Tomasello, Carpenter, and Liszkowski (2007) present a comprehensive review of the infant pointing literature. They conclude that infant pointing demonstrates communicative intent from its onset, at about 1 year of age. In this commentary, it is noted that for infants to understand communicative intent, they must have a concept of self and others as intentional agents. Evidence is reviewed to argue that this is not possible until 18-24 months of age. A leaner explanation of how infants might initially succeed in pointing tasks without understanding communicative intent is considered.  相似文献

OBJECTIVE: The objective is to describe the prevalence of child sexual abuse (CSA) among women in New Zealand, document ethnic specific rates, and outline the frequency of abuse experienced and the most commonly identified perpetrators. Associations between CSA and later adverse consequences were also explored. METHODS: Retrospective report from a random sample of 2,855 women aged 18-64 years old in two regions in New Zealand. Face-to-face interviews with one randomly selected woman from each household were conducted. RESULTS: The overall prevalence rates for CSA were 23.5% for women from the urban region and 28.2% from the rural region. In both urban and rural regions, Māori women more frequently reported experiences of CSA than women from European and other ethnic groups (urban: 30.5% vs. 17.0% and rural: 35.1% vs. 20.7%). The median age of onset of the abuse was 9 years, and the median estimated age of the abuser was 30 years. Half of those who experienced CSA reported that it occurred once or twice, 27% "a few times," and 23% "multiple times." Sole perpetrators were involved in 83% of cases. The majority of cases were perpetrated by a family member, most frequently male. Compared with non-victims, victims of CSA were twice as likely to experience later intimate partner violence and violence by others. CONCLUSIONS: This study reports on a large, population-based sample in an ethnically diverse population in New Zealand, providing the first ethnic-specific rates of CSA available. Findings suggest important priorities for prevention and intervention activities.  相似文献

Relations between mothers' mind-mindedness (appropriate and nonattuned mind-related comments) at 8 months (= 206), and children's educational attainment at ages 7 (= 158) and 11 (= 156) were investigated in a British sample. Appropriate mind-related comments were positively correlated with reading and mathematics performance at both ages but only in the low-socioeconomic status (SES) group. Path analyses showed that in the low-SES group, appropriate mind-related comments directly predicted age-11 reading performance, with age-4 verbal ability mediating the relation between appropriate mind-related comments and age-7 reading. In contrast, maternal sensitivity and infant–mother attachment security did not predict children's educational attainment. These findings are discussed in terms of genetic and environmental contributions to reading and mathematics performance.  相似文献

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole-school health promotion. Such groups can coordinate multi-component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole-school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole-school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.  相似文献

An increasing number of scholars are being trained in the field of mind, brain, and education (MBE), yet discussions of trainees' needs and how to meet them are rare. We, the inaugural International Mind, Brain, and Education Society (IMBES) Trainee Board, identify three broad needs of MBE trainees: guidance and support, greater access to and connections among the MBE community, and professional development. We report a first step to address these needs: a daylong trainee conference, which included sessions to foster connections among trainees, provide mentorship from MBE leaders, and provide knowledge and skill building for careers. Attendees' survey results suggest the conference successfully supported trainees' development. As substantial trainee needs remain, we offer specific ways that principal investigators, institutions, funding agencies, future IMBES trainee boards, and the MBE community can further address trainees' needs to support early‐career development and strengthen the MBE field generally.  相似文献

Currently, only epidemiological injury data have been reported for the new extreme sport of aggressive inline skating, or trick skating. No studies have examined the biomechanics of this sport, which involves repetitive jumping and landing from railings, ramps, and ledges, often over 1 m in height. We present results of a pilot study that examined the effect of skater experience and lower extremity biomechanics on energy absorption ability, and observed balance strategies used during two basic tricks. In these tricks, the skater jumps onto an elevated rail and maintains balance while standing in a single position (stall) or sliding along the rail (grind). Lower extremity joint kinematics, impact force characteristics, and general movement behaviours were examined during landing and balance phases. Ten male skaters performed ten stalls and ten frontside grinds on an instrumented grind rail, capable of measuring vertical force. Vertical impact force was found to decrease with increasing skater experience in stalls (r = -0.84, P = 0.002) and grinds (r = -0.84, P = 0.009). This might imply that less-experienced skaters are (subconsciously) more concerned about maintaining balance than refining technique to minimize impact force. Similar to drop landing experiments, peak impact force decreased with increasing knee flexion during stalls (r = -0.65, P = 0.04). During stalls, skaters demonstrated classic balance maintenance strategies (ankle, hip, or multi-joint) depending on trick length. During grinds, skater centre of mass never passed over the rail base of support, suggesting the use of momentum produced from obliquely approaching the rail.  相似文献

The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented.  相似文献
