Subliminal food images compromise superior working memory performance in women with restricting anorexia nervosa

Prefrontal cortex (PFC) is dysregulated in women with restricting anorexia nervosa (RAN). It is not known whether appetitive non-conscious stimuli bias cognitive responses in those with RAN. Thirteen women with RAN and 20 healthy controls (HC) completed a dorsolateral PFC (DLPFC) working memory task and an anterior cingulate cortex (ACC) conflict task, while masked subliminal food, aversive and neutral images were presented. During the DLPFC task, accuracy was higher in the RAN compared to the HC group, but superior performance was compromised when subliminal food stimuli were presented: errors positively correlated with self-reported trait anxiety in the RAN group. These effects were not observed in the ACC task. Appetitive activation is intact and anxiogenic in women with RAN, and non-consciously interacts with working memory processes associated with the DLPFC. This interaction mechanism may underlie cognitive inhibition of appetitive processes that are anxiety inducing, in people with AN.     

The effects of ageing and divided attention on the self-reference effect in emotional memory: Spontaneous or effortful mnemonic benefits?

The self-reference effect (SRE) is a powerful memory advantage associated with encoding in reference to the self (e.g., Rogers, Kuiper, & Kirker, 1977). To explore whether this mnemonic benefit occurs spontaneously, the current study assessed how ageing and divided attention affect the magnitude of the SRE in emotional memory (i.e., memory for emotional stimuli). The sample included a young Full Attention group (young-FA), a young Divided Attention group (young-DA), and an older adult group. The division of attention was manipulated at encoding where participants incidentally studied positive, negative, and neutral trait adjectives in either a self-reference (i.e., rating how well each word describes themselves) or an other-reference condition (i.e., rating how well each word describes another person). Memory for these words was assessed with both recall and recognition tasks. The results from both tasks demonstrated equivalent SRE for all three groups across emotional valence categories of stimuli, suggesting that the SRE is a spontaneous, effortless, and robust effect in memory.     

The latent variable approach as applied to transitive reasoning

We discuss the limitations of hypothesis testing using (quasi-) experiments in the study of cognitive development and suggest latent variable modeling as a viable alternative to experimentation. Latent variable models allow testing a theory as a whole, incorporating individual differences with respect to developmental processes or abilities in the model. Experiments, in contrast, aim at testing hypotheses that refer to a specific part of a theory; also they ignore individual differences or model the individual differences using age group as a proxy for developmental stage. Drawing on a sample of 409 5–13-year olds, we demonstrate the advantages of latent variable models in the area of transitive reasoning. A comparison of three models showed that the latent variable model that represented fuzzy trace theory had a better fit than the models representing Piaget's theory or linear ordering theory.     

Brief cognitive-behavioral internet therapy for irritable bowel syndrome

While cognitive-behavioral therapy for IBS is quite effective, the limited availability of competent therapists and lack of access to treatment remain problematic. This paper reports on a small, randomized, controlled trial of a five week internet based cognitive-behavioral intervention for IBS with limited therapist feedback via e-mail. Fifty-four IBS patients were recruited via the internet and randomly assigned to either immediate treatment or a wait-list control group. Thirty-one subjects completed the post-treatment assessment. 77% of treatment completers also completed a 3-month follow-up assessment. Treatment completers experienced statistically and clinically significant declines in IBS symptoms and improvements in quality of life. Those gains were substantially maintained at follow-up. Treatment efficacy was partially mediated by reductions in the tendency to catastrophize the social and occupational implications of symptoms, suggesting that catastrophizing may be an important target for treatment.     

The Role of Repetitive Negative Thoughts in the Vulnerability for Emotional Problems in Non-Clinical Children

The current study examined the role of repetitive negative thoughts in the vulnerability for emotional problems in non-clinical children aged 8–13 years (N = 158). Children completed self-report questionnaires for assessing (1) neuroticism and behavioral inhibition as indicators of general vulnerability (2) worry and rumination which are two important manifestations of repetitive negative thoughts, and (3) emotional problems (i.e., anxiety, depression, and sleep difficulties). Results demonstrated that there were positive correlations between measures of general vulnerability, repetitive negative thoughts, and emotional problems. Further, support was found for a model in which worry and rumination acted as partial mediators in the relation between neuroticism and symptoms of anxiety and depression. In the case of sleep difficulties, no evidence was obtained for such a mediation model. In fact, data suggested that sleeping difficulties are better conceived as an epiphenomenon of high symptom levels of anxiety and depression or as a risk factor for the development of other types of psychopathology. Finally, besides neuroticism, the temperamental trait of behavioral inhibition appeared to play a unique direct role in the model predicting anxiety symptoms but not in the models predicting depressive symptoms or sleep difficulties. To conclude, the current findings seem to indicate that worry and rumination contribute to children’s vulnerability for anxiety and depression.     

A Terror Management Perspective on the Role of Death-Related Anxiety in Psychological Dysfunction

Building on previous existential theorizing, terror management theory provides a unique approach to conceptualizing the development, maintenance, and impact of psychological disorders. The theory suggests that awareness of mortality creates the potential for anxiety, which is managed by an anxiety-buffering system consisting of one's cultural worldview, self-esteem, and interpersonal attachments. The pursuit of meaning, personal value, and interpersonal connections that motivates much human behavior is driven, in part, by the need to control this potential for death-related anxiety. This article provides an overview of terror management theory and a discussion of its implications for understanding clinical conditions, along with a review of research exploring the roles of death-related anxiety and the anxiety-buffering system in anxiety disorders, posttraumatic stress disorder, and depression.     

The utility of socio-demographics,knowledge and health belief model variables in predicting reattendance for mammography screening: A brief report

Abstract

The aims of the present study were to investigate socio-demographic and knowledge variables as predictors of re attendance for mammography screening and to examine the utility of the Health Belief Model (HBM) in predicting reattendance for mammography screening above and beyond socio-demographic and knowledge variables. A total of 88 reattenders and 44 non-reattenders of an Australian breast screening service completed a questionnaire assessing socio-demographics (age, marital status, education, physician recommendation and family history), knowledge and HBM variables. Results showed that reattenders were more likely to be older, married and report physician involvement than non-reattenders. Family history and knowledge did not significantly predict reattendance. Of the HBM variables, perceived benefits was related to reattendance above and beyond socio-demographics. Results support the utility of the HBM as a focus for improving regular attendance for breast screening. It is concluded that non-reattenders should be investigated as a seperate group to women who have never attended for mammography screening.     

Evaluating Contingent Workers as a Recruitment Source for Full‐time Positions

The popularity of contingent work arrangements means that many people now begin working for organizations in a temporary capacity. However, no research has examined how contingent workers converted to full‐time status compared with new hires that are recruited from other sources. In this study, we found that converted contingent workers performed as well as new hires recruited externally through employee referral or online advertisements, but not as well as employees sourced internally from the organization, 1 year after being hired. However, contingent workers did not differ from other recruiting sources in their start‐up time or in how satisfied their managers were with their early adjustment two months after hire.     

That's More Like It: Multiple Exemplars Facilitate Word Learning

Previous research indicates learning words facilitates categorisation. The current study explores how categorisation affects word learning. In the current study, we investigated whether learning about a category facilitates retention of newly learned words by presenting 2‐year‐old children with multiple referent selection trials to the same object category. In Experiment 1, children either encountered the same exemplar repeatedly or encountered multiple exemplars across trials. All children did very well on the initial task; however, only children who encountered multiple exemplars retained these mappings after a short delay. Experiment 2 replicated and extended this finding by exploring the effect of within‐category variability on children's word retention. Children encountered either narrow or broad exemplars across trials. Again, all children did very well on the initial task; however, only children who encountered narrow exemplars retained mappings after a short delay. Overall, these data offer strong evidence that providing children with the opportunity to compare across exemplars during fast mapping facilitates retention. Copyright © 2013 John Wiley & Sons, Ltd.
