Family-level factors that characterize the home environment are critical inputs to early language and cognitive development, and potential mechanisms for improving developmental outcomes in vulnerable populations. Many studies conducted in high-income and Western settings highlight stimulating parenting, the home language environment, and parental self-efficacy as possible mechanisms of early development, though less is known about how these family-level factors impact child development in low- or middle-income settings. Even less is known about these family-level factors and early childhood development in rural China, where rates of cognitive and language delay in children aged 0–3 years are as high as 45% and 46%, respectively. Using data collected from 77 rural households with children aged 18–24 months in Southwestern China, this study examines the associations between stimulating parenting, the home language environment, and parental self-efficacy, and early cognitive and language development. The results indicate that stimulating parenting was significantly associated with cognitive, language, and overall development; the home language environment was only significantly associated with language development; and parental self-efficacy was not significantly associated with any developmental outcomes. The implications of such findings reveal mechanisms for supporting healthy child development in rural China.  相似文献

Attachment security provides a well-documented protective developmental function for children exposed to individual- and community-level trauma, yet the effectiveness of prevention and intervention efforts targeting attachment during adolescence has been relatively underexplored. The Connecting and Reflecting Experience (CARE) program is a transdiagnostic, bi-generational, group-based, mentalizing-focused parenting intervention developed to dismantle the intergenerational transmission of trauma and support secure attachment relationships across the developmental spectrum within an under-resourced community. This exploratory study evaluated outcomes among caregiver-adolescent dyads (N = 32) in the CARE condition of a nonrandomized clinical trial at an outpatient mental health clinic within a diverse, urban U.S. community with disproportionate trauma exposure exacerbated by COVID-19. Caregivers predominantly identified as Black/African/African American (47%), Hispanic/Latina (38%), and/or White (19%). At pre- and post-intervention, caregivers completed questionnaires regarding parental mentalizing and their adolescents’ psychosocial functioning. Adolescents completed scales regarding attachment and psychosocial functioning. Results showed a significant decrease in caregivers’ prementalizing on the Parental Reflective Functioning Questionnaire, improvement in adolescent psychosocial functioning on the Youth Outcomes Questionnaire, and an increase in adolescents’ reports of attachment security on the Security Scale. These preliminary findings suggest that mentalizing-focused parenting interventions may be effective in fostering improved attachment security and psychosocial functioning during adolescence.  相似文献

Most research on early language learning focuses on the objects that infants see and the words they hear in their daily lives, although growing evidence suggests that motor development is also closely tied to language development. To study the real-time behaviors required for learning new words during free-flowing toy play, we measured infants’ visual attention and manual actions on to-be-learned toys. Parents and 12-to-26-month-old infants wore wireless head-mounted eye trackers, allowing them to move freely around a home-like lab environment. After the play session, infants were tested on their knowledge of object-label mappings. We found that how often parents named objects during play did not predict learning, but instead, it was infants’ attention during and around a labeling utterance that predicted whether an object-label mapping was learned. More specifically, we found that infant visual attention alone did not predict word learning. Instead, coordinated, multimodal attention–when infants’ hands and eyes were attending to the same object–predicted word learning. Our results implicate a causal pathway through which infants’ bodily actions play a critical role in early word learning.  相似文献

Developmentally appropriate sport contexts have the potential to positively influence young people’s physiological, psychological, and social outcomes. However, little is known about how families returned to sport in the wake of COVID-19-related restrictions or how socioeconomic and demographic factors influenced parents’ perceptions of barriers to returning. A nationally representative sample (N = 6183) of American youth sport parents completed a questionnaire in which they provided demographic information and answered questions related to the barriers they perceived in returning to sport, such as the risk of their child getting sick. Structural equation modeling was used to examine the relationships among a range of socioeconomic and demographic factors and these barriers to returning. Results suggest that parents from racially minoritized and urban neighborhoods held higher levels of concern over health-related and practical barriers to returning to sport. Findings highlight the importance of designing available, equitable, and appropriate youth sport contexts.  相似文献

Children’s early social interactional behaviors and symbolic play competence were studied at 14 months in a sample of 111 mother-infant pairs. The categories of social interactional behaviors, joint visual attention, socially coordinated and object oriented interactions were assessed via observations of mother-infant joint play. An index of symbolic play was derived from the child’s solitary play, which was assessed independently. We examined both the interrelations of these two types of early language predictors, and their relation to children’s language skills and maternal attention-directing strategies. Measures of children’s language comprehension and production were obtained using the MacArthur Communicative Development Inventories at 14 months, and Reynell Developmental Language Scales at 18 and 30 months. We found that at 14 months, social interactional behaviors and symbolic play competence were not statistically significantly related to each other. In line with our hypotheses, social interactional skills were associated more strongly with language production, and symbolic play competence more strongly with language comprehension. Maternal attention-directing strategies were strongly related to both children’s social interactional behaviors and symbolic play competence. Our findings indicated that maternal strategies that expanded the infant’s level of functioning were more effective in stimulating the children’s language development than were the other types of strategies.  相似文献

In a series of experiments, we assessed the efficacy of using autistic children's aberrant behaviors as reinforcers to increase their correct task responding. In Experiment 1, reinforcer conditions of stereotypy, food, and varied (food or stereotypy) were compared. In Experiment 2, the conditions were delayed echolalia, food, and varied (food or delayed echolalia), and in Experiment 3, perseverative behavior was compared with stereotypy and food as potential reinforcers. A multielement design was used for all comparisons, and side-effect measures were recorded during and after teaching sessions as well as at home. Results indicated that, in general, task performance was highest when brief opportunities to engage in aberrant behaviors were provided as reinforcers. Edibles were associated with the lowest performance. Furthermore, no negative side effects (e.g., an increase in aberrant behaviors) occurred. The results are discussed in terms of suggesting a more pragmatic treatment approach by addressing the contingent use of autistic children's aberrant behaviors as reinforcers.  相似文献

Three 7-year-old boys with histories of negative interactions were appointed to monitor individual classmates during daily noon recess. As monitors, the boys awarded points to their classmates for playing appropriately and, on rare occasions, withdrew a point for negative interactions. The three boys immediately decreased their own rates of negative interactions during the sessions in which they were appointed as monitors. Two of the boys concomitantly increased their rates of positive interactions. Their reductions in negative interactions were not maintained during reversals and did not clearly generalize to the morning or afternoon recess periods. Subsequent appointment of the boys as peer monitors during the morning recess produced similar improvements in their behavior. Results suggest that appointment to the role of peer monitor may itself function as an intervention.  相似文献

There is a need for practical methods of reinforcer assessment that systematically track ongoing changes in clients' preferences. In this study, the effects of a time-efficient reinforcer assessment package were evaluated in a multiple baseline across 3 preschoolers with autism, comparing individualized item selections by experienced teachers with children's presession preferences for items of various sensory qualities. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, as well as yielding expected improvements in accuracy. The powerful side-effects of potent reinforcers underline the importance of increased attention to reinforcer assessment in research and practice.  相似文献
