The World Health Organization identified the promotion of “Nurturing Care Environments” as a global health priority. Responsive caregiving, 1 of 5 domains describing nurturing care, is critical for healthy child development. Relatively little research has evaluated population-level interventions aimed to increase responsive caregiving during the first 1,000 days of an infant's life. In this pilot study, we evaluated an intervention designed for population-level dissemination that targeted responsive caregiving. The self-guided behavioral skills training aimed to teach mothers to imitate infant vocalizations. The intervention was delivered within an on-line asynchronous training. All 3 mothers increased vocal imitative behavior following training without receiving coaching or behavior-specific feedback from an implementer. The results offer a preliminary proof of concept with implications for population-level intervention design and evaluation.  相似文献

Charcoal burning suicides in Hong Kong between 2002–2004 in the 15 to 59‐year‐old age group were investigated using the psychological autopsy method. The psychopathological profiles of charcoal burning suicides (N = 53) were compared against “other suicides” (N = 97). The two groups did not differ significantly in the prevalence of DSM‐IV axis I diagnoses with the exception of schizophrenic spectrum disorder which was less frequently associated with charcoal burning suicides. Score on “neuroticism” in the NEO‐five Factor Inventory (NEO‐FFI) was significantly higher in victims of charcoal burning suicide. There was also a trend toward higher score on “conscientiousness” in the NEO‐FFI among charcoal burners than victims of other suicide.  相似文献

Exergames are videogames that require gross motor activity, thereby combining gaming with physical activity. This study examined the role of competitive versus cooperative exergame play on short-term changes in executive function skills, following a 10-week exergame training intervention. Fifty-four low-income overweight and obese African American adolescents were randomly assigned to a competitive exergame condition, a cooperative exergame condition, or a no-play control group. Youths in the competitive exergame condition improved in executive function skills more than did those in the cooperative exergame condition and the no-play control group. Weight loss during the intervention was also significantly positively correlated with improved executive function skills. The findings link competitive exergame play to beneficial cognitive outcomes for at-risk ethnic minority adolescents.  相似文献

The current study examines 3- and 5-year-olds' representation of the concept we label 'animal' and its two nested concepts -animal(contrastive) (including only non-human animals) and animal(inclusive) (including both humans and non-human animals). Building upon evidence that naming promotes object categorization, we introduced a novel noun for two distinct objects, and analyzed children's patterns of extension. In Experiment 1, children heard a novel noun in conjunction with two non-human animals (dog, bird). Here, both 3- and 5-year-olds readily accessed animal(contrastive) and extended the noun systematically to other (previously un-named) non-human animals. In Experiment 2, children heard a novel noun in conjunction with a human and non-human animal. Here, 5-year-olds (but not 3-year-olds) accessed animal(inclusive) and extended the noun systematically to humans and non-human animals. These results underscore the developmental challenge facing young children as they identify the scope of the fundamental biological term 'animal' and its corresponding, nested concept(s).  相似文献
