Race and jury selection: psychological perspectives on the peremptory challenge debate

The legal system is a domain of potential relevance for psychologists, whether in the capacity of expert witness or citizen juror. In this article, the authors apply a psychological framework to legal debate surrounding the impact of race on the process of jury selection. More specifically, the authors consider race and the peremptory challenge, the procedure by which attorneys may remove prospective jurors without explanation. This debate is addressed from a psychological perspective by (a) examining traditional justifications for the practice of the peremptory challenge, (b) reviewing research regarding the influence of race on social judgment, (c) considering empirical investigations that examine directly race and peremptory challenge use, and (d) assessing current jury selection procedures intended to curtail racial discrimination. These analyses converge to suggest that the discretionary nature of the peremptory challenge renders it precisely the type of judgment most likely to be biased by race. The need for additional psychological investigation of race and jury selection is emphasized, and specific avenues for such research are identified.

Muscular contribution to low-back loading and stiffness during standard and suspended push-ups

Push-up exercises are normally performed to challenge muscles that span upper extremity joints. However, it is also recognized that push-ups provide an effective abdominal muscle challenge, especially when the hands are in contact with a labile support surface. The purpose of this study was to compare trunk muscle activation levels and resultant intervertebral joint (IVJ) loading when standard and suspended push-ups were performed, and to quantify and compare the contribution of trunk muscles to IVJ rotational stiffness in both exercises. Eleven recreationally trained male volunteers performed sets of standard and suspended push-ups. Upper body kinematic, kinetic, and EMG data were collected and input into a 3D biomechanical model of the lumbar torso to quantify lumbar IVJ loading and the contributions of trunk muscles to IVJ rotational stiffness. When performing suspended push-ups, muscles of the abdominal wall and the latissimus dorsi were activated to levels that were significantly greater than those elicited when performing standard push-ups (p<.05). As a direct result of these increased activation levels, model-predicted muscle forces increased and consequently led to significantly greater mean (p=.0008) and peak (p=.0012) lumbar IVJ compressive forces when performing suspended push-ups. Also directly resulting from the increased activation levels of the abdominal muscles and the latissimus dorsi during suspended push-ups was increased muscular contribution to lumbar IVJ rotational stiffness (p<.05). In comparison to the standard version of the exercise, suspended push-ups appear to provide a superior abdominal muscle challenge. However, for individuals unable to tolerate high lumbar IVJ compressive loads, potential benefits gained by incorporating suspended push-ups into their resistance training regimen may be outweighed by the risk of overloading low-back tissues.     

Priming addition facts with semantic relations

Results from 2 relational-priming experiments suggest the existence of an automatic analogical coordination between semantic and arithmetic relations. Word pairs denoting object sets served as primes in a task that elicits "obligatory" activation of addition facts (5 + 3 activates 8; J. LeFevre, J. Bisanz, & L. Mrkonjic, 1988). Semantic relations between the priming words were either aligned or misaligned with the structure of addition (M. Bassok, V. M. Chase, & S. A. Martin, 1998). Obligatory activation of addition facts occurred when the digits were primed by categorically related words (tulips-daisies), which are aligned with addition, but did not occur when the digits were primed by unrelated words (hens-radios, Experiment 1) or by functionally related words (records-songs, Experiment 2), which are misaligned with addition. These findings lend support to the viability of automatic analogical priming (B. A. Spellman, K. J. Holyoak, & R. G. Morrison, 2001) and highlight the relevance of arithmetic applications to theoretical accounts of mental arithmetic.

论法称因明的逻辑体系

本文以汉传因明的研究成果为基础,论证法称因明的演绎逻辑体系与陈那因明的非演绎逻辑体系有根本的差别。本文以玄奘的“唯识比量”作为标尺,论述法称因明在认识论、逻辑和辩论术三方面全面改造了陈那因明。论述了法称建立因后二相的思路与陈那有根本差别,是导致体系差别的根本原因。通过分析近似于“所闻性”因的实例,指出陈那的不共不定因在法称因明中不复存在。这是法称对陈那因明作体系性变革的重要特征。从法称《滴论》和法上疏找到根据,批评百年以来流行的归纳说。本文还找到了藏传研究者误用法称因三相来解读陈那因三相的原因。简明扼要地阐明不可得因在逻辑上没有独立性。设立此因主要为方便建立论式。文章最后解释了法称因明异法式独自成立的逻辑依据。要之,本文对当今国内因明研究中的诸多重要问题作出了自己的回应。     

Personality in Non‐human Animals

Over the past decade, research on animal personality has flourished in numerous disciplines ranging from Behavioral Ecology and Developmental Psychobiology to Genetics and Comparative Psychology. The broad appeal of animal studies is that, in comparison with human studies, they afford greater experimental control, more options for measuring physiological and genetic parameters, greater opportunities for naturalistic observation, and an accelerated life course. Past research has established that personality (a) exists and can be measured in animals; (b) can be identified in a broad array of species, ranging from squid, crickets, and lizards, to trout, geese, and orangutans; and (c) shows considerable cross‐species generality for some dimensions. The wave of new studies is shedding fresh light on traditional issues in personality research (How do early experiences affect adult personality?), raising novel questions (What are the evolutionary origins of personality traits?) and addressing practical problems (Which dogs are best suited to detecting explosives?).     

不同阅读形式下拼音对儿童汉字学习和阅读动机的长期影响

本研究以176名一年级小学生为研究对象,通过为期一年的教学实验研究,探讨了在分享阅读和独立阅读条件下,拼音对儿童汉字学习和阅读动机的影响。结果发现:(1)在分享阅读条件下,学生的汉字学习效果不受阅读材料注音方式的影响;在独立阅读条件下,拼音能促进中低能力儿童的汉字学习。(2)分享阅读组儿童的阅读动机高于独立阅读组;长期阅读全文注音材料的儿童,其阅读效能感明显低于阅读无拼音材料的儿童。     

数学能力与决策的关系：个体差异的视角

即便在相同的情形中, 每个人所做的决策也有千差万别, 导致决策个体差异的因素之一就是数学能力。文章综述了算术能力、数量表征、概率推理能力以及数学认知启发式对各种决策的影响。目前这方面的研究或者采用相关范式将数学能力作为决策的外部关联因素, 或者采用成分范式确定决策过程所需要的特定数学认知成分; 观点上的主要争论在于是一般认知能力还是数学能力在预测决策表现, 以及数学能力是否总是对决策有积极作用; 此外, 双系统模型和模糊痕迹理论有望为决策的个体差异提供理论解释。今后研究应该澄清上述争论, 确定合适的研究范式和结果解释框架, 并探讨更多提高决策能力的措施。
