Training the brain: fact and fad in cognitive and behavioral remediation

Putatively safe and effective for improving cognitive performance in both health and disease, products purported to train the brain appeal to consumers and healthcare practitioners. In an increasingly health-centered society, these applications constitute a burgeoning commercial market. Sparse evidence coupled with lack of scientific rigor, however, leaves claims concerning the impact and duration of such brain training largely unsubstantiated. On the other hand, at least some scientific findings seem to support the effectiveness and sustainability of training for higher brain functions such as attention and working memory. In the present paper we provide a tectonic integration and synthesis of cognitive training approaches. Specifically, we sketch the relative merits and shortcomings of these programs, which often appeal to parents who must choose between side-effect-laden medication and other less conventional options. Here we examine how neuroplasticity allows the healthy as well the impaired to benefit from cognitive training programs. We evaluate the evidence and consider whether brain training can be a stand-alone treatment or an adjunct to pharmacotherapy, outline promising future prospects, and highlight what training outcomes are plausible in line with available data. Future research would determine whether the field of brain training realizes its potential to revolutionize education and rehabilitation or withers away engulfed in controversy.     

The Santa Clara Strength of Religious Faith Questionnaire (SCSORF): A Validation Study on Iranian Muslim Patients Undergoing Dialysis

The Santa Clara Strength of Religious Faith Questionnaire (SCSORF) is an often used and validated scale that is uncommonly utilized in culturally diverse populations. The purpose of this research investigation was to adapt the SCSORF for use among Iranian Muslim patients undergoing dialysis and to examine the reliability and validity of the scale among this population. A total of 428 patients (228 females, 200 males, M age = 52.2 years, SD = 10) were selected from five dialysis center in Tehran and Qazvin, Iran. A comprehensive forward–backward translation system was used for cross-cultural translation. Patients completed a baseline questionnaire obtaining demographic and clinical information as well as the SCSORF, the Age Universal Religious Orientation Scale (AUROS), the religious life inventory (RLI), and the Duke University religion index (DUREL). 2 weeks later, patients were asked to complete the SCSORF once again. Reliability of the SCSORF was examined using internal consistency and test-rest reliability. Convergent validity and factor structure using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were also examined. Cronbach’s α for the single construct of the SCSORF was 0.89 with adequate test–retest reliability measured over a 2 week period. SCSORF scores were significantly correlated with AUROS, RLI and the DUREL. The EFA generated a single factor solution for the SCSORF while these results were confirmed by the CFA in an independent sample. Findings demonstrated that the SCSORF has favorable reliability, convergent validity, and divergent validity among Iranian Muslim patients undergoing dialysis and is recommended for use by clinicians (e.g., nephrologists) to measure strength of religious faith among patients.     

The prefrontal cortex in sleep

Experimental data indicate a role for the prefrontal cortex in mediating normal sleep physiology, dreaming and sleep-deprivation phenomena. During nonrandom-eye-movement (NREM) sleep, frontal cortical activity is characterized by the highest voltage and the slowest brain waves compared to other cortical regions. The differences between the self-awareness experienced in waking and its diminution in dreaming can be explained by deactivation of the dorsolateral prefrontal cortex during REM sleep. Here, we propose that this deactivation results from a direct inhibition of the dorsolateral prefrontal cortical neurons by acetylcholine, the release of which is enhanced during REM sleep. Sleep deprivation influences frontal executive functions in particular, which further emphasizes the sensitivity of the prefrontal cortex to sleep.     

Infertility and Adjustment in Women: The Effects of Attachment Style and Social Support

The moderating effects of two psychological resources—attachment style and perceived social support—on adjustment were studied in 109 infertile women, examining the effects of duration of infertility and of primary (the woman has no child of her own) versus secondary (the woman already has a child of her own) infertility. Subjects were administered questionnaires measuring marital adjustment, psychological distress, and well-being. A model viewing attachment style and social support as moderators between stress psychological well-being was explored. The results showed that among the objective characteristics, only duration of infertility had any impact on the psychological measures. Furthermore, the psychological resources were highly associated with the adjustment scores in general. A hierarchical regression analysis showed that attachment style and social support both were related to marital quality and to psychological well-being and that these two resources function as stress moderators. It was concluded that attachment style and social support are important resources for individuals in times of stress, as exemplified in the infertility situation.     

Tomboyism,Sexual Orientation,and Adult Gender Roles Among Israeli Women

The purpose of this study was to examine self-reported connections between sexual orientation (SO) and tomboyism in an Israeli sample. This study also focused on the connection between tomboyism and adult gender roles, and between gender roles and SO. A sample of 127 participants was solicited from lesbian organizations and from workplaces. Participants' SO was self-defined twice, using a forced choice and a Kinsey-type scale. Results revealed a connection between tomboyism and lesbianism. The overall level of tomboyism was lower then reported elsewhere. A relationship between tomboyism and gender roles emerged only for adolescence, and SO was only marginal related to gender roles. The definitions of tomboyism, cultural effects, Israeli society, adolescence gender roles, and bisexualism are discussed.
