Age and age of acquisition: An evaluation of the cumulative frequency hypothesis

An important determinant of picture and word naming speed is the age at which the names were learned (age of acquisition). Two related interpretations of these effects are that they reflect differences between words in their cumulative frequency of use, or that they reflect differences in the amount of time early and lateacquired words have spent in lexical memory. Both theories predict that differences between early and late-acquired words will be less apparent in older than younger adults. Two experiments are reported in which younger and older adults read words varying in age of acquisition or frequency, or named objects varying in age of acquisition. There was an observed effect of word frequency only for young adults' word naming. In contrast, strong age of acquisition effects were found for both the young and the old participants. The implications of these results for theories of how age of acquisition might affect lexical processing are discussed.     

A Review of Spiritual and Religious Measures in Nursing Research Journals: 1995--1999

Background: A series of systematic reviews has revealed relatively high levels of interest in religion and spirituality in different nursing specialties, but not in general nursing research journals. Purpose: To identify the extent to which spirituality and religiousness were measured in all quantitative and qualitative research articles published in Research in Nursing and Health, Nursing Research, Advances in Nursing Science (ANS), and Image: The Journal of Nursing Scholarship from 1995 to 1999. Methods: A full-text search was conducted of ANS and Image using the Ovid search system. Nursing Research and Research in Nursing and Health were hand searched for spiritual/religious measures. Characteristics of selected studies, the measures taken, and their uses were coded for data analysis. Results: A total of 564 research studies were identified, of which 67 (11.9%) included at least one measure of spirituality or religiousness. A significant difference was found between the percentage of qualitative and quantitative studies that contained measures of these concepts. Of the 119 qualitative studies, 23 (19.3%) contained a measure of religion or spirituality, compared to 44 of the 445 (9.9%) quantitative studies. Nominal indicators of religious affiliation were the most commonly used measures in the quantitative studies and measures of religion and spirituality were rarely used in the analyses. Although only a few quantitative or qualitative studies intended to focus on religion or spirituality, these themes often emerged spontaneously in the qualitative research. Conclusions: Research in Nursing and Health, Advances in Nursing Science, Nursing Research, and Image: The Journal of Nursing Scholarship all published research measuring spirituality and religiousness during the time-period studied. The rate at which spirituality and religion appeared in these nursing research articles is substantially higher than that found in most fields outside of nursing. Even more frequent inclusion of spiritual and religious variables and richer measures of spirituality and religiousness would help to increase the available scientific information on the role of spirituality and religion in nursing care.     

A Synopsis of Rational-Emotive Behavior Therapy (REBT); Fundamental and Applied Research

The article presents a synopsis on rational-emotive behavior therapy (REBT), its fundamental theoretical framework, its applications, and future directions. The paper is organized according to the following structure: in part one, REBT fundamental/basic research is discussed; in the second part clinical/applied research in REBT is presented, including aspects of efficacy and effectiveness, discrimination of disorders for which REBT works most effectively, and its relations to other therapies. Uses and misuses of REBT and their impact on research and future developments are presented as well. While it is true that REBT research has many shortcomings, the overgeneralization and/or magnification of the negative, and the minimization of the positive are dysfunctional beliefs that maintain the false idea in the field that REBT has few empirical studies and that REBT research is in serious trouble. A balanced approach, analyzing both the strengths and weakness, suggest that REBT has hundreds of research articles and that high-quality studies tend to support REBT’s basic theory and efficacy. However, to strengthen this conclusion and to fully explore the potential of REBT, shortcomings of REBT research need to be corrected, and high-quality studies promoted. This is particularly important since, although effective, cognitive-behavioral psychotherapies have not yet reached “the desired standard” of efficacy and effectiveness, as about 30–40% of people are still nonresponsive to these interventions Thus, REBT could be a platform of reinvigorating empirical studies on the efficacy/effectiveness and theory of cognitive-behavioral models of psychopathology and human functioning.

Conflict of interest in biomedical research: a view from Europe

In this paper I address the conflict of interest (CoI) issue from a legal point of view at a European level. We will see that the regulatory framework that exists in Europe does state the need for the independence of ethics committee involved in authorisation of research and clinical trials. We will see that CoI is an element that has to be closely monitored at National and International level. Therefore, Member States and Newly Associated States do have to address CoI in the authorisation process of research and clinical protocols of biomedicine. The opinions here expressed are personal and do not commit the European Commission. An earlier version of this paper was delivered at a Conference on Conflict of Interest and Its Significance in Science and Medicine, 5–6 April, 2002, Warsaw, Poland. The author is a Scientific Officer in the Programme Science and Society dealing with ethics and science (Unit C.3).     

Behavioral Family Interventions for Improving Child-rearing: A Review of the Literature for Clinicians and Policy Makers

This paper reviews evidence that behavioral family interventions are effective at improving child-rearing in distressed families and families with children exhibiting disruptive behavior. Essential therapeutic strategies offered within a collaborative therapeutic process are identified. Exemplary materials for parents and clinicians are identified. Differences between behavioral family interventions and two popular press parenting approaches are highlighted, including the lack of empirical support for these widely used programs and the advice they offer which runs counter to behavioral approaches. Recommendations are offered for combining behavioral family interventions with other empirically supported approaches, promoting more widespread use of empirically supported treatments, such as behavioral family interventions, and the need for a public health perspective on family functioning, involving collaboration among clinicians, policy makers, and researchers.     

Neurology and neuropathology of Soman-induced brain injury: an overview.

Battlefield use of nerve agents poses serious medical threats to combat troops and to civilians in the immediate or adjacent environment. The experiments reported herein were carried out in the 1980s to help to define both the neurological and neuropathological consequences of exposure to the organophosphate nerve agent Soman. These data contributed to the scientific foundation for a program of drug development to find agents that would prevent or reduce the risk of injury to the central nervous system and specifically pointed to the importance of including an anticonvulsant in the treatment of agent exposure. Since these experiments were conducted, research efforts have continued to improve pretreatment and treatment, such as the inclusion of the anticonvulsant diazepam in the medical treatment of exposed personnel.     

情绪效价可预测性对时间捆绑效应的影响

时间捆绑效应指的是主观上主动动作和动作结果的时间点相互靠近的现象。其中, 时间捆绑效应可分为动作捆绑和结果捆绑, 分别对应主动动作和动作结果的时间点变化。本研究通过一个混合设计实验考察了情绪效价可预测性对时间捆绑效应的影响。情绪效价可预测性(可预测、不可预测)为被试内因素, 刺激模态(听觉刺激、视觉刺激)为被试间因素。结果发现, 情绪效价为可预测时, 结果捆绑在主动按键后产生听觉刺激或视觉刺激都出现了增强, 而动作捆绑仅在产生视觉刺激时才出现增强。结果表明, 情绪效价为可预测时会增强时间捆绑效应, 但该作用在动作捆绑和结果捆绑中存在差异。由于时间捆绑效应是反映主动控制感的主要指标, 本研究结果对先进驾驶辅助系统的交互设计具有一定的参考意义。     

利手与内隐左右空间情感效价关系的眼动研究

为探明手动作流畅性和情感材料呈现空间在不同利手者左右空间情感偏好中的关系,本研究将情绪Stroop范式和眼动测量相结合,通过反应速度和眼动数据将动作流畅性和空间情感注意偏向相分离,并考察其交互作用。结果发现右利手个体的反应速度存在优势手效应,不同利手者在使用左手时表现出对优势手同侧空间的内隐情感偏好,表明右利手个体的反应速度存在优势手流畅性的主导作用,手动作流畅性和内隐空间情感偏好的作用可以分离。     

奖赏结构与结果效价对儿童自我—他人成就归因与评价的影响

本研究旨在考察不同的奖赏结构和结果效价对儿童自我-他人成就归因、自我-他人奖赏评价的影响。实验采用2×2×2混合设计,其中自我-他人归因与评价为被试内设计。被试为小学五年级学生74名(男生36人,女生38人),实验通过解决一系列迷津测验来创设成功和失败情境。实验结果表明,奖赏结构对儿童自我-他人能力归因的影响、奖赏结构与自我-他人归因的交互作用对能力归因的影响、自我-他人运气归因均达到了显著性水平;努力和任务难度归因不显著;儿童对自我和他人的成就结果倾向于做能力和运气归因,较为忽略努力和任务难度在成就行为中的作用。     

A systematic review of interventions for adults who stutter

PurposeTo examine the effectiveness of (i) face to face interventions (ii) models of service delivery and (iii) psychological treatments combined with speech-focused interventions for adults who stutter.MethodsFive electronic databases and three clinical trial registries were searched. Systematic reviews, randomised controlled trials (RCTs) and studies that applied an intervention with adults who stutter were included. Pharmaceutical interventions were excluded. Primary outcomes included a measure of stuttering severity. Risk of bias assessment was conducted on included studies and overall quality of the evidence was graded.ResultsFive RCTS, four registered trials and three systematic reviews met inclusion criteria. Intervention approaches included speech restructuring programs (e.g. Camperdown Program) and transcranial direct current stimulation (tDCS). One study investigated cognitive behaviour therapy (CBT) alongside speech restructuring. Overall, studies were classified low risk of bias and good quality. Speech restructuring was included in all but one study (tDCS study) and had the most evidence i.e. supported by the greatest number of RCTs. On average, stuttering frequency was reduced by 50–57 % using speech restructuring approaches. No study reduced stuttering to the same level as community controls who don’t stutter. The study on tDCS reduced stuttering frequency by 22–27 %. Speech restructuring delivered via telehealth was non-inferior to face-to-face intervention. One study reported CBT was an effective adjunct to speech restructuring interventions.ConclusionSpeech restructuring interventions were found to reduce stuttering in adults, however degree and maintenance of fluency varied. The body of evidence surrounding tDCS and psychological interventions is limited. Replication studies should be considered.
