Simon效应及其反转现象作用机制的研究

研究运用任务干扰的实验范式,试图从探讨刺激出现的空间位置与反应效果之间的关系来推测Simon效应及其反转现象的作用机制。结果表明:(1)当相关刺激-反应匹配不相容时,颜色刺激在左、右位置呈现,当明显标记反应键时,出现Simon效应的反转。(2)当手指遮住反应键的标记时,没有反转。(3)当颜色刺激在中央位置,声音在左、右耳发生时,没有反转。说明显示-控制排列对应性是产生Simon效应反转的最重要因素,逻辑再编码只起到次要的作用。     

When competition merges people's behavior: Interdependency activates shared action representations

Previous research suggests that friendly, cooperative situations cause one to integrate a co-actor's actions into one's own action system. Departing from an interdependency perspective, we predict the activation of shared action representations even in hostile, competitive situations as a result of attending to the intentions of the co-actor. To test this, in Experiment 1 we manipulated the interdependency between actor and co-actor in a joint Simon task and observed a stronger activation of shared action representations in a cooperative as well as competitive context compared to an independent context. Experiment 2 replicated the competitive context effect on activation of shared action representations and provided additional evidence for the mediating role of attending to others’ intentions by taking into account the individual tendency to attend to others’ intentions. Together, our findings suggest that interdependency merges people's behavior even in competitive contexts, which we argue encourage actors to attend to others’ intentions.     

On the Symbiosis of Science and Religion: A Jewish Perspective

Three theses are explored, the first two historical and the third philosophical-theological: (1) throughout most of the history ofWestern civilization, science and religion have been closely connected with each other, and each has benefited from the connection; (2) the belief that science and religion have always been in conflict is not based on the actual history of either set of institutions; and (3) structurally a relationship between the two institutions is in the interest of both. By religion here I mean specifically, but not exclusively, Judaism.     

权力不稳定性对权力效应的逆转作用

摘 要 基于权力的趋近-抑制理论，本研究探讨权力不稳定性对权力效应产生逆转作用以及权力动机对这一逆转作用的影响。实验采用角色扮演法和真实任务角色来操纵被试的权力水平和权力不稳定性，以赌博任务中的冒险行为和金钱分配任务中的趋利行为来测量被试的权力趋近/抑制效应。结果发现：权力稳定条件下，高权力被试比低权力被试表现出更多的冒险行为和趋利行为；权力不稳定条件下则相反，低权力被试比高权力被试表现出更多的冒险行为和趋利行为。权力不稳定条件下高权力动机的高权力者相比低权力动机的高权力者倾向给自己分配更少的金额数，表现出更为明显的抑制倾向；而高权力动机的低权力者相比低权力动机的低权力者倾向于提出更高要求的金额数，表现出更为明显的趋近倾向。该研究证实了权力不稳定性对权力效应的逆转作用，而权力动机对这一逆转作用起到增强趋势。     

排除“每个人都优于平均水平”机制影响的自我提升研究

采用优于平均效应、自我服务归因偏向和内隐测验三种方法测量中国大学生的自我提升,并在前两种方法中考虑了EBTA机制的影响,以探讨中国人的自我提升动机及其表现形式。结果发现：EBTA机制影响显著;排除EBTA机制的影响后,大学生依然存在优于平均效应和自我服务归因偏向;大学生存在内隐自我提升值;内隐自我提升值与外显自我提升值之间存在显著正相关。

综述了返回抑制(Inhibition of return,IOR)出现时程机制的三因素理论内容,支持该理论的实验证据,以及对理论的质疑和发展。该理论认为空间定向收益、出现检测缺失和空间选择收益三个因素共同决定了IOR出现的时程及机制。研究者通过操控任务加工水平或将实验范式相结合的方式对三因素理论提出了质疑和发展。许多关键问题如三个因素存在的认知神经科学证据、出现检测缺失和空间选择收益发挥作用的方式等是未来研究的重点和方向。     

Out with .05, in with Replication and Measurement: Isolating and Working with the Particular Effect Sizes that are Troublesome for Inferential Statistics

It is difficult to obtain adequate power to test a small effect size with a set criterion alpha of 0.05. Probably an inferential test will indicate non-statistical significance and not be published. Rarely, statistical significance will be obtained, and an exaggerated effect size calculated and reported. Accepting all inferential probabilities and associated effect sizes could solve exaggeration problems. Graphs, generated through Monte Carlo methods, are presented to illustrate this. The first graph presents effect sizes (Cohen's d) as lines from 1 to 0 with probabilities on the Y axis and the number of measures on the X axis. This graph shows effect sizes of .5 or less should yield non-significance with sample sizes below 120 measures. The other graphs show results with as many as 10 small sample size replications. There is a convergence of means with the effect size as sample size increases and measurement accuracy emerges.     

Uncovering effects of self-control and stimulus-driven action selection on the sense of agency

The sense of agency refers to feelings of causing one’s own action and resulting effect. Previous research indicates that voluntary action selection is an important factor in shaping the sense of agency. Whereas the volitional nature of the sense of agency is well documented, the present study examined whether agency is modulated when action selection shifts from self-control to a more automatic stimulus-driven process. Seventy-two participants performed an auditory Simon task including congruent and incongruent trials to generate automatic stimulus-driven vs. more self-control driven action, respectively. Responses in the Simon task produced a tone and agency was assessed with the intentional binding task – an implicit measure of agency. Results showed a Simon effect and temporal binding effect. However, temporal binding was independent of congruency. These findings suggest that temporal binding, a window to the sense of agency, emerges for both automatic stimulus-driven actions and self-controlled actions.     

The interaction between emotion and executive control: Comparison between visual,auditory, and tactile modalities

The reciprocal connections between emotion and attention are vital for adaptive behaviour. Previous results demonstrated that the behavioural effects of emotional stimuli on performance are attenuated when executive control is recruited. The current research studied whether this attenuation is modality dependent. In two experiments, negative and neutral pictures were presented shortly before a visual, tactile, or auditory target in a Simon task. All three modalities demonstrated a Simon effect, a conflict adaptation effect, and an emotional interference effect. However, the interaction between picture valence and Simon congruency was found only in the visual task. Specifically, when the Simon target was visual, emotional interference was reduced during incongruent compared to congruent trials. These findings suggest that although the control-related effects observed in the Simon tasks are not modality dependent, the link between emotion and executive control is modality dependent. Presumably, this link occurs only when the emotional stimulus and the target are presented in the same modality.
