自恋人格调节信任博弈的结果评价

自恋人格个体表现出亲社会行为的减少和对他人的反馈敏感。信任是人类社会互动行为的基础,自恋人格特质可能影响他们的信任决策。为了探究自恋水平如何影响信任博弈中结果评价的大脑活动,本研究采用事件相关电位技术记录了38名被试完成单次信任博弈时的脑电波。行为结果发现相对高自恋者的信任选择率显著低于相对低自恋者的信任选择率。脑电结果表明,相对高自恋者信任损失反馈减互惠获利反馈所得的FRN差异波(d FRN)显著地大于相对低自恋者,并且相对高自恋者结果评价诱发的P300波幅显著地大于相对低自恋者。本研究提供了自恋人格个体信任博弈中结果评价的初步神经电生理学证据。     

选择一致性影响结果评价的ERP研究

本研究通过两个实验探讨了当被试主动做出与他人一致/不一致的选择行为(实验1)或看到他人做出与自己一致/不一致的选择行为(实验2)时,其选择行为的一致性是如何影响结果评价过程的。脑电数据表明在结果评价的早期阶段,无论被试是主动或被动地与他人做出相同选择,这种选择一致性都会放大输赢结果之间的差异:体现在选择一致情况下比不一致情况下诱发更大的d FRN。而在结果评价的晚期阶段,当被试先做出选择之后,看到他人做出与自己不一致的选择时(实验2),相比他人与自己选择一致时,诱发了更大的P3和LPP波幅。说明被试很可能把他人的不一致选择加工为一种冲突。因此投入了更多认知资源来加工这一结果。本研究是一个探索性的创新研究,首次从时间维度上分离了选择行为和结果反馈两个阶段,并提供了选择一致性对结果评价有影响作用的脑电证据。     

Problematisations of Complexity: On the Notion and Production of Diverse Complexities in Healthcare Interventions and Evaluations

Within the literature on the evaluation of health (policy) interventions, complexity is a much-debated issue. In particular, many claim that so-called ‘complex interventions’ pose different challenges to evaluation studies than apparently ‘simple interventions’ do. Distinct ways of doing evaluation entail particular ontologies and epistemologies of complexity. They differ in terms of whether they define complexity as a quantitative trait of interventions, whether they see evaluation as part of or outside the intervention, and whether complexity can be regarded as an emergent property of the intervention and its evaluation. In practice, evaluators and commissioners of large health care improvement programmes rely on different, sometimes contradictory, repertoires about what it means to conduct a ‘good’ evaluation. This is an ongoing matter negotiated between and among commissioners, researchers, and—sometimes—programme managers. In particular, notions of evaluability, usefulness and distance/independence are problematised in different ways and with diverse consequences, which, in turn, produce other notions and layers of complexity such as temporal, institutional and affective complexities. When (social science) researchers claim that one method or another is better able to grasp complexity, they elide the issue that any methodological choice emphasises some complexities and lets others fade into the background. Analysing the practicalities and emotions involved in evaluation studies opens up the notion of complexity to analytical scrutiny, and suggests a basis for co-theorising between biomedical, public health and social scientists (including Science and Technology Studies scholars).     

The Effects of Repeated Exposure to the ARRAY Program With Offenders With Mental Illness

In an A‐B‐A‐B‐A single‐case research study of 3 incarcerated offenders with mental illness, repeated exposure to the pilot Adult Recidivism Reduction Alternatives (ARRAY) group counseling intervention was an effective or very effective treatment for anxiety, depression, and associated somatic symptoms.     

Development and validation of the REMINT: a reflection measure for individuals and teams

A growing number of studies have investigated the role of team reflexivity, the extent to which teams reflect on and adapt their functioning. However, the way team reflexivity has been conceptualized and operationalized reveals several weaknesses, in particular the conception as a unidimensional construct. To provide greater conceptual clarity, we therefore propose a team reflexivity framework that integrates four interacting but distinct reflexive processes. In four studies, we focus on reflection as a fundamental reflexive process, and develop and validate an extended multidimensional reflection measure that captures the relevant dimensions of quality and quantity of reflection and the key transition processes of information seeking and information evaluation. Moreover, in order to delineate two common composition methods, we develop and validate a direct consensus and a referent-shift consensus version of the reflection measure. Data collected from a total of 803 students and employees in four studies revealed excellent construct validity, as well as good nomological validity (Studies 1 and 2). Furthermore, we found evidence of the criterion-related validity at the team level (Study 3) and the individual level (Study 4). Together, the results demonstrate the effectiveness of our measure, revealing consistent relations with outcome measures and diverse behavioural indicators across different contexts.     

Exploring the role of sport in the development of substance addiction

PurposePotential benefits of participation in sport are widely known. However, sport participation has also been associated with risks, including consumption of alcohol and drugs and such risks may be enhanced among certain populations. The purpose of this study was to examine the possible links between participation in sport and the subsequent development of substance addiction.MethodRealistic Evaluation guided the study, with data collection occurring through semi-structured interviews. Interviews were conducted on a university campus or at a residential treatment center. The study included a total of 21 participants: 7 people who had between 3 and 29 years of sobriety, 13 people in a residential addiction treatment program, and 1 counselor.ResultsParticipants were grouped according to their sport backgrounds as 1) limited sport backgrounds, 2) recreational sports, 3) competitive athletes or 4) competitive athletes whose sport was terminated. Five main contexts were identified: 1) Familial History, Stability, and Illness, 2) Perceived Acceptability of Alcohol, 3) School and Social Atmosphere, 4) Sport Culture, Demands, and Expectations, and 5) Termination of Sport Involvement. The three main mechanisms were identified as: 1) Psychological Characteristics, 2) Coping Strategies, and 3) Availability of Substances.ConclusionsThe prevalence of substance abuse in sports settings might be under-represented in extant literature. The prevalence of substance abuse in sport contexts poses heightened risk of addiction for individuals who are already vulnerable for other reasons such as the presence of predisposing behaviors, psychological characteristics, or circumstances.     

An Empowerment Evaluation Model for Sexual Assault Programs: Empirical Evidence of Effectiveness

Using an empowerment evaluation approach, the Sexual Assault and Rape Prevention (SARP) Evaluation Project brought together university researchers, public health evaluators, state funders, and program staff to provide evaluation training and consultation to all state-funded rape prevention and victim services programs in Michigan. In this paper, the specific activities of the SARP project are described, and process and outcome data are presented that address the effectiveness of this empowerment evaluation approach. Based on subjective reports from program staff and objective data obtained from state funders, results suggest that this evaluation model was successful in helping 90% of the prevention programs and 75% of the victim services programs successfully develop and launch program evaluations. One-year follow-up data indicate that 90% of the programs had sustained their evaluation efforts after the formal work of the SARP project had ended.     

Social Class, Race, and Ethnicity: Career Interventions for Women Domestic Violence Survivors

This story describes a community intervention study conducted with women domestic violence survivors and a research dilemma related to the complex interrelationships between women's social class, race and ethnicity, and career development needs and experiences. The author presents diversity and research dilemmas related to facilitating women's critical consciousness of power dynamics at work in their lives. The influence of community context, career intervention curricula, and research team members' values on research decisions are described. This story highlights the importance of researchers examining their values and how those values impact the communities that they serve.     

Clinical and anatomical correlates of apraxia of speech

In a previous study (Dronkers, 1996), stroke patients identified as having apraxia of speech (AOS), an articulatory disorder, were found to have damage to the left superior precentral gyrus of the insula (SPGI). The present study sought (1) to characterize the performance of patients with AOS on a classic motor speech evaluation, and (2) to examine whether severity of AOS was influenced by the extent of the lesion. Videotaped speech evaluations of stroke patients with and without AOS were reviewed by two speech-language pathologists and independently scored. Results indicated that patients with AOS made the most errors on tasks requiring the coordination of complex, but not simple, articulatory movements. Patients scored lowest on the repetition of multisyllabic words and sentences that required immediate shifting between place and manner of articulation and rapid coordination of the lips, tongue, velum, and larynx. Last, all patients with AOS had lesions in the SPGI, whereas patients without apraxia of speech did not. Additional involvement of neighboring brain areas was associated with more severe forms of both AOS as well as language deficits, such as aphasia.     

E Contrario Reasoning: The Dilemma of the Silent Legislator

Summary This contribution offers an evaluation of e contrario reasoning in which the interpretation of a legal rule is based on the context of the law system (contextual e contrario reasoning). A model is presented which will show all the explicit and implicit elements of the argument at work and will also point out how these distinct parts are interrelated. By questioning the content and justificatory power of these elements, the weak spots in the argument can be laid bare. It will be argued that e contrario reasoning inevitably requires a dubious argumentative step, which renders the argument intrinsically weak. The model is applied to a European lawsuit on French cheese.
