Children’s emergent language develops in a rich context of varied influences afforded by their familial and social environments. Using data collected during a longitudinal prospective service project, this study examined the direct and indirect contributions of parenting knowledge and practices and maternal postnatal depression on emergent language competencies of 198 very young children in high-risk Latino and African/American families in an urban area. The study used the Knowledge of Infant Development Inventory, a constructed measure of risky parenting practices for child well-health, home-safety, and corporal discipline, a constructed measure for children’s involvement in literacy oriented activities, Edinburgh Postnatal Depression Scale, and MacArthur Communicative Development Inventories to build and test a structural equation model with AMOS/SPSS 16. The results provide support for a mediated path model. Parenting knowledge and maternal postnatal depressive symptoms interacted directly and indirectly in influencing risky parental practices and children’s exposure in literacy oriented stimulation activities and emergent language. Children’s involvement in stimulation activities mediated the effects of parenting and maternal mental health and directly predicted a robust amount children’s emergent vocabulary. The model produced similar results for boys and girls, although boys had poorer outcomes. These findings provide empirical evidence that clinical practice and policy efforts are needed for reducing maternal postnatal depression in strengthening parenting efforts and in affording meaningful parent–child interactions and for assuring that children receive adequate exposure to activities that promote language development. Methodological limitations and recommendations for future research are addressed.  相似文献

This article deals with two well-documented phenomena regarding emotional stimuli: emotional memory enhancement—that is, better long-term memory for emotional than for neutral stimuli—and the emotion-induced recognition bias—that is, a more liberal response criterion for emotional than for neutral stimuli. Studies on visual emotion perception and attention suggest that emotion-related processes can be modulated by means of spatial-frequency filtering of the presented emotional stimuli. Specifically, low spatial frequencies are assumed to play a primary role for the influence of emotion on attention and judgment. Given this theoretical background, we investigated whether spatial-frequency filtering also impacts (1) the memory advantage for emotional faces and (2) the emotion-induced recognition bias, in a series of old/new recognition experiments. Participants completed incidental-learning tasks with high- (HSF) and low- (LSF) spatial-frequency-filtered emotional and neutral faces. The results of the surprise recognition tests showed a clear memory advantage for emotional stimuli. Most importantly, the emotional memory enhancement was significantly larger for face images containing only low-frequency information (LSF faces) than for HSF faces across all experiments, suggesting that LSF information plays a critical role in this effect, whereas the emotion-induced recognition bias was found only for HSF stimuli. We discuss our findings in terms of both the traditional account of different processing pathways for HSF and LSF information and a stimulus features account. The double dissociation in the results favors the latter account—that is, an explanation in terms of differences in the characteristics of HSF and LSF stimuli.  相似文献

Cultural issues tied to race/ethnicity are important aspects in delivering medical home services to children with neurodevelopmental disabilities and their families. To better understand family satisfaction with family centered care (FCC) in medical homes of children with disabilities, this study investigated whether family race/ethnicity, in addition to parent and child characteristics, significantly influenced family perceptions of FCC in three areas: family-provider partnership, care setting practices and policies, and community coordination and follow-up. Based on the life course theory for optimizing children's developmental trajectories, examining connections between family race/ethnicity and satisfaction with health care allows for identification of strengths and weaknesses in medical home services delivery, and offers opportunities for family support and improvement in outcomes for children with disabilities. This study developed an original empirical survey using a structured questionnaire developed by Family Voices, a national advocacy organization dedicated to promoting the well-being of children with disabilities and their families. The study collected data for 122 families in a large urban area in the northeastern United States. Multivariate analyses revealed that family race/ethnicity significantly contributed to the prediction of parental satisfaction with medical homes of children with disabilities, and to families' perceptions of FCC in care setting practices and policies, and community coordination and followup, but not to family provider partnership. Non-White families reported significantly lower satisfaction. Discussion emphasizes that health care providers need to become more vigilant in providing culturally sensitive care. To enhance FCC practices and policies, the study advances a checklist of ten essential areas that promote culturally sensitive interactions between families of children with disabilities and their medical and non-medical health care providers.  相似文献

Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are commonly comorbid, share genetic liability, and often exhibit overlapping cognitive impairments. Clarification of shared and distinct cognitive effects while considering comorbid symptoms across disorders has been lacking. In the current study, children ages 7–15 years assigned to three diagnostic groups:ADHD (n?=?509), ASD (n?=?97), and controls (n?=?301) completed measures spanning the cognitive domains of attention/arousal, working memory, set-shifting, inhibition, and response variability. Specific processes contributing to response variability were examined using a drift diffusion model, which separately quantified drift rate (i.e., efficiency of information processing), boundary separation (i.e., speed-accuracy trade-offs), and non-decision time. Children with ADHD and ASD were impaired on attention/arousal, processing speed, working memory, and response inhibition, but did not differ from controls on measures of delayed reward discounting, set-shifting, or interference control. Overall, impairments in the ASD group were not attributable to ADHD symptoms using either continuous symptom measures or latent categorical grouping approaches. Similarly, impairments in the ADHD group were not attributable to ASD symptoms. When specific RT parameters were considered, children with ADHD and ASD shared impairments in drift rate. However, children with ASD were uniquely characterized by a wider boundary separation. Findings suggest a combination of overlapping and unique patterns of cognitive impairment for children with ASD as compared to those with ADHD, particularly when the processes underlying reaction time measures are considered separately.  相似文献

Although previous research suggests that religion contributes to greater life satisfaction, there is still disagreement about what aspects of religion predict greater life satisfaction. Despite a growing body of theory and research on emerging adulthood as a life stage that is distinct from adolescence and young adulthood, there has also been limited research on the relationship between religion and life satisfaction among emerging adults. Based on the third wave of the National Study of Youth and Religion, our results suggest that two measures of private religiosity, private devotion and religious efficacy, are significantly related to greater life satisfaction among emerging adults. In contrast, other dimensions of private and public religiosity, such as participation in organised religion, religious salience, otherworldly beliefs, and number of religious friends, are not related to greater life satisfaction. Finally, among emerging adults, being spiritual but not religious is not significantly related to life satisfaction.  相似文献

Achievements in various fields of creativity are resulting more and more from collaborative teams. This research investigated the role of interpersonal process variables, namely closeness and perspective taking in group creativity, with a 2 by 2 experimental design. Sixty-one 3-person groups assigned to 4 conditions (a: closeness and perspective taking, b: perspective taking, c: no closeness and no perspective taking, d: closeness). Group members collaboratively wrote stories that were rated by 3 independent expert judges. There was a positive main effect of closeness and negative main effect of perspective taking on group creativity scores. Moreover, the significant interaction between perspective taking and closeness displayed that combination of closeness with perspective taking negatively affect group creativity. These results indicate that closeness might be beneficial for group creativity only when it is not accompanied with perspective taking.  相似文献

The present study sought to refine knowledge about the structure underlying externalizing dimensions. From a “top-down” ICD/DSM-based perspective, externalizing symptoms can be categorized into attention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). From a “bottom-up” developmental theory-based perspective, disruptive behaviors can be meaningfully described as aggressive (AGG) and rule-breaking (RB) behaviors. We analyzed five large data sets comprising externalizing symptom ratings obtained with a screening instrument using different sources (parents, teachers, self-ratings) from different samples. Using confirmatory factor analyses, we evaluated several factor models (unidimensional; correlated factors; bifactor (S-1) models) derived from an ICD/DSM- and theory-based perspective. Our optimally fitting models were assessed for measurement invariance across all sources, sample settings, and sex. Following several model-based criteria (model fit indices; factor loadings; omega statistics; model parsimony), we discarded our models stepwise and concluded that both the ICD/DSM-based model with three correlated factors (ADHD, ODD, CD) and the developmental theory-based model with three correlated factors (ADHD, AGG, RB) displayed a statistically sound factor structure and allowed for straightforward interpretability. Furthermore, these two models demonstrated metric invariance across all five samples and across sample settings (community, clinical), as well as scalar invariance across sources and sex. While the dimensions AGG and RB may depict a more empirically coherent view than the categorical perspective of ODD and CD, at this point we cannot clearly determine whether one perspective really outperforms the other. Implications for model selection according to our model-based criteria and clinical research are discussed.
