后疫情时代：复工阶段不同阶层的社会情绪及压力因素

本研究考察新冠肺炎疫情复工阶段,不同阶层社会情绪和压力因素随时间的变化规律。基于三次问卷调查（NT1 = 1073; NT1 = 983; NT3 =1078）发现：（1）民众社会情绪均表现为积极情绪高于消极情绪,而且随时间推进社会情绪持续向好;（2）低阶层者的社会情绪始终比高阶层者更消极;（3）民众感知的安全压力随时间下降,而经济压力随时间没有显著变化;（4）低阶层者感知到更大的经济压力,高阶层者感知到更大的安全压力;（5）安全压力在社会阶层与积极情绪和消极情绪之间起显著的中介作用,经济压力在社会阶层与消极情绪之间起显著的中介作用。研究揭示了不同社会阶层在复工阶段存在社会情绪和压力来源的差异,为有针对性进行积极社会心态治理提供启示。

未来工作自我清晰度对主动职业行为的影响——一个有调节的中介模型

基于主动性行为模型和生涯建构理论探讨未来工作自我清晰度对主动职业行为的影响机制。采用主动职业行为量表、未来工作自我清晰度量表、生涯适应力量表、同事支持量表对广深两地13所民营企业的195名员工进行调查分析。结果显示:(1)未来工作自我清晰度影响主动职业行为;(2)生涯适应力在其中起到部分中介作用;(3)同事支持在中介模型的前半路径起到调节作用。     

指代者对其先行词可提取性的影响

三个实验,考察了在理解含有指代法表述的句子过程中,指代者对其先行词(即所指者)的可提取性的影响及其与先述参与者可提取性上的优势之间的关系。结果表明：(1)指代者对所指者的激活有促进作用,对非所指者有一定的抑制作用,从而提高了所指者的可提取性;(2)指代者对所指者和非所指者的这种作用有一定的时间进程;(3)指代者对所指者产生作用的时间进程随指代法表述的特性而变化;(4)句子先述参与者在可提取性上的优势是一种较普遍的认知现象。它与指代法表述中所指者的易提取性现象是一种动态的关系,指代法表述或者增强先述参与者可提取性的优势,或者会消除这种优势。     

深入批判李洪志及其“法轮功”的反动思想

李洪志的“法轮功”是一种邪教,或者说是一种附佛外道。所谓附佛外道,就是歪曲篡改佛教的一些概念、观点、思想、理论的异端邪说。现就对李洪志《转法轮》书中的“末世论”、“天象说”、“业力说”、“特异功能”等反动思想,予以分析批判。     

超越两种文化：第三种文化与变革中的当代心理学

心理学内部长期存在着科学文化与人文文化的对立与决裂,这一矛盾加剧了心理学的分裂趋势。第三种文化兴起后,既不赞同非此即彼的单一文化观,也不认可两种文化间存在着不可逾越的鸿沟,而是提出了“数据、理论、阐释”三位一体的“综合科学”概念和以“磁力”主题为中心的研究模式,积极倡导人文与科学文化的宽容、批判性反驳与合作精神,从而超越了传统意义上两种文化的观念束缚,有望为当代心理学的发展提供一种新的进路。     

Bayesian analogy with relational transformations

How can humans acquire relational representations that enable analogical inference and other forms of high-level reasoning? Using comparative relations as a model domain, we explore the possibility that bottom-up learning mechanisms applied to objects coded as feature vectors can yield representations of relations sufficient to solve analogy problems. We introduce Bayesian analogy with relational transformations (BART) and apply the model to the task of learning first-order comparative relations (e.g., larger, smaller, fiercer, meeker) from a set of animal pairs. Inputs are coded by vectors of continuous-valued features, based either on human magnitude ratings, normed feature ratings (De Deyne et al., 2008), or outputs of the topics model (Griffiths, Steyvers, & Tenenbaum, 2007). Bootstrapping from empirical priors, the model is able to induce first-order relations represented as probabilistic weight distributions, even when given positive examples only. These learned representations allow classification of novel instantiations of the relations and yield a symbolic distance effect of the sort obtained with both humans and other primates. BART then transforms its learned weight distributions by importance-guided mapping, thereby placing distinct dimensions into correspondence. These transformed representations allow BART to reliably solve 4-term analogies (e.g., larger:smaller::fiercer:meeker), a type of reasoning that is arguably specific to humans. Our results provide a proof-of-concept that structured analogies can be solved with representations induced from unstructured feature vectors by mechanisms that operate in a largely bottom-up fashion. We discuss potential implications for algorithmic and neural models of relational thinking, as well as for the evolution of abstract thought.     

Is interpolation cognitively encapsulated? Measuring the effects of belief on Kanizsa shape discrimination and illusory contour formation

Contour interpolation is a perceptual process that fills-in missing edges on the basis of how surrounding edges (inducers) are spatiotemporally related. Cognitive encapsulation refers to the degree to which perceptual mechanisms act in isolation from beliefs, expectations, and utilities (Pylyshyn, 1999). Is interpolation encapsulated from belief? We addressed this question by having subjects discriminate briefly-presented, partially-visible fat and thin shapes, the edges of which either induced or did not induce illusory contours (relatable and non-relatable conditions, respectively). Half the trials in each condition incorporated task-irrelevant distractor lines, known to disrupt the filling-in of contours. Half of the observers were told that the visible parts of the shape belonged to a single thing (group strategy); the other half were told that the visible parts were disconnected (ungroup strategy). It was found that distractor lines strongly impaired performance in the relatable condition, but minimally in the non-relatable condition; that strategy did not alter the effects of the distractor lines for either the relatable or non-relatable stimuli; and that cognitively grouping relatable fragments improved performance whereas cognitively grouping non-relatable fragments did not. These results suggest that (1) filling-in effects during illusory contour formation cannot be easily removed via strategy; (2) filling-in effects cannot be easily manufactured from stimuli that fail to elicit interpolation; and (3) actively grouping fragments can readily improve discrimination performance, but only when those fragments form interpolated contours. Taken together, these findings indicate that discriminating filled-in shapes depends on strategy but the filling-in process itself may be encapsulated from belief.     

Using HLM to Explore the Effects of Perceptions of Learning Environments and Assessments on Students’ Test Performance

The study examines the role that perceptions or impressions of learning environments and assessments play in students’ performance on a large-scale standardized test. Hierarchical linear modeling (HLM) was used to test aspects of the Learning Errors and Formative Feedback model to determine how much variation in students’ performance was explained by students’ and school principals’ perceptions of learning environments and assessments. Results from sequential HLM testing indicated that students’ but not principals’ perceptions explained a significant, although modest, amount of the total variation in students’ test performance. These results suggest that when students perceive learning environments to be safe and valuable, and positive assessment activities to be taking place, they tend to perform better on standardized tests than when they perceive learning environments and assessment activities otherwise. These findings provide a rationale for investigating the variables that can help improve students’ perceptions in order to enhance their test performance.     

A piezoelectric gyroscope based on thickness-shear modes of an AlN bimorph with inclined c-axes

We propose a new structure for piezoelectric gyroscope application. It consists of a two-layered plate of AlN with inclined c-axes. Through a theoretical analysis, it is shown that when the plate is electrically driven into thickness-shear (TSh) vibration in one direction and is rotating about the plate normal, the rotation causes a TSh vibration in a perpendicular direction with an electrical output which can be used to measure the angular rate of the rotation. Since AlN can be made into thin film devices much smaller than conventional crystal acoustic wave devices, the proposed gyroscope can be made much smaller than existing piezoelectric gyroscopes. The structure can also work with other crystals of class 6mm such as ZnO and polarized ceramics.
