Hick's Law in a Stochastic Race Model with Speed-Accuracy Tradeoff

We present an analytic solution for a race model of n stochastic accumulators for multiple choice reaction time. We show that to maintain a constant level of accuracy, the response criterion needs to be increased approximately logarithmically with n, to compensate for the increase with n in the likelihood that an incorrect alternative will be most active after any fixed amount of time accumulating information. Assuming that participants monitor and maintain a constant level of performance can then explain the logarithmic dependency of the response latency on n as specified by Hick's law. Moreover, we show that for short time intervals, the Shannon information that observers extract from a stimulus, is predicted to increase linearly with processing time.     

Invidious Comparisons: Imagining a Psychology of Race and Gender Beyond Differences

Within psychology there is a longstanding debate concerning whether large, fundamental differences between races and genders exist. Much of this research involves comparisons that are invidious (offensively discriminating) and supports a political ideology in which members of different groups are held to be fundamentally different, alien, and therefore destined to different spheres. In this paper, specific factors are identified that make research on group differences more likely to produce distorted and partial findings. In addition, studies are cited whose methodological strategies offer insight into the processes that create and maintain group differences. Such research may illuminate not only the differences between groups, but also the very meaning of group categories. The process of scholarly peer review should become sensitive to the features that make comparisons invidious, so as to incorporate them into the criteria used to evaluate research.     

东西方面孔异族效应机理的电生理学证据

采取事件相关电位方法研究东西方面孔记忆编码的差异（DM效应）,从而阐明异族效应的神经机制。14名被试学习和再认东西方面孔照片的实验结果表明,无论记住与否,西方面孔产生的早期成分（潜伏期70~220ms）在头皮额部有一个比东方面孔更为正向的变化,表明在此阶段更多的资源分配于异族面孔,支持异族效应产生的特征选择假说。无论东方面孔还是西方面孔,记住与未记住相比较,则在额部和顶部产生潜伏期在晚期正成分（LPC）范围的正走向变化,但西方面孔在240~320ms潜伏期范围内,DM效应较小。另外,东方面孔在枕部诱发出一个明显的负波N260,而西方面孔产生的N260很小甚至没有,反映了大脑对不同种族面孔的编码机制有所不同,因而可能被称为“种族特异波”     

Dissociating automatic associations: Comparing two implicit measurements of race bias

Weak correspondence across different implicit bias tasks may arise from the contribution of unique forms of automatic and controlled processes to response behavior. Here, we examined the correspondence between estimates of automatic and controlled processing derived from two sequential priming tasks with identical structure and timing designed to separately measure stereotypic (Weapons Identification Task; WIT) and evaluative (Affective Priming Task; APT) associations. Across two studies using predominantly White samples, three consistent patterns emerged in the data: (a) stereotypic bias was stronger for Black targets, whereas evaluative bias was stronger for White targets; (b) overall response accuracy bias correlated modestly across the two tasks; and (c) multinomial processing tree estimates of controlled processing corresponded much more strongly than estimates of automatic processing. These findings support models positing distinct learning and memory systems for different forms of race bias, and suggest that these differing forms contribute to estimates of automatic associations.     

Healing and reconciliation

The Christian Church is called to the ministry of reconciliation. Despite the pain and struggle of fractured communities today, there are also stories of hope lived and told by persons who are the recipients of the ministry of local congregations and church-sponsored social service agencies. Reconciliation leads to hope, and hope leads to reconciliation.     

“Can we all get along:”1 American political divisiveness in the 21st Century

The current American political divisiveness follows prior divisive periods and is not unique. The simultaneous developments of a culture war and a partisan realignment helped to create division. Disagreement over the proper role of government completed the division. Race is a significant dividing social and political issue in America. For Reinhold Niebuhr, “Democracy is a method of finding proximate solutions to insoluble problems.” Finding agreement over policing policy may be possible, but principled political compromise over underlying issues contributing to racial inequities is likely to be harder.     

Diversifying the Social Scientific Study of Religion: The Next 70 Years

Here I argue that we need to diversify the social scientific study of religion and chart a plan for how we are already and will continue to do so. At the time of the 70th anniversary of our association, I reflect on where—as an association—we have come from and where we are going. Our origin story points to an expansive vision for what would become the Society for the Scientific Study of Religion (SSSR), but unfortunately our past has also been marked by an overrepresentation of white male leadership. It was only in 1982 that the society elected its first woman president, Mary Augusta Neal, and only in 2015 that it elected its first person of color, Fenggang Yang. Here, I discuss our hope for a more diverse future: attending to diversity in studies of religion, diversity in the groups of people who are encouraged to study religion, and efforts to translate religion research well to diverse groups of listeners. I share with you pieces of the new SSSR strategic plan, spearheaded in 2018 by Korie Edwards, the first black and woman of color President of the SSSR: particularly the pieces that are most attentive to diversity. I also highlight insights from my own scholarly story about diversity that I have learned through my work with the Religion and Public Life Program at Rice University.     

Psychological availability and work engagement: The moderating role of sex and race

This study sought to determine the relationship of sex and race as moderators of psychological availability on work engagement in various South African organisations. Participants were 1 059 employees predominantly from the corporate sector in Gauteng province (females = 61%, blacks = 36%). Cross-sectional survey data were collected from the employees using the Psychological Conditions Scale and the Utrecht Work Engagement Scale (UWES). Moderated hierarchical regression analyses tested the prediction of work engagement from psychological availability, while controlling for the sex and race of employees. Psychological availability increased the level of work engagement for both men and women, the relationship, however, was stronger for women as compared to men. White employees were less work engaged compared to other race group members. Psychological availability was higher for the black, Indian, and coloured employees compared to white employees. The results confirmed the positive relationship of psychological availability on work engagement, and that sex and race differences exist for employees in a developing country.     

Embodying the sacred and profane: how temporal empires,narratives of salvation,and the prison regime value bodies in the United States

Although analyses of the ‘sacred’ and ‘profane’ tend to remain within the discipline of religious studies, categories of sacrality and profane-ness actively shape and label all bodies in the United States. Combining theories of the sacred and profane with formulations of race, gender and sexuality, I investigate the social de/valuation of specific bodies at the turn of the twentieth and twenty-first centuries. During each period, three structural factors influence these categorisations: empires of hegemonic social time, dominant Christian narratives of salvation and the role of prison. A comparative analysis demonstrates both continuity and specificity in producing sacred and profane bodies.
