Conflict partners and infrastructure use in safety critical events in cycling – Results from a naturalistic cycling study

Accident statistics show that cyclists are at considerable risk of being involved in a crash. However, statistics based on police reports are often heavily biased towards on-road, bicycle–motor vehicle crashes. Crashes that do not involve motorised vehicles or that occur on other types of infrastructure are neglected. Naturalistic cycling methodology appears to be a promising approach to address these issues. The goal of this study was to identify and classify safety critical cycling events involving a variety of conflict partners and covering all types of infrastructure. Thirty-one participants in three age groups had their own bicycles equipped with a data acquisition system. Participants rode their modified bike as usual for a period of four weeks. Over 1600 trips were recorded overall. We were able to identify 77 safety critical events during the observation period. Only 43% of these events involved motorised vehicles as conflict partners. Conflicts with other cyclists and pedestrians accounted for about 57% of the situations. Likewise, less than 35% of the events occurred on-road. The data show that although motorised vehicles are still the single biggest threat to cycling safety, and roads still constitute one of the most crash prone types of infrastructure, the importance of crashes that do not involve motorised road users or occur not on-road should not be underestimated.     

The Educational Psychology of Self-Regulation: A Conceptual and Critical Analysis

The multiplicity of definitions and conceptions of self-regulation that typifies contemporary research on self-regulation in psychology and educational psychology is examined. This examination is followed by critical analyses of theory and research in educational psychology that reveal not only conceptual confusions, but misunderstandings of conceptual versus empirical issues, individualistic biases to the detriment of an adequate consideration of social and cultural contexts, and a tendency to reify psychological states and processes as ontologically foundational to self-regulation. The essay concludes with a consideration of educational research and intervention in the area of students’ self-regulated learning in terms of the scientific and professional interests of psychologists and educators, and the disguised manipulation of student self-surveillance in the service of the institutional mandates of schools.     

The Pragma-Dialectical Analysis and Evaluation of Teleological Argumentation in a Legal Context

In this article the author develops a framework for a pragma-dialectical reconstruction of teleological argumentation in a legal context. Ideas taken from legal theory are integrated in a pragma-dialectical model for analyzing and evaluating argumentation, thus providing a more systematic and elaborate framework for assessing the quality of teleological arguments in a legal context. Teleological argumentation in a legal context is approached as a specific form of pragmatic argumentation. The legal criteria that are relevant for the evaluation of teleological argumentation are discussed and translated in terms of critical questions that are relevant for the evaluation of the various forms of teleological argumentation.

Navigating Critical Theory and Postmodernism: Social Justice and Therapist Power in Family Therapy

The family therapy field encourages commitment to diversity and social justice, but offers varying ideas about how to attentively consider these issues. Critical informed models advocate activism, whereas postmodern informed models encourage multiple perspectives. It is often not clear how activism and an emphasis on multiple perspectives connect, engendering the sense that critical and postmodern practices may be disparate. To understand how therapists negotiate these perspectives in practice, this qualitative grounded theory analysis drew on interviews with 11 therapists, each known for their work from both critical and postmodern perspectives. We found that these therapists generally engage in a set of shared constructionist practices while also demonstrating two distinct forms of activism: activism through countering and activism through collaborating. Ultimately, decisions made about how to navigate critical and postmodern influences were connected to how therapists viewed ethics and the ways they were comfortable using their therapeutic power. The findings illustrate practice strategies through which therapists apply each approach.     

Critical thinking ability and belief in the paranormal

A study was conducted to assess the relationship between critical thinking and belief in the paranormal. 180 students from three departments (psychology, arts, computer science) completed one measure of reasoning, the Paranormal Belief Scale (Tobacyk & Milford, 1983), and a scale of paranormal experiences. Half of the subjects filled out the Cornell Critical Thinking Test (Ennis & Millmann, 1985) and the Watson–Glaser Critical Thinking Appraisal (Watson & Glaser, 2002), respectively. The results show no significant correlations between critical thinking and paranormal belief or experiences. Reasoning ability, however, had a significant effect on paranormal belief scores, but not on paranormal experiences. Subjects with lower reasoning ability scored higher on Traditional Paranormal Belief and New Age Philosophy than did subjects with higher reasoning abilities. Results suggest that those who have better reasoning abilities scrutinise to a greater extent whether their experiences are sufficient justification for belief in the reality of these phenomena.     

论道德继承

道德是符合社会之理而维持社会存在的人的行为价值和规范。道德有一般与特殊之分,一般道德的抽象性和特殊道德的具体性决定了二者继承方法的选择,即前者抽象继承,后者批判继承。历史上积累的道德价值和道德规范是道德继承的对象,此对象无论采取何种表述方式,终究可以用语言或者文字的形式表述为一个道德命题。因此,道德继承实质上是对道德命题的继承。道德命题是以善恶价值为内容、对某一道德状况或某一道德要求用逻辑语言所作的判断和陈述。它通常包括形式的或者逻辑的层面和实际的或者经验的层面,前者表征其一般意义,后者表征其特殊意义。理论上,前者采用抽象继承法,后者采用批判继承法,但实际上二者密不可分。因此,现实生活中的道德继承需兼顾两面,即采用一体两面相结合的道德继承模式。     

Determining who to question, what to ask, and how much information to ask for: the development of inquiry in young children

To obtain reliable information, it is important to identify and effectively question knowledgeable informants. Two experiments examined how age and the ease of distinguishing between reliable and unreliable sources influence children’s ability to effectively question those sources to solve problems. A sample of 3- to 5-year-olds was introduced to a knowledgeable informant contrasted with an informant who always gave inaccurate answers or one who always indicated ignorance. Children were generally better at determining which informant to question when a knowledgeable informant was contrasted with an ignorant informant than when a knowledgeable informant was contrasted with an inaccurate informant. In some cases, age also influenced the ability to determine who to question and what to ask. Importantly, in both experiments, the strongest predictor of accuracy was whether children had acquired sufficient information; successful problem solving required integrating knowledge of who to question, what to ask, and how much information to ask for.     

Old dogs learning new tricks: Neuroplasticity beyond the juvenile period

Twenty years ago, the prevalent view in Psychology was that although learning and the formation of new memories are lifelong occurrences, the neural changes associated with these events were all in the existing receptors. No new neural hardware, from synapses to neurons, was thought to appear after a protracted period early in life. In the past 20 years, another view has supplanted this one, showing that although the juvenile period is especially suited to neuroplastic adaptation, there is hard neuroplastic change later in life as well. We review a selection of evidence for this view from both animal and human models, showing how it reflects three principles of neuroplasticity: (1) earlier and later experience-induced changes to neuroarchitecture differ in degree more so than in type; (2) the types of experiences that lead to neuroplastic change narrow with age; and (3) differences in the amenability of neural circuitry to change result from basic differences in neuroarchitecture and neuroenvironment in different phases of development.     

试论批判性思维与逻辑的关系

“批判性思维”一词已成为当今教育界一个十分时髦的术语。心理学家、教育学家、哲学家都在讨论批判性思维。但是,什么是批判性思维?其逻辑基础是什么呢?我们认为,目前学界对此的认识有待进一步澄清。在逻辑学界,批判性思维已成为当前逻辑学教学改革和发展的一种重要方向。有学者认为,批判性思维与非形式逻辑有着密不可分的联系,甚至有人认为批判性思维与非形式逻辑两者可以不加区别交互使用。该文首先考察了心理学家、教育学家和哲学家们分别给出的批判性思维的定义,然后分析批判性思维与非形式逻辑、形式逻辑之间的相互联系与区别,进而认为形式逻辑和非形式逻辑共同构成了批判性思维的逻辑基础。     

Scaling affordances for human reach actions

A methodology developed by Cesari and Newell [Cesari, P., & Newell, K. M. (1999). The scaling of human grip configuration. Journal of Experimental Psychology: Human Perception and Performance 25, 927-935; Cesari, P., & Newell, K. M. (2000). The body-scaling of grip configurations in children aged 6-12 years. Developmental Psychobiology 36, 301-310] was used to delineate the roles of an object's weight (W) and distance (D) as well as the actor's strength (S) in determining the macroscopic action used to reach for the object. Participants reached for objects of five different weights placed at 10 distances. The findings of a single discriminant analysis revealed that when object weight is scaled in terms of each individual's strength and reach distance is scaled in terms of each individual's maximum-seated reach distance, a single discriminant analysis was able to predict 90% of the reach modes used by both men and women. The result of the discriminant analysis was used to construct a body-scaled equation, K=lnD+ln(W/S)/36, similar in form to the one derived by Cesari and Newell, accurately predicted the reach action used. Our findings indicate that Cesari and Newell's method can identify a complex relationship between geometric and dynamic constraints that determine the affordances for different reach actions.
