敬畏对跨期选择的影响：时间洞察力和时距敏感度的作用

本研究考察了情绪(敬畏、愉悦和中性)对跨期选择的影响机制,以及时距敏感度和时间洞察力在其中的作用。结果显示：(1)相比中性,敬畏情绪下个体的折扣率更大;(2)相比中性,敬畏情绪下折扣率降幅更大;(3)对于未来取向者,敬畏情绪下折扣率比中性条件下更大;(4)对于现在取向者,敬畏情绪下折扣率降幅比中性条件下更大。结果表明,敬畏情绪通过未来时距的敏感度影响跨期选择偏好,使个体更加偏好延迟奖赏,同时,个体的时间取向在其中起调节作用。     

视听时、空一致性对Pip-and-Pop效应的影响

多感觉整合遵循空间原则和时间原则,有研究表明Pip-and-Pop效应产生的原因是多感觉整合,那么Pip-and-Pop效应是否同样遵循空间原则和时间原则呢？本研究采用动态视觉搜索范式,通过两个眼动实验考察空间一致性(实验1)和时间一致性(实验2)对Pip-and-Pop效应的影响。结果发现：(1)当视觉目标颜色变化伴随一个同侧的听觉刺激时所产生的Pip-and-Pop效应最大,对侧条件没有发现Pip-and-Pop效应。(2)视听刺激同时呈现所产生的Pip-and-Pop效应最大,随视听刺激呈现时间间隔的增加Pip-and-Pop效应逐渐减弱直至消失。结果表明,视听时、空一致性对Pip-and-Pop效应具有调节作用,这为多感觉整合在产生Pip-and-Pop效应中的作用提供了证据。     

建言类型对管理者建言采纳的影响：上下级关系的间接调节作用

基于说服模型,本研究探讨了建言类型、上下级关系、管理者感知忠诚对管理者建言采纳的影响。通过两个管理者样本的实验数据,本研究发现：(1)管理者更易采纳促进性建言而非抑制性建言;(2)在上下级关系不好的情况下,建言类型对建言采纳的影响显著,在上下级关系较好的情况下,建言类型对建言采纳的影响不显著;(3)上下级关系是通过管理者感知忠诚调节建言类型对建言采纳的影响。     

Taking control of reflexive social attention

Attention is shifted reflexively to where other people are looking. It has been argued by a number of investigators that this social attention effect reflects the obligatory bottom-up activation of domain-specific modules within the inferior temporal (IT) cortex that are specialized for processing face and gaze information. However, it is also the case that top-down factors may modulate the activation of IT cells. Here we examined behaviorally whether reflexive social orienting is purely automatic or sensitive to top-down modulation. Participants were shown an ambiguous stimulus that could be perceived either as representing EYES or a CAR. In we demonstrated between groups that an automatic shift of attention, equivalent to that triggered by a schematic FACE, occurred only when the stimulus was referred to as possessing EYES. In all participants received the EYES and CAR conditions. When the stimulus was first referred to as a CAR and then as EYES, an attentional shift was only present for the EYES condition. However, when the stimulus was first referred to as possessing EYES, and then later as a CAR, attentional shifts were observed for both conditions. These data indicate that the emergence of a reflexive social attention effect is influenced by top-down mechanisms but in an asymmetrical manner. Top-down processes appear to be effective for triggering IT involvement, that is, for perceiving a stimulus as a face, which produces the social attention effect. But top-down mechanisms are ineffective once IT involvement has been triggered. That is, once a stimulus has been seen as having eyes, it continues to be seen that way, and accordingly, the social attention effect persists.     

All Finitely Axiomatizable Tense Logics of Linear Time Flows Are CoNP-complete

We prove that all finitely axiomatizable tense logics with temporal operators for ‘always in the future’ and ‘always in the past’ and determined by linear fows time are coNP-complete. It follows, for example, that all tense logics containing a density axiom of the form ■ⁿ⁺¹_F p → ⁿ_F p, for some n ≥ 0, are coNP-complete. Additionally, we prove coNP-completeness of all ∩-irreducible tense logics. As these classes of tense logics contain many Kripke incomplete bimodal logics, we obtain many natural examples of Kripke incomplete normal bimodal logics which are nevertheless coNP-complete.     

汉字字组时间顺序的内隐记忆研究

采用再认与偏好测验的内隐记忆方法,以文字相同而字序不同的三类汉字字组为刺激材料,对汉字字组进行启动效应的实验研究,探讨汉字字组内隐的时间顺序表征存在的可能性及其加工特点。结果表明：汉字字组中字与字之间存在内隐的时间顺序表征,这种内隐的时间顺序表征是对刺激项目知觉特征中时间维度的一种反映,受知觉表征系统支配,具有自动加工和提取的特点。
