亲社会名声与亲社会行为

亲社会名声是行动者获得的亲社会特质声誉, 它有益于行动者的社会适应。行动者首先通过亲社会行为建立亲社会名声, 亲社会名声又通过间接互惠和同伴选择过程对行动者产生外在激励作用, 通过自我概念对行动者产生内在激励作用, 进而促进其亲社会行为。行动者的贫富水平、亲社会行为的公开性、自我获益和宣传方式影响其亲社会名声的获得。未来研究应关注亲社会行为与亲社会名声之间的相互促进过程, 探索行动者亲社会行为的代价与获益如何交互影响其亲社会名声; 行动者的社会阶层如何通过对人们预期的影响而调节行动者的亲社会名声; 亲社会名声促进亲社会行为的内在机制与边界条件。     

“Noxious Weed”: Persecution in the Development of Korean Christianity

The experience of persecution during the late Joseon and Japanese colonial period was not unusual for Korean Christians, who endured living as a minority faith within a hostile context. Like the pre‐Constantinian Christian communities and many Christians today who live in the global South, suspicion and persecution defined their world as openly confessing Christians, and they embraced, as part of converting to Christianity, the stark reality that their faith could incur personal harm in the form of hostility, incarceration, and even death. This article explores how conversion and maintaining Christian faith in a society adverse to Christianity shaped believers’ self‐understanding of the breadth of faith and acceptance of its mortal implications. Focusing on the Catholic and Protestant experience in Korea, Christian believers rigorously tested the country's attitudes against Christianity. In so doing, their experience provokes a critical reflection on the profoundness of the missionary mandate and illuminates the complexity with which their faith is forged as they must confront the brutal reality that they may be, at the very least, arrested. For many Korean Christians during Joseon Dynasty and the Japanese colonial period (1910–1945), conversion to Christianity was part of the process that transformed for believers a religious identity that was understood to be potentially detrimental to their relationship with the state.     

Tests of Simple Slopes in Multiple Regression Models with an Interaction: Comparison of Four Approaches

In multiple regression researchers often follow up significant tests of the interaction between continuous predictors X and Z with tests of the simple slope of Y on X at different sample-estimated values of the moderator Z (e.g., ±1 SD from the mean of Z). We show analytically that when X and Z are randomly sampled from the population, the variance expression of the simple slope at sample-estimated values of Z differs from the traditional variance expression obtained when the values of X and Z are fixed. A simulation study using randomly sampled predictors compared four approaches: (a) the Aiken and West (1991 Aiken, L. S., &; West, S. G. (1991). Multiple regression: Testing and interpreting interactions. Newbury Park, CA: Sage.[Crossref] , [Google Scholar]) test of simple slopes at fixed population values of Z, (b) the Aiken and West test at sample-estimated values of Z, (c) a 95% percentile bootstrap confidence interval approach, and (d) a fully Bayesian approach with diffuse priors. The results showed that approach (b) led to inflated Type 1 error rates and 95% confidence intervals with inadequate coverage rates, whereas other approaches maintained acceptable Type 1 error rates and adequate coverage of confidence intervals. Approach (c) had asymmetric rejection rates at small sample sizes. We used an empirical data set to illustrate these approaches.     

Characterizing Human Expertise Using Computational Metrics of Feature Diagnosticity in a Pattern Matching Task

Forensic evidence often involves an evaluation of whether two impressions were made by the same source, such as whether a fingerprint from a crime scene has detail in agreement with an impression taken from a suspect. Human experts currently outperform computer‐based comparison systems, but the strength of the evidence exemplified by the observed detail in agreement must be evaluated against the possibility that some other individual may have created the crime scene impression. Therefore, the strongest evidence comes from features in agreement that are also not shared with other impressions from other individuals. We characterize the nature of human expertise by applying two extant metrics to the images used in a fingerprint recognition task and use eye gaze data from experts to both tune and validate the models. The Attention via Information Maximization (AIM) model (Bruce & Tsotsos, 2009) quantifies the rarity of regions in the fingerprints to determine diagnosticity for purposes of excluding alternative sources. The CoVar model (Karklin & Lewicki, 2009) captures relationships between low‐level features, mimicking properties of the early visual system. Both models produced classification and generalization performance in the 75%–80% range when classifying where experts tend to look. A validation study using regions identified by the AIM model as diagnostic demonstrates that human experts perform better when given regions of high diagnosticity. The computational nature of the metrics may help guard against wrongful convictions, as well as provide a quantitative measure of the strength of evidence in casework.     

知觉负载对负性分心面孔的知觉加工和记忆的影响

本研究采用视觉搜索和意外再认记忆任务,结合事件相关电位技术,考察知觉负载对负性分心面孔的知觉加工和记忆的影响。在视觉搜索任务中,行为上恐惧分心面孔在高负载下干扰任务。ERP结果上,恐惧比中性分心面孔诱发更大的N170和N250;在低负载下恐惧比中性分心面孔诱发更大的N700,在高负载下没有差异。在意外再认记忆中,个体对低负载下的恐惧分心面孔表现出记忆。这些结果说明负性分心物在早期是自动化加工;晚期加工受知觉负载的调节,负载越低对负性分心物的过滤越少,存在对负性分心物的记忆偏向。

Association of Dopamine D2 Receptor Gene with Creative Ideation

Although several studies suggest that dopamine D2 receptor (DRD2) gene may contribute to creativity, the relationship between DRD2 and creativity still needs to be further validated. To further test the relevance of DRD2 and creativity, this study explored the association between DRD2 and creative ideation in 483 unrelated healthy Chinese undergraduate students. A total of 15 single nucleotide polymorphisms (SNPs) covering the DRD2 were genotyped, and creative ideation was assessed by the Runco Ideational Behavior Scale (RIBS). Single SNP analysis showed that 2 SNPs (rs4648317 and rs4938019) were nominally associated with fluency, 4 SNPs (rs4648317, rs4938019, rs4648319, and rs1800497) were nominally associated with flexibility, and 1 SNP (rs4648317) was nominally associated with originality. Haplotype analysis showed several haplotypes were nominally associated with various creative ideation indexes. However, none of these nominal associations survived correction for multiple testing. Overall, this study provides suggestive evidence for the genetic impact of DRD2 on creative ideation and supports the assumption that the genotype variations in DRD2 contribute to creativity.     

Internet Use in Young Adult Males: from the Perspective of Pursuing Well-Being

This study explored notable and measurable differences between intense users and less intense internet users in college students as they pursue well-being in the context of positive psychology. A total of 1024 male students from four general universities in China, served as study participants; data were collected via Internet Addiction Test, Multidimensional Scale of Perceived Social Support, Online Social Support Scale, and Subjective Well-Being Scale. Results showed that compared to less intense internet users, intense users perceive limited real-life social support but considerable online social support. For intense users, online social support influences their subjective well-being partially through the intervening variable of self-esteem; for the less intense internet users, online social support has an insignificant predictive effect on self-esteem or well-being.     

Association between Child Abuse and Health Risk Behaviors among Chinese College Students

Little is known about the link between child abuse and health risk behaviors among Chinese college students. This cross-sectional study examined the prevalence of child abuse and its relations with individual and clusters of health risk behaviors among Chinese college students. A total of 507 students participated in this survey. The prevalence of child abuse from the highest to the lowest was emotional neglect (53.9%), physical neglect (49.0%), emotional abuse (21.8%), physical abuse (18.3%), and sexual abuse (18.1%), respectively. Males were more likely to report child abuse than females (p?<?0.01). For males, emotional abuse was associated with internet addiction [OR?=?2.28; 95%CI (1.00, 5.20)] and suicidal behavior [OR?=?12.47, 95%CI (2.61, 59.54)]; while sexual abuse was associated with internet addiction [OR?=?2.30, 95%CI (1.14, 4.66)]. For females, emotional abuse was significantly associated with increased risks for self-harm behavior [OR?=?15.03, 95%CI (3.59, 63.07)] and suicidal behavior [OR?=?5.16, 95%CI (1.63, 16.40)]. Physical abuse was related to risks for internet addiction [OR?=?2.50, 95%CI (1.03, 6.04)] significantly. Two-step cluster analysis showed that participants in clusters with more health risk behaviors reported higher scores of child abuse. These findings suggest that child abuse was associated with both individual and clustering of health risk behaviors among Chinese college students.     

Feature-based attention resolves depth ambiguity

Perceiving the world around us requires that we resolve ambiguity. This process is often studied in the lab using ambiguous figures whose structures can be interpreted in multiple ways. One class of figures contains ambiguity in its depth relations, such that either of two surfaces could be seen as being the “front” of an object. Previous research suggests that selectively attending to a given location on such objects can bias the perception of that region as the front. This study asks whether selectively attending to a distributed feature can also bias that region toward the front. Participants viewed a structure-from-motion display of a rotating cylinder that could be perceived as rotating clockwise or counterclockwise (as imagined viewing from the top), depending on whether a set of red or green moving dots were seen as being in the front. A secondary task encouraged observers to globally attend to either red or green. Results from both Experiment 1 and 2 showed that the dots on the cylinder that shared the attended feature, and its corresponding surface, were more likely to be seen as being in the front, as measured by participants’ clockwise versus counterclockwise percept reports. Feature-based attention, like location-based attention, is capable of biasing competition among potential interpretations of figures with ambiguous structure in depth.
