Evaluating self and partner physical attractiveness 总被引:1,自引:0,他引:1
This study used a novel questionnaire to examine ratings of self and partner physical attractiveness. Seventy-two men and 83 women estimated their own and their opposite-sex partner's overall physical attractiveness and the attractiveness of various body parts and measures. They also answered six simple questions concerning physical attractiveness. Results showed significant gender differences in self-estimates of overall facial attractiveness and upper body features. In general, and regardless of gender, participants rated their opposite-sex partners as being significantly more attractive than themselves. In addition, the results showed that body weight and facial attractiveness were the best predictors of overall physical attractiveness. Implications of these results in terms of social biases are considered. 相似文献

The authors examined relations between implicit and explicit Hope of Success (HS) and Fear of Failure (FF) and memory and liking for successful and unsuccessful peers. Implicit motives were expected to predict memory and explicit motives to predict liking of peers. Results from 106 American and 79 Singaporean students supported the implicit–explicit motive distinction as well as a link between HS and the successful peer and between FF and the unsuccessful peer. In both samples, explicit HS predicts liking while implicit HS predicts memory about the successful peer, and implicit FF predicts memory about the unsuccessful peer. Findings indicate achievement motives affect interest in and reaction towards peers and provide evidence for differential validity of implicit and explicit motives. 相似文献

由空气传递的声音刺激对胎儿呼吸及胎动的影响 总被引:1,自引:0,他引:1
采用回顾性研究方法考察了由空气传递的声音刺激对未足月与足月胎儿的呼吸性运动与胎动的影响.结果发现,胎儿通过呼吸运动的变化(如呼吸运动加速、减缓、停止/停顿等)及胎动来对外界刺激作出反应;而且这种反应在不同胎龄的胎儿间有显著的不同胎龄大的或足月的胎儿在有声音刺激条件下的呼吸运动变化比胎龄小的更多. 相似文献

准确解码语音中的情绪信息能让个体更好地适应社会环境, 此能力对新生儿和婴儿尤其重要, 因为人类刚出生时听觉系统远比视觉系统发育得完善。虽然已有研究表明5~7月龄的婴儿能分辨不同情绪种类的语音, 但目前对新生儿的研究还非常少。人类是否在出生时即具有分辨不同种类情绪性语音的能力?新生儿对情绪的加工是否存在正性或负性偏向?本文选用odd-ball范式考察高兴、恐惧、愤怒三种韵律性语音在1~6天龄新生儿大脑中诱发的事件相关电位。实验1直接对比三种情绪性条件, 发现新生儿大脑的额区(F3和F4电极点)可以区分情绪性语音的正负性, 正性(高兴)语音诱发的“失匹配反应”幅度明显大于负性(愤怒和恐惧)语音。实验2采用偏差和标准刺激反转的odd-ball范式, 证实了实验1的结果并非源于三种情绪语音物理属性的差异。本文的结果提示, 新生儿大脑可自动辨别正性与负性情绪语音, 但尚不能将愤怒和恐惧两种负性语音区分开来。更重要的是, 高兴语音比两种负性语音诱发了更大的失匹配反应, 这一结果首次从神经学层面(电生理指标)为新生儿情绪性语音加工的正性偏向提供了证据。 相似文献

采用音高识别与区分任务, 以汉语母语者、越南语母语者和俄语母语者为研究对象, 考察了两个语言加工层面的因素, 即声调范畴感知模式以及不同语言声调系统的复杂度差异对跨领域音乐音高感知的影响。结果发现: (1)汉语和越南语两组声调语言母语者听辨结果符合范畴感知模式, 而俄语母语者是连续感知。在语言和音乐两种刺激条件下, 声调语言母语者在范畴边界宽度、范畴内区分率、范畴间区分率以及区分峰度等指标上不存在显著差异。(2)汉语和越南语两组声调语言母语者的音乐音高区分任务结果差异不显著。实验结果表明: 在行为层面, 母语声调范畴感知模式可以迁移到音乐音高感知中, 但复杂声调系统并不能促进跨领域的音乐音高精细感知。实验结果从语言对音乐音高加工影响的角度支持了“共享论”。 相似文献

Event-related potential (ERP) has the potential to reveal the temporal neurophysiological dynamics of risk decision-making, but this potential has not been fully explored in previous studies. When predicting risk decision with ERPs, most studies focus on between-trial analysis that reflects feedback learning, while within-trial analysis that could directly link option assessment with behavioral output has been largely ignored. Suitable task design is crucial for applying within-trial prediction. In this study, we used a modified version of the classic Balloon Analogue Risk Task (BART). In each trial of the task, participants made multiple rounds of decisions between a risky option (pump up the balloon) and a safe option (cash out). Behavioral results show that as the level of economic risk increased, participants were less willing to make a risky decision and also needed a longer response time to do so. In general, the ERP results showed distinct characteristics compared with previous findings based on between-trial prediction, particularly about the role of the P1 component. Specifically, both the P1 (amplitude and latency) and P3 (amplitude) components evoked by current outcomes predicted subsequent decisions. We suggest that these findings indicate the importance of selective attention (indexed by the P1) and motivational functions (indexed by the P3), which may help clarify the cognitive mechanism of risk decision-making. The theoretical significance of these findings is discussed. 相似文献
