This study aimed to investigate the mechanisms underlying joke comprehension using event‐related potentials (ERPs). Fourteen healthy college students were presented with the context of a story without its joke or nonjoke ending, and then, when the story ending was presented, they were asked to make a funny/unfunny judgment about these endings. The behavioral results showed that there was no significant difference between funny and unfunny items, which meant that subjects could understand funny items as easily as unfunny ones. However, the ERP results showed that funny items initially elicited a more negative ERP deflection (N350–450) over frontocentral scalp regions. Dipole analysis localized the generators in the left temporal gyrus and the left medial frontal gyrus; it is suggested that these areas might be involved in detecting the incongruent element in joke comprehension. Between 600 and 800 ms, funny items subsequently elicited a more negative ERP deflection (N600–800) over frontocentral scalp regions and a more positive ERP deflection (P600–800) over posterior scalp regions. Dipole analysis localized the generator in the anterior cingulate cortex (ACC), an area involved in the breaking of mental set/expectation and the forming of novel associations. Finally, funny items elicited a more positive ERP deflection (P1250–1400) over anterior and posterior scalp regions. Dipole analysis localized the generators in the middle frontal gyrus and the fusiform gyrus, areas that might be related to the affective appreciation stage in joke process. Unlike that of Coulson and Kutas (2001), the present study might support the hypothesis of a three stage model of humor processing (humor detection, resolution of incongruity and humor appreciation). 相似文献

Terror management theory (TMT) proposes that self-esteem serves as a defense against the fear of death. Previous research has suggested that independent self-esteem is more salient in individualist cultures, whereas interdependent self-esteem is more salient in collectivist cultures. Thus, we hypothesized that in collectivist cultures, independent self-esteem would play a lesser role and interdependent self-esteem a greater role in terror management, compared to individualist cultures. The results support this prediction. In Study 1, personal self-esteem was negatively associated with death anxiety in samples from a Western (Austria) and Eastern (China) culture. However, both self-liking and self-competence were negatively associated with death anxiety among Austrian participants, but only self-liking (and not self-competence) was so among Chinese participants. Surprisingly, collective self-esteem was not significantly correlated with death anxiety. Yet, Study 2 showed that among Chinese participants, relational self-esteem was negatively associated with death anxiety. Study 3 examined the roles of relational versus personal self-esteem in moderating the effects of mortality salience on worldview defense. Among Chinese participants, relational rather than personal self-esteem increased the defense of worldviews centered on collectivist-Chinese values following mortality salience (Study 3a). In contrast, among Austrian participants, personal rather than relational self-esteem attenuated the effect of mortality salience on the defense of individualist-Austrian worldviews (Study 3b). Self-esteem serves a terror management function in both collectivist and individualist cultures; however, the differences between cultural worldviews determine the type of self-esteem that is more relevant to terror management processes. 相似文献

A highly supersaturated nanocrystalline Cr–25?wt% Zr alloy has been prepared by mechanical alloying of elemental crystalline powders. High-purity powders of Cr and Zr were milled for up to 20?h. The development of the microstructure was investigated by X-ray diffraction (XRD) and scanning electron microscopy. XRD patterns confirmed complete alloying of the Zr and Cr. The contribution of grain boundaries, the chemical potential of a solute atom induced by dislocations, and the elastic strain energy arising from the different sizes of Cr and Zr atoms have been calculated. The alloy formation is discussed with respect to the thermodynamic conditions of the material. The role of internal strains and stored enthalpies by dislocations on solute atoms is the major mechanical driving force for alloying and this is critically assessed in this article. 相似文献

本工作对两例先天性无痛症患者对于致痛性强刺激的知觉和反应进行了研究(例1女,10岁,例2男,13岁)。对照组为20例正常儿童,性别和年龄均与患儿相匹配。 结果:1),生活中痛:两例患儿均无(包括痛感觉和痛反应)。2)实验性痛:①痛感觉:两例患儿均无;②“痛”反应:例1有“痛”反应(脉搏和呼吸的变化以及行为反应明显,大致与正常儿童相似)。例2无“痛”反应(脉搏和呼吸的变化轻微,无行为反应,与正常儿童不同)。 由结果看来,先天性无痛症患者似乎可分为两种类型:不完全型(如同例1)和完全型(如同例2)。存在有“痛”反应而无痛感觉的无痛症患者。 本工作结果从另一侧面为痛的两成分学说提供了依据。 相似文献

单一被试实验与元分析技术 总被引:6,自引:0,他引:6
单一被试实验是特殊儿童心理与教育研究中的一种常用方法,但其外部效度往往受到质疑。运用元分析技术,能对大量单一被试实验研究结果进行定量综述,既可综合评价各研究的总效应,也能探讨、揭示出各类研究特征与相应研究结果的关系,这无疑为单一被试实验信度与效度的检验提供了更多的信息。本文结合国外一个较新的研究实例,对元分析技术的基本原理及分析步骤作简要介绍,并对单一被试实验与元分析技术的结合应用问题提出几点看法与建议。 相似文献

This paper studies the quality of life (QOL) that residents perceive in typical urban patterns in Ho Chi Minh City. Its major focus is to examine the improvement in the QOL through public intervention into the urban development process. There are four findings. First, moderate government intervention to correct market failures in areas where spontaneous urban development has occurred generates similar levels of satisfaction to areas with planned development. Second, urban planning is important as housing values and subjective satisfactions in planned areas are higher than those in spontaneous development areas. Third, redevelopment negatively affects the QOL in areas undergoing redevelopment. Finally, the contrast between the housing value and the subjective life satisfaction in spontaneous development areas undergoing redevelopment shows the problem of relying on the revealed preference assumption in traditional economics and the need for having alternative approaches. 相似文献

The main goal of the present study was to investigate how the degree of orthographic overlap between translation equivalents influences bilingual word recognition processes at different stages of reading development. Spanish–Basque bilingual children with ages ranging from 8 to 15 years were tested in an explicit translation recognition task with a large set of items. Critically, the degree of cross-language similarity (i.e. the cognate status) between the references and the correct targets was manipulated along a continuum in order to investigate how the reliance on cross-language orthographic overlap varies as a function of reading experience. Results showed that younger children were significantly more sensitive to the cognate status of words than older children while recognising translation equivalents, and that this difference did not depend on the speed of response of the participants. These results demonstrate that the influence of cross-language similarity progressively diminishes as a function of increased exposure to print together with the maturation of the mechanisms responsible for language interference suppression, as suggested by developmental models of bilingual lexical access. 相似文献
