Although one might expect parents’ mind-mindedness (MM; the propensity to view children as mental agents) to relate to everyday mental-state talk (MST) and theory-of-mind capacity, evidence to support this view is lacking. In addition, both the uniqueness and the specificity of relations between parental MM, parental MST, and children's false belief understanding (FBU) are open to question. To address these three gaps, this study tracked 117 preschoolers (60 boys) and their parents across a 13-month period (Mage = 3.94 years, SD = 0.53, at Time 1). Parental MM, MST, and theory-of-mind capacity showed little overlap. Both MM and MST were weakly associated with children's concurrent FBU, but in line with social constructivist accounts, only MST predicted later FBU. 相似文献

This study examines how three elementary teachers refer to pictorial models (photographs, drawings, and cartoons) during science read-alouds. While one teacher used realistic photographs for the purpose of visually verifying facts about crystals, another employed analytical diagrams as heuristic tools to help students visualize complex target systems (rainbow formation and human eye functioning). Another teacher used fictional cartoons to engage students in analogical storytelling, communicating animal camouflage as analogous to human “blending in.” However, teachers did not always explicitly convey the representational nature of pictorial models (analog and target as separate entities). It is argued that teachers need to become more aware of how they refer to pictorial models in children’s science books and how to promote student visual literacy. 相似文献

This study examined trunk muscle activation, balance and proprioception while squatting with a water-filled training tube (WT) and a traditional barbell (BB), with either closed (CE) or open eyes (OE). Eighteen male elite Gaelic footballers performed an isometric squat under the following conditions: BB-OE, BB-CE, WT-OE and WT-CE. The activity of rectus abdominis (RA), external oblique (EO) and multifidus (MF) was measured using electromyography, along with sway of the centre of pressure (CoP) using a force platform. Only the EO and the MF muscles exhibited an increased activity with WT (p < 0.01). In the medio-lateral direction both the velocity and range of the CoP increased significantly with WT (p < 0.01). Interestingly, the range of the CoP for the WT-CE condition was significantly lower than WT-OE (p < 0.05, d = 0.44), whilst the velocity of the CoP was marginally reduced (d = 0.29). WT elicited a greater level core muscle activation and created a greater challenge to postural stability when compared to a BB. It appears that WT does not benefit from vision but emphasises the somatosensory control of balance. The use of WT may be beneficial in those sports requiring development of somatosensory/proprioceptive contribution to balance control. 相似文献

As a result of the ever-growing list of course technologies and software programs, higher education faculty and administration often debate which new tools are most valuable to students. This article investigates whether the use of an online textbook supplemental program (MindTap®) has a positive influence on student performance. The impact of goal achievement orientations is also discussed and factored into the analysis, as it provides insight into the motivations that drive the usage of online supplemental course materials. Results found that usage of MindTap® is positively predicted by a mastery approach goal orientation. More importantly, it was shown that usage of MindTap® positively predicts student performance, above and beyond the impact of age, gender, SAT score and goal achievement orientation. 相似文献

The aim of the present study was to compare cardiac structure as well as global and regional cardiac function in athletes with and without myocardial fibrosis (MF). Cardiac magnetic resonance imaging with late gadolinium enhancement was used to detect MF and global cardiac structure in nine lifelong veteran endurance athletes (58?±?5 years, 43?±?5 years of training). Transthoracic echocardiography using tissue-Doppler and myocardial strain imaging assessed global and regional (18 segments) longitudinal left ventricular function. MF was present in four athletes (range 1–8?g) and not present in five athletes. MF was located near the insertion points of the right ventricular free wall on the left ventricle in three athletes and in the epicardial lateral wall in one athlete. Athletes with MF demonstrated a larger end diastolic volume (205?±?24 vs 173?±?18?ml) and posterior wall thickness (11?±?1 vs 9?±?1?mm) compared to those without MF. The presence of MF did not mediate global tissue velocities or global longitudinal strain and strain rate; however, regional analysis of longitudinal strain demonstrated reduced function in some fibrotic regions. Furthermore, base to apex gradient was affected in three out of four athletes with MF. Lifelong veteran endurance athletes with MF demonstrate larger cardiac dimensions and normal global cardiac function. Fibrotic areas may demonstrate some co-localised regional cardiac dysfunction, evidenced by an affected cardiac strain and base to apex gradient. These data emphasize the heterogeneous phenotype of MF in athletes. 相似文献

Both Attention-Deficit/Hyperactivity Disorder (AD/HD) and divorce are very prevalent in western societies, and they may occur together. AD/HD is generally viewed as a neurobiological disorder, which has led to a commonly held belief that social-environmental factors play little role in the symptom profile of children diagnosed with the disorder. This study investigated the association between parental divorce, remarriage, multiple transitions, the quality of relationships with family members and the psychological well-being of children and adolescents with AD/HD. First, differences in children’s AD/HD symptom profiles in relation to parents’ divorce status (single/multiple divorce) and family composition (single parent/stepfamily) were examined. Second, the association between the quality of children’s relationships with each family member and parents’ marital status (divorced/non-divorced) and family composition was investigated. In addition, age, gender and AD/HD subtype differences were assessed. Third, the association between the quality of children’s interactions with family members and children’s AD/HD symptom profile was explored. No significant differences in children’s behavioural profiles were found in terms of parents’ divorce status. Living in stepfamilies was associated with greater AD/HD severity and social malfunctioning. Disruptive parent–child and sibling relationships were found to be related to children’s age, gender, AD/HD subtype and parents’ marital status. Further, poor interactions with family members correlated with children’s AD/HD severity and psychological well-being. In summary, divorce, remarriage and the quality of relationships with family members are important correlates of the symptom profile of children with AD/HD, and this emphasises the need for special treatment modules for these families. 相似文献

This paper explores the benefits of using in-house periodicals for writing the history of interest groups and unions in southern Africa. In particular, it focuses on using The Farmer magazine as a source to write more nuanced social and cultural histories of white farmers in Zimbabwe. The importance of The Farmer to the white farming community is laid out and it is argued that long-term and detailed readings of this magazine offer the opportunity to explore the evolutions in discourse within the farming community, the processes of transition and the ambiguities of independence for a group like the white farmers. The uses described are ones that have rarely been put into practice in southern Africa, but are also ones that can be easily transposed to other settings and context. 相似文献

This meta‐analysis seeks to integrate findings from 25 years of research on family correlates of young children's false belief understanding (FBU). Using data from 93 studies of 3‐ to 7‐year‐old children, we examined the correlations between FBU and four of the most widely studied family factors: parental socioeconomic status, number of siblings, parental mental‐state talk, and mind‐mindedness. FBU exhibited modest associations with each family variable and these associations held even when individual differences in verbal ability were taken into account. Moderator analyses revealed key child‐related factors (e.g., age, gender) as well as methodological factors that amplified or attenuated the relations between FBU and each family variable. Crucially, available longitudinal data highlight the importance of family factors in the development of FBU. 相似文献
