Working memory capacity of biological movements predicts empathy traits

Working memory (WM) and empathy are core issues in cognitive and social science, respectively. However, no study so far has explored the relationship between these two constructs. Considering that empathy takes place based on the others’ observed experiences, which requires extracting the observed dynamic scene into WM and forming a coherent representation, we hypothesized that a sub-type of WM capacity, i.e., WM for biological movements (BM), should predict one’s empathy level. Therefore, WM capacity was measured for three distinct types of stimuli in a change detection task: BM of human beings (BM; Experiment 1), movements of rectangles (Experiment 2), and static colors (Experiment 3). The first two stimuli were dynamic and shared one WM buffer which differed from the WM buffer for colors; yet only the BM conveyed social information. We found that BM-WM capacity was positively correlated with both cognitive and emotional empathy, with no such correlations for WM capacity of movements of rectangles or of colors. Thus, the current study is the first to provide evidence linking a specific buffer of WM and empathy, and highlights the necessity for considering different WM capacities in future social and clinical research.     

Family Expressiveness Mediates the Relation Between Cumulative Family Risks and Children’s Emotion Regulation in a Chinese Sample

Family expressiveness, a reflection of a family’s emotional environment, has been identified as a critical factor that influences children’s emotion regulation, yet research on this topic is limited, especially in varying cultural contexts. The present study addresses this research gap and expands on the extant literature by examining the influence of family expressiveness on children’s emotional development in the context of cumulative risks (e.g., low annual household income, parental psychological distress, parents’ education level, marital dissatisfaction and the family’s housing situation). Our final sample included one hundred and seventy-eight school-aged children (84 boys and 94 girls) and their biological parents. Results showed that higher scores on the familial risk index were related to increased emotion dysregulation and decreased adaptive emotion regulation, through the mediated effects of positive family expressiveness. Negative expressiveness, however, did not mediate the aforementioned links. Reasons for the different findings regarding positive expressiveness and negative expressiveness were discussed. These findings highlight the importance of cumulative risk on children’s emotional development in the Chinese cultural context and offer potential avenues to promote adaptive emotional development in the context of cumulative risks.     

论《淮南子》的墨子观

《淮南子》对墨子持有复杂的政治认识与态度,这在秦汉思想史上具有一定的代表性。从黄老道家的根本立场出发,“批墨”是《淮南子》政治思想的基本主张,但与此同时,《淮南子》也内在地显示出“尊墨”的政治情怀,进而试图对墨子政治思想有所借鉴和汲取,达到“融墨”之理论目的。对待墨子及其政治思想的历史态度,既凸显出《淮南子》立足黄老,融通诸子的博大精神,也彰显出墨子在秦汉政治思想发展中独特的历史影响。     

当前大学生基督教组织的发展与应对——以华东Z省H市“P教会”为例

通过运用参与观察法和个案访谈法在H市开展关于大学生基督教组织发展情况的调研,发现大学生基督教组织的组织化程度在逐步提高,有组织的传教活动频繁,传教意愿强烈,社会联系广泛,善于结合大学生特点开展宗教活动。大学生基督教组织的活跃对高校校园管理和人才培养工作造成一定干扰,构成社会稳定的潜在隐患。因此,高校及主管部门需要创新社会治理方法,构建多方联动机制,直面大学生信教问题,通过多种渠道协同加强高校思想政治工作,积极应对大学生基督教组织的不断发展。

Overestimation and contraction biases of depth information stored in working memory depend on spatial configuration

Depth perception is essential for effective interaction with the environment. Although the accuracy of depth perception has been studied extensively, it is unclear how accurate the depth information is stored in working memory. In this study, we investigated the accuracy and systematic biases of depth representation by a delayed estimation task. The memory array consisted of items presented at various stereoscopic depth positions, and the participants were instructed to estimate the depth position of one target item after a retention interval. We examined the effect of spatial configuration by comparing the memory performance in the whole-display condition where non-target memory items were present during retrieval with that in the single-display condition where non-target memory items were absent. In the single-display condition, we found an overestimation bias that the depth estimates were farther than the corresponding depth positions defined by disparity, and a contraction bias that the stored depth positions near the observer were overestimated and those far from the observer were underestimated. The magnitude of these biases increased with the number of to-be-stored items. However, in the whole-display condition, the overestimation bias was corrected and the contraction bias did not increase with the number of to-be-stored items. Our findings suggested that the number of to-be-stored items could affect the accuracy of depth working memory, and its effect depended crucially on whether the information of spatial configuration of memory display was available at the retrieval stage.     

Hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance

Hemispheric predominance has been well documented in the visual perception of alphabetic words. However, the hemispheric processing of lexical information in Chinese character recognition and its relationship to reading performance are far from clear. In the divided visual field paradigm, participants were required to judge the orthography, phonology, or semantics of Chinese characters, which were presented randomly in the left or right visual field. The results showed a right visual field/left hemispheric superiority in the phonological judgment task, but no hemispheric advantage in the orthographic or semantic task was found. In addition, reaction times in the right visual field for phonological and semantic tasks were significantly correlated with the reading test score. These results suggest that both hemispheres involved in the orthographic and semantic processing of Chinese characters, and that the left lateralized phonological processing is important for Chinese fluent reading.     

Credal pragmatism

According to doxastic pragmatism, certain perceived practical factors, such as high stakes and urgency, have systematic effects on normal subjects’ outright beliefs. Upholders of doxastic pragmatism have so far endorsed a particular version of this view, which we may call threshold pragmatism. This view holds that the sensitivity of belief to the relevant practical factors is due to a corresponding sensitivity of the threshold on the degree of credence necessary for outright belief. According to an alternative but yet unrecognised version of doxastic pragmatism, practical factors affect credence rather than the threshold on credence. Let’s call this alternative view credal pragmatism. In this paper, I argue that credal pragmatism is more plausible than threshold pragmatism. I show that the former view better accommodates a cluster of intuitive and empirical data. I conclude by considering the issue of whether our doxastic attitudes’ sensitivity to practical factors can be considered rational, and if yes, in what sense.

     

Reverse evolution in nanoscale Cu-rich precipitates of an aged Fe–Cu alloy under electropulsing

Nanoscale Cu-rich precipitates (CRPs) are one of the most important microstructural nano-features responsible for embrittlement and hardening of reactor pressure vessels (RPVs), which threaten the safe operation of nuclear power plants (NPPs) and hinder the lifetime extension of nuclear reactors. A thermally aged Fe-1.1 wt.%Cu alloy, which is used to simulate embrittlement of the irradiated RPV steels, was treated by electropulsing with various parameters. The effect of electropulsing on nanoscale CRPs was investigated by using transmission electron microscopy (TEM). Compared to the traditional heat treatment, the electropulsing treatment (EPT) can accelerate the dissolution of CRPs in an aged Fe-Cu alloy on account of the higher atomic drift flux and the additional Gibbs free energy induced by electropulsing. More importantly, EPT is likely to be a new way of eliminating irradiation-induced Cu-rich precipitates.     

环境条件和兴趣对大学生妥协决策的影响

研究旨在考察个体在选择职业时是否会为了更好的环境条件(组织、城市)而降低对兴趣的要求。对63名大学生被试开展了两个实验,采用在环境条件和兴趣水平上有不同程度差异的职位配对来模拟两难决策。结果发现:(1)对不同组织声望和兴趣水平的职位的选择无性别差异;(2)组织声望差距、组织声望差距与兴趣差距的交互作用能显著预测职位的选择;(3)对不同城市级别和兴趣水平的职位的选择有性别差异,男生比女生更少放弃兴趣;(4)兴趣差距、城市级别差距与兴趣差距的交互作用能预测男生的选择,只有兴趣差距能预测女生的选择。结论:个体会为了更好的环境而或多或少在兴趣方面妥协。
