Why do women underperform under stereotype threat? Evidence for the role of negative thinking

This study investigated the role of negative thinking as a potential mediator of performance deficits under stereotype threat. After being assigned to a stereotype-threat or a no-threat condition, 60 female participants were asked to complete a difficult math task. Using the thought-listing technique, women under stereotype threat reported a higher number of negative thoughts specifically related to the test and to mathematics compared with women in the no-threat condition. Moreover, women under stereotype threat also showed a sharp decrease in performance that (a) was most pronounced in the second half of the test and (b) was mediated by the increase in negative thinking.     

Na+,K(+)-ATPase activity is reduced in hippocampus of rats submitted to an experimental model of depression: effect of chronic lithium treatment and possible involvement in learning deficits

This study was undertaken to verify the effects of chronic stress and lithium treatments on the hippocampal Na+,K(+)-ATPase activity of rats, as well as to investigate the effects of stress interruption and post-stress lithium treatment on this enzyme activity and on spatial memory. Two experiments were carried out; in the first experiment, adult male Wistar rats were divided into two groups: control and submitted to a chronic variate stress paradigm, and subdivided into treated or not with LiCl. After 40 days of treatment, rats were killed, and Na+,K(+)-ATPase activity was determined. In the second experiment, rats were stressed during 40 days, and their performance was evaluated in the Water Maze task. The stressed group was then subdivided into four groups, with continued or interrupted stress treatment and treated or not with lithium for 30 additional days. After a second evaluation of performance in the Water Maze, rats were killed and Na+,K(+)-ATPase activity was also measured. Results showed an impairment in Na+,K(+)-ATPase activity and in Water Maze performance of chronically stressed rats, which were prevented by lithium treatment and reversed by lithium treatment and by stress interruption. These results suggest that the modulation of Na+,K(+)-ATPase activity may be one of the mechanisms of action of lithium in the treatment of mood disorders.     

A data-driven approach to neuropsychological features in isolated REM behaviour disorder: A latent class analysis

Recent evidence demonstrated that neuropsychological assessment may be considered a valid marker of neurodegeneration in idiopathic REM sleep behaviour disorder (iRBD). However, little is known about the possible neuropsychological heterogeneity within the iRBD population. This retrospective study aimed to identify and describe different neuropsychological phenotypes in iRBD patients by means of a data-driven approach using latent class analysis. A total of 289 iRBD patients underwent a neuropsychological assessment evaluating cognitive domains: global cognition, language, short- and long-term memory, executive functions and visuospatial abilities. The presence of mild cognitive impairment (MCI) was also assessed. Latent class analysis was carried out to identify iRBD subtypes according to neuropsychological scores. The most parsimonious model identified three latent classes. Groups were labelled as follows: Class 2 “severely impaired” (n = 83/289): mean pathological scores in different tests, a high percentage of MCI multiple-domain and impairment in all neuropsychological domains. Class 1 “moderately impaired” (n = 44/289): mean neuropsychological score within the normal value, a high percentage of MCI (high risk to phenoconversion) and great impairment in the visuospatial domain. Class 3 “slightly impaired” (n = 162/289): no deficit worthy of attention except for short- and long-term memory. Our results suggest three different clinical phenotypes within the iRBD population. These findings may be relevant in the future for predicting the clinical trajectories of phenoconversion in iRBD.     

Validation of the Duke Religion Index: DUREL (Portuguese Version)

The purpose of the current study was to examine the psychometric properties of the Portuguese version of the Duke Religion Index (PDUREL) in a community setting. PDUREL was translated and adapted for administration to 383 individuals from a population-based study of low-income community-dwelling adults. The PDUREL intrinsic subscale and total scores demonstrated high internal consistency (alphas ranging from 0.733 for the total scale score to 0.758 for the intrinsic subscale). Correlations among the DUREL subscales were also examined for evidence of discriminant validity. Correlations were ranging from 0.36 to 0.46, indicating significant overlap between the scales without marked redundancy. PDUREL is a reliable and valid scale. The availability of a comprehensive, but brief measure of religiousness can help to study the role of religiousness in health by researchers from countries that speak the Portuguese language.     

Childhood conduct problems are associated with increased partnership and parenting difficulties in adulthood

This paper uses data from a sample of 337 parents studied at age 30 to examine the linkages between childhood conduct problems assessed at ages 7–9 and later partnership and parenting outcomes. The key findings of this study were: 1) increasing levels of childhood conduct problems were associated with increased risk of partnership difficulties, including relationship ambiguity, inter-partner conflict/violence and lower levels of relationship satisfaction; 2) increasing levels of childhood conduct problems were associated with increased risk of parenting difficulties, including over-reactivity, lax and inconsistent discipline, child physical punishment and lower levels of parental warmth and sensitivity. These findings were consistent across both parent reports and interviewer ratings, and in nearly all cases remained after extensive adjustment for confounding and selection bias. Study findings add to the growing body of evidence documenting the adverse consequences of early conduct problems for later adult interpersonal relationships and parenting behaviors.     

Applying the Interactive Systems Framework to the Dissemination and Adoption of National and State Recommendations for Hypertension

The Centers for Disease Control and Prevention (CDC), Division for Heart Disease and Stroke Prevention (DHDSP), commissioned an Institute of Medicine (IOM) report to identify the highest priority action areas for CDC, state health departments, and other public health partners in their efforts to reduce and control hypertension. To assess the dissemination and adoption of the IOM report recommendations, DHDSP developed an evaluation based on the Interactive Systems Framework for Dissemination and Implementation (ISF). The evaluation incorporates data collection at critical points across 3 years. In this article, we focus on the ISF systems to describe the role of funded state partners and their relationship with CDC in implementing public health recommendations. We describe baseline results for three data collection activities: (1) key informant interviews, (2) a Web‐based survey, and (3) content analysis of state workplans to determine the degree of alignment with IOM recommendations. For example, currently 30 % of surveyed programs are implementing most (or all) of the recommendations in the IOM report, however 76 % intend to change hypertension program priorities based on the recommendations of the IOM report. Qualitative data suggest that there are several facilitators and barriers in implementing public health policy recommendations. DHDSP will use these baseline results to provide additional technical assistance and support to state health departments in their efforts to implement the IOM report's recommendations.

Logical Metonymy Resolution in a Words‐as‐Cues Framework: Evidence From Self‐Paced Reading and Probe Recognition

Logical metonymy resolution (begin a book → begin writing a book) has traditionally been explained either through complex lexical entries (qualia structures) or through the integration of the implicit event via post‐lexical access to world knowledge. We propose that recent work within the words‐as‐cues paradigm can provide a more dynamic model of logical metonymy, accounting for early and dynamic integration of complex event information depending on previous contextual cues (agent and patient). We first present a self‐paced reading experiment on German subordinate sentences, where metonymic sentences and their paraphrased version differ only in the presence or absence of the clause‐final target verb (Der Konditor begann die Glasur → Der Konditor begann, die Glasur spreading the icing). Longer reading times at the target verb position in a high‐typicality condition (baker + icing → spread ) suggest that we make use of knowledge activated by lexical cues to build expectations about events. The early and dynamic integration of event knowledge in metonymy interpretation is bolstered by further evidence from a second experiment using the probe recognition paradigm. Presenting covert events as probes following a high‐typicality or a low‐typicality metonymic sentence (Der Konditor begann die Glasur → SPREAD ), we obtain an analogous effect of typicality at 100 ms interstimulus interval.
