Theorists have long postulated that facial properties such as emotion and sex are potent social stimuli that influence how individuals act. Yet extant scientific findings were mainly derived from investigations on the prompt motor response upon the presentation of affective stimuli, which were mostly delivered by means of pictures, videos, or text. A theoretical question remains unaddressed concerning how the perception of emotion and sex would modulate the dynamics of a continuous coordinated behaviour. Conceived in the framework of dynamical approach to interpersonal motor coordination, the present study aimed to address this question by adopting the coupled-oscillators paradigm. Twenty-one participants performed in-phase and anti-phase coordination with two avatars (male and female) displaying three emotional expressions (neutral, happy, and angry) at different frequencies (100% and 150% of the participant's preferred frequency) by executing horizontal rhythmic left-right oscillatory movements. Time to initiate movement (TIM), mean relative phase error (MnRP), and standard deviation of relative phase (SDRP) were calculated as indices of reaction time, deviation from the intended pattern of coordination, and coordination stability, respectively. Results showed that in anti-phase condition at 150% frequency, MnRP was lower with the angry and the female avatar. In addition, coordination was found to be more stable with the male avatar than the female one when both displaying neutral emotion. But the happy female avatar was found to elicit more stable coordination than the neutral female avatar. These results implied that individuals are more relaxed to coordinate with the female than the male, and the sensorimotor system becomes more flexible to coordinate with an angry person. It is also suggested social roles influence how people coordinate, and individuals attend more to interact with a happy female. In sum, the present study evidenced that social perception is embodied in the interactive behaviour during social interaction. 相似文献

In a large and detailed survey on the ethics of scientific coauthorship, members of the American Physical Society (APS) were
asked to judge the number of appropriate coauthors on his or her last published paper. Results show that the first or second
coauthor are more appropriate than later coauthors about whom there is equal and considerable doubt. The probability of any
third and subsequent coathors being judged as inappropriate is 23% for the APS guideline, 67% for the tighter guideline of
the International Committee of Medical Journal Editors, 59% if the guideline requires “direct contributions to scientific
discovery or invention”. Only 3% of respondents report having personally rejected an undeserving scientist who expected to
be an author on the last published paper. Respondents seem to be divided into two non-overlapping populations—those who report
no inappropriate coauthorship and those who have a more graduated view. 相似文献

This paper elaborates on discussions in Germany regarding some of the ethical and legal issues in the area of the use and
patenting of inventions involving human tissue. The issues discussed pertain to the benefits and problems regarding informed
consent and the issue of property rights as they relate to the donation of cells and tissue.
An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights
and Patents,” held in Warsaw, Poland on 23–24 April, 2004. 相似文献

Eighty percent of (commercial) genetically engineered seeds (GES) are designed only to resist herbicides. Letting farmers
use more chemicals, they cut labor costs. But developing nations say GES cause food shortages, unemployment, resistant weeds,
and extinction of native cultivars when “volunteers” drift nearby. While GES patents are reasonable, this paper argues many
patent policies are not. The paper surveys GE technology, outlines John Locke’s classic account of property rights, and argues
that current patent policies must be revised to take account of Lockean ethical constraints. After answering a key objection,
it provides concrete suggestions for implementing its ethical conclusions. 相似文献

人类工作记忆的事件相关电位研究 总被引:4,自引:1,他引:3
20世纪90年代以来,采用ERP技术对人类工作记忆脑机制的研究已取得大量的成果。主要探讨了特定类型的工作记忆(词语、空间、客体工作记忆)是否存在与其贮存、复述以及中央执行功能相关的特异性ERP成分,并从它们的时间进程及头皮分布来考察工作记忆的心理过程和神经机制。研究结果对于Baddeley的认知结构模型提供了有益的修正和补充。 相似文献

Baddeley和Hitch(1974)提出的工作记忆模型被广泛地应用数学运算领域,但是已有研究还缺乏系统性。首先,当前的研究主要集中在加法和乘法两种运算上,较少涉及减法、除法和更为抽象的代数运算;第二,研究者对语音环路和中央执行系统的作用进行了较深入的研究,但常常忽略视空间模板的作用;第三,工作记忆在数学运算过程中的作用具有动态性,它受到一些外部因素、数学任务内在因素和个体认知因素(如认知策略)的影响;第四,几乎有关研究都肯定中央执行系统在数学运算过程中的重要作用,然而负荷于中央执行系统的次级任务所含成分或功能的复杂性,导致我们很难确定中央执行系统如何作用于数学运算。对这些问题的研究将是未来可能的研究方向 相似文献

通过三个实验研究了属性的中心性程度对归纳推理的影响,结果表明,在归纳推理中存在属性中心性效应,中心属性比其他属性(次中心属性、再次中心属性)更能影响归纳推理。但属性中心性效应的出现受到了前提对象和结论对象相似性程度的制约,当前提对象和结论对象的相似程度高时,中心属性比其他属性更能影响归纳推理;随着相似性水平的降低,中心属性的归纳推理力度越来越弱,而次中心属性、再次中心属性的归纳推理力度则会依次表现出越来越强的趋势,到最后当前提对象和结论对象的属性完全不相似时,最次中心属性的归纳推理力度达到最高水平,而中心属性的归纳推理力度则降低到最低水平。由于再次中心属性的归纳推理力度的最高水平没有显著高于随机水平,而中心属性的归纳推理力度的最低水平却显著低于随机水平,因此,研究者认为,在前提对象和结论对象完全不相似的情况下,被试将确信不能采用中心属性来进行归纳推理的力度判断,而采用猜测的方式选择了肯定可以排除的项目之外的其他项目,这体现了具有不确定的归纳推理活动的过程的典型特征 相似文献

Richard Bandler 《Aggressive behavior》1975,1(3):261-266
Electrical stimulation of sites in the region of the ventromedial periaqueductal gray substance at the level of the midbrain–pontine junction was found to elicit a predatory attack by a cat upon a rat. The intensity of stimulation required to elicit the attack was three to four times less than that required to elicit similar behavior by hypothalamic stimulation. The results suggest that anatomically distinct regions of the periaqueductal gray substance are concerned with the regulation of predatory and affective forms of aggressive behavior. The difficulty in reconciling these results with the preeminent role assigned the hypothalamus in the organization of predatory behavior is also discussed. 相似文献
