Mental visualization of objects from cross-sectional images

We extended the classic anorthoscopic viewing procedure to test a model of visualization of 3D structures from 2D cross-sections. Four experiments were conducted to examine key processes described in the model, localizing cross-sections within a common frame of reference and spatiotemporal integration of cross sections into a hierarchical object representation. Participants used a hand-held device to reveal a hidden object as a sequence of cross-sectional images. The process of localization was manipulated by contrasting two displays, in situ vs. ex situ, which differed in whether cross sections were presented at their source locations or displaced to a remote screen. The process of integration was manipulated by varying the structural complexity of target objects and their components. Experiments 1 and 2 demonstrated visualization of 2D and 3D line-segment objects and verified predictions about display and complexity effects. In Experiments 3 and 4, the visualized forms were familiar letters and numbers. Errors and orientation effects showed that displacing cross-sectional images to a remote display (ex situ viewing) impeded the ability to determine spatial relationships among pattern components, a failure of integration at the object level.     

马克思的社会形态思想再探——基于《政治经济学批判〈序言〉》中社会经济形态演进论述的分析

作为历史唯物主义的重要内容,社会形态思想是对社会历史的形成、发展及其运动的内在规律的深刻揭示和整体阐发,正确把握社会形态思想中的社会历史分期和演进的规律具有十分重要的意义。本文通过对学界关于《政治经济学批判〈序言〉》中社会经济形态演进论述的理解所形成的“三形态说”和“五形态说”争论的梳理和辨析,进一步探讨马克思的社会形态思想,认为马克思在《政治经济学批判〈序言〉》中的相关论述既指出了社会形态演进的基础和发展方向,又隐含着一定社会历史中人的发展状态的内容,同时内蕴分析社会形态的基本原则。     

居危思变?工作不安全感对创新行为的差异化影响?

企业往往在员工管理和组织创新上处于“两难困境”——难以提供稳定工作但又不得不依赖员工实现组织创新, 这就使得研究员工工作不安全感对创新行为的影响至关重要。企业员工遭遇不同环境威胁带来的工作不安全感时, 创新行为存在差异。本文在威胁焦点下深化工作不安全感概念, 并基于“以变量为中心”和“以人为中心”的研究思路, 探讨其对创新行为的差异化影响过程。首先, 结合环境威胁来源与主观感知, 把工作不安全感分为岗位焦点工作不安全感和人员焦点工作不安全感两个维度, 并将编制测量量表。其次, 期望运用纵向研究设计, 通过分析多时点的员工-主管配对数据, 基于情境调节焦点和工作激情的链式中介作用, 来揭示岗位焦点工作不安全感对创新行为的负向影响, 以及人员焦点工作不安全感对创新行为的倒U型影响。最后, 将采取“以人为中心”的研究思路, 运用潜在剖面分析方法探讨工作不安全感潜在类型及其对创新行为的影响。研究结果将有助于推进工作不安全感的概念和效用研究, 也为企业如何有效促进创新提供对策建议。

When expressing forgiveness backfires in the workplace: victim power moderates the effect of expressing forgiveness on transgressor compliance

Expressing (vs. withholding) forgiveness is often promoted as a beneficial response for victims. In the present research, we argue that withholding (vs. expressing) forgiveness can also be beneficial to victims by stimulating subsequent transgressor compliance – a response that is valuable in restoring the victim’s needs for control. Based on deterrence theory, we argue that a victim’s withheld (vs. expressed) forgiveness promotes transgressor compliance when the victim has low power, relative to the transgressor. This is because withheld (vs. expressed) forgiveness from a low-power victim elicits transgressor fear. On the other hand, because people are fearful of high-power actors, high-power victims can expect high levels of compliance from a transgressor, regardless of whether they express forgiveness or not. A critical incidents survey (Study 1) and an autobiographic recall study (Study 2) among employees, as well as a laboratory experiment among business students (Study 3), support these predictions. These studies are among the first to reveal that withholding forgiveness can be beneficial for low-power victims in a hierarchical context – ironically, a context in which offering forgiveness is often expected.     

内隐多效性选择的ERP证据

采用事件相关电位技术,考察内隐多效性选择及其神经机制。被试的任务是认真观看配对的纯色图片刺激,并进行分类按键反应。实验结果发现,在P2上,积极启动刺激比对照刺激激发了更大的P2波幅; 对比对照刺激,积极启动刺激在左脑、大脑中部和后脑诱发了更大的P2波幅,其中右脑的效应最大。在N2上,积极启动刺激比对照刺激激发了更小的N2波幅; 对比对照刺激,积极启动刺激在左脑、大脑中部和后脑诱发了更小的N2波幅,其中右脑的效应最大。在P3上,积极启动刺激比对照刺激激发了更大的P3波幅; 对比对照刺激,积极启动刺激在左脑、大脑中部和后脑诱发了更大的P3波幅,其中右脑的效应最大。研究结果表明当外显目标与内隐目标同时被呈现时,被试趋向于做多效性选择,这可能表明无意识信息加工具有相当大的权重。且右后部脑区可能是加工多效性刺激的核心和关键区域,P3成分可能反应了内隐多效性选择的精细加工过程,能够作为内隐多效性选择的有效的ERPs指标。     

自我损耗、情绪动机对冲动决策的影响

以大学生为被试,探讨自我损耗、情绪动机对冲动决策的影响。采用2×2×2的混合实验设计,组内变量为自我损耗,组间变量为情绪动机方向和强度,使用双任务范式操作自我损耗,使用情绪动机图片启动被试的情绪动机,使用延迟折扣任务的指标k值测量冲动决策。结果发现,高趋近动机的k值大于低趋近动机,高回避动机的k值大于低回避动机。结果表明,自我损耗、情绪动机对冲动决策有明显影响。     

家庭功能与青少年消极冒险行为的关系:一个有调节的中介模型

为探讨家庭功能影响青少年消极冒险行为的作用机制及条件,采用青少年冒险行为问卷、家庭功能问卷、自尊问卷、同伴群体特征问卷对山东省日照市940名初高中学生进行调查。结果发现:(1)家庭功能不良不仅可直接预测青少年更多的消极冒险行为,而且也可通过使青少年交往更多不良同伴进而使其冒险行为进一步增多;(2)不良同伴交往对青少年消极冒险行为的预测受到个体自尊的调节。低自尊个体更容易受到不良同伴交往的影响而发生更多的消极冒险行为,表现出两风险因素的叠加效应。研究结果提示,家庭是青少年健康成长的基础,家庭功能不良可使青少年适应不良,塑造良好的同伴环境、培养良好的自我素质或可降低这一风险。     

Counterfactual comparison modulates fairness consideration in the mini‐ultimatum game: An event‐related potentials study

Existing literature on the mini‐ultimatum game indicates that counterfactual comparison between chosen and unchosen alternatives is of great importance for individual's fairness consideration. However, it is still unclear how counterfactual comparison influences the electrophysiological responses to unfair chosen offers. In conjunction with event‐related potentials’ (ERPs) technique, the current study aimed to explore the issue by employing a modified version of the mini‐ultimatum game where a fixed set of two alternatives (unfair offer vs. fair alternative, unfair vs. hyperfair alternative, unfair offer vs. hyperunfair alternative) was presented before the chosen offer. The behavioral results showed that participants were more likely to accept unfair chosen offers when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. The ERPs results showed that the feedback‐related negativity (FRN) elicited by unfair chosen offers was insensitive to the type of unchosen alternative when correcting for possible overlap with other components. In contrast, unfair chosen offers elicited larger P300 amplitudes when the unchosen alternative was hyperunfair than when the unchosen alternative was fair or hyperfair. These findings suggest that counterfactual comparison may take effect at later stages of fairness consideration as reflected by the P300.
