According to one theory, synaesthesia develops, or is preserved, because it helps children learn. If so, it should be more common among adults who faced greater childhood learning challenges. In the largest survey of synaesthesia to date, the incidence of synaesthesia was compared among native speakers of languages with transparent (easier) and opaque (more difficult) orthographies. Contrary to our prediction, native speakers of Czech (transparent) were more likely to be synaesthetes than native speakers of English (opaque). However, exploratory analyses suggested that this was because more Czechs learned non-native second languages, which was strongly associated with synaesthesia, consistent with the learning hypothesis. Furthermore, the incidence of synaesthesia among speakers of opaque languages was double that among speakers of transparent languages other than Czech, also consistent with the learning hypothesis. These findings contribute to an emerging understanding of synaesthetic development as a complex and lengthy process with multiple causal influences.  相似文献

发展性阅读障碍(下文简称为"阅读障碍")不仅会影响个人的终身发展,还会对社会造成沉重的经济负担,深入探讨相关的神经机制,对实现阅读障碍的早期预测和干预十分重要。以往关于阅读障碍神经机制的模型多集中于大脑,近些年的研究发现,阅读障碍也与小脑异常有关,但到目前为止我们仍不清楚两者的关系。通过总结最新的研究进展,我们发现小脑在阅读障碍中可能发挥着多种功能,且小脑异常与阅读障碍可能互为因果。在此基础之上,我们提出了"阅读中小脑与大脑的功能映射假说",旨在从一个全新的角度揭示小脑与阅读的关系,以及两者与大脑的关系。相关内容对全面揭示阅读障碍的神经机制,以及小脑在高级认知加工中的作用,具有重要的启示意义。  相似文献

假设检验思维过程中的启发式策略研究   总被引:13,自引:2,他引:13  
本研究运用自编的一个关于规则发现的计算机程序研究了大学生问题解决过程中形成假设、设计实验、实施检验三个阶段上的“假设———检验”的思维过程。结果发现,规则差别对规则发现有显著影响,反馈方式在本实验条件下没有主效应,启发式是假设检验过程中的重要思维策略  相似文献

In analytic hierarchy process (AHP), a ratio scale (π1, π2, ⋯, πt) for the priorities of the alternatives {T1, T2, ⋯, Tt} is used for a decision problem in which πi/πj is used to quantify the ratio of the priority of Ti to that of Tj. In a group decision‐making setup, the subjective estimates of πi/πj are obtained as entries of a pairwise comparison matrix for each member of the group. On the basis of these pairwise comparison matrices, one of the topics of interest in some situation is the total rank ordering of the priorities of the alternatives. In this article, a statistical method is proposed for testing a specific total rank ordering of the priorities of the alternatives. The method developed is then illustrated using numerical examples.

Hand mouthing often has been described as a stereotypic response that is maintained by non-social (automatic) reinforcement; however, data supporting this conclusion can be found in relatively few studies. This series of studies presents an experimental analysis of conditions associated with the maintenance of hand mouthing. In Experiment 1, a functional analysis was conducted for 12 individuals who engaged in chronic hand mouthing to determine whether the behavior is usually maintained independent of social contingencies. Results obtained for 10 subjects were consistent with an automatic reinforcement hypothesis; the remaining 2 subjects' hand mouthing was maintained by social-positive reinforcement. Based on these results, Experiment 2 was designed to identify the specific reinforcing properties of hand mouthing. Each of 4 subjects was provided with a toy that substituted for hand mouthing, and preference for a specific topography of toy manipulation (hand-toy contact or mouth-toy contact) was measured. Results indicated that hand stimulation was the predominant reinforcer for all subjects. Experiment 3 provided an extension of Experiment 2 in that the same responses were measured across a variety of toys presented to each of 5 subjects. Results again indicated that hand stimulation was the predominant reinforcer for all subjects. Implications of these results are discussed with relevance to treatment.  相似文献

论法官的角色伦理   总被引:2,自引:0,他引:2  
法官的角色伦理研究是一个有别于法官职业道德研究的理论视角。法官是一个角色丛 ,包括了官员和司法者二重基本角色 ,所以 ,法官的角色伦理不只是对其作为一个职业者的规范 ,而是二重角色规范的综合体 ,它反映了社会对法官的综合道德评价。作为“官”的角色 ,它被赋予的特殊道德要求是公仆意识、廉洁和公正 ;作为司法者 ,其特殊的职业伦理是刚毅、谨慎和勤勉。法官角色伦理建设是以理性人与经验人的统一为人性假设前提的 ,其基本思路是立足于制度道德建设 ,加强思想道德教育 ,适度进行奖惩。总之 ,一个有别于法官职业道德的理论视角 ,对于法官的道德建设具有重大的理论意义和实践价值。  相似文献

The purpose of this study was to examine the effects of focus of attention cues on movement coordination and coordination variability in the lower extremity. Twenty participants performed the standing long jump under both internal and external focus of attention conditions. A modified vector coding technique was used to evaluate the influence of attentional focus cues on lower extremity coordination patterns and coordination variability during the jumps. Participants jumped significantly further under an external focus of attention condition compared with an internal focus of attention condition (p = .035, effect size = .29). Focus of attention also influenced coordination between the ankle and knee, F(6, 19) = 2.87, p = .012, effect size = .388, with participants primarily using their knees under the internal focus of attention, and using both their ankles and knees under the external focus of attention. Attentional focus cues did not influence ankle-knee, F(1, 19) = 0.02, p = .98, effect size = .02, or hip-knee, F(1, 19) = 5.00, p = .49, effect size = .16, coordination variability. Results suggest that while attentional focus may not directly influence movement coordination condition, there is still a change in movement strategy resulting in greater jump distances following an external focus of attention.  相似文献

Business and public organisations hire fraud examiners to conduct private investigations when there is suspicion of misconduct or financial crime. Fraud examiners carry out their investigation based on a mandate. Often, individuals in the organisation are suspects. The blame game hypothesis is concerned with factors that cause blame attribution to some individuals but not to others. In this case study, only executives were blamed who had not disclosed corruption information to a major shareholder and to the chief executive officer.  相似文献

Theories of autobiographical memory distinguish between involuntary and voluntary memories. While involuntary memories are retrieved with no conscious intention and are therefore unexpected, voluntary memories are both intended and expected. Recent research has shown that participants sometimes classify their memories as either involuntary or voluntary based on retrieval effort instead of intention. These findings question whether intention really is the defining difference between these two types of retrieval or whether retrieval effort is also an important determinant. In two experimental studies, we investigated the extent to which participants rely on retrieval effort while classifying their memories as involuntary or voluntary. We created experimental conditions that maximize the probability of one type of retrieval while minimizing the probability of another type. Participants reported autobiographical memories in each condition while the programme registered their retrieval time. They then classified their memories as either voluntary or involuntary and rated all memories on perceived retrieval effort. This gave us four categories of memories: experimentally defined voluntary and involuntary memories with an objective measure of effort (retrieval time) and subjectively classified involuntary and voluntary memories with a subjective measure of effort. This allowed us to investigate the relative contribution of intention and effort to involuntary and voluntary memories. We replicated and extended previous findings by showing that the majority of memories were classified as involuntary independently of whether they were retrieved in the experimentally defined voluntary or involuntary condition. This could indicate that subjective effort is more important than intention for the involuntary–voluntary distinction in contrast with existing theories. We discuss theoretical and methodological implications of this finding.  相似文献
