Analysis of the spontaneous speech of eight stuttering and eight normally fluent children reveals that (a) the location of both stuttering and normal disfluent moments is constrained by sentential constituent structure, and (b) stuttering children experience fluency breakdown with a particular type of constituent (verb phrase) not usually disfluently produced by normals. A view of early stuttering as a sentence planning and integration disorder is present.  相似文献

A modified form of Nathanson and Becker's (1983) Health Belief Model Questionnaire and other measures designed to assess cognitive processing were administered to low-income black adolescent female clients of an inner-city comprehensive health care clinic. The purpose of the study was to explore determinants of sexual activity and contraceptive use. Subjects were classified as not sexually active (n = 50), sexually active/noncontracepting (n = 20), or sexually active/contracepting (n = 72). Not sexually active subjects tended to be younger, more career motivated, to have a father at home, to be more influenced by family values, and to have more conservative attitudes regarding adolescent sexuality than did sexually active subjects. Sexually active/noncontracepting subjects tended to report fewer benefits and more barriers to the use of contraception. Level of cognitive processing did not differ among the three groups, but was at a lower-than-expected level for age. Finally, inconsistent contraceptive use was common to both sexually active groups.  相似文献

A recent theoretical model of centrality (Bernstein, 1987; Bernstein, Hofmann, Santiago, & Diebolt, 1989) suggests that the importance attached to certain “central issues” may increase the vulnerability of individuals to distress and depression, and may explain the differential rates of depression among gender, racial, and ethnic groups. The present study was designed to examine the importance of central issues as reported by Anglo, Black, and Hispanic men and women (N=169). Multivariate analyses revealed significant gender, ethnicity, and gender X ethnicity effects. Specifically, women considered Intimacy significantly more important than did men, whereas men attached more importance than women to Affiliation. Anglos rated Achievement significantly higher than did Hispanics and Blacks; Hispanics considered Affiliation more important than the other two groups; and Blacks considered Intimacy the least important among the groups. Moreover, Hispanic men attributed significantly greater importance to Change, Adventure, and Control, whereas Hispanic women attached the least significance among all the groups to Control. The results are discussed in terms of cultural influences on sex role orientation and central issues, and the process by which culture and ethnicity may be related to vulnerability to depression and distress.  相似文献

The factorial validity and internal consistency reliability of the Devereux Elementary School Behavior Rating Scale was examined using a random sample of elementary-school children in grades I through 6. Teacher ratings of subjects' classroom behaviors on the Devereux approximated ratings obtained by the standardization sample. Internal consistency (coefficient alpha) reliability coefficients of the 11 Devereux subscales were found to be quite adequate, ranging from 80 to 93. Intercorrelations among Devereux subscales were moderate to high. A principal factor analysis of the 11 subscales produced two factors with eigenvalues greater than 1.0, which cumulatively accounted for 70.2% of the total variance. When rotated via an orthogonal (Varimax) solution, the two resultant factors appeared to measure emotional adjustment and academic related dimensions of classroom behavior. Given the problem of multicollinearity that was shown to exist among subscales, the authors suggest caution in the interpretation of Devereux subscales as discrete factors.The authors gratefully acknowledge computer support funding provided by the University of Wisconsin, Graduate School Research Committee Grant 135-1537 to the first author.  相似文献

Emerging adults are at substantial risk for developing or worsening psychopathology and university students appear to be particularly vulnerable. Interventions targeted at these young adults that can mitigate transdiagnostic causal risk factors or burgeoning mental health problems have the potential to make a large impact. We aimed to develop and pilot test an accessible, single-session, transdiagnostic group intervention with the goals of enhancing emotion regulation skills and reducing risk for mental health problems in graduate students. The intervention included psychoeducation, skills instruction (e.g., mindful emotion awareness, cognitive flexibility, countering emotion-driven behaviors), group discussion, and supervised practice based on content from the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders. The pilot program demonstrated strong feasibility and acceptability. Baseline, 1-month, and 3-month follow-up surveys also suggested benefits for reducing emotional avoidance and suppression, increasing use of cognitive reappraisal, and reducing symptoms of depression and neuroticism. Graduate students have seldom been the beneficiaries of university-based intervention and prevention research. Furthermore, most college and university mental health centers do not have the capacity to provide psychoeducation, preventative, or early intervention services to the many students who need or could benefit from them. Results suggest that future iterations of this intervention could address such barriers to meaningfully supporting emerging adults in graduate school.  相似文献

Age-related differences in brain activity mediating face recognition were examined using positron emission tomography. Participants encoded faces using a pleasant-unpleasant judgment, a right-left orientation task, and intentional learning. Scans also were obtained during recognition. Both young and old groups showed signficant effects of encoding task on recognition accuracy, but older adults showed reduced accuracy overall. Increased brain activity in older adults was similar to that seen in young adults during conditions associated with deeper processing, but was reduced during the shallow encoding and recognition conditions. Left prefrontal activity was less in older adults during encoding, but greater during recognition. Differential correlations of brain activity and behavior were found that suggest older adults use unique neural systems to facilitate face memory.  相似文献

Speech perception without hearing   总被引:6,自引:0,他引:6  
In this study of visual phonetic speech perception without accompanying auditory speech stimuli, adults with normal hearing (NH; n = 96) and with severely to profoundly impaired hearing (IH; n = 72) identified consonant-vowel (CV) nonsense syllables and words in isolation and in sentences. The measures of phonetic perception were the proportion of phonemes correct and the proportion of transmitted feature information for CVs, the proportion of phonemes correct for words, and the proportion of phonemes correct and the amount of phoneme substitution entropy for sentences. The results demonstrated greater sensitivity to phonetic information in the IH group. Transmitted feature information was related to isolated word scores for the IH group, but not for the NH group. Phoneme errors in sentences were more systematic in the IH than in the NH group. Individual differences in phonetic perception for CVs were more highly associated with word and sentence performance for the IH than for the NH group. The results suggest that the necessity to perceive speech without hearing can be associated with enhanced visual phonetic perception in some individuals.  相似文献

Taxometric coherent cut kinetic analyses were used to test the latent structure of anxiety sensitivity (AS) among 371 youth. Anxiety sensitivity was indexed by the 18-item Childhood Anxiety Sensitivity Index (CASI; Silverman et al., J. Clin. Child Psychol. (1991), 20, 162-168). Two sets of manifest indicators of AS were constructed using the CASI: (1) three item-parcel manifest indicators: disease concerns, unsteady concerns, and mental illness concerns; and (2) nine single-item indicators representing each of these three facets of AS. Results from standard and short-scale MAXCOV procedures, internal consistency tests, analyses of simulated Monte Carlo data, and MAMBAC external consistency tests indicated that the latent structure of anxiety sensitivity among youth was taxonic. Estimated base rate of the observed AS taxon ranged between 13.6 and 16.5%. The present findings are discussed in terms of theoretical implications for the study of AS and vulnerability for anxiety psychopathology.  相似文献

We used behavioral and emotional problem items to construct (a) nosologically based Diagnostic and Statistical Manual of Mental Disorders (DSM) oriented scales from experts' ratings of the items' consistency with DSM-IV (4th ed.; American Psychiatric Association, 1994) diagnostic categories, and (b) statistically based syndromes from factor analyses of adults' self-ratings and ratings of adults by people who knew them (N = 4,628). Quantified, operationally defined, and normed DSM-oriented scales and statistically based syndromes facilitate multitaxonomic approaches to the assessment of adult psychopathology. Psychometric properties and cross-informant correlations were similar for DSM-oriented scales and statistically derived syndromes. Statistical associations between phenotypically similar DSM-oriented scales and statistically based syndromes were moderate to strong. Multitaxonomic approaches can avoid reification of provisional taxa that may result from excessive reliance on a single taxonomic paradigm.  相似文献
