A Longitudinal Assessment of Executive Function Skills and Their Association with Math Performance

The present study was designed to examine both concurrent and predictive associations between scores on a measure of executive function (EF) skills, the Contingency Naming Test (CNT), during the early school-age years. A secondary aim of the study was to examine the association between EF skills and mathematics performance. We administered tests of mathematics ability, and the CNT, to 178 children at ages 6 to 7, 8 to 9, and 10 to 11 years. From the CNT we obtained measures of response fluency/efficiency, working memory, and inhibition. The results demonstrate main effects of age on all CNT measures of EF, as anticipated, and inconsistent main effects of gender or mathematics learning disability status. Rates of improvement in EF varied as a function of the working memory demands present during a given task. There were differences in concurrent and predictive correlations for different CNT performance measures. EF scores obtained during the first assessment were as strongly associated with each other as they were with EF scores obtained four years later, suggesting a moderately stable source of individual differences on cognitive performance. EF scores at age 6 to 7 years were associated with concurrent and later mathematics scores, and most of these correlations were stronger than the significant associations found between response fluency on a baseline task (with no working memory demand) and mathematics performance. These findings have implications for the stability of EF skills during the school-age years, and the role of EF in early and later elementary school mathematics performance.     

Uncertainty in ethical consumer choice: a conceptual model

The market place has seen significant growth in the demand for ‘ethical’ products and services. Yet, consumers often experience knowledge, evaluation and choice uncertainties in decision‐making processes, particularly in relation to products such as ethical clothing. The authors explore this pertinent form of consumer uncertainty through three qualitative studies of ethical consumers that examine their approaches to clothing consumption. In‐depth interviews and focus groups confirm uncertainty arises; the results also identify the causes and consequences of consumer uncertainty in this context. The causes of uncertainty pertain to issues surrounding complexity, ambiguity, conflict and credibility that give rise to uncertainties that result in delaying purchase decisions, compromising beliefs and negative emotions. This study contributes to literature by offering a holistic understanding of the challenges facing consumers when making ethical choices. Copyright © 2013 John Wiley & Sons, Ltd.     

Structure and organization of research efforts following the bombing of the murrah building

Abstract

In the days and weeks following the Oklahoma City bombing on April 19,1995, Oklahoma state authorities, university faculty and staff, and leading experts from across the nation formed a coalition to address issues of clinical service delivery, educational intervention, and research. This article focuses on the centralized approach applied to the administration of research endeavors. This centralization was designed to minimize revictimization of both survivors and affected families, enhance the quality of data collected, and facilitate cooperation between participating investigators. The resultant set of projects includes a variety of research methodologies and study populations and will serve to significantly enhance understanding of the mental health sequelae of such disasters.     

Understanding associations between negatively biased attention and depression and social anxiety: positively biased attention is key

ABSTRACT

Background and objectives: Although research supports the premise that depressed and socially anxious individuals direct attention preferentially toward negative emotional cues, little is known about how attention to positive emotional cues might modulate this negative attention bias risk process. The purpose of this study was to determine if associations between attention biases to sad and angry faces and depression and social anxiety symptoms, respectively, would be strongest in individuals who also show biased attention away from happy faces.

Methods: Young adults (N?=?151; 79% female; M?=?19.63 years) completed self-report measures of depression and social anxiety symptoms and a dot probe task to assess attention biases to happy, sad, and angry facial expressions.

Results: Attention bias to happy faces moderated associations between attention to negatively valenced faces and psychopathology symptoms. However, attention bias toward sad faces was positively and significantly related to depression symptoms only for individuals who also selectively attended toward happy faces. Similarly, attention bias toward angry faces was positively and significantly associated with social anxiety symptoms only for individuals who also selectively attended toward happy faces.

Conclusions: These findings suggest that individuals with high levels of depression or social anxiety symptoms attend preferentially to emotional stimuli across valences.     

The cortisol awakening response in caregivers of schizophrenic offspring shows sensitivity to patient status

Abstract

Taking care of offspring during a prolonged period of time is probably one of the most stressful life experiences for parents. The present study compares the cortisol awakening response (CAR) in 38 long-term caregivers (mothers and fathers of schizophrenic relatives) with a control group of 32 non-caregivers. Factors such as general stress, caregiver burden, patient severity, and institutionalization were studied. Although a blunted CAR was observed in caregivers in comparison with controls, this difference was not significant. Among caregivers, the absence of institutionalization for the patient is associated with a lack of CAR in caregivers in comparison with caregivers of institutionally supported patients. General stress, caregiver burden, and patient severity themselves did not favor significant changes in CAR. CAR shows greater sensitivity to institutional support than patient severity and perceived stress. Further research is needed to explain the impact of these factors on health and the psychological factors involved.     

The Role of PTSD and Length of Shelter Stay in Battered Women's Severity of Reabuse after Leaving Shelter

Intimate partner violence (IPV) is associated with significant morbidity, including high rates of reabuse even after women have taken steps to achieve safety. This study evaluated the roles of posttraumatic stress disorder (PTSD) symptom severity and length of shelter stay in the severity of reabuse in 103 IPV victims over a six-month period after leaving a battered women's shelter. Results suggest that the length of shelter stay is inversely related to reabuse severity after leaving shelter. Additionally, more severe PTSD symptoms on shelter exit were associated with greater reabuse severity after leaving shelter. Furthermore, additional study findings support prior research suggesting that the emotional numbing symptoms of PTSD are a significant risk factor for reabuse among IPV victims after leaving shelter.     

Action influences spatial perception: Neuropsychological evidence

We present neuropsychological evidence indicating that action influences spatial perception. First, we review evidence indicating that actions using a tool can modulate unilateral visual neglect and extinction, where patients are unaware of stimuli presented on one side of space. We show that, at least for some patients, modulation comes about through a combination of visual and motor cueing of attention to the affected side (Experiment 1). Subsequently, we review evidence that action‐relations between stimuli reduce visual extinction; there is less extinction when stimuli fall in the correct colocations for action relative to when they fall in the incorrect relations for action and relative to when stimuli are just associatively related. Finally, we demonstrate that action relations between stimuli can also influence the binding of objects to space, in a patient with Balint's syndrome (Experiment 2). These neuropsychological data indicate that perception–action couplings can be crucial to our conscious representation of space.     

Mental health attitudes among Middle Eastern/North African individuals in the United States

ABSTRACT

Middle Eastern/North African (MENA) individuals may have heightened risk for developing mental health problems due to unique cultural stressors. However, traditional cultural and religious practices and beliefs socialised within the family environment may reduce the likelihood of seeking mental health services. This qualitative study aimed to better understand the intersection of cultural, religious, and mental health attitudes among MENA individuals. Semi-structured telephone interviews were conducted with MENA adults who had received therapy services (N?=?13) and were analysed for emergent themes. Respondents reported lack of understanding of mental illness within their communities, and prominent levels of perceived and self-stigma. Families and religious practices/beliefs played an important role in responding to mental illness. Results suggest that incorporating psychoeducation and community awareness campaigns alongside religious services may help to reduce barriers to receiving mental health treatment.
