Speech perception of four phonetic categories (voicing, place, manner, and nasality) was investigated in children with specific language impairment (SLI) (n = 20) and age-matched controls (n = 19) in quiet and various noise conditions using an AXB two-alternative forced-choice paradigm. Children with SLI exhibited robust speech perception deficits in silence, stationary noise, and amplitude-modulated noise. Comparable deficits were obtained for fast, intermediate, and slow modulation rates, and this speaks against the various temporal processing accounts of SLI. Children with SLI exhibited normal “masking release” effects (i.e., better performance in fluctuating noise than in stationary noise), again suggesting relatively spared spectral and temporal auditory resolution. In terms of phonetic categories, voicing was more affected than place, manner, or nasality. The specific nature of this voicing deficit is hard to explain with general processing impairments in attention or memory. Finally, speech perception in noise correlated with an oral language component but not with either a memory or IQ component, and it accounted for unique variance beyond IQ and low-level auditory perception. In sum, poor speech perception seems to be one of the primary deficits in children with SLI that might explain poor phonological development, impaired word production, and poor word comprehension. 相似文献

As US demographic trends shift toward more diversity, it becomes increasingly necessary to address differential needs of diverse groups of youth in mental health service systems. Cultural and linguistic competence (CLC) is essential to providing the most appropriate mental health services to youth and their families. The successful implementation of CLC often begins at the system level. Though various factors may affect change and system-level factors set the tone for broad acceptance of CLC within systems, there is limited empirical evidence linking culturally competent practices to outcomes. The purpose of the present study was to examine system-level CLC changes over time within systems of care and their associations with service experiences among youth and their families. Participants were 4,512 youth and their families enrolled in the national evaluation of the Children’s Mental Health Initiative (CMHI). Results suggest that implementation of CLC at the system level improves over time in funded systems of care. Further, variation exists in specific system-level components of CLC. In addition, the changes in CLC at the system level are related to family/caregiver participation in treatment. Implications for supporting positive changes in CLC among systems of care communities, and specific strategies for community psychologists, are discussed. 相似文献

This study describes development in federally funded systems of care. Data for this study were collected using the System of Care Assessment that rated grantees' enactment of system of care principles in the infrastructure and service delivery domains. Data were collected by trained raters who conducted several site visits over the funding period. This study described system development over time across 61 sites and tested whether gains were statistically significant. Latent profile analysis was used to explore whether sites could be meaningfully grouped based on their baseline service delivery domain scores. Differences across groups were tested in terms of community, system, and client characteristics. Differential growth across groups was also examined. Overall, systems of care developed over time in both the infrastructure and service delivery domains. Although infrastructure scores were generally lower than service delivery scores, greater gains were seen for the infrastructure domain. Three groups of sites were identified that could be distinguished in terms of degree of development overall, and for specific system of care principles. The groups of sites differed in terms of community factors, system features, and client characteristics. In addition, repeated measures analyses found differential growth in system development over time across groups. 相似文献

The stress associated with providing care for a spouse diagnosed with Alzheimer's disease can have adverse effects on cardiovascular health. One potential explanation is that chronic caregiving stress may contribute to the development of atherosclerosis. The purpose of this study was to determine whether the duration that one has provided care is associated with the degree of atherosclerotic burden, as measured by carotid artery intima-media thickness (IMT). One hundred and ten Alzheimer caregivers [mean age 74?±?8 (SD) years, 69% female] underwent in-home assessment of carotid artery IMT via B-mode ultrasonography. Data regarding medical history, blood pressure, and multiple indicators of caregiving stress were also collected. Multiple regression indicated that duration of care was positively associated with IMT measured in the internal/bifurcation segments of the carotid artery (β?=?0.202, p?=?0.044) independent of risk factors such as age, gender, body mass index, smoking history, sleep quality, hypertension status, and caregiving stressors. Duration of care was positively associated with IMT in the common carotid artery, but the relationship was not significant. These findings provide more evidence of the link between chronic caregiving stress and cardiovascular disease and indicate that enduring the experience of caregiving over a period of years might be associated with atherosclerotic burden. 相似文献

ABSTRACT: Thirty hospitalized suicidal adolescents were compared with thirty-four hospitalized nonsuicidal teenagers and thirty-five nonhospitalized coping youngsters (controls) on the extent of their problems, their perceptions of peer and family relationships, degree of hopelessness, and locus of control. Suicidals were found to experience the greatest total number of problems, nonsuicidals the next most, and controls the fewest. Significantly more peer problems differentiated the suicidals from the other two groups, while serious family problems discriminated the three groups from each other. The controls viewed their families as the most well-adjusted, followed by the nonsuicidals, while the suicidals felt their families were the most maladjusted. Suicide attempters experienced a significantly greater degree of hopelessness than all the nonattempters, and significantly more external locus of control than the controls. Some sex differences emerged in the study. 相似文献
