Sleep Symptoms as a Partial Mediator Between Combat Stressors and Other Mental Health Symptoms in Iraq War Veterans

Sleep symptoms are a prominent feature of mental health disorders like PTSD and depression. However, it is unknown whether sleep symptoms mediate the relationship between combat stress and these disorders. We examined the mediating role of sleep symptoms on the relationship between combat stress and PTSD; and the relationship between combat stress and depression using data from 576 Army veterans of the Iraq War surveyed in 2004. Correlational analyses revealed that when insomnia was included in the model, the correlation between combat stressors and other depression symptoms decreased by 65%; and when nightmares were included in the model, the correlation between combat stressors and other PTSD symptoms decreased by 69%. We replicated these analyses using individual items assessing PTSD and depression and found that the insomnia and nightmare items had the largest and second largest mediation effect between combat stressors and PTSD and depression symptoms. Our result support the theory that sleep symptoms contribute to the development and/or maintenance of other mental health symptoms and that early treatment of sleep symptoms may mitigate the other mental health consequences of combat stress.     

Contribution of parents' adult attachment and separation attitudes to parent‐adolescent conflict resolution

This study examined the contribution to parent‐adolescent conflict resolution of parental adult attachment styles and attitudes toward adolescent separation. Questionnaires were completed by 295 couples with early to late adolescent children. Structural equation models were used to test self and partner influences on conflict resolution for three attachment orientations: confidence (model A), anxiety (model B) and avoidance (model C). Model A showed self influences between parents' confidence orientation and negotiation and also via positive attitudes towards separation. Also, the fathers' use of negotiation was facilitated by the mothers' confidence orientation and vice versa, indicating partner influences as well. Model B showed self influences between parents' anxiety orientation and the use of dominance and withdrawal and also via negative attitudes towards separation. Model C showed self influences between parents' avoidance orientation and dominance and withdrawal, and a partner influence between fathers' avoidance and mothers' use of dominance. The results indicated that the parents' adult attachment system and the parenting system were related in the area of conflict resolution, and that self influences were stronger than partner influences.     

The Catholic Church,moral doctrine,and HIV prevention in Recife,Brazil: Negotiating the contradictions between religious belief and the realities of everyday life

Religious beliefs have had a key role in shaping local responses to HIV and AIDS. As the world's largest Catholic country, Brazil is no exception. Yet little research has been conducted to document how religious doctrine is enacted in practice among its lay leaders and followers. In this article, we present ethnographic research from Recife, Brazil, conducted to understand the way in which religious doctrines are interpreted at a local level. Contextualised within the sociology of contemporary Brazilian Catholicism, we draw on interviews with clergy members, lay leaders, and parishioners to discuss how the Catholic Church's vision of sexuality translates into everyday lives of its followers. We explore the disjuncture between the Catholic ideals of fidelity and delaying sex until marriage with the everyday reality of the Church's followers, highlighting the role that gender plays in defining sexual roles and expectations. We conclude by posing questions for future research and HIV prevention strategies considering the formal institutional response of the Brazilian Catholic Church to AIDS on the one hand, and the social and cultural contexts in which Catholics live their daily lives on the other.     

Argentines’ collective memories of the military Junta of 1976: differences and similarities across generations and ideology

Although memories about a nation's past usually are semantic in nature, a distinction needs to be made between lived and distant semantic collective memories. The former refers to memories of community-relevant events occurring during the lifetime of the rememberer, whereas the latter to memories of distant events. Does the content of lived and distant semantic collective memories differ? Employing both free and cued recall, we examined the memories of younger and older Argentines of the Military Junta of 1976. We also examined the effects of political ideology. Content analysis indicated that (1) lived semantic collective memories were more likely to contain personal recollections than distant semantic collective memories, even though those with distant semantic collective memories could have incorporated memories of the parent's personal experience in their recollections, (2) lived semantic collective memories contained more causal statements, and (3) those on the Right with distant semantic collective memories were more likely to claim that they “Don't know” or offer positive accounts of the Junta, suggesting a need to “defend” the reputation of those on the Right. The results are discussed in terms of the goals and plans different generations might have when recollecting their nation's past.     

Tracking the emergence of memories: A category-learning paradigm to explore schema-driven recognition

Previous research has shown that prior knowledge structures or schemas affect recognition memory. However, since the acquisition of schemas occurs over prolonged periods of time, few paradigms allow the direct manipulation of schema acquisition to study their effect on memory performance. Recently, a number of parallelisms in recognition memory between studies involving schemas and studies involving category learning have been identified. The current paper capitalizes on these findings and offers a novel experimental paradigm that allows manipulation of category learning between individuals to study the effects of schema acquisition on recognition. First, participants learn to categorize computer-generated items whose category-inclusion criteria differ between participants. Next, participants study items that belong to either the learned category, the non-learned category, both, or neither. Finally, participants receive a recognition test that includes old and new items, either from the learned, the non-learned, or neither category. Using variations on this paradigm, four experiments were conducted. The results from the first three studies suggest that learning a category increases hit rates for old category-consistent items and false alarm rates for new category-consistent lures. Absent the category learning, no such effects are evident, even when participants are exposed to the same learning trials as those who learned the categories. The results from the fourth experiment suggest that, at least for false alarm rates, the effects of category learning are not solely attributable to frequency of occurrence of category-consistent items during learning. Implications for recognition memory as well as advantages of the proposed paradigm are discussed.     

THE MAGIC OF PLAY: LOW‐INCOME MOTHERS’ AND FATHERS’ PLAYFULNESS AND CHILDREN'S EMOTION REGULATION AND VOCABULARY SKILLS

Using data from a diverse sample of low‐income families who participated in the Early Head Start Research Evaluation Project (n = 73), we explored the association between mothers’ and fathers’ playfulness with toddlers, toddler's affect during play, and children's language and emotion regulation at prekindergarten. There were two main findings. First, fathers’ playfulness in toddlerhood was associated with children's vocabulary skills in prekindergarten whereas mothers’ playfulness was related to children's emotion regulation. Cross‐parental effects were found only for mothers. The association between mothers’ playfulness and children's vocabulary and emotion regulation was strengthened when fathers engaged in more pretend play and when children were affectively positive during the play. These findings show that playfulness is an important source of variation in the vocabulary and emotion regulation of children growing up in low‐income families. They also point to domain‐specific ways that mothers and fathers promote children's regulatory and vocabulary skills, and highlight the importance of children's positive engagement in play.     

Exploring Feminist Women's Body Consciousness

In a qualitative investigation of young feminists' experience of body consciousness, 25 feminist women each participated in one of 6 focus groups examining the ways they experienced body image and negotiated cultural messages about women's appearance. Participants described their experience with objectification and its impact on their body image, sense of self, and relationships with other women. Although feminism provided an alternative way to understand cultural messages and reframe negative thoughts, this understanding did not necessarily affect aesthetic reactions. Participants experienced conflict between their feminist beliefs and their feelings about beauty ideals and their own appearance. This conflict is interpreted in terms of a mere exposure effect and existing gender/power relations. Suggestions of ways feminist psychologists can support young women's strategies for resisting negative cultural messages are provided.     

Culture and the behavioural manifestations of traits: an application of the Act Frequency Approach

The behavioural manifestations of Big Five traits were compared across cultures using the Act Frequency Approach. American (n = 176) and Filipino (n = 195) students completed a Big Five measure and act frequency ratings for behaviours performed during the past month. Acts for specific traits cohered to an equivalent degree across cultures. In both cultures, the structure of act composites resembled the Big Five and the strength of trait‐behaviour relationships was very similar. Many acts were multidimensional and analyses revealed cultural commonalities and differences in the relevance and prevalence of acts for the Big Five traits. The results were more consistent with trait than cultural psychology perspectives, because traits predicted behaviour equally well, on average, in the two cultures.

Overt naming fMRI pre- and post-TMS: Two nonfluent aphasia patients, with and without improved naming post-TMS

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia.     

THE EVOLVING MANAGER STEREOTYPE: THE EFFECTS OF INDUSTRY GENDER TYPING ON PERFORMANCE EXPECTATIONS FOR LEADERS AND THEIR TEAMS

This study examined how external evaluators' assessments of a management team and its leader are impacted by congruence between the leader's gender and the gender typing of the industry in which the team works. We experimentally tested our theory using industries that are either male typed or gender neutral, with teams led by male and female leaders. Results indicate that performance expectations for the team were more favorable when the leader's gender was congruent with the industry's gender typing, but expectations for the leader were not affected by gender congruence. These findings paradoxically suggest that evaluators form performance expectations for teams based upon individual characteristics of their leaders, even when these characteristics have no effect on the conscious assessments of the leaders themselves.
