前瞻记忆的神经机制：来自临床研究的证据

前瞻记忆是指对预定事件或行为的记忆。本文总结了前瞻记忆脑机制相关的文献,介绍了前额皮层、丘脑,内侧颞叶等脑区域在前瞻记忆中的作用,并通过分析注意缺陷多动障碍儿童、老年痴呆症患者、酒精依赖症和内侧颞叶癫痫患者前瞻记忆的表现,从临床角度深入探讨了前瞻记忆神经机制的问题。证据表明,前额皮层参与前瞻记忆的编码、提取和监控过程,与意向保持也有密切的关系;丘脑与意向的执行有关,并且与前额叶互动在前瞻记忆监控中起着重要的作用;内侧颞叶与编码来源的提取和意向的激活都有密切的关系。研究认为前额皮层在前瞻记忆加工过程中起着核心的作用,同时与丘脑、内侧颞叶等区域相互作用,共同成为前瞻记忆编码、保持、提取、执行的神经基础。     

Dimensional schizotypy,autism, and unusual word associations in artists and scientists

Studies from a range of perspectives provide evidence for a relationship between creativity and the tendency to mental illness. The present study further examined this issue by administering questionnaires measuring the minor features of psychosis and autism to 31 professional “artists” (visual artists and musicians) and 28 professional “scientists” (biological scientists and physical scientists/mathematicians). The Oxford–Liverpool Inventory of Feelings and Experiences (O–LIFE), the Hypomanic Personality Scale, and the Autism-Spectrum Quotient (AQ), were administered, in addition to a shortened form of the Kent–Rosanoff Word Association Scale. The results provided strong support for the connection of artistic creativity to positive schizotypy and hypomania and the tendency to make unusual word associations, and somewhat weaker support for the connection of scientific creativity to certain components of the autism spectrum.     

自闭症谱系障碍儿童心理测评的回溯与探索

自闭症谱系障碍(ASD)儿童是一群已引起高度关注的群体,因其兼具社会发展、人际交流障碍等于一身,更因其中大部分儿童还伴有认知,言语发展和情绪障碍,对其进行心理测评是一个极为艰巨和重要的课题.本文从诊断性、认知性和教育干预三个方面对ASD儿童的心理测评进行了述评.同时还阐述了在此基础上建构"会聚式"、"分层式"和"分类式"ASD儿童心理测评体系之构想.     

Perceived agency in retirement and retiree drinking behavior: Job satisfaction as a moderator

Based on recent findings that post-retirement adjustment may be influenced by the conditions leading up to the decision to retire, we examine the impact of individual agency in the retirement decision on problematic drinking behavior, as well as the extent to which such an effect may itself depend upon the valence of the pre-retirement work experience. Using a sample of 304 blue-collar retirees, our findings indicate that, when controlling for pre-retirement drinking behavior, perceptions of retirement as the result of a more forced or involuntary decision are associated with greater alcohol consumption, while perceptions of retirement as the result of a more volitional or voluntary process are associated with lower levels of alcohol consumption and a lower risk of problematic drinking behavior. Our results also indicate that pre-retirement job satisfaction amplifies the former relationship, while attenuating the latter one.     

Implicit theories of intelligence and IQ test performance in adolescents with Generalized Anxiety Disorder

During the past decade, several studies have reported positive effects of cognitive-behavioral therapy (CBT) in the treatment of children and adolescents with mental disorders. One of the most important CBT interventions is to teach children and adolescents to challenge negative thoughts that lead to maladjusted behaviors. Based on the implicit theories of intelligence framework, the main purpose of this study was to test whether an incremental theory manipulation could be used to affect IQ test performance in adolescents with Generalized Anxiety Disorder (GAD). Results showed that patients demonstrated enhanced IQ performance and experienced less state anxiety when they were exposed to an incremental theory of intelligence manipulation. Our findings suggest that incremental theory manipulation provides a useful cognitive strategy for addressing school-related anxiety in adolescents with mental disorders such as GAD.     

Anxiety and post-traumatic stress symptoms following wisdom tooth removal

The purpose of the present study was to determine the psychological impact of wisdom teeth removal and to identify the psychological risk factors for the development of dental anxiety and post-traumatic stress symptoms. Participants were 34 consecutive elective patients referred for surgical removal of a wisdom tooth under local anesthesia. Frequency of previous distressing dental events and general traumatic life events were assessed at baseline (t1), and emotional distress (pain, state anxiety and disturbance) immediately after treatment (t2). Post-traumatic stress responses were determined three days after treatment (t3), and at four weeks follow-up (t4), while severity of dental trait anxiety was assessed at t1 and at t4. Two patients (8%) met screening criteria for Post-Traumatic Stress Disorder (PTSD) at t4. Multivariate analysis revealed that previous exposure to distressing dental events and pre-operative anxiety level predicted anxiety level at t4, accounting for 71% of the variance. Severity of pain during treatment was a significant predictor variable of PTSD symptom severity at t4 (25% explained variance). The findings underline the importance of pain-free treatments and awareness of patients' individual predisposition to anxiety or trauma-related symptoms to reduce the risk of iatrogenic psychological harm.     

Effects of message framing and temporal context on college student drinking behavior

This study evaluated the interactive effects of message framing and temporal context on college student alcohol use. Participants (n = 228) were randomly assigned to read an alcohol prevention message that varied by message frame (gains vs. losses) and temporal context (short- vs. long-term consequences). Participants returned to the lab one month later to report their drinking behavior over the past month. As predicted, students exposed to the gain-framed message reported lower alcohol use (drank less frequently, drank fewer alcoholic beverages per drinking occasion, and engaged in less binge drinking) as compared to students exposed to the loss-framed message, but only if they read about short-term consequences of alcohol use. Message frame had no effect when participants were exposed to long-term consequences. This investigation extends previous research by demonstrating the effectiveness of message framing for reducing health-damaging behaviors and by identifying temporal context as a moderator of framing effects.     

An application of DSM-IV's outline for cultural formulation: Understanding conduct disorder in Latino adolescents

In the established guidelines for providers of services to ethnic, linguistic, and culturally diverse populations, the American Psychological Association addressed the need for practitioners to consider the role that culture and ethnicity plays in the psychosocial development of culturally diverse populations. Currently, there are over 24 million Latinos in the United States, and this population is expected to quadruple in size to over 81 million in the year 2050. This discussion of a case example highlights the appropriateness of utilizing the outline for cultural formulation in working with Latino adolescents diagnosed with Conduct Disorder. As indicated by the DSM-IV's outline for cultural formulation, this discussion addresses the importance of assessing the following: 1) Cultural identity of the individual; 2) Cultural explanations of the individual's illness; 3) Cultural factors related to psychosocial environment and levels of functioning; 4) Cultural elements of the relationship between the individual and the clinician; 5) Overall cultural assessment for diagnosis and care. In particular, the discussion focuses on specific reasons why the utilization of the outline for cultural formulation can greatly assist the clinician in understanding many psychosocial elements unique to treating Conduct Disorder in the Latino adolescent.
