task. Results indicate that 5-HTT(-/-) rats also show improved EDSS, and indicate that reduced latent inhibition may contribute as an underlying mechanism.     

Pathways to children's externalizing behavior: a three-generation study

In this study, based on Family Interactional Theory (FIT), the authors tested a longitudinal model of the intergenerational effects of the grandmothers' parent-child relationships and the grandparents' smoking on the grandchildren's externalizing behavior via parents' psychological symptoms, tobacco use, and child rearing. Using Mplus, the authors obtained a structural equation model that demonstrated generational associations from grandmothers (G1) to parents (G2) to their oldest children (G3) and thus was in accord with FIT. They identified a pathway from the grandmothers' parenting to the grandchildren's externalizing behavior via the parents' psychological symptoms, their smoking, and their child rearing. Parents' psychological symptoms in adolescence were associated with their tobacco use in their late twenties, controlling for the continuity of their psychological symptoms and their tobacco use. This 3-generational model adds to the literature on parent-child relationships (G1), smoking from adolescence to early adulthood (G2), and externalizing behavior in the G3 child.     

Cross-sectional and longitudinal predictors of well-being: invariance across 25 years

This study addressed: (a) whether any changes in well-being over time could be attributed to participants’ aging or to economic or historical events; (b) whether predictors (e.g. age, religiosity, and financial status) were similarly associated with well-being in cohorts of college seniors assessed at different times; and (c) whether predictors of well-being were similar for the same cohort over a 25-year time span. Using three cohorts of emerging adults (1982, n?=?189; 2007, n?=?188; and 2010, n?=?79) and a subsample of the 1982 cohort followed across 25?years (n?=?83), the findings indicated that well-being declined over time, possibly due to historical influences rather than changes associated with aging. Well-being was similarly predicted by religiosity, relationship status, and financial status across cohorts. Longitudinal analyses indicated that earlier religiosity was inversely associated with later financial status and later financial status was associated with higher well-being.     

Genetic Counselors’ Views and Experiences with the Clinical Integration of Genome Sequencing

In recent years, new sequencing technologies known as next generation sequencing (NGS) have provided scientists the ability to rapidly sequence all known coding as well as non-coding sequences in the human genome. As the two emerging approaches, whole exome (WES) and whole genome (WGS) sequencing, have started to be integrated in the clinical arena, we sought to survey health care professionals who are likely to be involved in the implementation process now and/or in the future (e.g., genetic counselors, geneticists and nurse practitioners). Two hundred twenty-one genetic counselors— one third of whom currently offer WES/WGS—participated in an anonymous online survey. The aims of the survey were first, to identify barriers to the implementation of WES/WGS, as perceived by survey participants; second, to provide the first systematic report of current practices regarding the integration of WES/WGS in clinic and/or research across the US and Canada and to illuminate the roles and challenges of genetic counselors participating in this process; and third to evaluate the impact of WES/WGS on patient care. Our results showed that genetic counseling practices with respect to WES/WGS are consistent with the criteria set forth in the ACMG 2012 policy statement, which highlights indications for testing, reporting, and pre/post test considerations. Our respondents described challenges related to offering WES/WGS, which included billing issues, the duration and content of the consent process, result interpretation and disclosure of incidental findings and variants of unknown significance. In addition, respondents indicated that specialty area (i.e., prenatal and cancer), lack of clinical utility of WES/WGS and concerns about interpretation of test results were factors that prevented them from offering this technology to patients. Finally, study participants identified the aspects of their professional training which have been most beneficial in aiding with the integration of WES/WGS into the clinical setting (molecular/clinical genetics, counseling and bioethics) and suggested that counseling aids (to assist them when explaining aspects of these tests to patients) and webinars focused on WES/WGS (for genetic counselors and other health care professionals) would be useful educational tools. Future research should permit us to further enhance our knowledge of pitfalls and benefits associated with the introduction of these powerful technologies in patient care and to further explore the roles and opportunities for genetic counselors in this rapidly evolving field.     

A role for recency of response conflict in producing the bivalency effect

The bivalency effect is a block-wise response slowing that is observed during task-switching when rare stimuli that cue two tasks (bivalent stimuli) are encountered. This adjustment in response style affects all trials that follow bivalent stimuli, including those trials that do not share any features with bivalent stimuli. However, the specific stimulus and response properties that trigger the bivalency effect are not well understood. In typical bivalency effect experiments, bivalent stimuli can be congruent or incongruent with respect to the response afforded by the irrelevant stimulus feature, and this distinction has never been examined. In the present study, we show that cognitive load defined by the response incongruence on bivalent trials plays a critical role in producing the subsequent response slowing observed in the bivalency effect, as well as maintaining the magnitude of the bivalency effect across practice. We propose that the bivalency effect reflects a process involved in predicting future cognitive load based on recent cognitive load experience. This is in line with a recent proposal for a role of the ACC in monitoring ongoing changes in the environment to optimize future performance (Sheth et al., in Nature 488:218–221, 2012).
