Right up there: hemispatial and hand asymmetries of altitudinal pseudoneglect

Background

Pseudoneglect is a normal left sided spatial bias observed with attempted bisections of horizontal lines and a normal upward bias observed with attempted bisections of vertical lines. Horizontal pseudoneglect has been attributed to right hemispheric dominance for the allocation of attention. The goal of this study was to test the hypothesis that the upward bias in vertical line bisection may also relate to right hemispheric dominance for the allocation of attention and/or action-intention.

Methods

Twenty right handed healthy adults were asked to bisect vertical lines presented in the midsagittal plane (center space) and in sagittal planes to the left and right of the midsagittal plane (left and right hemispace) when using a pen held in either the right or left hand.

Results

Vertical line bisections were biased upward in all three sagittal planes and higher in left than right hemispace. However, bisections made with the left hand were lower than those made with the right hand.

Discussion

Whereas these results suggest a left hemispace-right hemispheric visuospatial attentional upward bias and a relative left hemispheric-right hand upward action-intentional bias, further studies are needed to document this intentional versus attentional bias and to understand the brain mechanisms that produce these biases.     

A Pilot Randomized Trial of Community-Based Parent Training for Immigrant Latina Mothers

This paper reports on the development and piloting of the Madres a Madres (Mothers to Mothers) program, a new, community-based parent training program designed for immigrant Latina mothers and their children. Promotoras, or female community health workers of Latina background, delivered the program in a home visitation format. A total of 194 mothers and 194 focal children (87 male, 107 female) ages 7–12 were randomized to the intervention (113 mother–child dyads) or wait-list control condition (81 mother–child dyads) over the study period. Outcomes of interest were mother-reported parenting skills, broad family functioning, and child externalizing and internalizing behaviors. Data collection occurred at pretest, 3-month posttest, and 9-month follow-up periods. Multilevel growth models revealed increases in intervention mothers’ reported parenting skills, family support, and family organization, and reductions in child internalizing behavior from pretest to follow-up, relative to the control condition. Outcomes did not vary by focal child age, gender, nativity status, or mother acculturative status (years in the United States). Findings are discussed in the context of future directions for research on the Madres a Madres program and on the implementation and dissemination of empirically-supported parent training practices to culturally diverse families.     

Ideology and the problem of knowledge

The purpose of this article is to deal with certain problems stemming from the concept of Ideology. It begins by describing some aspects of the ‘ordinary notion’ of ideology, and goes on to criticize a standard (the economic determinist) interpretation of Marx's position. It then deals with a problem traditionally connected with ideology, the so‐called Problem of Knowledge, and argues that it is a pseudo‐problem. The article concludes by proposing a conception of ideology as synecdoche which, it is claimed, helps us to avoid some of the mistakes imbedded in the Problem of Knowledge and the economic determinist interpretation of Marxism.     

The Construct Validity of the Strengths and Difficulties Questionnaire for Aboriginal Children Living in Urban New South Wales,Australia

The current study explores the construct validity of the standard Strengths and Difficulties Questionnaire (SDQ) for Aboriginal children living in urban communities in New South Wales, Australia. Parent report SDQ data from the first 717 Aboriginal children aged 4–17 years who participated in the baseline survey of the Study of Environment on Aboriginal Resilience and Child Health were analysed. The overall construct validity of the SDQ in our sample was acceptable but not “good.” The internal consistency reliability was excellent overall and good for all subscales with the exception of peer problems, a concept that may have a different significance for urban Aboriginal parents. Removing the peer relationships subscale, however, did not improve the fit of the model. The convergent validity of the SDQ was good. The prosocial behaviours scale and both the peer and conduct problems scales were highly correlated suggesting Aboriginal parents conceptualise these differently and that prosocial behaviours may be considered a key indicator of well‐being for Aboriginal children. Overall, the SDQ is a promising tool for urban Aboriginal children in New South Wales. Those working with Aboriginal young people should focus on the SDQ total difficulties score and limit their reliance on the peer relationships subscale.     

An explanation for the low-temperature H evolution peak in hydrogenated amorphous silicon films deposited 'on the edge of crystallinity'

The puzzling existence of a sharp low-temperature (T = 400°C) H evolution peak in compact hydrogenated amorphous silicon (a-Si : H) films deposited 'on the edge of crystallinity' is examined. From infrared absorption and X-ray diffraction (XRD) measurements, we show that none of the standard methods used to explain the existence of this peak in a-Si : H materials is applicable to the present films. From the Si-H wag-mode peak frequency, we postulate the existence of very small Si crystallites contained within the amorphous matrix. While the crystallite volume fraction is too small to be detected by XRD in the as-grown films, crystallization is observed for this material at anneal temperatures as low as 500°C. It is proposed that these crystallites catalyse the crystallization of the remainder of the amorphous matrix upon moderate annealing, enabling H surface desorption and H₂ out-diffusion to the sample surface along newly formed grain boundaries at low anneal temperatures.     

The Lazarus Project: a longitudinal study of spiritual transformation among substance abusers

This is a longitudinal study of spiritual transformation at the Lazarus Project (LP), a 12-month Pentecostal-Charismatic residency program for substance abuse. In 2006, we began administering to residents an assessment protocol consisting of psychological (depression, self-esteem, psychopathology, Big 5 personality markers) and religiosity (fundamentalism, religious orientation, spiritual well-being, mysticism) measures. Assessments were at: (T1) induction; (T2) six months; (T3) graduation; and (T4) one-year post-graduation. We also assessed a membership group from the sponsoring church using the same protocol. Analyses found that general change in graduate scores occurred from T1 to T2 and persisted to T3 and T4. Comparative analyses found that LP graduate score patterns generally agreed with those of LP dropouts at T1, but diverged at T2, becoming more similar to score patterns of church members. Using all measures, a regression analysis found that the personality marker of (less) openness was the most powerful predictor of resident dropout. The preliminary findings suggest that, among chronic substance abusers, the LP helps to facilitate conversion as a form of spiritual transformation that persists at least one-year post-graduation.     

Positive work experiences and life satisfaction: the moderating role of gender

This study investigated the effects of work engagement and psychological meaningfulness on life satisfaction taking into account the moderating effect of gender. A cross-sectional research design was used to capture data on satisfaction with life, work engagement and psychological meaningfulness. The sample consisted of 796 employees from various companies in South Africa (women?=?65.9%; aged between 18 and 67). The results showed work engagement and psychological meaningfulness to significantly predict life satisfaction. A significant interaction effect for gender was found on the relationships between work engagement on life satisfaction and psychological meaningfulness on work engagement respectively. The results indicated that men showed a higher level of life satisfaction when work engagement was high. Women showed lower levels of life satisfaction the more they engage in their work. Women further experienced a higher level of work engagement compared to men; however, the relationship between psychological meaningfulness and work engagement was stronger for men. The more psychological meaningfulness men experience, the more they will engage-unlike women, who tend to experience work engagement irrespective of psychological meaningfulness.     

Images of Nuclear Activists in Four Countries

Students at colleges or universities in North Carolina (United States), Bath (England), Munich (West Germany) and Selangor (Malaysia) were asked to evaluate a nuclear activist who had engaged in one of three forms of protest against nuclear weapons, ranging from conventional to nonconventional. The age and gender of the activist was also varied; the activist was either male or female and either 22 years old or 72 years old. The overall images of the various activists were positive in all four locations, though the nature of the positive image differed in the four studies. In all four studies, the nature of the activism was of much greater importance than either the age or gender of the activist; the activist who engaged in the most nonconventional form of protest (resulting in his or her arrest) received the least positive ratings. Women evaluated the activists more positively than did men.     

Debiasing of Pessimistic Judgments Associated with Anxiety

This study tested the Consider-An-Alternative debiasing procedure and its ability to reduce pessimistic judgmental predictions associated with anxiety. Study participants were randomly assigned to either a control group or a debiasing group and were asked to rate the likelihood of hypothetical events. Level of trait anxiety was assessed to assign participants to a normal and a highly anxious group. The results showed that the debiasing procedure was effective in the reduction of pessimistic judgmental predictions for participants with both high and normal levels of trait anxiety. Specifically, the generation of alternative positive information significantly reduced pessimistic predictions of future events. The results were discussed in terms of availability of information in memory and cognitive biases.     

Mentalizing strategies for navigating the social world in adolescence

Mentalizing—the ability to represent or infer the mental states of others—continues to develop into and throughout adolescence. Increased mentalizing sophistication during adolescence is thought to support the navigation of increasingly complex social relationships and contexts. However, developmental science has yet to aggregate the seemingly disparate findings from research relating mentalizing to functional outcomes, such as internalizing mental health concerns, into clear and comprehensive theories that explain individual variability during adolescence. In this review, we describe approaches that have been used to measure mentalizing during adolescence and propose a methodological framework to measure mentalizing as a multi-dimensional process that continues to develop as a response to the environment during adolescence.
