The bedside manner of homo economicus: How and why priming an economic schema reduces compassion

We investigate how, why and when activating economic schemas reduces the compassion that individuals extend to others in need when delivering bad news. Across three experiments, we show that unobtrusively priming economic schemas decreases the compassion that individuals express to others in need, that this effect is mediated by dampened feelings of empathy and heightened perceptions of unprofessionalism, and that it is circumscribed to bad news that has economic implications. We discuss implications for theory and research on schemas, procedural justice, emotion expression, and prosocial behavior.     

Relationship between reaction time variability and motor skill development in ADHD

Slower and more variable reaction times to computerized tasks have been documented in children diagnosed with attention deficit/hyperactivity disorder (ADHD). Recent research supports a role for attentional lapses in generating abnormally variable and slow responses. However, given the association between ADHD and impairments in motor control, we hypothesized that slower or more variable reaction times might also correlate with motor development. The aim of this case-control study was to explore the relationship between motor function, reaction speed and variability, and ADHD. After comprehensive educational and clinical assessments, motor skill development was evaluated in 35 children ages 9 to 14 (19 with ADHD) using the Physical and Neurological Examination for Subtle Signs (PANESS) test battery. Finger-sequencing speed and variability were quantified with goniometers. Reaction times were measured with 20 trials each of computerized simple and choice (binary) tasks. Compared to healthy controls, children with ADHD had slower and more variable reaction times, and these findings correlated with impaired motor development (PANESS) and slow and variable finger sequencing (goniometers). Further studies of motor development in ADHD may identify factors influencing speed and variability of reaction times.

膀胱肿瘤标记物的研究进展

膀胱癌在我国是泌尿系统中最常见的恶性肿瘤.目前,膀胱癌的诊断主要依赖于尿细胞学检查及膀胱镜检查.这些检查都有各自的缺陷.膀胱肿瘤具有自身独特的分子标记物,可以被用来早期诊断、监测复发及评估预后,且为无创检查.因此检测肿瘤标记物正日益受到重视,成为研究的热点.在此我们就膀胱肿瘤标记物的研究进展进行综述.     

青少年攻击行为与友谊质量的交叉滞后回归分析

该研究采用问卷法,对湖北省一所初级中学二年级青少年进行了一个学年的纵向追踪研究,使用Bjorkquist等人编制的直接和间接攻击量表(DIA)以及Parker和Asher编制的友谊质量问卷(FQQ)测查青少年的身体攻击和友谊质量。然后采用二元交叉滞后回归分析法考察了初中二、三年级学生在一个学年中的攻击行为与友谊质量(总问卷及分问卷得分)的关系。结果表明,在控制了前测"肯定与关心"得分后,身体攻击显著地负向预测了"肯定与关心"得分。在控制了前测的"冲突解决策略"得分后,攻击行为边缘显著地预测了后测的"冲突解决策略"得分。同时发现,后测"身体攻击"和"冲突与背叛"不存在显著的相关。     

伊斯兰教与世俗化问题再思考

宗教作为一种社会存在、社会文化形态,它与人类社会是双向互动的。社会生活世俗化与社会宗教道德规范化、制度化,在任何人类社会都是互有联系和区别的现象。本文以伊斯兰教历史上三个有代表性的时间节点为线索,就其与世俗化的关系问题进行了一些学理上的梳理。     

Dopamine D1 receptors are responsible for stress-induced emotional memory deficit in mice

It is established that stress impairs spatial learning and memory via the hypothalamus-pituitary-adrenal axis response. Dopamine D1 receptors were also shown to be responsible for a stress-induced deficit of working memory. However, whether stress affects the subsequent emotional learning and memory is not elucidated yet. Here, we employed the well-established one-trial step-through task to study the effect of an acute psychological stress (induced by tail hanging for 5, 10, or 20?min) on emotional learning and memory, and the possible mechanisms as well. We demonstrated that tail hanging induced an obvious stress response. Either an acute tail-hanging stress or a single dose of intraperitoneally injected dopamine D1 receptor antagonist (SCH23390) significantly decreased the step-through latency in the one-trial step-through task. However, SCH23390 prevented the acute tail-hanging stress-induced decrease in the step-through latency. In addition, the effects of tail-hanging stress and/or SCH23390 on the changes in step-through latency were not through non-memory factors such as nociceptive perception and motor function. Our data indicate that the hyperactivation of dopamine D1 receptors mediated the stress-induced deficit of emotional learning and memory. This study may have clinical significance given that psychological stress is considered to play a role in susceptibility to some mental diseases such as depression and post-traumatic stress disorder.     

The Three Domains of Disgust Scale: factor structure, psychometric properties, and conceptual limitations

This investigation examined the measurement properties of the Three Domains of Disgust Scale (TDDS). Principal components analysis in Study 1 (n = 206) revealed three factors of Pathogen, Sexual, and Moral Disgust that demonstrated excellent reliability, including test-retest over 12 weeks. Confirmatory factor analyses in Study 2 (n = 406) supported the three factors. Supportive evidence for the validity of the Pathogen and Sexual Disgust subscales was found in Study 1 and Study 2 with strong associations with disgust/contamination and weak associations with negative affect. However, the validity of the Moral Disgust subscale was limited. Study 3 (n = 200) showed that the TDDS subscales differentially related to personality traits. Study 4 (n = 47) provided evidence for the validity of the TDDS subscales in relation to multiple indices of disgust/contamination aversion in a select sample. Study 5 (n = 70) further highlighted limitations of the Moral Disgust subscale given the lack of a theoretically consistent association with moral attitudes. Lastly, Study 6 (n = 178) showed that responses on the Moral Disgust scale were more intense when anger was the response option compared with when disgust was the response option. The implications of these findings for the assessment of disgust are discussed.     

Treatment of PTSD in Older Adults: Do Cognitive-Behavioral Interventions Remain Viable?

The literature examining trauma among older adults is growing, but little is known about the efficacy of empirically supported interventions for PTSD within this population. Clinical writing on this topic often implies that cognitive-behavioral treatments may be ineffective or inappropriate for older adults with PTSD given physical and/or cognitive vulnerabilities. Review of the limited research in this area, however, provides little support for the claim that cognitive-behavioral interventions are ineffective in treating PTSD among the elderly. In an effort to explicate specific issues related to treatment process and outcome among older survivors of trauma, a case series is presented outlining the treatment of three older adults within the context of a structured, cognitive-behavioral group intervention. Observations from this case series suggests that cognitive-behavioral interventions continue to be useful in treating PTSD with this population. Specific treatment issues unique to older adults are explored and recommendations for future research are discussed.
