Prosodic information in the speech signal carries information about linguistic structure as well as emotional content. Although children are known to use prosodic information from infancy onward to assist linguistic decoding, the brain correlates of this skill in childhood have not yet been the subject of study. Brain activation associated with processing of linguistic prosody was examined in a study of 284 normally developing children between the ages of 5 and 18 years. Children listened to low-pass filtered sentences and were asked to detect those that matched a target sentence. fMRI scanning revealed multiple regions of activation that predicted behavioral performance, independent of age-related changes in activation. Likewise, age-related changes in task activation were found that were independent of differences in task accuracy. The overall pattern of activation is interpreted in light of task demands and factors that may underlie age-related changes in task performance. 相似文献

From a neuroconstructivist point of view based on infant cognitive development, the aim of this study is to get to know and compare the logical organization and content of the spontaneous activity of babies with alternative developmental courses (typical babies and Down's Syndrome ones). A fundamental form of logic is observed since the beginning of babies' interaction with their environment. This protologic is constructed through their organised and significative activity with the environment and it results in the elaboration of logico-mathematical and physical knowledge. Using Systematic Observation, we recorded the spontaneous activity of n=20 babies, (n=10 typical babies, n=10 Down Syndrome babies), with a cognitive developmental level of 1; 3 years (15 months). Microgenetical and statistical analyses were applied and the results obtained showed a reduced logical content and organization of the activity of Down's Syndrome babies, which corroborates and amplifies the results of previous research works. These results make evident the need to plan early educational intervention in order to optimize babies' developmental resources. 相似文献

The article reviews research on the problem of interrelationship between different physical and psychosocial factors in type 1 diabetes mellitus (DM1). The authors consider methodological principles of health-related quality of life (HRQoL) assessment in DM1 patients and stress the need for an integrated biopsychosocial approach to the management of the disease. DM1 is a chronic metabolic disease with an absolute requirement for insulin replacement therapy. The stress-inducing nature of DM1 is associated with its unexpected and dramatic manifestation in juvenile years, life-threatening nature of severe hypo-/hyperglycaemias and long-term complications, with the burden of diabetes self-management, threat of work disability, employment and career problems etc. These features of DM1 increase the likelihood of the development of anxiety and depressive disorders, which, in turn, may negatively influence the course of diabetes and in particular, diabetes self-care. This necessitates early diagnosis of emotional and behavioral disturbances in DM1 using self-report instruments as well as clinical assessment. Evidence suggests that active problem-focused coping behavior and adequate social support promote adherence to diabetes regimes and may act as a buffer against negative effects of the disease on HRQoL in DM1 patients. The core element in the HRQoL structure is personal disease picture (as opposed by objective clinical picture)--the cognitive-affective-behavioral complex reflecting the patient's personal perception of the disease. Examination of the personal disease picture and attitude towards the ailment in DM1 patients may help to improve understanding of the mechanisms of poor adjustment. Problems in disease adjustment can be detected also by diabetes-specific HRQoL assessment. The measures of HRQoL can be applied as screening instruments useful in increasing the effectiveness of patient-provider interactions and diabetes care. 相似文献

The Mood and Feelings Questionnaire (MFQ) is examined for its utility in screening youth in juvenile justice settings for depression. In a cross-sectional study conducted at King County Juvenile Detention Center, a representative sample of 228 detained adolescents complete structured assessments, including the MFQ and the Massachusetts Youth Screening Instrument. Fifty youth also complete the Voice-Diagnostic Interview Schedule for Children. Internal reliability coefficient for the MFQ short form (SMFQ) is = .87. Factor analysis produces a unifactorial scale with item loadings of .43 to .78. At SMFQ cutoff > or = 10, sensitivity and specificity are optimized at 1.00/0.79. Prevalence of major depressive disorder is estimated at 32.1% (95% Confidence Interval = 25.3% to 39.2%). The SMFQ shows potential for depression screening of detained adolescents. 相似文献

According to the contingent capture hypothesis, observers can specify their control settings in advance of the target’s presentation to quickly attend to relevant target colors. Two predictions were derived from this hypothesis and tested in a manual choice response task. First, contingent capture by color was expected: capture of spatial attention by a better-matching color stimulus should be stronger than capture by a less-matching color stimulus. Second, with the control settings specified in advance, the contingent capture by color should commence early after the stimulus onset and should be evident among fast correct responses in an RT distribution. Both predictions are shown to hold true in two experiments. Results are discussed in light of contrasting evidence for saccadic instead of manual responses. 相似文献

In this article, the authors argue that the overwhelming portion of the literature on intelligence, race, and genetics is based on folk taxonomies rather than scientific analysis. They suggest that because theorists of intelligence disagree as to what it is, any consideration of its relationships to other constructs must be tentative at best. They further argue that race is a social construction with no scientific definition. Thus, studies of the relationship between race and other constructs may serve social ends but cannot serve scientific ends. No gene has yet been conclusively linked to intelligence, so attempts to provide a compelling genetic link of race to intelligence are not feasible at this time. The authors also show that heritability, a behavior-genetic concept, is inadequate in regard to providing such a link. 相似文献

Still looking for Poppa 总被引:9,自引:0,他引:9
In 1992, V. Phares published an article titled "Where's Poppa?: The Relative Lack of Attention to the Role of Fathers in Child and Adolescent Psychopathology". Since that time, there have been modest gains in the research literature on clinical child issues, but there remains a wide gap between the inclusion of mothers and fathers in clinical child and family research. To provide an update of this issue for the field of developmental psychopathology, the authors of this comment conducted an updated review and analysis of the research on fathers and developmental psychopathology. These current data were compared with the data from the Phares and Compas (1992) study. It was found that there continues to be a dearth of research on fathers and developmental psychopathology. 相似文献

We performed a cross-sectional study with three age groups (8, 14, and 17 years) to evaluate developmental differences in stereotyped beliefs about physical attractiveness and the value of this as perceived by the participants. Given the current importance of television in the development of social knowledge, television models were used. The children and adolescents were asked to evaluate, using bipolar open scales, the physical attractiveness, likeableness, generosity, intelligence, fun, and altruism of 12 television models of both sexes, previously selected by judges, as well as the desire to resemble or feel close to the models. Analysis showed developmental differences across age groups both in the concept of physical attractiveness and in stereotyped beliefs about this. As in other areas of social knowledge, the younger children's responses were bipolar, global, and much more stereotyped, while the adolescents introduced subtle distinctions and elaborated their responses. Nevertheless, physical attractiveness appeared a desirable characteristic for all age groups. 相似文献

Three avian species, a seed-caching corvid (Clark's nutcrackers; Nucifraga columbiana), a non-seed-caching corvid (jackdaws; Corvus monedula), and a non-seed-caching columbid (pigeons; Columba livia), were tested for ability to learn to find a goal halfway between 2 landmarks when distance between the landmarks varied during training. All 3 species learned, but jackdaws took much longer than either pigeons or nutcrackers. The nutcrackers searched more accurately than either pigeons or jackdaws. Both nutcrackers and pigeons showed good transfer to novel landmark arrays in which interlandmark distances were novel, but inconclusive results were obtained from jackdaws. Species differences in this spatial task appear quantitative rather than qualitative and are associated with differences in natural history rather than phylogeny. 相似文献
