Visual speech cues from a speaker's talking face aid speech segmentation in adults, but despite the importance of speech segmentation in language acquisition, little is known about the possible influence of visual speech on infants' speech segmentation. Here, to investigate whether there is facilitation of speech segmentation by visual information, two groups of English-learning 7-month-old infants were presented with continuous speech passages, one group with auditory-only (AO) speech and the other with auditory-visual (AV) speech. Additionally, the possible relation between infants' relative attention to the speaker's mouth versus eye regions and their segmentation performance was examined. Both the AO and the AV groups of infants successfully segmented words from the continuous speech stream, but segmentation performance persisted for longer for infants in the AV group. Interestingly, while AV group infants showed no significant relation between the relative amount of time spent fixating the speaker's mouth versus eyes and word segmentation, their attention to the mouth was greater than that of AO group infants, especially early in test trials. The results are discussed in relation to the possible pathways through which visual speech cues aid speech perception. 相似文献

Parental substance misuse is a significant child welfare issue and associated with increased risk of child maltreatment. The aim of the present study was to understand what social care outcomes children who live with parental substance misuse have, and to assess factors associated with those social care outcomes over a two-year period. The paper reports on a retrospective longitudinal study of 299 children all living with parental substance misuse and referred to one local authority in England. Data were collected from children's social work case files about procedural social care outcomes and factors which may be associated with those outcomes. Using cluster analysis, a new typology of children's longitudinal trajectories through the children's social care system was developed, consisting of five distinct types. Analysis indicated that some children received too little intervention from children's social care despite ongoing concerns, while other children were potentially unnecessarily caught up in the social care system. Factors associated with children having the poorest outcomes were: caregiver instability resulting from substance misuse, parenting capacity and household instability. The study's findings indicate that some children who live with parental substance misuse are at significant risk of harm, but others are not and may be better supported through non-statutory services such as early help. 相似文献

How prevalent are Republican and Democratic student groups, and why are some schools home to Republican and Democratic student groups while other schools are not? Some commentators and scholars suggest that Republican student groups may be less prevalent than Democratic student groups and, when present, will likely be found at “red schools” (rather than “blue schools”) in Republican-leaning areas of the country. However, other scholars argue that both Republican and Democratic student groups should be similar in their overall prevalence and located at a similar set of “engaged schools” (as opposed to “unengaged schools”). Analyzing our original database of Republican and Democratic student organizations across 1,953 four-year, not-for-profit U.S. colleges and universities, we first show that Republican student groups are nearly as common as Democratic student groups: Republican student groups can be found at 39% of campuses, while Democratic student groups are present on 40% of campuses. Employing binary and multinomial logistic regression analyses, we then show that Republican and Democratic student groups tend to be located at the same types of schools, that is, larger, wealthier, public schools that offer political science majors. Our article holds significant implications for theorizing on student organization presence more generally. 相似文献

Internalizing and externalizing problems are likely to co-occur in childhood and are related to concurrent and prospective mental health outcomes. We examined the longitudinal relations among internalizing and externalizing problems during middle childhood utilizing the Random Intercept – Cross Lagged Panel Model. We investigated three research questions: (1) how overall levels of internalizing and externalizing problems are related, (2) whether internalizing and externalizing problems predict each other longitudinally, and (3) whether girls and boys show different longitudinal associations among internalizing and externalizing problems. Mother-reported internalizing and externalizing problems were used through first to sixth grade (N = 1364). Results showed positive random intercepts and positive within-time correlations of internalizing and externalizing problems. Further, internalizing problems predicted externalizing problems at the within-person level. Although previous research mostly has shown a significant effect from externalizing problems to internalizing problems, the current study shows that when within- and between-person variance are disentangled, internalizing problems also may predict externalizing problems. 相似文献

本文运用扎根理论,从质上对大学生的网络使用好恶情况进行了分析。根据所搜集的数据,我们发现大学生对网络的使用情况与网络使用的积极特征——使用效率高、沟通便捷、信息收集与娱乐功能丰富等相关。当然,网络的负面影响如对身体的危害、安全隐患、可疑信息及费用等问题也不容忽视。基于此,对大学生进行媒体教育是非常必要的,可以通过开展具体的教育和培训,教给他们有效的网络使用学习模式,以帮助他们解决网络使用中的负面问题。 相似文献
