Autistic spectrum disorder (ASD) is diagnosed on the basis of impairment in reciprocal social interaction and language, and rigidity of behavior. This brief paper describes the development of an experimental intervention for preschool children newly diagnosed with ASD. The rationale for this intervention is the hypothesis that failure to attend to social cues in very early life, of itself, may bear a large share of responsibility for core social and communicative deficits. The intervention, therefore, uses eye-tracking to monitor and trigger rewards for attention to facial expression and direction of gaze. 相似文献

Prior research has demonstrated that race, at least to some extent, is related to employment decisions such as selection and performance appraisals. However, little prior research has addressed the impact of race on employment termination. The current study investigates whether race is related to employment termination and highlights the importance of education, an important component of human capital, in understanding racial differences in termination. Results based on 548 employees from a large hotel chain indicate that race is related to termination; however, race is not predictive of termination when education is included in the regression analysis as a predictor. These findings support the notion that a societal level variable (i.e., education) is an important factor in reducing racial inequality in employment practices. 相似文献
The current research investigated age and gender stereotypes in relation to adaptive performance. Using methods similar to those used in Schein's studies (1973, 1975) , 496 undergraduate students rated 1 of 7 targets on 6 dimensions of adaptive performance. All of the targets varied in age (25, 40, or 55 years) and gender, except one that was age and gender neutral. The 7th served as a reference group and was an age- and gender-neutral target. Results showed that older targets were perceived as less adaptable across most of the dimensions of adaptability. Further, men and women were perceived differently, but differences were consistent with many prevalent gender stereotypes. Finally, female participants tended to rate all targets more favorably than male participants. Implications for human resources management and future research on stereotypes at work are discussed. 相似文献
Based on a sample of 275 Chinese poor families in Hong Kong, the influence of parental expectations of children’s future and adolescents’ perceived parental control on adolescent well-being (cognitive competence and self-identity) was examined. Consistent with our hypotheses, the results indicated that parental expectations of children’s future and adolescents’ perceived parental control directly influenced adolescent cognitive competence and self-identity. Furthermore, adolescent perceived maternal control moderated the influence of paternal expectations on cognitive competence and self-identity among Chinese adolescents. Simple slope analyses showed that paternal expectations influenced adolescent cognitive competence and self-identity under low levels of perceived maternal control than did high levels of perceived maternal control. The present study underscores the dynamic nature of the influence of parental expectations and perceived parental control on adolescent well-being (cognitive competence and self-identity) in poor Chinese families.
We report on a study of the influence of aging pathways on the evolution of solute-rich features in peak-aged Al-Mg-Si-Cu alloys. The concentration and partitioning ratios of Mg, Si and Cu and Mg/Si ratios in the heterogeneous solute-rich features all increase with increasing size, with Si exhibiting the highest partitioning ratio, but notably these ratios change dramatically depending on the aging pathway selected. Accordingly, the short-time age hardening response can be enhanced by promoting both homogeneous and heterogeneous precipitate nucleation, while simultaneous improvements in peak-aged strength and elongation can be attained by a vacancy-assisted aging pathway. 相似文献

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk. 相似文献
This article explores attachment relationships from a network theory perspective: Correlations among behaviors, beliefs, and feelings related to attachment are hypothesized to stem from causal relations. The authors used two data sets that assessed relationships with four attachment figures (mother, father, romantic partner, and best friend) using the Relationship Structures Questionnaire. Separate networks (Gaussian Graphical Models) were estimated based on 10 items for each attachment figure. Across networks in Study 1 (N = 310), items related to anxiety, seeking support, and discomfort disclosing feelings clustered with other items from their respective domains; a trust‐related item bridged the clusters. Study 2 replicated these findings in a larger and more diverse sample (N = 3,710). The potential of network analysis for advancing the study of attachment is discussed. 相似文献
