Two cohorts of children and adolescents (who started 6th grade in 1993 and 1996), parents, teachers, and peers participated in a 4-wave, 2-year, longitudinal study of perceived competence and depressive symptoms. The authors assessed children's tendencies to underestimate their competence (discrepant self-appraisals) relative to the appraisals of significant others. We also assessed the degree to which self-appraisals reflected the evaluations of others (reflective self-appraisals). Domains of competence were academic competence, physical appearance, behavioral conduct, social acceptance, and athletic competence. Cross-sectional analyses indicated that depressive symptoms correlated with reflective and discrepant self-appraisals. Longitudinal analyses revealed that reflective and discrepant self-appraisals predicted subsequent depressive symptoms and that depressive symptoms predicted discrepant but not reflective self-appraisals. Clinical implications of the findings are discussed. 相似文献

Validated the interrelatedness of depression and anxiety in young children by testing four latent factor models: dual construct, unrelated; dual construct, correlated; single construct; and second-order or higher order analysis to test that depression and anxiety are primary constructs under the higher order factor of general affective distress. Children (N = 86) were ages 6 to 11, with mothers who were HIV-symptomatic or diagnosed with AIDS. Depression and anxiety measures included the Children's Depression Inventory (Kovacs, 1992), selected items from the Dominic-R (Valla, Bergeron, Berube, Gaudet, & St-Georges, 1994), and the Revised Children's Manifest Anxiety Scale (Reynolds & Richmond, 1985). Structural equation modeling was used to test the models. Model 2 (dual construct, correlated) fit the data better than did Models 1 and 3; results for the higher order model were identical to Model 2, suggesting the higher order model is equivalent to the dual-construct model. 相似文献

The purpose of this study was to examine differences between children who do (CWS) and children who do not stutter (CWNS) on standardized tests of receptive/expressive language and receptive vocabulary. Subjects were 16 boys and 4 girls who stutter (mean age = 46.80 months) and 16 boys and 4 girls who do not stutter (mean age = 47.55 months). Each child was audio recorded during a loosely structured, 30-minute conversation with an adult. This conversational interaction was subsequently assessed to provide information pertinent to the child's frequency and type of speech disfluency. After completion of the adult-child conversational interaction, each child was administered and responded to standardized tests of syntactic, semantic, and phonological abilities and development. Results indicated that the difference between measures of receptive/expressive language and receptive vocabulary is significantly greater for CWS than CWNS; however, this difference between receptive/expressive language and receptive vocabulary scores was not significantly correlated with the overall stuttering frequency of CWS. Findings were taken to suggest that the semantic development of CWS may lag behind their syntactic development, a possible imbalance among components of the speech-language systems of CWS that may contribute to the difficulties they have establishing normal speech fluency.

Color-from-motion displays consist of a sparse array of dots which never move but change color according to various algorithms. Yet such displays can trigger human vision to construct apparent motion of a subjective surface which is uniformly colored and bounded by a subjective contour. We show that the perceptual strength of this construction depends on the density and regularity of dot placement. We studied three objective measures of density and regularity: nearest-neighbor distance, mean of maximal disks, and variance of maximal disks. We found that nearest-neighbor mechanisms alone are inadequate to account for the perceptual strength of the subjective surfaces and contours. Mechanisms sensitive to areal gaps provide a more adequate account. 相似文献

This study investigated how global personality traits and teasing history are related to participants' emotional and behavioral reactions to an actual teasing event. College undergraduates (N = 108) worked on a task with a same-sex confederate. While interacting, the confederate either teased participants about how slowly they were working on the task or made a benign comment about the nature of the task. Analyses revealed that even mild teasing can generate negativity towards the teaser and interaction. More interestingly, however, personality moderated reactions to teasing, as teasing condition interacted with each of the Big Five personality domains in theoretically meaningful ways. Childhood teasing history also moderated reactions to teasing, as frequent victims and frequent teasers responded in different ways. 相似文献

Protection of human subjects from investigators' conflicts of interest is critical to the integrity of clinical investigation. Personal financial conflicts of interest are addressed by university policies, professional society guidelines, public standards, and government regulation, but "intrinsic conflict of interest"--conflicts of interest inherent in all clinical research--have received relatively less attention. Such conflicts arise in all clinical research endeavors as a result of the tension among professionals' responsibilities to their research and to their patients and both academic and financial incentives. These conflicts should be disclosed to research subjects and managed as assiduously as are financial conflicts of interest. 相似文献

This pilot study concerned the intelligibility of accented speech for listeners of different ages. 72 native speakers of English, representing three age groups (20-39, 40-59, 60 and older) listened to words and sentences produced by native speakers of English, Taiwanese, and Spanish. Listeners transcribed words and sentences. Listeners also rated speakers' comprehensibility, i.e., listeners' perceptions of difficulty in understanding utterances, and accentedness, i.e., how strong a speaker's foreign accent is perceived to be. On intelligibility measures, older adults had significantly greater difficulty in understanding individuals with accented speech than the other two age groups. Listeners, regardless of age, were more likely to provide correct responses if they perceived the speaker easier to understand. Ratings of comprehensibility were highly correlated with ratings of accentedness. 相似文献

The first goal of this study was to investigate sociometric status, aggression, and gender differences in children's verbalizations and cheating behavior during game playing using a fine-grained observational coding system. The second goal was to control for the effects of differential peer treatment and bias on children's behavior by observing children in a standardized procedure with unfamiliar peer confederates. Participants were 111 second-grade African American children, half average and half rejected sociometric status, half aggressive and half nonaggressive based on peer nominations, and half boys and half girls. Rejected children engaged in more cheating behavior and made more negative and argumentative verbalizations than average status children. Boys made more negative and argumentative verbalizations than girls. Aggressive children did not differ from nonaggressive children, in terms of either verbalizations or cheating behavior. 相似文献
