Development of a vocabulary of object shapes in a child with a very-early-acquired visual agnosia: A unique case

We report a longitudinal study of an exceptional child (S.R.) whose early-acquired visual agnosia, following encephalitis at 8 weeks of age, did not prevent her from learning to construct an increasing vocabulary of visual object forms (drawn from different categories), albeit slowly. S.R. had problems perceiving subtle differences in shape; she was unable to segment local letters within global displays; and she would bring complex scenes close to her eyes: a symptom suggestive of an attempt to reduce visual crowding. Investigations revealed a robust ability to use the gestalt grouping factors of proximity and collinearity to detect fragmented forms in noisy backgrounds, compared with a very weak ability to segment fragmented forms on the basis of contrasts of shape. When contrasts in spatial grouping and shape were pitted against each other, shape made little contribution, consistent with problems in perceiving complex scenes, but when shape contrast was varied, and spatial grouping was held constant, S.R. showed the same hierarchy of difficulty as the controls, although her responses were slowed. This is the first report of a child's visual–perceptual development following very early neurological impairments to the visual cortex. Her ability to learn to perceive visual shape following damage at a rudimentary stage of perceptual development contrasts starkly with the loss of such ability in childhood cases of acquired visual agnosia that follow damage to the established perceptual system. Clearly, there is a critical period during which neurological damage to the highly active, early developing visual–perceptual system does not prevent but only impairs further learning.     

Additive factors and stages of mental processes in task networks

To perform a task a subject executes mental processes. An experimental manipulation, such as a change in stimulus intensity, is said to selectively influence a process if it changes the duration of that process leaving other process durations unchanged. For random process durations a definition of a factor selectively influencing a process by increments is given in terms of stochastic dominance (also called “the usual stochastic order”). A technique for analyzing reaction times, Sternberg’s Additive Factor Method, assumes all the processes are in series. When all processes are in series, each process is called a stage. With the Additive Factor Method, if two experimental factors selectively influence two different stages by increments, the factors will have additive effects on reaction time. An assumption of the Additive Factor Method is that if two experimental factors interact, then they influence the same stage. We consider sets of processes in which some pairs of processes are sequential and some are concurrent (i.e., the processes are partially ordered). We propose a natural definition of a stage for such sets of processes. For partially ordered processes, with our definition of a stage, if two experimental factors selectively influence two different processes by increments, each within a different stage, then the factors have additive effects. If each process selectively influenced by increments is in the same stage, then an interaction is possible, although not inevitable.     

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.     

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.

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.     

Development and test of a model of interdisciplinary competencies

Interdisciplinary work offers both innovative potential and challenges in collaboration. The present paper summarizes three studies intended to foster a psychological, competency-focused understanding of interdisciplinary work. In a qualitative interview study (Study 1) with expert practitioners of interdisciplinarity, we used the critical incident technique to explore which individual competencies support interdisciplinary collaborations and improve innovative outcomes. Focusing on competencies specific to interdisciplinarity, we derived a four-dimensional model. In Study 2, we tested the model dimensions (1) initiative for exchange, (2) target group-specific communication, (3) knowledge integration, and (4) reflection in a quantitative survey study among N = 315 employees who were experienced in interdisciplinary work using exploratory structural equation modelling. Finally, in Study 3, we studied the convergent and divergent validity of interdisciplinary competencies as well as their role in predicting team outcomes. Here, a dyadic sample of N = 448 target persons and N = 153 interdisciplinary colleagues were surveyed. We discuss possible applications for the new model of interdisciplinary competencies and the developed self-report instrument.
