Cognitive neuropsychology provides a theoretical framework and methods that can be of value in the study of developmental disorders, but the "dissociation" logic at the centre of this approach is not well suited to the developmental context. This is illustrated with examples from specific language impairment. Within the developing language system there is ample evidence for interaction between levels of representation, with modularity emerging in the course of development. This means that one typically is seeking to explain a complex pattern of associated impairments, rather than highly selective deficits. For instance, a selective impairment in auditory processing can have repercussions through the language system and may lead to distinctive syntactic deficits that are seen in written as well as spoken language. Changes in the nature of representations and in the relationships between components of a developing system mean that cross-sectional data at a single point in development may be misleading indicators of the primary deficit. Furthermore, traditional cognitive neuropsychology places a disproportionate emphasis on representational (competence) deficits, with processing (performance) deficits being relatively neglected. Methods for distinguishing these two kinds of impairment are discussed, as well as other approaches for elucidating the underlying nature of developmental disorders.  相似文献

Advances in the treatment of the human immunodeficiency virus (HIV) have dramatically improved survival rates over the past 10 years, but HIV-associated neurocognitive disorders (HAND) remain highly prevalent and continue to represent a significant public health problem. This review provides an update on the nature, extent, and diagnosis of HAND. Particular emphasis is placed on critically evaluating research within the realm of cognitive neuropsychology that aims to elucidate the component processes of HAND across the domains of executive functions, motor skills, speeded information processing, episodic memory, attention/working memory, language, and visuoperception. In addition to clarifying the cognitive mechanisms of HAND (e.g., impaired cognitive control), the cognitive neuropsychology approach may enhance the ecological validity of neuroAIDS research and inform the development of much needed novel, targeted cognitive and behavioral therapies. The research described was supported by MH73419 and MH62512 from the National Institutes of Health. The views expressed in this article are those of the authors and do not reflect the official policy or position of the Department of the Navy, Department of Defense, nor the United States Government.  相似文献

Although there are compelling theoretical explications linking performance on the Wechsler Adult Intelligence Scale (WAIS) with specific nosological groups, research findings have been inconsistent in demonstrating such relations. Three shortcomings can be identified within this literature: (a) it focuses mostly on the WAIS, (b) it relies on pre-Diagnostic and Statistical Manual of Mental Disorders (3rd ed. [DSM-III], American Psychiatric Association, 1980) criteria, and (c) it employs transformed scares or composite indices of WAIS performance. This article attempts to link performance variability on the WAIS-R (Revised) with diagnostic membership. The hypotheses of Rapaport, Gill, and Schafer (1968) are used to evaluate the clinical significance of the resulting discriminant equation.  相似文献

This article reports the authors' observations on 22 families in which a young adult member has been diagnosed as manic-depressive, and on 11 families in which a member has been diagnosed as suffering from major schizoaffective disorder. All families could be described as extremely rigid and bound-up systems. Many of them were characterized by a "restrictive parental complementarity" and reciprocal delegation, and they shared certain cognitive features and assumptions. "Manic-depressive" families showed similarities as well as differences when compared with families in which there were schizophrenic and serious psychosomatic disorders.  相似文献

Measures of parental affective style of communication, based on direct family discussions, were obtained for a sample of 52 families of disturbed but nonpsychotic adolescents. When the variations of both parents on the measure for two different measurement contexts were combined, an accurate prediction of subsequent psychiatric status at follow-up occurred. Adolescents with at least one parent who consistently displayed a pathological affective style of communication in both a dyadic and triadic discussion developed schizophrenia-spectrum disorders as young adults. Conversely, adolescents with at least one parent who was consistently benign in affective style had healthier outcomes. Finally, more serious young adult psychopathology was noted where both parents were inconsistent in their affective style from dyadic to triadic interaction. Methodological implications for family interaction research are discussed.  相似文献

German psychologists may have been first to establish a university curriculum in psychology with the expressed purpose to provide—after its successful completion—a certificate of professional qualification. This Diplom-Prüfungsordnung (Diploma Examination Regulation) was accepted nationwide in 1941. However, it took over fifty more years before some progress toward the political and legal acceptance of autonomous clinical activities of psychologists was made. Legislation to secure these advances is still pending. In this context the efforts to establish the profession of clinical neuropsychology are described and discussed within the historical development of professional psychology in Germany with special emphasis on the problems of compromises within the force fields of science and professional politics. Finally, the postgraduate training as well as the certification and accreditation procedures developed by the Gesellschaft für Neuropsychologie, the Society of German-speaking neuropsychologists, are presented.  相似文献

Children showing a comorbid behavior pattern of hyperactivity-impulsivity-inattention and conduct problems (HIA + CP) were contrasted to children having only an internalizing and externalizing behavior pattern (I + E) and matched controls. Children displaying the HIA + CP behavior pattern were at greater risk on a number of outcome measures in social and academic domains beginning in Grade 3 and continuing into Grade 4. The most marked differences among the three groups were found on peer measures of rejection and friendship and teacher ratings of social skills. On average, almost two-thirds of the HIA + CP group were rejected by their peers compared to one-third of the I + E group and only 12.5% controls. Over 70% of the HIA + CP group had no reciprocated friendships from Grade 3 to Grade 4 compared to less than half of the I + E group and approximately one-fourth of controls. Contrary to much theorizing in the literature, the HIA + CP and I + E groups showed average levels of academic self-concept and did not differ from controls in on measures of social self-concept and academic self-concept and general self-esteem. These findings were interpreted in light of positive illusory biases and the established link between aggressive behavior and egotism. The current article offers partial support for Lynam's (1996) notion of the fledgling psychopath.  相似文献

This study is a follow-up to a prior publication by the authors dealing with influences behind neutral responses to structured questionnaires. The earlier study found rater affective feelings, nationality, and age to be significant influences, while sex was not. The questionnaire used in the first study dealt primarily with supervision and relied on a three-point scale. The present instrument covers a broader range of topics and uses a five-point Likert-type scale. The results on the influence of rater affective feelings are consistent with previous studies, but there is some variation in the demographic influences. Implications of the findings are discussed and suggestions are offered for additional research.  相似文献

Physical trauma to the brain has always been known to affect brain functions and subsequent neurobiological development. Research primarily since the early 1990s has shown that psychological trauma can have detrimental effects on brain function that are not only lasting but that may alter patterns of subsequent neurodevelopment, particularly in children although developmental effects may be seen in adults as well. Childhood trauma produces a diverse range of symptoms and defining the brain's response to trauma and the factors that mediate the body's stress response systems is at the forefront of scientific investigation. This paper reviews the current evidence relating psychological trauma to anatomical and functional changes in the brain and discusses the need for accurate diagnosis and treatment to minimize such effects and to recognize their existence in developing treatment programs.  相似文献

100 children from the north-east of England, aged between 7 and 13 years of age, completed an assessment of intellectual ability and an attention battery based on the work of Mirsky, Anthony, Duncan, Ahearn, & Kellam (1991). Factor analysis was generally supportive of the Mirsky et al. (1991) model. Replication of the adult model produced the same four factors: sustain, encode, focus-execute and shift. Replication of the child model produced a three-factor model in which the encode and focus-execute factors combined. An extended model resulted in the introduction of a new factor labelled errors of processing. The scores on attention factors were found to have a reasonable level of independence from intellectual ability.  相似文献

The role of beliefs, personality variables, and demographic factors in the sentencing of juvenile offenders was investigated. The subjects (1,030 members of the juvenile justice system) judged hypothetical juvenile perpetrators. Various personality, belief, and demographic variables were found to be related to sentencing severity; these relationships differed based on the type of crime judged. Further, relations among these variables and sentencing behavior indicated three coherent patterns or resonances. A liberal group of individuals, believing in rehabilitation, external causality of crime, a positive prognosis for the perpetrator, and nontraditional views of women, sentenced moderately. Two types of conservative individuals were defined. Both groups were punitive, and believed in internal causality of crime; however, they differed on attitudes toward women, needs for cognition, and beliefs about seriousness and harm. One group sentenced the most severely and the other the most leniently. Implications for the sentencing of juvenile offenders are discussed.  相似文献

The present study investigated how demographic, personality, and climate variables act to predict departmental theft. Participants in the current field survey were 153 employees from 17 departments across two stores. The results of confirmatory factor analyses supported the construct validity of the Big Five Inventory (John, Donahue, & Kentle, 1991) and the Occupational Climate Questionnaire (Furnham & Gunter, 1997) in UK work settings. The results of regression analysis indicate that the variability in departmental theft is accountable in terms of a linear combination of demographic, personality, and climate factors. We concluded that an expanded theoretical perspective (utilizing demographic, personality, and climate variables) explained more variance than might otherwise be expected from any single perspective. Indeed, climate, personality, and demographic variables operated legitimately at the departmental level. Finally, we explained aggregated personality as a form of social interaction which is the by-product of individual differences.  相似文献

A neurobiological account of cognitive vulnerability for recurrent depression is presented based on recent developments of resting state neural networks. We propose that alterations in the interplay between task positive (TP) and task negative (TN) elements of the Default Mode Network (DMN) act as a neurobiological risk factor for recurrent depression mediated by cognitive mechanisms. In the framework, depression is characterized by an imbalance between TN-TP components leading to an overpowering of TP by TN activity. The TN-TP imbalance is associated with a dysfunctional internally-focused cognitive style as well as a failure to attenuate TN activity in the transition from rest to task. Thus we propose the TN-TP imbalance as overarching neural mechanism involved in crucial cognitive risk factors for recurrent depression, namely rumination, impaired attentional control, and cognitive reactivity. During remission the TN-TP imbalance persists predisposing to vulnerability of recurrent depression. Empirical data to support this model is reviewed. Finally, we specify how this framework can guide future research efforts.  相似文献
