宽恕干预对降低农村留守儿童拒绝敏感性的作用

为探讨宽恕干预对降低农村留守儿童拒绝敏感性的作用,本研究将18名高拒绝敏感性农村留守儿童随机分配到实验组和控制组,其中实验组接受为期六周的团体宽恕干预,控制组不接受任何干预。结果显示:(1)留守儿童的拒绝敏感性水平与宽恕水平之间存在显著负相关。(2)在前测数据中,实验组和控制组之间不存在显著差异;在后测和追踪数据中,实验组儿童的拒绝敏感性水平显著低于控制组。(3)在干预之后,实验组留守儿童的拒绝敏感性水平显著下降,并且维持在较低水平,而控制组留守儿童的拒绝敏感性水平始终处于较高水平。该结果在一定程度上证明宽恕干预对降低农村留守儿童的拒绝敏感性水平是有效的,并且其效果稳定。     

经颅直流电刺激右侧颞顶联合区对道德意图加工的影响*

对行为意图的理解是人类进行道德判断的重要依据,大量研究表明,右侧颞顶联合区是意图加工的关键脑区。为考察该脑区在道德判断中的重要作用,采用经颅直流电刺激技术阳极刺激右侧颞顶联合区,探讨促进该脑区的活动对被试在道德判断中意图及相关信息加工的影响。结果发现与假刺激条件相比,阳极刺激后道德判断反应时显著延长,在伤人未遂和意外伤人条件下差异显著,证明促进右侧颞顶联合区的激活能影响道德判断中的意图加工,尤其在意图与结果产生冲突的条件下效应更加显著。

Using the Depression Anxiety Stress Scale 21 (DASS‐21) across cultures

The DASS‐21 is a well‐established instrument for measuring depression, anxiety, and stress with good reliability and validity reported from Hispanic American, British, and Australian adults. However, the lack of appropriate validation among Asian populations continues to pose concerns over the use of DASS‐21 in Asian samples. Cultural variation may influence the individual's experience and emotional expression. Thus, when researchers and practitioners employ Western‐based assessments with Asian populations by directly translating them without an appropriate validation, the process can be challenging. We conducted a series of rigorous statistical tests and minimized any potential confounds from the demographic information. Following factor analyses, we performed multigroup analysis across six nations to demonstrate consistency of our findings. The advantages of this revised DASS‐18 stress scale are twofold. First, it possesses fewer items, which results in a cleaner factorial structure. Second, it has a smaller interfactor correlation. With these justifications, the revised DASS‐18 stress scale is potentially more suitable for Asian populations. Nonetheless, given limitations, findings should be considered preliminary.     

Personal Relative Deprivation Boosts Materialism

Five studies investigated the relationship between personal relative deprivation and materialism. Study 1 was a cross-sectional survey that revealed a positive association between trait relative deprivation and materialism. In Studies 2a and 2b, we found that relative deprivation, as induced by unjust government policies in an imaginary scenario, increased individuals’ preferences for making more profit than others. Individuals may experience relative deprivation due to unjust treatment or other factors. Study 3 manifested that sense of relative deprivation, resulting from either being treated unjustly or not, gave rise to materialistic desires. In Study 4, we found that relative deprivation influenced materialistic aspirations, above and beyond negative outcomes. Moreover, the impact of relative deprivation could be generalized to aspirations for fame.     

Sleep facilitates consolidation of positive emotional memory in healthy older adults

ABSTRACT

Evidence has demonstrated that sleep-related memory consolidation declines in ageing. However, little is known about age-related changes to sleep-related emotional memory consolidation, especially when considering the positivity effect observed in older adults. In the present study, we sought to explore whether there is a positive emotional bias in sleep-related memory consolidation among healthy older adults. Young and older adults were randomly assigned either into a sleep or wake condition. All participants encoded positive, negative, and neutral stimuli and underwent recognition tests immediately (test 1), after a 12-hour sleep/wake interval (test 2), and 3 days after test 2 (test 3). Results showed that age-related differences of sleep beneficial effect were modulated by emotion valence. In particular, sleep selectively enhanced positive memory in older adults, while in young adults sleep beneficial effect was manifested in neutral memory. Moreover, the sleep beneficial effect can be maintained at least 3 days in both young and older adults. These findings suggest that older adults had preserved but positive bias of sleep-related memory consolidation, which could be one of the underlying mechanisms for their generally better emotional well-being in daily life. These findings highlight the dynamic interplay among sleep and emotional memory in older adults.     

公正与关怀——民生制度与实践的伦理原则

从伦理学的视角来看,民生包含三个方面的内涵:一是公民根基性的"生存",二是公民尊严性的"生活",三是公民理想性的"好的生活".基于对中国当下民生的现状及问题的全面把握,政府在民生制度和民生实践中首先应遵循刚性的公正原则,它既能够一般地解决资源供给的有限与人的欲望的无限之间的冲突,又能有效地解决当下民生中的突出问题.但公正原则的普遍性和抽象性决定了它无法惠及每一特殊个体的需求,强调具体性、关系性、情境性、理解与关爱的关怀原则可以弥补这一缺陷.因此,以刚性的"公正"与柔性的"关怀"为伦理原则的民生制度与民生实践,将最终引领全体公民过上他们所珍视的和值得过的"好的生活".     

重释“宗教”:史密斯对于宗教概念的消解

史密斯质疑宗教概念的普遍有效性,从词源学和观念史角度对宗教的含义及其变迁作了历史考察,指出它不过是西方近代文明的一个产物,并不适合解释其他文明的生活传统,主张用信仰和累积的传统两个独立的概念取而代之。依据这一概念框架来解释儒家传统会消除一些困难。     

Odor preference learning and memory modify GluA1 phosphorylation and GluA1 distribution in the neonate rat olfactory bulb: testing the AMPA receptor hypothesis in an appetitive learning model

An increase in synaptic AMPA receptors is hypothesized to mediate learning and memory. AMPA receptor increases have been reported in aversive learning models, although it is not clear if they are seen with memory maintenance. Here we examine AMPA receptor changes in a cAMP/PKA/CREB-dependent appetitive learning model: odor preference learning in the neonate rat. Rat pups were given a single pairing of peppermint and 2 mg/kg isoproterenol, which produces a 24-h, but not a 48-h, peppermint preference in the 7-d-old rat pup. GluA1 PKA-dependent phosphorylation peaked 10 min after the 10-min training trial and returned to baseline within 90 min. At 24 h, GluA1 subunits did not change overall but were significantly increased in synaptoneurosomes, consistent with increased membrane insertion. Immunohistochemistry revealed a significant increase in GluA1 subunits in olfactory bulb glomeruli, the targets of olfactory nerve axons. Glomerular increases were seen at 3 and 24 h after odor exposure in trained pups, but not in control pups. GluA1 increases were not seen as early as 10 min after training and were no longer observed 48 h after training when odor preference is no longer expressed behaviorally. Thus, the pattern of increased GluA1 membrane expression closely follows the memory timeline. Further, blocking GluA1 insertion using an interference peptide derived from the carboxyl tail of the GluA1 subunit inhibited 24 h odor preference memory providing causative support for our hypothesis. PKA-mediated GluA1 phosphorylation and later GluA1 insertion could, conjointly, provide increased AMPA function to support both short-term and long-term appetitive memory.     

A habituation account of change detection in same/different judgments

We investigated the basis of change detection in a short-term priming task. In two experiments, participants were asked to indicate whether or not a target word was the same as a previously presented cue. Data from an experiment measuring magnetoencephalography failed to find different patterns for “same” and “different” responses, consistent with the claim that both arise from a common neural source, with response magnitude defining the difference between immediate novelty versus familiarity. In a behavioral experiment, we tested and confirmed the predictions of a habituation account of these judgments by comparing conditions in which the target, the cue, or neither was primed by its presentation in the previous trial. As predicted, cue-primed trials had faster response times, and target-primed trials had slower response times relative to the neither-primed baseline. These results were obtained irrespective of response repetition and stimulus–response contingencies. The behavioral and brain activity data support the view that detection of change drives performance in these tasks and that the underlying mechanism is neuronal habituation.
