The relationship between anxiety and depression was examined in a sample of 106 children and adolescents referred to an outpatient anxiety disorder clinic for children. Twenty-eight percent of patients with DSM-III diagnoses of anxiety disorders displayed a concurrent major depression. Children with anxiety disorders plus major depression were found (1) to be older, (2) to demonstrate more severe anxiety symptomatology, and (3) to be diagnosed with different rates of certain anxiety-disorder subtypes, when compared to anxious patients without major depression. Nondepressed anxious children and adolescents did not differ from a psychopathological control group in severity of either anxiety or depression symptoms. 相似文献

Differences between a clinical sample of younger (ages 5 to 11) and older (ages 12 to 19) children meeting DSM-III criteria for overanxious disorder (OAD) were examined. Younger and older children were compared in terms of (1) the rates of OAD diagnoses occurring in the two age groups, (2) sociodemographic characteristics, (3) symptom expression, (4) association with other forms of maladjustment, and (5) self-reported anxiety and depression. The prevalence of OAD diagnoses and sociodemographic characteristics did not differ. Although younger and older OAD children showed similar rates of most specific DSM-III OAD symptoms, older children presented with a higher total number of overanxious symptoms than younger children. Older children more frequently exhibited a concurrent major depression or simple phobia, whereas younger OAD children more commonly had coexisting separation anxiety or attention deficit disorders. Older OAD children reported significantly higher levels of anxiety and depression on self-report measures. Findings indicated that the expression of OAD varies by developmental level. 相似文献

This paper re-examines two hypotheses on the ontogeny of hemispheric specialization that long ago fell into disfavor in neuropsychology. It is argued that these hypotheses, equipotentiality and progressive lateralization, may have suffered from misinterpretation that fostered premature acceptance of the developmental invariance view of hemispheric specialization. An alternative view is presented that incorporates both hypotheses within a neurodevelopmental context using anatomical (postmortem) and childhood aphasia data. 相似文献

Cross-sectional differences and longitudinal changes in cognitive functioning in relation to mortality across a 7-year follow-up period, with 3 times of measurement, were examined in a population-based sample of very old adults. The authors also sought to determine whether cause of death (cerebro/cardiovascular disease [CVD]; non-CVD) modified the magnitude of mortality-related cognitive deficits. Cognitive performance was indexed by tests of general cognitive ability, episodic memory, primary memory, verbal fluency, and visuospatial ability. Results indicated cross-sectional differences on all domains of functioning, with persons who would die within 3 years after baseline testing performing more poorly. Longitudinally, greater decrements were observed on all domains for persons who would die after the first follow-up period, as compared with survivors. Cause of death failed to modify the magnitude of the cross-sectional and longitudinal deficits. The pattern of results point to the general nature of this phenomenon. 相似文献

Five competing models specifying the factor structure underlying the Wechsler Memory Scale-Third Edition (D. Wechsler, 1997b) primary subtest scores were evaluated in a sample of patients with intractable temporal lobe epilepsy (N = 254). Models specifying separate immediate and delayed constructs resulted in inadmissible parameter estimates and model specification error. There were negligible goodness-of-fit differences between a 3-factor model of working memory, auditory memory, and visual memory and a nested--more parsimonious--2-factor model of working memory and general memory. The results suggest that specifying a separate visual memory factor provides little advantage for this sample--an unexpected finding in a population with lateralized dysfunction, for which one might have predicted separate auditory and visual memory dimensions. 相似文献

Orientation and navigation in a complex environment requires path planning and recall to exert goal-driven behavior. Walking Drosophila flies possess a visual orientation memory for attractive targets which is localized in the central complex of the adult brain. Here we show that this type of working memory requires the cGMP-dependent protein kinase encoded by the foraging gene in just one type of ellipsoid-body ring neurons. Moreover, genetic and epistatic interaction studies provide evidence that Foraging functions upstream of the Ignorant Ribosomal-S6 Kinase 2, thus revealing a novel neuronal signaling pathway necessary for this type of memory in Drosophila. 相似文献

The goals of the present study were to assess the interrelationships among tasks from the MATRICS and CNTRACS batteries, to determine the degree to which tasks from each battery capture unique variance in cognitive dysfunction in schizophrenia, and to determine the ability of tasks from each battery to predict functional outcome. Subjects were 104 schizophrenia patients and 132 healthy control subjects recruited as part of the CNTRACS initiative. All subjects completed four CNTRACS tasks and two tasks from the MATRICS battery: Brief Assessment of Cognition in Schizophrenia Symbol Coding and the Hopkins Verbal Learning Test. Functional outcome was also assessed in the schizophrenia subjects. In both the patient and control groups, we found significant intercorrelations between all higher order cognitive tasks (episodic memory, goal maintenance, processing speed, verbal learning) but minimal relationships with the visual task. For almost all tasks, scores were significantly related to measures of functional outcome, with higher associations between CNTRACS tasks and performance-based measures of function and between one of the MATRICS tasks and self-reported functioning, relative to the other functioning measures. After regressing out variance shared by other tasks, we continued to observe group differences in performance among task residuals, particularly for measures of episodic memory from both batteries, although these residuals did not correlate as robustly with functional outcome as raw test scores. These findings suggest that there exists both shared and specific variance across cognitive tasks related to cognitive and functional impairments in schizophrenia and that measures derived from cognitive neuroscience can predict functional capacity and status in schizophrenia. 相似文献

This prospective study investigated the personal growth of Israeli mothers of premature babies at two medically defined risk levels (infants at low risk, n = 42; infants at moderate-high risk, n = 52), examining the contribution to the five dimensions of personal growth of objective event characteristics (baby’s risk level), perceived levels of mother’s stress (linear and curvilinear associations), and mother’s personal resources (self-esteem, attachment styles, perceived emotional support from her own mother). In addition, the role of the event severity as a moderator of the association between perceived maternal emotional support and personal growth was explored. Findings indicate that mothers in the two risk groups did not differ in level of perceived stress. Mothers of infants at moderate-high risk, however, experienced more spiritual change. In addition, consistent curvilinear associations emerged between perceived levels of stress and personal growth for three dimensions of growth: new possibilities, personal strength, and relations with others (with a similar trend for appreciation of life). Thus, mothers reporting moderate stress levels experienced the highest personal growth. Finally, risk group played a moderating role in the association between perceived maternal emotional support and personal growth on the dimensions of new possibilities, personal strength, and relations with others. On these dimensions, only among mothers of low-risk babies were higher levels of maternal emotional support associated with greater personal growth. The results highlight the importance of the subjective experience and the value of maternal emotional support for the personal growth of mothers of preterms. These findings may help in designing measures to identify populations at risk and developing appropriate interventions, as well as impact on the working procedures and support currently offered in most neonatal intensive care units. 相似文献

This study was conducted for three purposes. First, we assessed the development of children's concepts of hardness as an intensive physical quantity. We hypothesized a U-shaped behavioral growth curve for children's judgments on tasks measuring intensive physical quantity, but the hypothesis was not confirmed. The justifications accompanying correct and incorrect judgments for hardness were similar to those where U-shaped behavioral growth was found for other intensive physical quantities (temperature and sweetness). The second purpose was to determine how children solve seriation and transitivity tasks where hardness was the content. More older than younger children solved these tasks, and the transitivity task was correctly solved after the seriation task was correctly solved. One pattern of solutions for transitivity and intensive physical quantity allowed for differentiation between younger and older children who solved the intensivity tasks correctly. The third purpose was to determine whether children think that objects' hardnesses are labile (i.e., hard objects can become soft and vice versa) by simply adding more of that substance. More younger than older children thought that this was true 相似文献
