Visual field x response hand interactions and level priming in the processing of laterally presented hierarchical stimuli

Hemisphere-specific processing of laterally presented global and local stimulus levels was investigated by (a) examining interactions between the visual field of stimulus presentation and the response hand and (b) comparing intra- with inter-hemispheric effects of level priming (i.e. faster and more accurate performance when the target level repeats). Although in Experiment 1, which involved two-choice responses with left and right hands, performance costs occurred when the same hemisphere received the stimulus and controlled the response hand, further analyses suggest that these effects reflect spatial compatibility rather than intra-hemispheric interference. Consistent with the spatial compatibility interpretation, in Experiment 2 a similar visual field x response interaction was obtained with regard to left and right responses given with the same hand. Trial-to-trial level priming occurred in both experiments and was unaffected by the intra-hemispheric sequence of target levels. Implications regarding hemispheric processing mode are discussed.

Power affects basic cognition: Increased attentional inhibition and flexibility

The present article examines effects of power on basic cognition. It proposes that power bolsters the ability to attend to information selectively; enhancing the processing of information that is related to accessible constructs in detriment of peripheral, less accessible information. In contrast, powerlessness increases attunement to peripheral information, inducing greater distractibility and less attentional flexibility. Experiment 1 focuses on attention to an object and its context. Experiment 2 examines attentional focus and readiness to act. Experiment 3 examines attention to global vs. local aspects of a focal target. Powerful individuals, relative to powerless individuals, showed greater ability to inhibit peripheral information, and greater ability to focus attention in line with the demands of the task. Furthermore, inhibiting peripheral information facilitated action. The consequences of these findings for different domains are discussed.     

语篇理解中语境对代词理解的影响

该研究考察了语篇理解中整体语境和局部语境对代词理解的影响。向被试呈现语篇,其中包括带有语义偏向的整体语境和局部语境以及代词。要求被试判断代词的所指。结果发现,当代词和整体语境出现时,被试并不立刻判断,等局部语境也出现以后,才判断代词的先行词。这一结果支持“首先建立句子袭征,再把句子表征与语篇表征相整合”的分阶段加工观点。     

Sustained attention to local and global target features is different: Performance and tympanic membrane temperature

Vision researchers have investigated the differences between global and local feature perception. No one has, however, examined the role of global and local feature discrimination in sustained attention tasks. In this experiment participants performed a sustained attention task requiring either global or local letter target discriminations or watched the same displays without any work imperative. Reaction time to targets was slower when global feature discriminations were required than when local feature discriminations were required. Tympanic membrane temperature (TMT) was utilized in this study as an index of cerebral activation. Participants in the global letter detection condition had elevated post-task right TMT, indicative of reduced cerebral activation in the right hemisphere, in comparison to participants in the local letter detection or no-work imperative conditions. Both the performance and physiological results of this study indicate increased cognitive fatigue when global feature discriminations are required.     

Combining diversity and dispersion criteria for anticlustering: A bicriterion approach

Most partitioning methods used in psychological research seek to produce homogeneous groups (i.e., groups with low intra-group dissimilarity). However, there are also applications where the goal is to provide heterogeneous groups (i.e., groups with high intra-group dissimilarity). Examples of these anticlustering contexts include construction of stimulus sets, formation of student groups, assignment of employees to project work teams, and assembly of test forms from a bank of items. Unfortunately, most commercial software packages are not equipped to accommodate the objective criteria and constraints that commonly arise for anticlustering problems. Two important objective criteria for anticlustering based on information in a dissimilarity matrix are: a diversity measure based on within-cluster sums of dissimilarities; and a dispersion measure based on the within-cluster minimum dissimilarities. In many instances, it is possible to find a partition that provides a large improvement in one of these two criteria with little (or no) sacrifice in the other criterion. For this reason, it is of significant value to explore the trade-offs that arise between these two criteria. Accordingly, the key contribution of this paper is the formulation of a bicriterion optimization problem for anticlustering based on the diversity and dispersion criteria, along with heuristics to approximate the Pareto efficient set of partitions. A motivating example and computational study are provided within the framework of test assembly.

Attribute-value functions as global interpretations of attribute importance

In order to better understand decision maker’s perceptions of the importance of attributes, Goldstein (1990) differentiates between global and local interpretations of attribute importance. While the appreciation for the distinction is growing, research on the relationship between measures of global and local importance is inconclusive. We believe that these inconclusive findings are caused by operationalizing global attribute importance with single-point measures that implicitly assume that the global interpretation of attribute importance linearly depends on the relevant range of context-specific attribute levels. To address this, we propose to operationalize the global interpretation of attribute importance by estimating decision makers’ attribute-value functions. Two empirical studies demonstrate that the shape of attribute-value functions changes from concave to convex with global attribute importance. Furthermore, the steepness of these functions increases with global attribute importance while the diminishing sensitivity decreases. Finally, it is demonstrated that the inconclusive findings about the relationship between common, single-point measures of global and local attribute importance is driven by non-linearities in decision makers’ attribute-value functions. The results suggest great promise for future research on using decision makers’ attribute-value functions for measuring the importance of attributes.     

Memory and identity among post-Soviet Evangelical Christians–Baptists in contemporary Ukraine

Evangelical Christians–Baptists (ECBs) are a prominent denomination in contemporary Ukraine. They survived persecution by Soviet state atheism and are meeting the challenges of postcommunist freedom. They provide good ground for a case study on how religious communities preserve their collective memories and identities when times and conditions change. In this paper, based on various sources produced by churches and religious organisations, I analyse the ways in which ECBs maintain and reflect upon their collective memories and reinvent their traditions. Particularly I focus on historical narratives and commemorations. I argue that the ECBs develop their collective memories in transnational, local and personal perspectives. They are eager to see the history of their community as an inalienable part of the national history of Ukraine, but also consider themselves as both rooted in Russian culture and heirs of a European Protestant tradition. The main values in the core of their memory discourse are holiness, spirituality, suffering for faith and survival of the community in a hostile society. Celebrations of faith heroes and martyrs are especially popular among those who belong to the former underground wing of this denomination. A more recent trend is the celebration of the history of local congregations. As ECBs perceive threats to their traditional way of life from the West and the national liberalism of today, they become more fundamentalist and persistent in its preservation and protection. Ultimately, in order to defend their cultural space from ‘immoral’ influences, they have become more politically active and have contributed to conservative and anti-liberal agendas on the national level in Ukraine.     

初中流动儿童的内隐群体偏爱、社会支持及其对学校适应的影响

以群体偏爱的IAT测验为实验材料,结合社会支持和学校适应问卷,考察初中流动儿童在内隐群体偏爱、社会支持上与本地儿童之间的差异,并探讨这两种变量对流动儿童学校适应的影响.结果表明：（1）流动儿童存在内隐外群体偏爱,对自身所属群体表现出内隐的消极认同;本地儿童存在内隐内群体偏爱,对流动儿童具有内隐的消极认知;（2）流动儿童在父亲、教师以及同性朋友的社会支持上显著差于本地儿童;（3）在对流动儿童学校适应的影响上,社会支持的主效应显著,内隐群体偏爱和社会支持的交互作用显著;高内隐群体偏爱组中,高社会支持流动儿童的学校适应优于低社会支持儿童.
