The purpose of the present study was to understand the reciprocal, bidirectional longitudinal relation between joint book reading and English receptive vocabulary. To address the research goals, a nationally representative sample of Head Start children, the Head Start Family and Child Experiences Survey (2003 cohort), was used for analysis. The children were aged 3–4 years at programme entry. The mothers' average age at programme entry was 39 years old. A parallel process model was utilized to examine the growth factors of joint book reading and receptive vocabulary in parallel. Three significant findings emerged: (1) initial levels of English receptive vocabulary and joint book reading positively covaried; (2) English receptive vocabulary and joint book reading were positively and reciprocally related to each other; and (3) slopes for joint book reading and English receptive vocabulary negatively covaried. Results suggest that joint book reading can support and scaffold Head Start children's English receptive vocabulary. Reciprocally, Head Start children's English receptive vocabulary appears to predict the extent to which they engage in joint book reading at home. Moreover, the frequency of joint book reading decreases as the children demonstrate higher levels of English receptive vocabulary. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

To examine the mechanism of visual perception of human-like body postures, we conducted a posture recognition task, a questionnaire survey, and the Interpersonal Reactivity Index (IRI). The majority of participants perceived the pseudo-posture as a human posture in the early stage (78%), but only approximately half of them reported the imagination of bodily movement (66%). These results suggest that the majority of observers perceive pseudo-postures as human postures in the early stage of perception, but this human posture perception does not necessarily lead to the visualisation of bodily movement. In a group of who received the pseudo posture as a human-posture regardless of the perception stages, the participants who imagined bodily movement (64%) showed significantly higher scores than those who did not on the Fantasy subscale of the IRI. Highly empathic participants are more likely to detect a kinematic relation between the pseudo-postures. 相似文献

Utilizing the Social Cognitive Career Theory (SCCT) as the theoretical framework, this study proposed a moderated mediation model investigating the complex functioning mechanisms of how self-efficacy beliefs and leader support can be related to research motivation among Chinese university teachers. A group of 310 Chinese teachers working in different universities completed an online survey. Results from structural equation modeling (SEM) analysis revealed distinct influencing paths from the predictor variables (i.e., self-efficacy and leader support) to the outcome variables (i.e., intrinsic and extrinsic research motivation). Specifically, self-efficacy beliefs predicted both mastery and performance goal orientations; mastery goal orientation, in turn, positively affected intrinsic and extrinsic research motivation. In contrast, leader support was non-significant for the both types of goal orientations, but exerted strong direct influences on the both types of research motivation. Bootstrapping methods in SEM showed that it was primarily the mastery goal orientation that mediated the relationships between self-efficacy beliefs and research motivation. Furthermore, the results from the SEM and simple slope analysis revealed that leader support moderated the association between self-efficacy and extrinsic research motivation. 相似文献

Drawing on Dewey's pragmatic perspective on talent cultivation and previous research on promoting employee creativity in industry, this study investigates student creativity performance in relation to teacher's encouragement, intrinsic motivation, and creative process engagement. Based on survey data collected from 140 vocational high school students who participated in a nation‐wide contest in Taiwan, path analyses were performed using structure equation modeling techniques. The results indicate that both teacher's encouragement and intrinsic motivation have a significant, although indirect, effect on student creativity, and that creative process engagement, as opposed to teacher encouragement or intrinsic motivation, has a direct and significant mediating effect on student creativity. This finding is in partial agreement with prior research which reports student creativity is positively associated with teacher encouragement and intrinsic motivation, highlighting the mediating role of creative process engagement in facilitating student creative performance. 相似文献
