神经科学家F.Pulvermüller根据Hebb的“细胞群集”学说和相关性学习原理构建的“语言表征的神经生物学理论”首次试图基于皮层功能网络来解释语音、词汇和句法在大脑皮层的表征机制,不仅能较好地描述语言活动中经典语言脑区与其它参与活动脑区的相互关系,也对语言加工的大脑功能偏侧化与整合现象作了合适的说明。本文介绍了这一理论的主要观点和研究资料,并提出了一些尚需进一步研究的问题。 相似文献

An understanding of the differences in the ways in which self-efficacy and interest influence boys’ and girls’ intentions
to continue enrollment in mathematics courses may provide insight into how to encourage continued mathematics enrollment for
all students. Two competing theoretical models of mathematics self-efficacy and interest in predicting students’ enrollment
intentions and achievement were evaluated separately across samples of middle level boys and girls. One model was empirically
supported for both groups and indicated the independent influence of self-efficacy and interest in predicting enrollment intentions.
Multi-group analyses revealed that self-efficacy’s influence in enrollment intentions and achievement was significantly stronger
for boys than for girls, and interest was significantly more important in the prediction of enrollment intentions for girls
than for boys. 相似文献

In today’s creative economy, individuals generally have not been regarded as reservoirs of creativity who yield sustainable growth in hypercompetitive markets. Individuals rely on IT support to reduce clerical loads and enhance the effectiveness and efficiency of their work as well. When they work in teams, they also require self-confidence and the need for cognition to promote their individual creativity. Data were derived from the members of a large system integration company in South Korea (N = 256, 50 teams). As the study considered variables at both the team and individual levels, we adopted a multilevel analysis approach. We found that individual self-confidence, which indicates the degree of perceived possibility of success at a task, and the need for cognition, the intrinsic motivation to engage in and enjoy thinking, affected individual creativity significantly. Further, the degree of IT support, the team-level variable, had a significant effect on individual creativity. The degree of IT support did not have a significant effect on the relationship between self-confidence and individual creativity, but did have a moderating effect that weakened the relationship between the need for cognition and individual creativity. These findings have implications for theories of members’ creativity in organizations. 相似文献

采用空间启动范式考察二语情绪概念理解中是否激活空间信息, 即是否存在空间隐喻。实验1探讨单通道二语情绪概念理解中的空间隐喻, 实验2则探讨跨通道二语情绪概念理解中的空间隐喻。实验1中让32名母语为汉语的汉-英双语者先看一个英文情绪词, 接着进行视觉空间位置判断, 最后再让被试判断之前呈现的情绪词是积极词还是消极词。实验2中40名母语为汉语的汉-英双语者完成跟实验1类似的任务, 不同之处为英文情绪词以听觉形式呈现。两个实验的结果表明, 跨语言和跨通道的情绪词的空间隐喻受到空间位置方向的影响。垂直位置方向上, 二语情绪词在单通道和跨通道中都表现出了空间隐喻; 水平位置方向上, 二语情绪词没有表现出空间隐喻。该结果说明了情绪概念的空间隐喻会受到个体经验的影响, 进一步支持了知觉符号理论。 相似文献

Skin-transmitted pathogens have threatened humans since ancient times. We investigated whether skin-transmitted pathogens were a subclass of disgust stimuli that evoked an emotional response that was related to, but distinct from, disgust and fear. We labelled this response “the heebie jeebies”. In Study 1, coding of 76 participants’ experiences of disgust, fear, and the heebie jeebies showed that the heebie jeebies was elicited by unique stimuli which produced skin-crawling sensations and an urge to protect the skin. In Experiment 2,350 participants’ responses to skin-transmitted pathogen, fear-inducing, and disgust-inducing vignettes showed that the vignettes elicited sensations and urges which loaded onto heebie jeebies, fear, and disgust factors, respectively. Experiment 3 largely replicated findings from Experiment 2 using video stimuli (178 participants). Results are consistent with the notion that skin-transmitted pathogens are a subclass of disgust stimuli which motivate behaviours that are functionally consistent with disgust yet qualitatively distinct. 相似文献

Although domestic dogs can respond to many facial cues displayed by other dogs and humans, it remains unclear whether they
can differentiate individual dogs or humans based on facial cues alone and, if so, whether they would demonstrate the face
inversion effect, a behavioural hallmark commonly used in primates to differentiate face processing from object processing.
In this study, we first established the applicability of the visual paired comparison (VPC or preferential looking) procedure
for dogs using a simple object discrimination task with 2D pictures. The animals demonstrated a clear looking preference for
novel objects when simultaneously presented with prior-exposed familiar objects. We then adopted this VPC procedure to assess
their face discrimination and inversion responses. Dogs showed a deviation from random behaviour, indicating discrimination
capability when inspecting upright dog faces, human faces and object images; but the pattern of viewing preference was dependent
upon image category. They directed longer viewing time at novel (vs. familiar) human faces and objects, but not at dog faces,
instead, a longer viewing time at familiar (vs. novel) dog faces was observed. No significant looking preference was detected
for inverted images regardless of image category. Our results indicate that domestic dogs can use facial cues alone to differentiate
individual dogs and humans and that they exhibit a non-specific inversion response. In addition, the discrimination response
by dogs of human and dog faces appears to differ with the type of face involved. 相似文献
