The performance of Spanish-English bilinguals in two perception tasks, using a synthetic speech continuum varying in voice onset time, was compared with the performance of Spanish and English monolinguals. Voice onset time in speech production was also compared between these groups. Results in perception of bilinguals differed from that of both monolingual groups. Results of bilingual production in their two languages conformed with results obtained from each monolingual group. The perceptual results are interpreted in terms of differences in the use of available acoustic cues by bilingual and monolingual listeners of English and Spanish. 相似文献
Most personality tests are based on concepts assessing typical performance, and tests of this sort have not been generally successful in predicting criterion behaviors with useful levels of efficiency. Ability tests, which call for maximal performance, have been much more successful as predictors of criterion outcomes. Following a model derived from ability tests, predictors requiring separate typical and maximal self-reports of emotional expressivity were compared to measures of typical and maximal emotional expression in the laboratory. For angry expression, self-reports of maximal expressivity tended to outpredict self-reports of typical expressivity for both typical and maximal laboratory measures of angry expression. Although similar trends were observed for elation, the advantage of maximal self-report measures over typical self-report measures was negligible. Results were discussed in terms of both experimental and clinical implications. 相似文献
Two hypotheses concerning self-disclosure were investigated and confirmed in the present study, comparing homosexual and heterosexual college students. The first hypothesis was that self-disclosure, as measured by the Jourard Self-Disclosure Questionnaire, would be positively correlated with psychological femininity. The second hypothesis was that homosexual males and heterosexual females would exhibit similar patterns of high disclosure and femininity. No significant differences were found in total disclosure between homosexuals and heterosexuals, although homosexuals disclosed less to father, and more to friends than to parents. The conclusion was that psychological femininity and masculinity are more important than biological sex in determining self-disclosure. 相似文献
To investigate the timing of actions relative to events in the environment, we observed subjects leaping to punch a falling ball. We analysed their knee and elbow angles as functions of time for three ball-drop heights, finding that the differences in the functions for the different heights could be explained on the basis that the subjects were gearing their actions to a particular optic variable. This variable specifies the time remaining before contact with an object if the closing velocity is constant; for the falling ball it gives an increasingly accurate estimate of the time-to-contact. Our visuo-moto control model incorporates a delay parameter, the value of which was estimated from the data. In addition, correlations indicated that the knee and elbow were generally quite tightly coupled. The relationship of this task to laboratory tracking tasks and to the timing of actions in everyday life is described. 相似文献
Although patient intelligence may be an important determinant of the degree to which individuals may comprehend, comply with, and ultimately benefit from trauma-focused treatment, no prior studies have examined the impact of patient intelligence on benefit from psychotherapies for PTSD. We investigated the degree to which educational achievement, often used as a proxy for intelligence, and estimated full scale intelligence quotient (FSIQ) scores themselves moderated treatment outcomes for two effective psychotherapies for PTSD: Cognitive Processing Therapy (CPT) and Written Exposure Therapy (WET). Participants, 126 treatment-seeking adults with PTSD (52% male; mean age = 43.9, SD = 14.6), were equally randomized to CPT and WET; PTSD symptom severity was measured at baseline and 6-, 12-, 24-, 36-, and 60-weeks following the first treatment session. Multilevel models revealed that participants with higher FSIQ scores experienced significantly greater PTSD symptom reduction through the 24-week assessment in CPT but not WET; this effect did not persist through the 60-week assessment. Educational achievement did not moderate symptom change through either 24- or 60-weeks. Individuals with higher FSIQ who are treated with CPT may experience greater symptom improvement in the early stages of recovery. 相似文献
This systematic review aimed to examine sleep associations in a) typically developing children and their parents, and b) children with neurodevelopmental disorders and their parents. Literature search was conducted on PubMed, PsycINFO, EMBASE and Scopus databases for articles examining sleep associations between parents and children. Thirty studies were included in the final review. Based on the first aim, sleep associations between parents and typically developing children were observed for sleep quality, sleep duration and sleep efficiency. However, evidence for associations between sleepiness levels in parents and children and sleep schedules related to bedtime or waketime was limited. Based on the second aim, children with neurodevelopmental disorders and their parents reported greater sleep disturbances in comparison to typically developing children and their parents. The review concluded that sleep in parents and children is interrelated across a number of sleep parameters. It also revealed some preliminary evidence on bidirectionality in parent-child sleep, which warrants further examination. The review highlights the need to examine the mediating role of environmental factors on the interactions between parent-child sleep. Rigorous, longitudinal designs should be employed to explore the pathways through which parents may impact their children’s sleep and functioning and vice-versa.

Social skills are the basis of human interactions and functioning in society. Social competence (SC) is thought to evolve gradually during childhood and adolescence via the interplay of multiple factors. In particular, the early years of life are marked by the emergence of basic social abilities and constitute the foundation for successful social development. The biopsychosocial SOcio-Cognitive Integration of Abilities modeL (SOCIAL) posits that internal (child-based), external (environment), and cognitive factors are critical to SC in the context of normal brain maturation; but this has yet to be shown empirically and comprehensively. This study tested the SOCIAL model in a sample of typically developing preschool children. Parents of 103 children (M = 67.59 months, SD = 11.65) completed questionnaires and children underwent neuropsychological assessment of executive functioning (EF), communication skills and social cognition. Three-step hierarchical regression analyses (1) Internal factors, 2) External factors, 3) Cognitive factors) confirmed that each step of the regression model significantly predicted SC. In the final model, general cognitive and socio-cognitive factors significantly predicted SC above and beyond internal and external factors: children with lower temperamental negative affect and less parent-reported executive dysfunction, as well as better non-verbal communication and theory of mind had better SC. Our findings support the conceptual SOCIAL model, and highlight the importance of internal, external, and cognitive factors for SC in the preschool years. Identification of factors associated with early social development can inform both normative and clinical approaches to identifying intervention loci and optimizing SC in those at risk for maladaptive social functioning. 相似文献
