Metacognitive components of writing: Construction and validation of the Metacognitive Components of Planning Writing Self-inventory (MCPW-I)

IntroductionWriting and metacognition play an essential function in the learning process, in that writers engage arduous cognitive efforts by selecting and organizing ideas, then reviewing and readjusting them.ObjectiveThe present research aimed to construct and validate a self-report instrument to measure some specific metacognitive processes implicated in writing planning. Two categories of metacognitive components were considered: metacognitive knowledge and self-regulation strategies.MethodBased on exploratory and confirmatory analyses, the Metacognitive Components of Planning Writing Self-inventory (MCPW-I) was constructed and validated. This instrument is composed of three factors: Metacognitive Conditional Knowledge – MCK (6 items), Covert Self-regulation – CSF (4 items), and Environmental self-regulation – ESF (5 items). 1022 undergraduates students engaged in various programs of a French university filled in the inventory.ResultsThe alpha coefficients indicated a reliable internal consistency and the test-retest reliability showed a good temporal stability. Correlational analyses revealed that the CRS factor was related to ESR and MCK factors, and these last two were not correlated with each other. After the analysis of variance, the responses relative to ESR and MCK dimensions differed according to gender, but no differences relatively to the academic disciplines considered was found. Concerning the predictive validity, CSF and MCK were correlated with writing performance.ConclusionThe results confirm the validity and reliability of the MCPW-I which constitutes a new research tool for the study of metacognitive processes of writing.     

Investigating route learning,metacognition, and beacon-based strategies using virtual environments

IntroductionDominant theories of wayfinding may have underestimated the ease with which adults can learn a route, even with minimal exposure to that route.ObjectivesIn this paper we present three different experiments to provide a comprehensive picture of whether adults can learn complex routes consisting of a number of choicepoints, and if so, what strategies they might be employing to do so.Methodand results We found that adults could learn a 15-junction route after only a single experience of the route (Experiment 1) but that they underestimated how good they would be at learning the 15-junction route (Experiment 2). In Experiment 3, we found that when learning a route made up of “T” shaped junctions, participants relied on a “beacon” strategy based on visual matching.ConclusionsCollectively, these findings suggest that adults can learn complex routes, even with as many as 15 choicepoints, very quickly and without the need for repeated exposure. These findings have implications for theories of wayfinding and call into question the need for repeated exposure.     

Personal values and unsanctioned aggression inherent in contact sports: The role of self-regulatory mechanisms,aggressiveness, and demographic variables

IntroductionTo date, research-examining factors related to the sociocognitive self-regulatory mechanisms governing unsanctioned aggression have received scant attention in applied sport psychology.ObjectiveA mediating model as influenced by various demographic variables was applied to explore the relationships between athletes’ personal values and their unsanctioned aggression directly and indirectly through the mediating role of resistive self-regulatory efficacy, moral disengagement, and aggressiveness.MethodA sample of 301 French competitors of different age (young: n = 200 and adult: n = 101), gender (male: n = 172 and female: n = 129), type of sport (high: n = 131 and low contact: n = 170), level of competition (beginner: n = 115, intermediate: n = 110, and advanced: n = 76), and length of practice (brief: n = 109, intermediate: n = 49, and extensive: n = 143) completed a questionnaire assessing the aforementioned variables.ResultsStructural equation modelling demonstrates that self-transcendence and self-enhancement values have only indirect negative and positive effects, respectively, on unsanctioned aggression through the full mediating effect of the mediators. Also, age, gender, and type of sport were predictive only of some personal values and mediators.ConclusionThese findings offer evidence that resistive self-regulatory efficacy, moral disengagement, and aggressiveness are mediators that fully govern the impact of athletes’ personal values and certain demographic variables on their unsanctioned aggression. Several limitations, implications and suggestions for further research are discussed.     

演绎推理的形式和内容启动加工

聚焦推理加工初期,研究通过指导语操控主观加工倾向,考察不同指导语条件下内容可信度和形式有效性对演绎推理结果的影响,检验内容和形式两类加工过程的启动加工动态变化性。结果表明,指导语条件显著影响推理初期加工。在无提示指导语和形式判定指导语条件下,推理结果受到了形式有效性和内容可信度的影响;内容判定指导语下只受到了内容可信度的影响。证明主观加工倾向影响了内容和形式的启动加工关系,支持了动态变化性的假设。     

Neuronal changes in normal human aging and Alzheimer's disease

This article discusses age-related changes in brain weight, total number of cortical neurons, cortical dendrites, spine, and synapse density. The conclusion is that the present outlook is less grim than it was 30 years ago. Age-related reduction appears to be specific to brain region and cortical layer rather than a general feature. In addition, we describe a different pattern of changes that occur in Alzheimer's disease patients. This review concludes that the association cortices in particular are affected in aging and Alzheimer's disease and that the primary visual and somatosensory cortices are relatively spared.     

Ethical dilemmas in testing for late onset conditions: reactions to testing and perceived impact on other family members

This paper examines some of the ethical dilemmas that arise when testing for the late onset, untreatable condition of Huntington disease (HD) specifically now that technology allows us to test younger generations of the family for the mutant gene. Drawing on interview data from families with Huntington disease, the reactions to testing and perceived impact on other family members are considered. These are discussed in the light of the possible lowering of the age of test applicants. This potentially raises problems for a younger generation as they are confronted with reproductive decisions that the older generation did not have to face. It also means that individuals have the prospect of living with knowledge of a future illness for much longer.     

Fabry disease in genetic counseling practice: recommendations of the National Society of Genetic Counselors

The objective of this document is to provide health care professionals with recommendations for genetic counseling and testing of individuals with a suspected or confirmed diagnosis of Fabry disease, with a family history of Fabry disease, and those identified as female carriers of Fabry disease. These recommendations are the opinions of a multicenter working group of genetic counselors, medical geneticists, and other health professionals with expertise in Fabry disease counseling, as well as an individual with Fabry disease who is a founder of a Fabry disease patient advocacy group in the United States. The recommendations are U.S. Preventive Task Force Class III, and they are based on clinical experience, a review of pertinent English-language articles, and reports of expert committees. This document reviews the genetics of Fabry disease, the indications for genetic testing and interpretation of results, psychosocial considerations, and references for professional and patient resources. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. The professional judgment of a healthcare provider, familiar with the facts and circumstances of a specific case, will always supersede these recommendations.     

Traumatic Brain Injury as a Risk Factor for Alzheimer's Disease: A Review

Accumulating epidemiological evidence implicates traumatic brain injury as a pathogenic agent in the development of Alzheimer's disease (AD). Considering the increase in the prevalence of both traumatic brain injury and AD in recent times, the possibility that brain trauma may provoke the early development of AD has important implications for health service planning, preventative efforts, and medico-legal compensation settlements. This paper evaluates the plausibility of the proposed link between traumatic brain injury and AD, largely by way of exploring a theoretical perspective advanced by Satz (1993) and considering recent contributions from the epidemiological, neuropathological, and biochemical literature that are pertinent to this issue. The literature reviewed provides sufficient support and empirical vindication to give credence to the proposed association between these two neuropsychological entities at the statistical, theoretical, and biological level.     

A Pathological View of Disease

This paper is a response to Christopher Boorse's recent defense of hisBiostatistical Theory (BST) of health and disease. Boorse maintains that hisconcept of theoretical health and disease reflects the ``consideredusage of pathologists.' I argue that pathologists do not use ``disease' inthe purely theoretical way that is required by the BST. Pathology does notdraw a sharp distinction between theoretical and practical aspects ofmedicine. Pathology does not even need a theoretical concept of disease. Itsfocus is not theoretical, but practical; pathology's goal is to contribute tothe healing of patients. Pathology, even experimental pathology, is notvalue-free. Not only ``disease' but also such terms as ``nerve' and ``organ'are laden with conceptual values.     

Managing one's body using self-management techniques: practicing autonomy

This paper discusses some of the anthropological andphilosophical features of the use of self-managementplans by patients with a chronic disease, focusing onpatients with asthma. Characteristics of thistechnologically mediated form of self-care arecontrasted with the work of Mauss and Foucault on bodytechniques and techniques of self. The similaritiesand differences between self-management of asthma andFoucault's technologies of self highlight some of theways in which self-management contributes tomodifications in the definitions of patients andphysicians. Patients, in measuring their lungfunction, first come to rely on measurements more thanon felt disturbances, but next, felt disturbancesbecome modified by previous measurements. Physicians,on the other hand, see their role changed from expertto being a participant in a joint treatment. It isargued that the concept of agency is more appropriatefor describing the advantage of self-management forpatients than autonomy.
