White matter hyperintensities and working memory: an explorative study

White matter hyperintensities (WMH) are commonly observed in elderly people and may have the most profound effect on executive functions, including working memory. Surprisingly, the Digit Span backward, a frequently employed working memory task, reveals no association with WMH. In the present study, it was investigated whether more detailed analyses of WMH variables and study sample selection are important when establishing a possible relationship between the Digit Span backward and WMH. To accomplish this, the Digit Span backward and additional working memory tests, WMH subscores, and cardiovascular risk factors were examined. The results revealed that performance on the Digit Span backward test is unrelated to WMH, whereas a relationship between other working memory tests and WMH was confirmed. Furthermore, a division between several white matter regions seems important; hyperintensities in the frontal deep white matter regions were the strongest predictor of working memory performance.

Is obsessive-compulsive disorder a disturbance of security motivation? Comment on Szechtman and Woody (2004)

H. Szechtman and E. Woody (2004) proposed that obsessive-compulsive disorder (OCD) is caused by a malfunctioning brain security motivation system. In the current article, the authors' review of the model suggests that it is limited in the following ways: (a) It is built on a selective review of the empirical literature, (b) it offers no explanation for many important OCD phenomena, (c) it fails to distinguish OCD from generalized anxiety disorder, (d) some of the model's predictions are ambiguous or unfalsifiable, and (e) other predictions are refuted by previously published research. Models proposing that OCD is caused by a single dysfunctional mechanism, such as the security motivation model, have difficulty explaining the complexity and heterogeneity of OCD.     

Adult attachment,the transition to parenthood,and depressive symptoms

Testing a model suggested by J. Bowlby (1988), this study investigated how a personal vulnerability (attachment ambivalence) interacts with perceptions of deficient spousal support before and during a major life stressor (the transition to parenthood) to predict pre-to-postnatal increases in depressive symptoms. Highly ambivalent women who entered parenthood perceiving either less support or greater anger from their husbands experienced pre-to-postnatal increases in depressive symptoms at 6 months postpartum. The associations between these 2 prenatal interaction terms and pre-to-postnatal increases in depressive symptoms were mediated by perceptions of declining spousal support across the transition period. Moreover, for highly ambivalent women, the association between prenatal and postnatal depression scores was mediated by perceptions of the amount of support available from their husbands.     

Overlapping Consensus or Marketplace of Religions? Rawls and Smith

In this paper, I examine the claim that Rawls’s overlapping consensus is too narrow to allow most mainstream religions’ participation in political discourse. I do so by asking whether religious exclusion is a consequence of belief or action, using conversion as a paradigm case. After concluding that this objection to Rawls is, in fact, defensible, and that the overlapping consensus excludes both religious belief and action, I examine an alternative approach to managing religious pluralism as presented by Adam Smith. I show that Smith’s so-called “marketplace of religions” assumes and encourages religious conversion. I then offer objections to Smith’s approach from Rawls’s point of view, concluding that, while Rawls cannot adequately respond to the Smithian challenge, in the end the two positions are complimentary.     

Transitional object use,attachment, and help‐seeking behaviour in Taiwanese adolescents

Transitional object use is psychologically beneficial for young children, but research has suggested that maintaining transitional object use into middle childhood may be associated with negative behaviour. Little is known about the continuation of transitional object use into adolescence, and few studies have been conducted with non‐Western populations. To examine differences in attachment and attitudes to help seeking in adolescents who did and did not use a transitional object, 723 adolescents from Taiwan (M age = 14 years) were asked about their current and past use of transitional objects. Measures of attachment were obtained using the Revised Adult Attachment Scale, and attitude toward help was measured using the Attitudes Toward Seeking Professional Psychological Help Scale. In total, 37% of the sample continued transitional object use in adolescence. Current use of a transitional object differentiated the sample on the measures of attachment and help seeking. Transitional object users were less likely to have secure attachments and less likely to express positive attitudes toward seeking help. Transitional object use is prevalent in Taiwanese adolescents, and we suggest that continued use of a transitional object acts as an indicator of potential withdrawal from support offered in schools.     

Is Attachment to God a Unique Predictor of Mental Health? Test in a Jewish Sample

Research suggests that religion and spirituality generally correlate positively with various aspects of mental health, although mediators remain unclear. We explored whether attachment to God is a unique predictor above and beyond other key religious variables within a Jewish sample. Given the religion-as-culture perspective suggesting that Judaism can be characterized as primarily focused on behavior versus internal mental experiences, we expected that attachment to God would be less relevant to Jewish mental health. Surprisingly, attachment emerged as the strongest predictor of mental health among both more traditional Orthodox Jewish participants and less traditional non-Orthodox Jews. Although additional cross-cultural research is clearly needed, our results suggest that even in more behaviorally focused religious cultures, attachment to God is a key mediator of the protective effects of religion and spirituality.     

Efficacy of and preference for reinforcement and response cost in token economies

Researchers have shown that both differential reinforcement and response cost within token economies are similarly effective for changing the behavior of individuals in a group context (e.g., Donaldson, DeLeon, Fisher, & Kahng, 2014; Iwata & Bailey, 1974). In addition, these researchers have empirically evaluated preference for these procedures. However, few previous studies have evaluated the individual effects of these procedures both in group contexts and in the absence of peers. Therefore, we replicated and extended previous research by determining the individual effects and preferences of differential reinforcement and response cost under both group and individualized conditions. Results demonstrated that the procedures were equally effective for increasing on‐task behavior during group and individual instruction for most children, and preference varied across participants. In addition, results were consistent across participants who experienced the procedures in group and individualized settings.     

Selective visual attention and perceptual coherence

Conscious perception of the visual world depends on neural activity at all levels of the visual system from the retina to regions of parietal and frontal cortex. Neurons in early visual areas have small spatial receptive fields (RFs) and code basic image features; neurons in later areas have large RFs and code abstract features such as behavioral relevance. This hierarchical organization presents challenges to perception: objects compete when they are presented in a single RF, and component object features are coded by anatomically distributed neuronal activity. Recent research has shown that selective attention coordinates the activity of neurons to resolve competition and link distributed object representations. We refer to this ensemble activity as a "coherence field", and propose that voluntary shifts of attention are initiated by a transient control signal that "nudges" the visual system from one coherent state to another.
