In the early stages of word learning, children demonstrate considerable flexibility in the type of symbols they will accept as object labels. However, around the 2nd year, as children continue to gain language experience, they become focused on more conventional symbols (e.g., words) as opposed to less conventional symbols (e.g., gestures). During this period of symbolic narrowing, the degree to which children are able to learn other types of labels, such as arbitrary gestures, remains a topic of debate. Thus, the purpose of the current set of experiments was to determine whether a multimodal label (word + gesture) could facilitate 26-month-olds' ability to learn an arbitrary gestural label. We hypothesized that the multimodal label would exploit children's focus on words thereby increasing their willingness to interpret the gestural label. To test this hypothesis, we conducted two experiments. In Experiment 1, 26-month-olds were trained with a multimodal label (word + gesture) and tested on their ability to map and generalize both the arbitrary gesture and the multimodal label to familiar and novel objects. In Experiment 2, 26-month-olds were trained and tested with only the gestural label. The findings revealed that 26-month-olds are able to map and generalize an arbitrary gesture when it is presented multimodally with a word, but not when it is presented in isolation. Furthermore, children's ability to learn the gestural labels was positively related to their reported productive vocabulary, providing additional evidence that children's focus on words actually helped, not hindered, their gesture learning. 相似文献

社会认知的两个基本维度热情与能力之间存在一种特殊的关系, 它既可能是晕轮效应所认为的正向关系, 也可能是补偿效应和影射效应所认为的负向关系, 还有可能是受多种因素影响的正交关系。热情与能力的关系受到知觉者自身因素、知觉对象的特点、知觉者与知觉对象的关系以及外部环境等多种因素的影响, 而热情与能力关系的内部机制不明确是学者们对其关系产生分歧的根本原因。今后需要进一步探讨热情与能力的内部机制, 进行跨文化的检验和比较研究, 进一步探索其关系的影响因素, 建构热情与能力的关系模型。 相似文献

退休是个体在特定年龄领取养老金的行为及动态过程。退休模型包括退休的影响因素模型、退休过程模型和退休结果模型三类。其中,退休的影响因素模型包括前因变量模型和退休多水平模型,分别从个人-环境和宏观角度提出了影响退休的各类因素;退休过程模型包括退休决策三阶段模型、退休时间过程模型和退休适应动态模型,分别从阶段性、个体差异性和动态性的角度揭示了退休过程的心理特点;退休结果模型分析了退休对个人和组织的影响。退休四阶段模型是在西方模型的基础上结合中国国情提出的一个整合模型。未来研究应丰富研究对象的类型、揭示影响退休的心理学变量的作用机制、加强应用性并进行本土化研究。 相似文献

When deceiving, one should remember to whom a falsified story was previously told; otherwise he or she may include inconsistencies, and the deception will probably be discovered. Bearing this in mind, we investigated the potential relationship between deception and the ability to remember to whom a piece of information was previously told (i.e., destination memory). Forty-one adults were given a destination memory task in which they had to decide to whom proverbs had previously been told. They were also given a questionnaire about deception (e.g., “I sometimes tell lies if I have to) and a cognitive theory of mind task in which they had to predict the behaviour of protagonists who hold a mistaken belief about the state of the world. Results showed a positive correlation between deception and destination memory (p <?.001), a relationship that was further mediated by cognitive theory of mind ability (p?<?.01). Deception requires monitoring and inferring what targets know, suspect, and believe. This monitoring ability (i.e., cognitive theory of mind) results in better processing of the target and consequently better destination memory. By showing the involvement of deception and theory of mind in destination memory, our findings emphasize the memory variations in social and interpersonal interactions. 相似文献

The attraction effect shows that adding a third alternative to a choice set can alter preference between the original two options. For over 30 years, this simple demonstration of context dependence has been taken as strong evidence against a class of parsimonious value‐maximising models that evaluate alternatives independently from one another. Significantly, however, in previous demonstrations of the attraction effect alternatives are approximately equally valuable, so there was little consequence to the decision maker irrespective of which alternative was selected. Here we vary the difference in expected value between alternatives and provide the first demonstration that, although extinguished with large differences, this theoretically important effect persists when choice between alternatives has a consequence. We use this result to clarify the implications of the attraction effect, arguing that although it robustly violates the assumptions of value‐maximising models, it does not eliminate the possibility that human decision making is optimal. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd. 相似文献

Rare-earth (RE) elements are helpful in improving the mechanical properties of cemented carbides. In this work, the formation of Y2O3 in functionally graded cemented carbides is investigated using transmission electron microscopy. The results indicate that Y2O3 can stabilize the Co phase with the face-centred cubic structure (α-Co), since it has a cubic structure similar to the high-temperature Co phase. The α-Co phase has a higher plasticity than ε-Co, and this suggests a possible mechanism for the role of RE elements in toughening cemented carbides. 相似文献

The purpose of the present study was to explore English as a Foreign Language (EFL) teacher’s motivations for teaching and testing a model of burnout based on motivations and emotions using structural equation modeling (SEM). For this purpose, a total number of 326 Iranian EFL teachers in different language institutes completed the related scales. Results of the study showed that altruistic and intrinsic factors are the main motivations of EFL teachers. Results of SEM indicated that both motivations and emotions predicted different dimensions of burnout. However, emotions had a stronger effect on burnout dimensions than motivational factors. Finally, the pedagogical implications were discussed based on the results of the study. 相似文献
