Summary.-This study was designed to examine negative pragmatic transfer of the speech act of English compliments by Chinese who learn English as a foreign language and to estimate the correlation between the amount of negative pragmatic transfer and English proficiency of the Chinese learners. Frequencies of students' performance showed that both in the favored compliments and the response strategies, differences were evident between Chinese English learners and native English speakers. This indicated that Chinese learners had trouble with the "slang" or "idioms" of the target language and tended to transfer negatively their L1 pragmatic norms to their L2 communication. Moreover, the favored compliment response strategies used by two groups of Chinese learners--who had different levels of English proficiency--differed, and negative pragmatic transfer decreased as proficiency in English increased.  相似文献

It has been proposed that the medial prefrontal cortex (mPFC) is not necessary for delay eyeblink conditioning (DEC). Here, we investigated the involvement of the mPFC in DEC with a soft or loud tone as the conditioned stimulus (CS) by using electrolytic lesions or muscimol inactivation of guinea pig mPFC. Interestingly, when a soft tone was used as a CS, electrolytic lesions of the mPFC significantly retarded acquisition of the conditioned response (CR), and muscimol infusions into mPFC distinctly inhibited the acquisition and expression of CR, but had no significant effect on consolidation of well-learned CR. In contrast, both electrolytic lesions and muscimol inactivation of mPFC produced no significant deficits in the CR when a loud tone was used as the CS, or in the unconditioned response (UR) when a soft or loud tone was used as the CS. These results demonstrate that the mPFC is essential for the DEC with the soft tone CS but not for the DEC with the loud tone CS.  相似文献

There are three main hypotheses about mental representations of arithmetic facts: the independent representation hypothesis, the operand-order-free single-representation hypothesis, and the operand-order-specific single-representation hypothesis. The current study used electrical recordings of eye movements to examine the organization of arithmetic facts in long-term memory. Subjects were presented single-digit addition and multiplication problems and were asked to report the solutions. Analyses of the horizontal electrooculograph (HEOG) showed an operand order effect for multiplication in the time windows 150-300?ms (larger negative potentials for smaller operand first problems than for larger operand first ones). The operand order effect was reversed in the time windows from 400 to 1,000?ms (i.e., larger operand first problems had larger negative potentials than smaller operand first problems). For addition, larger operand first problems had larger negative potentials than smaller operand first in the series of time windows from 300 to 1,000?ms, but the effect was smaller than that for multiplication. These results confirmed the dissociated representation of addition and multiplication facts and were consistent with the prediction of the preferred operand-order-specific representation hypothesis.  相似文献

社会学家贝拉(Robert Bellah)在其颇具影响力"宗教演化"的文章中,根据广泛的人类经验提出了一个检验文化和宗教互动的模式。贝拉在其雄心勃勃的计划中还是保持相当的谦虚,他警觉到其所用的例证源于历史文献,而模式本身则不是历史。模式是"一种思考的工具":一个用来指导思考的理论性框架,而非基于田野调查的经验性描述。在我们下面的讨论中,我们将使用贝拉的"思考工具"的基本模式,将包括来自贝拉本人和其他宗教学者研究中的一些修正和补充的内容。  相似文献

初中生心理健康问题的检出率在诸多研究中存在很大分歧, 未能为心理健康政策制定和服务体系建设提供充分依据。为明确心理健康问题的整体检出率并澄清其影响因素, 对2010~2020年检索到的文献进行了元分析。结果发现, 初中生面临不同程度的心理健康问题, 其中焦虑、抑郁和自我伤害检出率排在前三位; 初中生心理健康问题随年代发展呈恶化趋势, 其中焦虑和自杀企图尤为明显; 初中生心理健康问题检出率饱受测量工具、检出标准和检出时间不统一的影响; 初中生心理健康问题检出率整体上随年级而增加, 其中焦虑尤为明显; 女生的心理健康问题检出率高于男生, 自杀尤为明显; 中西部地区的初中生比东北和东部地区更容易出现心理健康问题, 尤其是焦虑和自我伤害。未来应立足中国大地研制科学的测量工具和筛查标准并建立心理健康动态监测体系和学校心理健康服务体系。  相似文献

成瘾过程伴随着一系列心理和脑机能的改变.已有研究表明,海洛因成瘾者存在对情绪刺激的加工缺陷.这些认知变化被认为与成瘾者脑内“奖赏系统”功能紊乱有关,但这种认知功能缺陷是否随着戒断进行而有所恢复还未得到明确结论.该研究采用ERP技术,记录了控制组、短期戒断组、中期戒断组和长期戒断组被试在情绪刺激加工过程中的神经电活动.结果发现,与中性刺激相比,长期组与控制组一致,正、负性刺激诱发被试更大的P300和SPW平均波幅,两类情绪刺激诱发的SPW波幅差异不显著;中期组被试的正性和负性刺激诱发的P300和SPW波幅都显著大于中性刺激,且负性刺激诱发的两成分的波幅显著大于正性刺激;短期组被试的负性刺激引起的P300和SPW波幅显著大于中性和正性刺激,但是正性和中性刺激诱发的P300或SPW波幅之间差异不显著.结果表明,随着戒断进行,海洛因戒断者情绪加工能力有所改善,主要表现在对正性情绪刺激加工能力的恢复.  相似文献

探讨预防性气管切开在伴慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)且长期大量吸烟的上段食管癌术后的应用,分析其对患者术后肺部感染、低氧血症、心律失常的影响.回顾性分析我科2011年6月~2013年1月伴有COPD及长期大量吸烟的上段食管癌行手术切除颈部吻合的病例,并分为预防性气管切开组和非预防性气管切开组.统计并分析两组术后肺部感染、低氧血症、心律失常等并发症的发生情况.结果对于上段食管癌行根治手术的患者,尤其是伴有长期大量吸烟及COPD的患者来说,预防性气管切开可以起到预防术后呼吸道并发症的发生,并能减少术后心律失常的发生的作用,其可以做为上段食管癌重症患者的一种预防围手术期并发症的方式.  相似文献

We conducted a field study to investigate how goal orientation traits and two variants of self-efficacy affect the goal-setting process and, in turn, performance. Participants were 255 college students enrolled in psychology or biochemistry courses at a large east-coast university in the People's Republic of China. Structural equation modeling analyses largely supported the argument that self-efficacy defined as a trait interacts with goal orientation traits, whereas self-efficacy defined as a state mediates the trait effects in the goal-setting process. The specific Trait × Trait interaction form was consistent with Dweck's original goal orientation theory and Brockner's behavior plasticity theory.  相似文献

This study investigated the relations between student perceptions of support and student willingness to seek help for bullying and threats of violence in a sample of 7318 ninth-grade students from 291 high schools who participated in the Virginia High School Safety Study. Hierarchical linear modeling indicated that students who perceived their teachers and other school staff to be supportive were more likely to endorse positive attitudes toward seeking help for bullying and threats of violence. In schools with more perceived support, there was less of a discrepancy in help-seeking attitudes between girls and boys. Findings suggest that efforts by school staff to provide a supportive climate are a potentially valuable strategy for engaging students in the prevention of bullying and threats of violence.  相似文献
