Psynteract: A flexible,cross-platform,open framework for interactive experiments

We introduce a novel platform for interactive studies, that is, any form of study in which participants’ experiences depend not only on their own responses, but also on those of other participants who complete the same study in parallel, for example a prisoner’s dilemma or an ultimatum game. The software thus especially serves the rapidly growing field of strategic interaction research within psychology and behavioral economics. In contrast to all available software packages, our platform does not handle stimulus display and response collection itself. Instead, we provide a mechanism to extend existing experimental software to incorporate interactive functionality. This approach allows us to draw upon the capabilities already available, such as accuracy of temporal measurement, integration with auxiliary hardware such as eye-trackers or (neuro-)physiological apparatus, and recent advances in experimental software, for example capturing response dynamics through mouse-tracking. Through integration with OpenSesame, an open-source graphical experiment builder, studies can be assembled via a drag-and-drop interface requiring little or no further programming skills. In addition, by using the same communication mechanism across software packages, we also enable interoperability between systems. Our source code, which provides support for all major operating systems and several popular experimental packages, can be freely used and distributed under an open source license. The communication protocols underlying its functionality are also well documented and easily adapted to further platforms. Code and documentation are available at https://github.com/psynteract/.     

表象对成语记忆影响的实验研究

通过混合实验设计探讨表象对成语记忆的影响.实验结果表明,据成语形成图厕形式的表象能提高图画命名中外显记忆的成绩,显著提高内隐记忆的成绩,尤其是低透明度成语的内隐记忆成绩;但在成语补全中,对两种记忆均没有显著影响.可见.表象同时具有概念加工和知觉加工的性质,表象作用对所形成的表象的形式与测试任务的一致性程度敏感.     

The roots of human altruism

Human infants as young as 14 to 18 months of age help others attain their goals, for example, by helping them to fetch out‐of‐reach objects or opening cabinets for them. They do this irrespective of any reward from adults (indeed external rewards undermine the tendency), and very likely with no concern for such things as reciprocation and reputation, which serve to maintain altruism in older children and adults. Humans' nearest primate relatives, chimpanzees, also help others instrumentally without concrete rewards. These results suggest that human infants are naturally altruistic, and as ontogeny proceeds and they must deal more independently with a wider range of social contexts, socialization and feedback from social interactions with others become important mediators of these initial altruistic tendencies.     

聋生汉字加工的自由回忆与词序位置记忆实验研究

本研究采用韵母相同、声母相同、音异形似和音同形似四类汉字字组,对使用手语聋生、使用口语聋生和听力正常大学生进行了自由回忆和词序位置记忆两个实验。结果表明,聋生不论在汉字字组的自由回忆中还是在汉字次序信息的记忆中,对汉字的记忆效果不仅都与字组类型有关,而且都受到了语音干扰,存在语音混淆现象。这就证明,聋生在汉字加工过程中使用了语音编码,语音编码在聋生汉字加工过程中确实起到了非常重要的作用。     

The dissemination of critical,unshared information in decision‐making groups: the effects of pre‐discussion dissent

Previous research in group decision making has found that in situations of a hidden profile (i.e. the best choice alternative is hidden from individual members as they consider their pre‐discussion information), unshared information is disproportionately neglected and sub‐optimal group choices are highly likely. In an experimental study, three‐person groups decided which of three candidates to select for a professorial appointment. We hypothesised that minority dissent in pre‐discussion preferences improves the consideration of unshared information in groups and increases the discovery rate of hidden profiles. As predicted, consideration of unshared information increased with minority dissent. The expectation of an improvement of group decision quality was partially supported. In diversity groups (i.e. each member prefers a different alternative) consideration of unshared information and group decision quality was significantly higher than in simple minority groups. Results are discussed in the light of theories of minority influence. The benefits of using the hidden profile paradigm with minority and diversity groups for theory development in the area of group decision making are highlighted.

Liberal Nationalism and Cosmopolitan Justice

Many liberals have argued that a cosmopolitan perspective on global justice follows from the basic liberal principles of justice. Yet, increasingly, it is also said that intrinsic to liberalism is a doctrine of nationalism. This raises a potential problem for the liberal defense of cosmopolitan justice as it is commonly believed that nationalism and cosmopolitanism are conflicting ideals. If this is correct, there appears to be a serious tension within liberal philosophy itself, between its cosmopolitan aspiration on the one hand, and its nationalist agenda on the other. I argue, however, that this alleged conflict between liberal nationalism and cosmopolitan liberalism disappears once we get clear on the scope and goals of cosmopolitan justice and the parameters of liberal nationalism. Liberal nationalism and cosmopolitan global justice, properly understood, are mutually compatible ideals.     

中学生责任心的理论构建研究

责任心是一种自觉地把分内的事做好的重要人格特质,具有多维度多层次的心理结构.参照有关文献建立了中学生责任心结构模型,编制出我国中学生责任心量表.通过对747名中学生的探索性因素分析和1009名中学生的验证性因素分析,结果表明该量表结构清晰,信度和效度较好,可以作为评鉴中学生责任心的有效工具.     

情绪调节策略对推理的影响

研究使用两种推理题作为实验材料.比较了负性情绪诱发状态下情绪调节策略使用与否以及不同情绪调节策略对推理的影响.结果发现,认知重评组的成绩好于表达抑制组和无调节组,存在显著差异;表达抑制组与无调节组之间不存在差异.此外,在表达抑制组上,男生的图形推理成绩好于女生,存在显著的性别差异.因此,个体不同推理任务的成绩与是否使用调节策略、使用什么策略及性别有关.     

What is the shape of developmental change?

Developmental trajectories provide the empirical foundation for theories about change processes during development. However, the ability to distinguish among alternative trajectories depends on how frequently observations are sampled. This study used real behavioral data, with real patterns of variability, to examine the effects of sampling at different intervals on characterization of the underlying trajectory. Data were derived from a set of 32 infant motor skills indexed daily during the first 18 months. Larger sampling intervals (2-31 days) were simulated by systematically removing observations from the daily data and interpolating over the gaps. Infrequent sampling caused decreasing sensitivity to fluctuations in the daily data: Variable trajectories erroneously appeared as step functions, and estimates of onset ages were increasingly off target. Sensitivity to variation decreased as an inverse power function of sampling interval, resulting in severe degradation of the trajectory with intervals longer than 7 days. These findings suggest that sampling rates typically used by developmental researchers may be inadequate to accurately depict patterns of variability and the shape of developmental change. Inadequate sampling regimes therefore may seriously compromise theories of development.     

Continual training of attentional bias in social anxiety

Using the dot-probe paradigm, it has been shown that high social anxiety is associated with an attentional bias toward negative information. In the present study, individuals with high social anxiety were divided into two groups randomly. One group was the attentional bias training group (Group T), and the other was the control group (Group C). For Group T, 7 days' continuous training of attentional bias was conducted using the dot-probe paradigm to make socially anxious individuals focus more on positive face pictures. The results showed that the training was effective in changing attentional bias in Group T. Scores of the Social Interaction Anxiety Scale (SIAS) in Group T were reduced compared to Group C, while the scores of Social Phobia Scale (SPS) and scores of Negative Evaluation Scale (FNE) showed no difference between the two groups, which suggested a limited reduction of social anxiety.
