Hemispheric lateralization of bilaterally presented homologous visual and auditory stimuli in normal adults, normal children, and children with central auditory dysfunction

Two experiments were conducted to examine the performance of normal adults, normal children, and children diagnosed with central auditory dysfunction presumed to involve the interhemispheric pathways on a dichotic digits test in common clinical use for the diagnosis of central auditory processing disorder (CAPD) and its corresponding visual analog. Results of the first experiment revealed a significant right ear advantage (REA) for the dichotic listening task and a left-visual-field advantage (LVFA) for the corresponding visual analog in normal adults and children. In the second experiment, results revealed a significantly larger REA in the children with CAPD as compared to the normal children. Results also revealed a reversed cerebral asymmetry (RVFA) for the children with CAPD on the visual task. Significant cross-modal correlations suggest that the two tasks may reflect, at least in part, similar interhemispheric processing mechanisms in children. Findings are discussed in relation to differential diagnosis and modality-specificity of CAPD.     

Differences in Noun and Verb Processing in Lexical Decision Cannot be Attributed to Word Form and Morphological Complexity Alone

It has been suggested that the effect of word category in noun and verb processing reflects typical word class properties, which can be characterized in terms of semantic as well as syntactic and morphological features. The present study is aimed at differentiating and discussing the relative contribution of these aspects with a main focus on syntactic and morphological processing. Experiment 1 established a processing advantage for nouns in German visual lexical decision, using nouns denoting biological and man-made objects as compared to transitive and intransitive verbs. Experiment 2 showed that the noun advantage persisted even when the morphological differences between word categories were reduced by using identical suffixes in nouns and verbs. Overall results suggest that the processing differences cannot be reduced to variables such as frequency, word form, or morphological complexity. Reaction time differences between transitive and intransitive verbs strengthen the role of syntactic information. In line with previous accounts the observed effects are discussed in terms of a category-specific combination of linguistic parameters.     

如何看待腹腔镜阑尾切除术

随着微创技术的发展,腹腔镜阑尾切除术（1aparoscopic appendectomy,LA）正逐渐被广大医务工作者所接受,但现在仍然有很多人认为LA与传统开腹阑尾切除术（open appendectomy,OA）相比没有优势,而且LA价格昂贵,不适合推广。但是作为正在发展完善的新技术,很多证据表明LA与OA相比优势正在逐步增强。     

Gandhi,secularism and social capital in modern India

The partition of the Indian subcontinent in 1947 was witness to Hindu Muslim conflict at its peak. In the 1990s, ethnic conflict was used by right wing ideologues to change the fabric of secular India. Using interview data and within a social representational framework the study demonstrates the processes whereby out-groups/in-groups are formed. Further, it is argued that religious tolerance as envisaged in Gandhian philosophy, needs to be an integral part of the debate on role of religion in the public sphere.     

The Concept of Advantage in Sport

The aim of this paper is to analyse the concept of advantage in sport. Advantage is often referred to in discussions of the philosophy of sport, but only a few analyses of the term exist. Sigmund Loland has discussed advantage most comprehensibly. Nevertheless, his view does not address all of the relevant kinds of advantage. I begin with a summary of Loland's view and then show its limitations. I continue by developing his ideas further to present what I call performance advantage, a comparative relationship between numbers attributed to performances. For instance, the performance of a football team that beat its opponent 3–2 is given a numerical value. However, another kind of advantage exists, one that I label property advantage. This term refers to advantage as a comparative relationship between different properties that affect performances. For example, a runner may have more haemoglobin than his or her competitor. I then outline the relationship between the two meanings of advantage. Finally, I summarise by stating that advantage in sport is a relationship of superiority that can be divided into performance advantage and property advantage.     

No relevant spectator impact on home advantage in male and female professional volleyball – A longitudinal multilevel logistic model analysis over 25 years

Home advantage (HA) regularly occurs in volleyball (Pollard et al., 2017: men: 56.62%, women: 55.26%). Research to date has investigated primarily small samples of mostly female matches and not looked into the potential impact of spectators on HA. This archival analysis uses multilevel modelling to examine HA in professional German volleyball (men & women) over 25 seasons in all regular and play-off matches (N = 6,833). We analyze how spectators drive HA and whether this projects to the COVID-19 season 2020/21.When intercepts varied between teams (2-level model, ICC = 27%), the winning probability increased when playing at home (men: 57.01%, OR_men = 2.39, d = 0.48; women: 55.39%, OR_women = 2.19, d = 0.43), while controlling for team strength, interaction with gender, and travelling distance. More spectators had a negligible effect on the men’s and women’s chances (|d| < 0.07). Similar trends were observed for the probability of winning sets. Contrary to other team sports (e.g., soccer), there is no HA-development over the last decades.     

嗓音源判断过程中的范畴效应和通道效应

该项研究通过设计4种实验条件,旨在探讨不同嗓音词的再认和嗓音判断过程各自的特点及其相互联系。4种实验条件是由2种诵读方式和2种测试方式组合而成,2种诵读方式为同范畴同嗓音和同范畴异嗓音,2种测试方式为视觉呈现和听觉呈现。52名大学生被试随机分成4个独立的组,分别接受一种实验处理。实验结果显示：(1)同范畴同嗓音条件与同范畴异嗓音条件相比,前者项目词的嗓音源判断效果好。提示增加相同记忆源项目间语义联系将有利于记忆源的检测判断。(2)项目再认与项目嗓音判断结果不完全一致,只有在诵读方式为同范畴同嗓音测试方式为听觉呈现情境下,两者有较高的正相关。(3)在同范畴同嗓音诵读条件下,再认反映出学习和测试通道源一致性优势效应,嗓音判断没有反映出通道源一致性优势效应。

Numerical representation and cross-cut role assignments: Majority members’ responses under cooperative interaction

This research investigates why cross-cutting role assignments, compared to those that converge, may worsen the intergroup attitudes of numerical majorities. Study 1 manipulated the numerical representation of groups and role assignments in a cooperative setting. As predicted, when the cross-cut role condition included the reintroduction of the numerical imbalance, the intergroup attitudes of majorities were more favorable than when the cross-cut condition did not reintroduce this discrepancy. Also, Study 1 showed that the intergroup attitudes of the majority were more positive when roles converged. Study 2 compared a convergent condition to one with converging roles that also reduced the salience of the majority’s numerical advantage. The results for this convergent-reduced-salience condition mimicked that of the cross-cut condition, revealing less positive majority attitudes. In both studies, results suggest that the processes of ingroup identification and relative ingroup homogeneity may mediate the effect of role assignments on ingroup bias. The findings are discussed in terms of the implications for cooperative interventions designed to improve intergroup attitudes.     

第二语言水平对双语者语言抑制能力的影响——来自英语–汉语单通道双语者和英语–美国手语双通道双语者的证据

采用同形异义词干扰任务考察第二语言水平对英语–汉语单通道双语者和英语–美国手语双通道双语者语言抑制能力的影响。结果发现:(1)高水平英语–汉语单通道双语者的语言抑制能力较强,但低水平英语–汉语单通道双语者与英语单语者的语言抑制能力没有显著差异,说明少量的双语经验不足以导致双语认知优势;(2)不同水平的英语–美国手语双通道双语者的语言抑制能力差异不显著。所以如此,与英语–美国手语双通道双语者不存在口语和手语的双语表征加工竞争有关。整个研究表明,双语认知优势效应与双语者的二语水平以及通道经验有关。
