In Hungary, there has been limited public debate about genetically modified crops, unlike in some Western countries. The mass media has published little to inform Hungarian lay people about genetically modified (GM) crops or their relevance to the country. Nevertheless, the media did convey some general impressions, mainly from within an Anti-GM Threat framing of the issue. This mass media frame was evident in lay focus group discussions—e.g. GM crops branded a food risk, general focus on risks, health risk identified as important risk, foreign companies regarded as source of the problem and as being ‘just out for profit’, image of corn, rhetoric of deterioration, etc. This overlap supports theories which suggest that media framings provide a resource which can be appropriated for public understanding. At the same time, however, dominant media framings were also mentioned only vaguely or in a somewhat modified way. Other issues raised in the media framing, not resonating with wider cultural themes, were absent from focus group discussions (e.g. environmental concerns). And participants were also able to rely on other conversational resources (analogous reasoning and cultural themes) to formulate some additional issues beyond the media reportage.  相似文献

Accessing action knowledge is believed to rely on the activation of action representations through the retrieval of functional, manipulative, and spatial information associated with objects. However, it remains unclear whether action representations can be activated in this way when the object information is irrelevant to the current judgment. The present study investigated this question by independently manipulating the correctness of three types of action‐related information: the functional relation between the two objects, the grip applied to the objects, and the orientation of the objects. In each of three tasks in Experiment 1, participants evaluated the correctness of only one of the three information types (function, grip or orientation). Similar results were achieved with all three tasks: “correct” judgments were facilitated when the other dimensions were correct; however, “incorrect” judgments were facilitated when the other two dimensions were both correct and also when they were both incorrect. In Experiment 2, when participants attended to an action‐irrelevant feature (object color), there was no interaction between function, grip, and orientation. These results clearly indicate that action representations can be activated by retrieval of functional, manipulative, and spatial knowledge about objects, even though this is task‐irrelevant information.  相似文献

ObjectivesThe purpose of the present study was to identify the intricacies of verbalizations, gestures, and game outcome during competition.DesignThe behavioral research software Observer XT® using sequential analysis was used to analyze our data.MethodParticipants were 34 junior tennis players with a mean age of 13.68 (SD = 1.8). Youth players were observed during 17 matches using the Self-Talk and Gestures Rating Scale and were examined by a built-in application (Observer XT®) of mapping of verbalizations, gestures, and performance.ResultsSequences indicated negative verbalizations were the most frequently exhibited form of overt verbalizations, followed by positive and instructional verbalizations. Furthermore negative verbalizations for either the server or the receiver decreased the probability of winning a game and showed verbalizations from the server related to the receiver's verbalizations and game outcome, and vice versa.ConclusionsThe results shed light on how verbalizations and gestures interact differently according to the context, which may have important implications for research that has focused on verbalizations and has neglected gestures and contextualized performance in sport.  相似文献

This study examines the role of perceived shared understanding with regard to team performance, taking into account the motivational mechanisms (i.e., group potency and team effort) involved in this relationship and the moderating role of task routineness. Using a multisource approach and a team‐level design, we collected data from 101 teams (i.e., 381 members and their 101 immediate superiors) working in a Canadian public safety organization. The results support the mediating role of group potency and team effort in the relationship between perceived shared understanding and team performance. Moreover, the results show that the relationship between team effort and team performance is moderated by task routineness, such that this relationship is stronger when task routineness is high. On the whole, the findings of this study help to better understand why and under what circumstances perceived shared understanding may enhance team performance.  相似文献

成功的新产品开发是企业获取竞争优势的重要因素,但创新产品并非总能得到市场的接受,大多数的新产品扩散往往以失败告终。因此,业界和学界对新产品采纳问题进行了诸多探索。新产品采纳过程是指创新产品从被设计制造出来,到最终被消费者或潜在消费者认识和采用的过程。对相关研究综述发现:以Rogers创新扩散模型为依据,按采纳时间和特征的不同,新产品采纳者可以系统分为早期采纳者和晚期采纳者,二者之间主要从创新性、产品理解和易感性三个维度进行区分。具体来说,早期采纳者具有高创新性、高产品理解和低易感性;晚期采纳者具有低创新性、低产品理解和高易感性。在此基础上,我们探究了各维度下影响消费者新产品采纳的具体因素。未来研究可以从这三个维度出发,结合已有研究的不足以及当前环境、消费特点等进行拓展。  相似文献

言语理解是听者接受外部语音输入并且获得意义的心理过程。日常交流中,听觉言语理解受多尺度节律信息的影响,常见有韵律结构节律、语境节律、和说话者身体语言节律三方面外部节律。它们改变听者在言语理解中的音素判别、词汇感知以及言语可懂度等过程。内部节律表现为大脑内神经振荡,其能够表征外部言语输入在不同时间尺度下的层级特征。外部节律性刺激与内部神经活动的神经夹带能够优化大脑对言语刺激的处理,并受到听者自上而下的认知过程的调节进一步增强目标言语的内在表征。我们认为它可能是实现内外节律相互联系并共同影响言语理解的关键机制。对内外节律及其联系机制的揭示能够为理解言语这种在多层级时间尺度上具有结构规律的复杂序列提供了一个研究窗口。  相似文献

正确理解知情同意   总被引:11,自引:2,他引:11  
知情同意最初由美国于18世纪末19世纪初提出,随着社会不断进步,医学科学的不断发展,人们权力意识的不断增强,知情同意作为患者享有的一项权力,医务人员在医疗过程中应遵循的一条原则已日益到人们的关注。然而在现实的医疗实践中人们对这一的理解和认识还存在一定的偏差。正确理解,践行知情同意既是尊重患者的权利,贯彻“以病人为中心”的原则的保证,也能有效地保护医务人员的合法权益。  相似文献

Abstract

In this article, I reflect on theory of mind as a field (ToM), how it has developed over the years, and focally on the state of current research and theory. Having begun with preschoolers’ understanding of beliefs and desires, the field now includes research from infancy through late life, contributions and contributors from around the world, research on behavior, conversation, neural correlates, gene-environment contributions, evolution, and the social-behavioral antecedents and consequences of the unfolding trajectories of ToM understanding. Several topics in particular portray the current state of the art and my sense of where theory-of-mind research is likely to head in the near future: progressions of theory of mind achievement; cultural experiences plus experiential influences that shape developmental trajectories; developmental cognitive neuroscience; infant ToM insights; research on ToM developments beyond preschool, including children’s increasing interest in and wrestling with extraordinary minds, such as those of God and super-heroes.  相似文献

Abstract

This study assessed the effects of perceived need and nearness of the beneficiary and the chronological maturity of the benefactor on helping behavior. The relationship between verbal and objective measures of helping behavior, and the relationship between available resources and helping behavior were also explored. Indian undergraduates (N = 80 men) composed the sample. The results showed that greater perceived need and nearness of the beneficiary, as well as lesser chronological maturity of the benefactor, led to extending greater help. Verbal and objective measures of help did not generally correspond; however, the relationship between verbal and objective measures was modified by the perceived need and nearness of the beneficiary. Resource availability did not have any direct bearing on helping behavior.  相似文献
