The learning benefits of teaching: A retrieval practice hypothesis

Teaching educational materials to others enhances the teacher's own learning of those to‐be‐taught materials, although the underlying mechanisms remain largely unknown. Here, we show that the learning‐by‐teaching benefit is possibly a retrieval benefit. Learners (a) solved arithmetic problems (i.e., they neither taught nor retrieved; control group), (b) taught without relying on teaching notes (i.e., they had to retrieve the materials while teaching; teaching group), (c) taught with teaching notes (i.e., they did not retrieve the materials while teaching; teaching without retrieval practice [TnRP] group), or (d) retrieved (i.e., they did not teach but only practised retrieving; retrieval practice group). In a final comprehension test 1 week later, learners in the teaching group, as did those in the retrieval practice group, outperformed learners in the TnRP and control groups. Retrieval practice possibly causes the learning benefits of teaching.     

Offspring Effects of Prenatal Alcohol Exposure from Birth to 25 Years: The Seattle Prospective Longitudinal Study

Before alcohol was generally known to cause birth defects, NIAAA in 1974 began funding a population-based Seattle study on alcohol use and pregnancy outcome. Women receiving prenatal care by mid-pregnancy were recruited (N = 1,529) and interviewed at home. Approximately 500 offspring exposed to a range of alcohol levels were examined on 11 occasions between day 1 and 25 years. Neuropsychological and neurobehavioral performance measures are correlated with prenatal alcohol dose, without substantial confounding by socio-demographic or rearing conditions, smoking, nutrition, or other drugs. Deficits in attention, arithmetic skill, spatial-visual memory, and IQ, as well as increased alcohol problems and psychiatric disorders are among offspring outcomes correlated at several ages with maternal drinking during and before pregnancy recognition. Findings are not confined to women who believed they had alcohol problems. Not all exposed offspring appear affected.     

The effects of co‐occurring ADHD symptoms on electrophysiological correlates of cognitive control in young people with Tourette syndrome

Efficient cognitive control is implicated in tic control in young people with Tourette syndrome (TS). Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with TS and is associated with impaired cognitive control. Young people with TS and ADHD (TS+ADHD) show poorer cognitive control performance than those with TS, but how co‐occurring ADHD affects underlying neural activity is unknown. We investigated this issue by examining behavioural and event‐related potential (ERP) correlates of cognitive control in young people with these conditions. Participants aged 9–17 with TS (n = 17), TS+ADHD (n = 17), ADHD (n = 11), and unaffected controls (n = 20) performed a visual Go/Nogo task during electroencephalography (EEG) recording. Behavioural performance measures (D‐prime, RT, reaction time variability, post‐error slowing) and ERP measures (N2, P3, error‐related negativity (ERN), error positivity (Pe)) were analysed in a 2 (TS‐yes, TS‐no) × 2 (ADHD‐yes, ADHD‐no) factorial analysis to investigate the effects of TS, ADHD, and their interaction. The results of these analyses showed that ADHD was associated with poorer performance and reduced amplitude of all ERPs, reflecting widespread cognitive control impairments. Tourette syndrome was associated with slowed RTs, which might reflect a compensatory slowing of motor output to facilitate tic control. There was no interaction between the TS and ADHD factors for any behavioural or ERP measure, indicating the impairing effects of ADHD on behaviour and electrophysiological markers of cognitive control were present in TS+ADHD and that RT slowing associated with TS was unaffected by co‐occurring ADHD symptoms.     

Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross‐sectional study compared self‐reported alexithymia and observer‐rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self‐reported alexithymia was measured with the Toronto Alexithymia Scale‐20 (TAS‐20) and emotional awareness with an observer‐rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self‐reported alexithymia in the TAS‐20 compared to HC, but had similar emotional awareness capacity in the observer‐rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS‐total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self‐reported alexithymia and observer‐rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS.     

老年甲状腺结节的诊治经验

介绍笔者及科室老年甲状腺结节的诊治经验,对2003年1月至2009年12月期间共收治的144例年龄大于60岁的老年甲状腺结节患者进行分析和总结。老年甲状腺结节以多发为主;压迫症状、异物和不适感、继发性甲状腺功能亢进是老年甲状腺结节患者主要的手术指证;术中发现喉返神经和甲状旁腺有脂肪沉着;病理方面良性结节的钙化率较高;患者术后切口水肿比较明显;暂时性低钙血症的发生率较高;虽然术前麻醉ASA评分较低,但术后心肺并发症的发生率并未上升。老年甲状腺结节患者以全麻为宜,最好采用双甲近全切除术,这不仅可避免术后复发和再次手术率,更可减少甲状腺素制剂的用量,减少药物副作用。     

The social nature of benevolent sexism and the antisocial nature of hostile sexism: Is benevolent sexism more likely to manifest in public contexts and hostile sexism in private contexts?

Previous research converges on demonstrating that benevolent sexism (BS) is socially approved, whereas hostile sexism (HS) is socially disapproved. We postulated that a sample of married women would be likely to report that their husbands express hostile sexist attitudes and engage in related actions towards them more in private than public contexts, where they lie concealed from public censure. By contrast, the women would report that their husbands would be likely to express benevolent sexist attitudes and engage in related actions more in public than private contexts, where they are reinforced not only by their target (i.e. wife), but also by significant others and the society at large. We tested these hypotheses with a sample of Black, heterosexually married Zimbabwean women (n = 109, mean age = 31.83). Results supported our hypotheses: the women reported hostile sexist attitudes and actions to be more likely to occur in private than public contexts; on the other hand, they reported benevolent sexist attitudes and actions to be more likely in public than private contexts. We conclude that differences in social approval of BS and HS account for these results.

Terrorism Between "Syndrome" and "Tool"

ABSTRACT— Two psychological views of terrorism are described, approaching it as a "syndrome" and as a "tool" respectively. Research thus far found little support for the syndrome view. The heterogeneity of terrorism's users is consistent with the tool view, affording an analysis of terrorism in terms of goal–means psychology.     

Meta-Analysis of the Effects of Peer-Administered Psychosocial Interventions on Symptoms of Depression

Many community mental health centers have implemented peer treatment models that employ recovered former clients as cost‐efficient adjunct providers. The effectiveness of these and other peer‐administered interventions (PAIs) for treating depression symptoms has not been well‐established. The current study is a meta‐analysis of PAIs’ effects on depression symptoms. Twenty‐three eligible studies were identified. Study characteristics were coded by multiple raters, random‐effects models were used to compare mean effect sizes, and mixed‐effects models were used to test for moderation. PAIs produced significant pre‐post reductions in depression symptoms (d = .5043 [95 % CI .3675–.6412]). In direct comparisons, PAIs performed as well as non‐peer‐administered interventions (.0848 [?.1455–.3151]), and significantly better than no‐treatment conditions (.2011 [.0104–.3918]). PAIs that involved a professional in a secondary treatment role were significantly less effective than those that were purely peer‐administered, and educational/skills‐based PAIs produced better outcomes than those that were mainly supportive. Follow‐up data, when available, indicated that PAIs’ benefits were maintained. PAIs reduce depression symptoms and warrant further study. The clinical significance of PAIs’ benefits, and whether they are better suited as stand‐alone or adjunct treatments, remain to be established. Implications for the roles of mental health professionals are discussed.
