The smoking patterns of women in their forties: their relationship to later osteoporosis

Osteoporosis is prevalent among women 50 years of age and older and accounts for numerous fractures and the related deaths of many sufferers. In this study, 22.4% of the women reported having osteoporosis. Smoking contributes substantially to osteoporotic fractures. This study assessed how different trajectories of women's smoking, covering the ages 40 to 48 years, relate to osteoporosis at age 65. Trajectory analysis of tobacco use data reveals smoking patterns which may have differing relationships to osteoporosis. Logistic regression analyses revealed the varying relationships of different smoking patterns to osteoporosis. As hypothesized, the chronic/heavy smokers were significantly more likely than the non-smokers to report having osteoporosis. Quitters and moderate smokers did not differ significantly from non-smokers on the osteoporosis measure. Chronic/heavy smokers should not be the only focus of public health efforts to reduce smoking and the associated risks of osteoporosis. The findings also highlight the efficacy of women smokers quitting in their 40s in order to reduce their likelihood of contracting osteoporosis.     

Leniency for out‐group offenders

The present research investigates leniency for out‐group offenders and differentiates it from the black sheep effect. The authors assume that leniency for out‐group offenders can be used by in‐group members to protect their group's image by displaying that they are not prejudiced. Thus, leniency should disappear when in‐group members have otherwise shown that they are not prejudiced (i.e., moral credentials). In two experiments, offenders' group membership and participants' opportunity to establish moral credentials were manipulated. Results showed that out‐group offenders received the lowest punishment severity ratings (Studies 1 and 2). However, this leniency effect vanished when participants had established moral credentials by either endorsing the participation of out‐group members in lobby groups (Study 1) or writing about a positive experience with an out‐group member (Study 2). These findings suggest that lenient punishments for out‐group offenders may sometimes reflect a relatively easy strategy to display the in‐group as being unprejudiced.

Differential Susceptibility Effects: The Interaction of Negative Emotionality and Sibling Relationship Quality on Childhood Internalizing Problems and Social Skills

Whereas socialization influences in early childhood have been linked to children's emerging internalizing problems and prosocial behavior, relatively few studies have examined how NE might moderate such associations in both advantageous and maladaptive ways. Furthermore, more research is needed to evaluate the impact of sibling relationships as an influential socialization influence on these child outcomes. In the current study we examined how NE might differentially moderate the associations between quality of relationships with siblings and both internalizing problems and social skills at school entry. NE moderated the effects of positive and destructive sibling relationship quality on child internalizing problems. Specifically, for boys high on NE, more positive sibling relationship quality predicted fewer internalizing problems, but more destructive sibling conflict predicted more internalizing problems. NE also moderated the effects of destructive sibling conflict on child social skills. For boys high on NE, destructive sibling conflict predicted fewer social skills. Boys high on NE appear to show greater susceptibility to the effects of sibling socialization on child outcomes, relative to boys low on NE. The implications of these interactions are discussed with respect to differential susceptibility theory.     

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.
