汉字独体字识别中的框架结构效应 总被引:3,自引:1,他引:2
本研究用两个实验证明了汉字独体字识别中存在框架结构效应。所谓框架结构就是构成一个字基本框架的笔画。实验一发现框架结构具有明显的启动效应。实验二发现独体字的识别从笔画开始,提取框架结构是独体字识别过程中的必经阶段,两个实验均未发现字频效应。 相似文献

E-learning systems are capable of providing more adaptive and efficient learning experiences for learners than traditional classroom settings. A key component of such systems is the learning policy. The learning policy is an algorithm that designs the learning paths or rather it selects learning materials for learners based on information such as the learners’ current progresses and skills, learning material contents. In this article, the authors address the problem of finding the optimal learning policy. To this end, a model for learners’ hierarchical skills in the E-learning system is first developed. Based on the hierarchical skill model and the classical cognitive diagnosis model, a framework to model various mastery levels related to hierarchical skills is further developed. The optimal learning path in consideration of the hierarchical structure of skills is found by applying a model-free reinforcement learning method, which does not require any assumption about learners’ learning transition processes. The effectiveness of the proposed framework is demonstrated via simulation studies. 相似文献

名字在个体印象评价和人际交往中发挥着重要作用。本研究结合刻板印象内容模型, 从刻板印象维护视角出发, 通过3个研究考察了性别化名字的热情能力感知, 基于此探究性别化名字对不同性别个体的印象评价及人际交往的影响。结果发现:(1)人们对男性化名字的能力评价高于女性化名字, 对女性化名字的热情评价高于男性化名字; (2)性别化名字影响男性的能力评价和女性的热情评价; (3)性别化名字影响人们对女性的交友偏好, 热情评价在其中起到完全中介作用; 性别化名字影响人们和男性的共事偏好, 能力评价起到完全中介作用。研究揭示了性别化名字影响印象评价的模式, 并为理解人际交往中名字的作用机制提供了新的研究思路。 相似文献

Family socioeconomic status (SES) has been frequently linked to children’s early development. Treating SES as an aggregated variable has many issues, as different components of SES may relate to child outcomes through divergent mechanisms. The purpose of the study was to examine whether parents’ engagement in home learning activities and children’s participation in extracurricular activities (EAs) would function as pathways through which individual SES components related to children’s school readiness. A total of 588 families with preschool‐aged children were recruited from Guangdong province in China. Children’s receptive vocabulary, Chinese reading, and early math skills were individually assessed at three time points, and children’s social skills were rated by parents. Parents reported their engagement in home learning activities with children and their children’s participation in EAs. The results showed that all three components of family SES were related to multiple aspects of children’s school readiness, but through different pathways. Parental income was related to children’s school readiness through EA participation only; parental education and occupational status were associated with school readiness via both parental engagement and child EA participation. The findings suggest that considering SES components separately will produce a more nuanced understanding of the divergent pathways through which family SES may relate to children’s school readiness. Chinese government may provide parent education programs focused on cognitive stimulation for low‐SES families to promote children’s school readiness. Furthermore, the government needs to ensure children’s equal access to EAs to prevent increasing the developmental gap among children from discrepant socioeconomic backgrounds. 相似文献

Bullying at workplaces is a growing problem associated with several antecedents and outcomes of psychological disorders. Extant literature shows the relationship of victimization with the owning‐up curriculum to confront bullying, but so far there is little research to cure the issue of bullying through ethics and there is no study to check the impact of ethical lessons and exercises in training materials to curb bullying at workplace. The current paper is based on a literature review of aggression and bullying, and chiefly addresses the HR practices in rescuing the people from peer victimization. Conceptually segregating supervisor‐subordinate (vertical) and peer‐peer (horizontal) bullying psychology, this paper attempts to see what possible corrective steps can be taken by senior managers, supervisors and psychologists to resolve this critical problem through interior capacities. In this paper, we have developed three propositions for conducting a future empirical investigation in connection to a cohort study. By addressing the counterproductive/deviant behavior, the present report is likely to be beneficial for psychology scientists and HR practitioners in noticing and resolving the bullying issues at the workplace for the well‐being of employees. 相似文献

我国自古便有“通过强调时间流逝而珍惜当下”的教育与文化传统,对这一“时间认知影响时间行为”的作用机理,当前所知不多。采用问卷法对2232名低年级大学生调查,以考察同一性状态、生命时间流逝情绪、流逝注意与时间管理之间的关系.结果显示:(1)同一性获得、延缓状态正向直接预测时间管理倾向各维度(时间价值感、监控观与效能感);早闭状态直接正向预测时间监控观、负向预测效能感;扩散状态直接负向预测时间价值感和监控观;(2)获得状态通过流逝情绪间接预测监控观和效能感;(3)延缓状态通过流逝情绪、流逝注意间接预测监控观、效能感,还能通过流逝注意间接预测价值感;(4)早闭状态通过流逝注意间接预测时间管理各维度,其中,流逝注意在“早闭—价值”间起完全中介作用。 相似文献

The visual system is remarkably efficient at extracting summary statistics from the environment. Yet at any given time, the environment consists of many groups of objects distributed over space. Thus, the challenge for the visual system is to summarize over multiple groups. The current study investigates the capacity and computational efficiency of ensemble perception, in the context of perceiving mean sizes of multiple spatially intermixed groups of circles. In a series of experiments, participants viewed an array of one to eight sets of circles. Each set contained four circles in the same colors, but with different sizes. Participants estimated the mean size of a probed set. The set that would be probed was either known before onset of the array (pre-cue condition) or afterwards (post-cue condition). By comparing estimation error in the pre-cue and post-cue conditions, we found that participants could reliably estimate mean sizes for approximately two sets (Experiment 1). Importantly, this capacity was robust against attention bias toward individual objects in the sets (Experiment 2). Varying the exposure time to stimulus arrays did not increase the capacity limit, suggesting that ensemble perception could be limited by an internal resource constraint, rather than the speed of information encoding (Experiment 3). Moreover, we found that the visual system could not encode and hold more individual items than ensemble representations (Experiment 4). Taken together, these results suggest that ensemble perception provides an efficient way of information processing but with constraints. 相似文献

Reference directions and reference objects in spatial memory of a briefly viewed layout 总被引:1,自引:0,他引:1
Two experiments investigated participants' spatial memory of a briefly viewed layout. Participants saw an array of five objects on a table and, after a short delay, indicated whether the target object indicated by the experimenter had been moved. Experiment 1 showed that change detection was more accurate when non-target objects were stationary than when non-target objects were moved. This context effect was observed when participants were tested both at the original learning perspective and at a novel perspective. In Experiment 2, the arrays of five objects were presented on a rectangular table and two of the non-target objects were aligned with the longer axis of the table. Change detection was more accurate when the target object was presented with the two objects that were aligned with the longer axis of the table during learning than when the target object was presented with the two objects that were not aligned with the longer axis of the table during learning. These results indicated that the spatial memory of a briefly viewed layout has interobject spatial relations represented and utilizes an allocentric reference direction. 相似文献

试论网络视域中的宗教传播——以佛教网站为例 总被引:2,自引:1,他引:1
本文以佛教网站为例讨论网络视域中的宗教传播.认为佛教网站就是有独立域名、独立服务器、独立IP地址或虚拟主机的以传播、交流、弘扬佛教教义、佛教文化、佛教精神为主旨的网站;而且,现有的佛教网站,虽然主体上多属宗教的网络化,但其局部也正在具有在线宗教的某些特质.以此,作为网络传播之主体的网站主办者便应以最大化宗教的积极功能为第一要务. 相似文献
