Tightness shifts in the U.S. and China: Implications of tightening or loosening norms during the coronavirus pandemic

Emergent research identifies cultural tightness-looseness as an important factor for understanding cross-national outcome differences during the coronavirus pandemic. Because perceived tightness-looseness can be measured as an individual-level difference rather than a nation-level difference, and because tightness-looseness may shift during large-scale crises, we investigated whether such shifts occurred early in the coronavirus pandemic in both China (a relatively tight nation, n = 3642) and the U.S. (a relatively loose nation, n = 3583) across three cohorts. Tightness increased across cohorts in China and reduced across cohorts in the U.S. These changes transmitted corresponding indirect effects whereby compliance and institutional trust (scientific and government) about the pandemic were increased in China across cohorts, but decreased in the U.S. across cohorts. These patterns extend advice that national governments can increase compliance and trust via “tightening” by cautioning against norm-setters signaling the reverse (that norms about compliance are loose) given the outcomes observed in the U.S. samples.     

口语句子的韵律边界：窥探言语理解的秘窗

韵律边界加工与言语理解紧密相关, 最近十几年来逐渐成为心理学和语言学的研究焦点。韵律系统包含若干由小到大的韵律单位, 不同单位的韵律成分其边界强度不同, 表现在音高、延宕和停顿三个声学线索上的参数也不同。句子的听力理解过程中, 听话人运用声学线索感知权重策略对韵律边界的声学线索进行加工。从神经层面上来看, 对于韵律边界的加工, 大脑显示出独立且特异性的神经机制。韵律边界的加工能力在婴儿出生后随年龄的增长而发展, 到了老年阶段则逐渐退化, 而且似乎能够对二语迁移。未来, 需要扩大对韵律边界声学表现的考查范围, 进一步明确韵律边界的加工过程, 进一步厘清韵律边界加工和句法加工之间的关系, 进一步关注二语者韵律边界加工能力的发展。     

The effects of self-brand connections on responses to brand failure: A new look at the consumer–brand relationship

We argue that consumers with high self-brand connections (SBC) respond to negative brand information as they do to personal failure — they experience a threat to their positive self-view. After viewing negative brand information, high (vs. low) SBC consumers reported lower state self-esteem. Consumers with high SBC also maintained favorable brand evaluations despite negative brand information. However, when they completed an unrelated self-affirmation task, they lowered their brand evaluations the same as low SBC consumers. This finding suggests that high SBC consumers' reluctance to lower brand evaluation might be driven by a motivation to protect the self rather than the brand.

On the limitations of fixed‐step‐size adaptive methods with response confidence

The family of (non‐parametric, fixed‐step‐size) adaptive methods, also known as ‘up–down’ or ‘staircase’ methods, has been used extensively in psychophysical studies for threshold estimation. Extensions of adaptive methods to non‐binary responses have also been proposed. An example is the three‐category weighted up–down (WUD) method (Kaernbach, 2001) and its four‐category extension (Klein, 2001). Such an extension, however, is somewhat restricted, and in this paper we discuss its limitations. To facilitate the discussion, we characterize the extension of WUD by an algorithm that incorporates response confidence into a family of adaptive methods. This algorithm can also be applied to two other adaptive methods, namely Derman's up–down method and the biased‐coin design, which are suitable for estimating any threshold quantiles. We then discuss via simulations of the above three methods the limitations of the algorithm. To illustrate, we conduct a small scale of experiment using the extended WUD under different response confidence formats to evaluate the consistency of threshold estimation.     

工作家庭间跨界增益:逻辑主线与模型

已有工作家庭界面研究主要立足于冲突视角,近年来部分研究开始从积极视角揭示工作家庭关系的本质。工作家庭增益强调角色资源的跨界渗溢有助提升个体另一角色表现和生活品质的程度。工作家庭资源会增强个体心理资源,进而影响体验工作家庭间的跨界增益,资源的累积循环与工作家庭增益互为持续保障,跨界增益的程度受到工作家庭边界特征的调节影响。论证和提出了"角色资源累积-个体心理因素改变-跨界增益-角色评价与投入"的逻辑主线,以此构建工作家庭间角色资源跨界增益模型。     

Hydrogen-induced cold cracking in heat-affected zone of low-carbon high-strength steel

The Y-groove cracking test by submerged arc welding was employed to study the susceptibility of a low-carbon high-strength steel to hydrogen-induced cold cracking (HICC). The morphology of hydrogen cracks was observed using an electron probe microscope. The results showed that the heat-affected zone (HAZ) has a higher susceptibility to HICC than the weld metal and that increasing heat input can improve the HICC resistance of the weldment. The intergranular microcracking is the main HICC mode at the lowest heat input condition, accompanied with some transgranular microcracks attached to complex inclusions. In combination with phase transformation behaviour in sub-zones, the effect of the phase transformation sequence is proposed to try to illustrate the fact that the fine-grained HAZ has higher probability of hydrogen cracking than the coarse-grained HAZ owing to the occurrence of hydrogen enrichment in the fine-grained HAZ after the transformation.

Children's Understanding of the Instrumental Value of Products and Brands

Gelman and Echelbarger (2019—this issue) provide a valuable discussion about children's understanding of the inferred or nonobvious features of objects, which has implications for how children value products. We further this conversation by examining how children value products and brands as a means for meeting important goals, which we refer to as instrumental valuation. Specifically, we examine developmental trends in instrumental valuation for three goals—self‐concept development, self‐presentation, and happiness. Across these areas, we find that children place greater value on products and brands for meeting these goals as they grow older, particularly during late childhood and early adolescence. We conclude with a discussion of how age differences in instrumental valuation add to the general conversation about how children of different ages value objects.
