An experiment with 72 three-year-olds investigated whether encoding events while seeing iconic gestures boosts children's memory representation of these events. The events, shown in videos of actors moving in an unusual manner, were presented with either iconic gestures depicting how the actors performed these actions, interactive gestures, or no gesture. In a recognition memory task, children in the iconic gesture condition remembered actors and actions better than children in the control conditions. Iconic gestures were categorized based on how much of the actors was represented by the hands (feet, legs, or body). Only iconic hand-as-body gestures boosted actor memory. Thus, seeing iconic gestures while encoding events facilitates children's memory of those aspects of events that are schematically highlighted by gesture. 相似文献

Previous research has shown that children aged 4–5 years, but not 2–3 years, show adult‐like interference from a partner when performing a joint task (Milward, Kita, & Apperly, 2014). This raises questions about the cognitive skills involved in the development of such “corepresentation (CR)” of a partner (Sebanz, Knoblich, & Prinz, 2003). Here, individual differences data from one hundred and thirteen 4‐ to 5‐year‐olds showed theory of mind (ToM) and inhibitory control (IC) as predictors of ability to avoid CR interference, suggesting that children with better ToM abilities are more likely to succeed in decoupling self and other representations in a joint task, while better IC is likely to help children avoid interference from a partner's response when selecting their own response on the task. 相似文献

Research Findings: The purpose of this study was to examine differences in the development of conflict management strategies, focusing on 3- and 5-year-olds, through a comparison of 3 neighboring Asian cultures, those of China (n = 114), Japan (n = 98), and Korea (n = 90). The dual concern model of conflict management was adopted to probe which strategy children would prefer to use in 2 hypothetical conflict situations. Results indicated that, first, for disagreement, 3-year-olds in the 3 countries equally preferred the dominating strategy. For competition for resources, 3-year-olds differed in their strategy preference across all cultures. Second, the observed strategy preference of 3- to 5-year-old children in this study was more or less different from that of older schoolchildren, regardless of culture. Practice or Policy: These findings suggest the significance of the context, the complexity of the phenomenon of the development of cultural differences, and the significance of cohort sampling. 相似文献

The literature has shown that academics often share intermediate research resources bilaterally and only infrequently deny requests for sharing. This study goes further and investigates how resource sharing is rewarded. We contrast rewarded and non-rewarded sharing, and further differentiate the types of rewards into direct (e.g., coauthorship) and reputational (e.g., acknowledgments). In a survey of 1,204 resource suppliers or recipients in the UK, Germany, and Japan, we find that rewards are commonly used, and that the form of rewarding is associated with the context in which academics work. In particular, we find that suppliers who are commercially active are more likely to agree on direct rewards. Instead, suppliers who make use of open sharing platforms are more likely to agree on reputational rewards and less likely to agree on direct rewards. For both suppliers and recipients we find that those working in larger teams are more likely to agree on direct rewards, and that their interdisciplinarity is positively linked to direct rewards and negatively to reputational rewards. These results suggest that a reward system for intermediate resources is emerging and rewarding practices are evolving with contextual differences. 相似文献

Children often find it difficult to map verbs to specific referents within complex scenes, often believing that additional features are part of the referents. This study investigated whether 3‐year‐olds could use iconic gestures to map novel verbs to specific referents. One hundred and twenty children were taught verbs that could be interpreted as change‐of‐state or manner verbs while presented with manner, end‐state, or no iconic gestures. Children were then presented with a choice that forced them to generalize either on the basis of manner or end state. Results showed that children who saw manner gestures showed a stronger manner bias compared to the other groups. Thus, the specific feature of an event encoded in gestures guides children's interpretations of novel words. 相似文献

Academic training, where senior scientists transfer their knowledge and skills to junior scientists through apprenticeship, plays a crucial role in the development of scientists. This study focuses on two aspects of academic training, autonomy and exploration, to investigate how different modes of training are incentivized and how they affect junior scientists’ performance and career prospects. Drawing on a sample of 162 supervising professors and their 791 PhD students in life science labs in Japanese universities, this study suggests two fundamental conflicts in academic training. First, autonomy granted to PhD students under apprenticeship improves their long-term performance but decreases short-term performance. Because the latter effect costs supervisors, while the former does not benefit them in general, this inter-temporal tradeoff creates an incentive conflict between supervisors and students, inducing non-autonomous training. The short-term cost for supervisors can be compensated in the form of labor input or reputation gain from previous students in the long term, but this typically happens when students are trained with limited scope of exploration, which hinders the originality of students’ knowledge production. This reduces the diversity of knowledge production, presenting another incentive conflict between individual scientists and the collective scientific community. 相似文献

This study investigated whether seeing iconic gestures depicting verb referents promotes two types of generalization. We taught 3- to 4-year-olds novel locomotion verbs. Children who saw iconic manner gestures during training generalized more verbs to novel events (first-order generalization) than children who saw interactive gestures (Experiment 1, N = 48; Experiment 2, N = 48) and path-tracing gestures (Experiment 3, N = 48). Furthermore, immediately (Experiments 1 and 3) and after 1 week (Experiment 2), the iconic manner gesture group outperformed the control groups in subsequent generalization trials with different novel verbs (second-order generalization), although all groups saw interactive gestures. Thus, seeing iconic gestures that depict verb referents helps children (a) generalize individual verb meanings to novel events and (b) learn more verbs from the same subcategory. 相似文献
