A qualitative analysis of young people's experiences of receiving a novel,client‐led,psychological therapy in school

Mental health problems often arise in adolescence. Schools have been recognised as a potential hub for support; however, delivering targeted interventions in schools can be difficult due to impracticalities. Subsequently, students have little or no say in the support process. Given the importance of control in well‐being, the current study explored how adolescents experienced Method of Levels, a therapy that allowed them to choose if and when to attend therapy. Interviews with 14 adolescents were conducted and then analysed using thematic analysis. Three main themes were identified; therapy style, therapy experience and exploring problems. An additional overarching theme was generated, regarding choice and control. Findings indicate that adolescents value having choice and control. This made the therapy style accessible, enhanced the therapeutic experience and ultimately facilitated the process of exploring problems.     

Being German,Paraguayan and Germanino: Exploring the Relation Between Social and Personal Identity

Despite people’s claims, their national, ethnic and other identities are not ubiquitously relevant, they are rather situationally evoked and performed. Such is the case with the German, Paraguayan and Germanino identity in the municipality of Nueva Germania, in Paraguay. Recognising such contextual epistemic permissibility allows us to form a de-essentialised understanding of groups and individuals. One of the challenges that emerge from this approach, is to understand how a person can perform different identities, which differently define who they are, while remaining certain of being a continuous and persistent person. The objective of this article is to provide a theoretical grounding for theories of social identity in theories of personal identity. It allows us to analytically accommodate the situational and multiscalar character of identities, while recognising their existential importance for personal identity (for the Self).     

颜色类别知觉效应的机制：语言的作用

颜色类别知觉效应(Category Perception, CP效应)表明, 在颜色之间物理差异距离相等的前提下, 个体区分不同类别的颜色比区分同一类别的颜色更快、更准确。这一效应产生的机制成为普遍进化理论和Sapir-Whorf假设之间争论的重要证据。支持CP效应由语言驱动的学者提出了CP效应单侧化、受语言即时任务影响、跨语言研究和神经生理机制等证据, 以表明语言在CP效应中起决定性的作用; 支持CP效应具有普遍性的学者以CP效应双侧化、婴儿的CP效应、跨语言的反证等证据提出了质疑。近年来, 出现了第三种观点, 认为在颜色CP效应中语言驱动机制和普遍机制并存, 这种理论是普遍进化理论和Whorf假设的折衷观点。从支持CP效应由语言驱动的证据、支持CP效应独立于语言的证据以及支持两种机制并存的观点等三个方面入手, 可分析颜色CP效应的产生机制及语言在其中所起的作用, 未来研究可从概念系统渗入知觉系统的角度进行拓展。     

Drivers discuss ecodriving feedback: Goal setting,framing, and anchoring motivate new behaviors

Ecodriving, defined here as the adoption of energy efficient driving styles and practices (primarily moderating accelerations and decelerations, reducing top speeds, and improved maintenance practices), has long been recognized as a potential source of reductions in transportation energy use. Estimates of energy savings attributed to ecodriving range widely, from less than 5% to as high as 20% depending on the driving and experimental context. To explore the effects on ecodriving of interaction between drivers and in-vehicle energy feedback, a customized, interactive energy feedback interface was deployed in a field test with real-world drivers. This paper presents the results of interviews with 46 Plug-in Hybrid Electric Vehicle (PHEV) drivers who were given the ecodriving feedback interface for a multi-week trial including an interface off (baseline) and on (treatment) condition. This paper relies specifically on self-reports of driver motivations and behaviors to better understand what types of information motivated new ecodriving behavior; a future paper will investigate quantitative fuel consumption effects. Driver interviews at the conclusion of the study revealed that the introduction of feedback led three fourths of drivers to change driving styles to maximize on-road efficiency, at least in the short term. In addition, this study finds that the context of the feedback information, provided by a built-in goal or other contextualizing information such as a comparison value, is important for both comprehension and motivation. Personalization of the information allowed different drivers to access pertinent information, increasing the motivational value of the information. Instantaneous performance feedback such as real-time energy economy or power is used primarily for experimentation and learning of new ecodriving behaviors, whereas average performance feedback is used primarily for goal-setting and goal achievement. In addition, the direct comparison of personalized driver goals and average performance created a game-like experience that encouraged high achievement. Finally, the driver interviews revealed that feedback frames driving as a time to act in an efficient manner.     

Towards consensus in conceptualizing and operationalizing physical activity maintenance

Recognized challenges in promoting long-term physical activity maintenance may be due to inconsistencies in the conceptualization and operationalization of behavior maintenance terminology in physical activity research. The overall goal of this paper is to propose a framework and agenda for the development of a common set of terms, definitions, and measures for physical activity maintenance concepts that can be widely tested and evaluated. To initiate this effort, this paper (1) provides an overview of conceptual and operational definitions of physical activity maintenance used in the empirical literature, (2) evaluates whether behavior maintenance terms used in addiction science can be translated to physical activity, (3) recommends research directions for developing consensus definitions of physical activity maintenance, and (4) proposes a conceptual model of physical activity maintenance with inflection points that require operational definitions to be decided upon through consensus efforts in the field. Consensus over the conceptualization and operationalization of physical activity maintenance is needed to draw conclusions regarding which policies and programs are best able to promote long-term behavior change.     

Theistic Ethics and the Euthyphro Dilemma

It is widely believed that the Divine Command Theory is untenable due to the Euthyphro Dilemma. This article first examines the Platonic dialogue of that name, and shows that Socrates's reasoning is faulty. Second, the dilemma in the form in which many contemporary philosophers accept it is examined in detail, and this reasoning is also shown to be deficient. This is not to say, however, that the Divine Command Theory is true—merely that one popular argument for rejecting it is unsound. Finally some brief thoughts are presented concerning where the real problems lie for the theory.     

Factorial structure of the ‘ToM Storybooks’: A test evaluating multiple components of Theory of Mind

This study examined the factorial structure of the Theory of Mind (ToM) Storybooks, a comprehensive 93‐item instrument tapping the five components in Wellman's model of ToM (emotion recognition, understanding of desire and beliefs, ability to distinguish between physical and mental entities, and awareness of the link between perception and knowledge). A sample of 681 three‐ to eight‐year‐old Italian children was divided into three age groups to assess whether factorial structure varied across different age ranges. Partial credit model analysis was applied to the data, leading to the empirical identification of 23 composite variables aggregating the ToM Storybooks items. Confirmatory factor analysis was then conducted on the composite variables, providing support for the theoretical model. There were partial differences in the specific composite variables making up the dimensions for each of the three age groups. A single test evaluating distinct dimensions of ToM is a valuable resource for clinical practice which may be used to define differential profiles for specific populations.
