动态基频(F0)轮廓有助于嘈杂环境下的言语识别,可以作为将目标语音从背景声中分离的知觉线索。本研究通过评估老年人与年轻人在言语掩蔽下聆听具有自然动态F0轮廓与对F0轮廓操作调节后的汉语语句的言语识别能力,探讨老龄化对F0轮廓线索在汉语言语识别去掩蔽作用中的影响。结果显示,在言语掩蔽下自然动态的F0轮廓比压扁或拉伸的F0轮廓更能帮助年轻人抵抗信息掩蔽识别目标言语;而老年人在言语掩蔽下却难以从动态F0轮廓线索中受益。研究结果揭示了老年人利用F0轮廓线索促进掩蔽下言语感知能力的老化特点。 相似文献

This study explored whether males and females differ in facial muscle activity when exposed to tone stimuli with different intensity. Males and females were repeatedly exposed to 95 dB and 75 dB 1000 Hz tones while their facial electromyographic (EMG) activity from corrugator and zygomatic muscle regions were measured. Skin conductance responses were also measured. It was found that 95 dB but not 75 dB tones evoked increased corrugator activity. This effect differed significantly between males and females. Thus, it was only females that reacted with a significant increased corrugator response to the high intensity tone. While facial responses differed between the sexes, the skin conductance response patterns did not. Consistent with previous research it is concluded that females are more facially expressive than are males. 相似文献

The purpose of this study is to explore whether subjects exposed to stimuli of facial expressions respond with facial electromyographic (EMG) reactions consistent with the hypothesis that facial expressions are contagious. This study further examines whether males and females differ in facial EMG intensity. Two experiments demonstrated that subjects responded with facial EMG activity over the corrugator supercilii, the zygomatic major , the lateral frontalis , the depressor supercilii , and the levator labii muscle regions to stimuli of sad, angry, fearful, surprised, disgusted and happy faces, that, to large extent, were consistent with the hypothesis that facial expressions are contagious. Aspects of gender differences reported in earlier studies were found, indicating a tendency for females to respond with more pronounced facial EMG intensity. 相似文献

在汉语中,副词是一种比较独特的词类,它没有具体形象的物体可作为理解支柱,因而儿童对它的掌握较晚。在各类副词中,5、6岁儿童对范围副词的理解最佳,时间副词次之,程度副词最差。三者的差异均有非常显著性意义。即使在每一类副词中,由于儿童概念发展的不均衡性,掌握的顺序也有先后。 相似文献

Tucker, Damarin and Messick proposed a base-free measure of change which involves the computation of residual scores that are uncorrelated with true scores on the pretest. The present note discusses this change measure and demonstrates that, because of an incorrect derivation by the authors, properties they attribute to (the coefficient for the regression of true scores from the second testing on true scores from the first testing) are, in fact, properties ofb, the ordinary regression coefficient. A correct derivation of the initial position—change correlation in terms of is obtained, and Tucker et al.'s discussion of the law of initial values is reconsidered.The preparation of this paper was supported by the Learning Research and Development Center supported in part as a research and development center by funds from the National Institute of Education. 相似文献

PurposeThe aim of this cross-sectional study was to explore the impact and experience of stuttering, and attitude to communication for female and male teenagers who stutter (TWS) in comparison with teenagers with no stutter (TWNS).MethodsThe Swedish version of the Overall Assessment of the Speaker’s Experience of Stuttering (OASES-T-S), was administered to 56 TWS, 13–17 years old (26 females, 30 males). An adapted version of OASES, Attitude to Speech and Communication (ASC), was administered to 233 TWNS. The impact scores were analyzed in relation to sex in TWS and TWNS.ResultsFemale TWS reported that stuttering had a greater impact on their life than it did on male TWS (on average 0.5 higher impact scores; Hedges’ g = 0.87). The differences did not seem to be caused by differences in severity of overt stuttering symptoms. Female and male TWS particularly differed on items related to difficulties in day-to-day communication and affective/behavioral reactions to stuttering. Such sex differences were not as pronounced among TWNS, suggesting that teenage women may be more vulnerable to the negative impact of stuttering than men the same age.ConclusionFemale teenagers report more negative experiences and a greater tendency to use avoidance strategies than male teenagers. 相似文献

相对于面对自己的人际冲突, 以独立自我为主的西方人在面对朋友的人际冲突时表现更智慧(所罗门悖论)。在以互依自我为主的中国人身上所罗门悖论是否会有不同特点?研究1通过在线平台招募中美两国被试, 随机分配到自我与朋友冲突组考察其智慧推理水平, 并考察自我类型的影响。对齐法与方差分析的结果均显示美国文化下朋友组智慧推理显著高于自我组, 而中国文化下两组差异不显著, 进一步分析发现中国文化下独立自我与冲突类型的交互项显著预测智慧推理。在此基础上, 研究2~4在中国文化背景下, 通过启动不同自我类型, 考察个体在自我或朋友冲突组中的智慧推理差异, 结果显示启动独立自我的朋友组显著高于自我组, 而启动互依自我的两组差异不显著。研究表明所罗门悖论可能只存在独立自我高的人身上, 并不具有普适性。可见心理学研究除了关注样本多样性问题外, 更需关注使用单一样本却默认结论具有文化普适性的研究者。 相似文献
