FIELD REPLICATION OF CLASSWIDE PEER TUTORING

We conducted a large-scale field replication study of classwide peer tutoring applied to spelling instruction (Greenwood, Delquadri, & Hall, 1984). Two hundred and eleven inner-city students in four schools participated during their first- and second-grade school years. The effects of classwide peer tutoring were compared to teacher instructional procedures and pretest probes using a group replication design (Barlow, Hayes, & Nelson, 1984). Analysis of group and individual results indicated that (a) both teacher instructional procedures and classwide peer tutoring were effective in increasing spelling performance above pretest levels, (b) peer tutoring produced statistically greater gains relative to the teachers' procedures for both low and high student groups formed on pretest levels, (c) these outcomes were representative of groups, classes, individuals, and years during the project, and (d) participant satisfaction with the program was generally high. A separate analysis of the social importance of treatment outcome revealed differential findings for low and high groups related to pretest levels. Implications of these findings are discussed.     

Learning phonology with substantive bias: an experimental and computational study of velar palatalization

There is an active debate within the field of phonology concerning the cognitive status of substantive phonetic factors such as ease of articulation and perceptual distinctiveness. A new framework is proposed in which substance acts as a bias, or prior, on phonological learning. Two experiments tested this framework with a method in which participants are first provided highly impoverished evidence of a new phonological pattern, and then tested on how they extend this pattern to novel contexts and novel sounds. Participants were found to generalize velar palatalization (e.g., the change from [k] as in keep to [t⌢∫S] as in cheap) in a way that accords with linguistic typology, and that is predicted by a cognitive bias in favor of changes that relate perceptually similar sounds. Velar palatalization was extended from the mid front vowel context (i.e., before [e] as in cape) to the high front vowel context (i.e., before [i] as in keep), but not vice versa. The key explanatory notion of perceptual similarity is quantified with a psychological model of categorization, and the substantively biased framework is formalized as a conditional random field. Implications of these results for the debate on substance, theories of phonological generalization, and the formalization of similarity are discussed.     

Crossfostering in mice selectively bred for high and low levels of open-field thigmotaxis

The main purpose of this research was to investigate whether the difference in open-field (OF) thigmotaxis between mice selectively bred for high and low levels of wall-seeking behavior originated from genetic or acquired sources. Unfostered, infostered, and crossfostered mice were compared in two experiments in which the effects of strain, sex, and fostering on ambulation, defecation, exploration, grooming, latency to move, radial latency, rearing, thigmotaxis, and urination were studied. These experiments revealed that OF thigmotaxis was unaffected by the foster condition and thus genetically determined. The selected strains of mice also diverged repeatedly with regard to exploration and rearing. The findings are in line with the previously described existence of an inverse relationship between emotionality and exploration.     

Revisiting Religious Ethics as Field and Discipline

Returning to John P. Reeder's 1978 essay on “Religious Ethics as a Field and Discipline,” this essay explores debates surrounding the original intentions for the Journal of Religious Ethics (JRE) and for the field of religious ethics, as these have played out over the decades among an influential group of scholars involved with the JRE since its inception: Arthur Dyck, Ronald Green, Stanley Hauerwas, and Jeffrey Stout. While the JRE and its founding mission are in need of ongoing critique and transformation, we might well still affirm the journal's ongoing importance as a site for the negotiation of a commons, the identification of possibilities for shared life, imagined beyond exclusion and domination.     

心理脱离对工作投入的影响：促进还是抑制?

心理脱离是指非工作时间内个体在时空和心理两个层面均从工作中脱离出来, 不被工作相关问题所干扰, 并停止对工作的思考。主流研究认为心理脱离对工作投入具有正向影响, 但也有研究发现两者为负向关系。不同研究结果的矛盾是由于未区分心理脱离状态和心理脱离行为、下班时间和工作间歇心理脱离, 或是由于心理脱离程度差异造成, 或是两者间存在方向相反的作用机制, 或受其他变量的调节?目前的研究尚未给出一个整合的解释。因此, 本研究提出应区分心理脱离行为和心理脱离状态, 先综合采用质性与定量分析检验各自的内涵, 在此基础上依据工作要求?资源模型(Job Demands-Resources Model, 简称JD-R模型)构建一个综合模型, 采用经验取样法和情景实验法, 分别考察下班时间和工作间歇中的心理脱离行为和心理脱离状态对工作投入的影响及机制, 并考察任务紧急性和职业使命感等任务和个体特征的调节作用。预期对以往的矛盾结论给予一个整合的理论解释, 并提出相关的心理脱离管理对策, 以提升员工心理脱离状态, 从而促进其工作投入。     

A Leader Who Sees the World as I Do: Voters Prefer Candidates Whose Statements Reveal Matching Social-Psychological Attitudes

Politicians are increasingly able to communicate their values, attitudes, and concerns directly to voters. Yet little is known about which of these signals resonate with voters and why. We employ a discrete choice experiment to investigate whether and which social-psychological attitudes predict how adult British voters respond to corresponding attitudinal signals communicated by candidates in hypothetical social media posts. For all attitudes studied, covering social feelings (trust, collective nostalgia), social perceptions (nationalism, populist sentiment), and social commitments (national identification, authoritarianism, egalitarianism), we find that participants are much more likely to vote for candidates who signal proximity to their own attitudinal position and less likely for candidates who signal opposing views. The strongest effects were observed for national identification, authoritarianism, and egalitarianism, indicating the importance of commitment to a shared group and to particular principles for distributing power and resources within and between groups. We further demonstrate that social-psychological attitudes are not acting as mere proxies for participants' past votes or left–right ideology. Our results extend adaptive followership theory to incorporate preferences concerning intragroup coordination and intergroup hierarchy, while highlighting the social-psychological dynamics of political communication that may transcend the concerns of particular election cycles.     

THEOLOGICAL APPROPRIATION OF SCIENTIFIC UNDERSTANDINGS: RESPONSE TO HEFNER, WICKEN, EAVES, AND TIPLER

Abstract. Philip Hefner's focus on contingency and field as the guiding concepts in my thinking and his characterization of my theological enterprise as a Lakatosian research program are appropriate and helpful.
I welcome Jeffrey Wicken's holistic approach to the emergence of life. Theology can appropriate the language of self-organizing systems exploiting the thermodynamic flow of energy degradation for interpreting organic life as a creation of the Spirit of God.
However, I cannot sympathize with Lindon Eaves's equation of "hard science" with a reductionism which raises the double helix to the status of icon; the "meaning" of DNA derives from its place in the total phenomenon of life—not the reverse.
Frank Tipler's cosmology raises the prospect of a rapprochement between physics and theology in the area of eschatology. A Christian cosmology, however, would require at least three modifications: contingency in the history of creation; the uniqueness of Jesus' resurrection; and the relation of these to the problem of evil.     

Focal attention and the perception of pattern structure in extrafoveal vision

Several studies have shown that visual attention enhances the encoding of the positional relationships between pattern elements, i.e., the perception of pattern structure. This theoretical note discusses the possibility that the inferiority of extrafoveal vision in the perception of pattern structure results, at least partially, from less effective focal attention in the periphery. Hence, there may exist higher level differences between foveal and extrafoveal vision in information processing which cannot be explained by the spatial inhomogeneity of the retino-striate system.
