Discriminated interresponse times: role of autoshaped responses.

When discriminated interresponse-time (IRT) procedures have been used to assess preference relations among temporally extended operants, deviations from matching have been obtained. Using a yoked-control procedure, the present study found that key pecking in a discriminated IRT procedure has two sources of strength--that arising from the response-reinforcer contingency that is explicitly arranged, and that arising from a stimulus-reinforcer contingency that is a by-product of the explicitly arranged contingency. The key pecking of all lead birds, and that of 3 of the 4 birds exposed to a yoked autoshaping procedure, was controlled by the keylight that signaled the lead birds' criterion IRTs. Because stimulus control of key pecking by the keylight, whether autoshaped or discriminative, fosters deviations from matching, the discriminated IRT procedure does not provide an appropriate basis for conclusions about preference relations among IRTs.     

Perceptions of Ethical Behaviour among Business Faculty in Canada

Faculty members at Canadian business schools were surveyed regarding their ethical perceptions of behaviours related to undergraduate instruction. Fifty-five behavioural statements were listed and respondents were asked to rate the extent to which they felt each behaviour was ethical or unethical. The only item that respondents endorsed as unequivocally unethical (90% indicated it was definitely unethical) was Becoming sexually involved with an undergraduate in one of your classes. We also compared the results of our sample to those of an American sample. Overall, an interesting pattern of differences emerged between the responses obtained in Canada and the U.S. In general, the direction of the significant differences was such that Canadian professors viewed the behaviours in question as less ethical than did their American counterparts.     

A computer-based program to teach braille reading to sighted individuals

Instructors of the visually impaired need efficient braille‐training methods. This study conducted a preliminary evaluation of a computer‐based program intended to teach the relation between braille characters and English letters using a matching‐to‐sample format with 4 sighted college students. Each participant mastered matching visual depictions of the braille alphabet to their printed‐word counterparts. Further, each participant increased the number of words they read in a braille passage following this training. These gains were maintained at variable levels on a maintenance probe conducted 2 to 4 weeks after training.     

Effects of Nonverbal Behavior on Perceptions of a Female Employee's Power Bases

Abstract

The authors extended a previous examination of the effects of nonverbal behavior on perceptions of a male employee's power bases (H. Aguinis, M. M. Simonsen, & C. A. Pierce, 1998) by examining the effects of nonverbal behavior on perceptions of a female employee's power bases. U.S. undergraduates read vignettes describing a female employee engaging in 3 types of nonverbal behavior (i.e., eye contact, facial expression, body posture) and rated their perceptions of the woman's power bases (i.e., reward, coercive, legitimate, referent, expert, credibility). As predicted, (a) direct eye contact increased perceptions of coercive power, and (b) a relaxed facial expression decreased perceptions of all 6 power bases. Also as predicted, the present results differed markedly from those of Aguinis et al. (1998) regarding a male employee. The authors discuss implications for theory, future research, and the advancement of female employees.     

矛盾年龄偏见量表在中国大学生群体中的修订及信效度检验

目的:修订矛盾年龄偏见量表(the Ambivalent Ageism Scale,AAS),并在中国大学生群体中进行信、效度检验。方法:对1182名大学生施测AAS中文翻译版,探索并验证其因子结构,分析信、效度和测量等值性。其中347人还完成老化知识量表(FAQ)和容纳他人量表(AOS),用以检验AAS中文版的校标关联效度。另有74人在4周后重测AAS中文版。结果:AAS中文修订版包含认知帮助/保护、不想要的帮助和敌意年龄偏见三因子,总量表和各维度的Cronbach's α系数依次为0.83、0.80、0.85、0.76,重测信度依次为0.78、0.62、0.78、0.71。AAS中文修订版及各维度与FAQ和AOS负相关(r=-0.23～-0.48,ps<0.001)。验证因素分析表明AAS中文修订版的拟合良好(χ2/df=3.51,CFI=0.96,TLI=0.94,RMSEA=0.07,SRMR=0.05)。且该量表跨性别形态、弱等值、部分强等值和部分严格测量等值成立。结论:修订后的矛盾年龄偏见量表(AAS)中文版的信、效度良好,具备跨性别的测量部分等值性,可以用于测量中国大学生的矛盾年龄偏见。     

我国贫困大学生心理健康变迁的横断历史研究:1998~2015

为探讨自1999年高校国家助学贷款政策出台以来,我国贫困大学生心理健康状况的变迁,本研究对106篇1998至2015年间采用SCL-90量表的研究进行了横断历史元分析,考察了贫困大学生心理健康状况随年代的变化趋势。结果表明：（1）SCL-90量表中9个因子的分数均值均与年代呈负相关,年代对各因子变异的解释在4%至16%之间;1998年到2015年这18年来,各因子均值平均下降范围（效果量d）在0.24至0.55个标准差之间,其中强迫、抑郁和精神病3个因子均值变化尤为明显。这表明贫困大学生整体心理健康的状况在缓慢提升。（2）与中部地区相比,东部和西部地区贫困大学生心理健康水平18年来提高更明显。（3）虽然不同性别贫困大学生各因子历年变化差异并不明显,但女生抑郁和精神病两方面改善略快。此外,普通元分析结果表明总体上贫困男大学生比女大学生心理健康状况要好。     

贫困大学生元刻板印象威胁对群际关系的影响:群际焦虑的中介和自尊的调节作用

元刻板印象威胁是指消极元刻板印象所导致的群体成员的一种社会心理困境和认知不平衡状态,会诱发压力和害怕体验,进而损害其行为表现。基于群际焦虑模型,本研究拟考查元刻板印象、群际焦虑、自尊等因素对群际关系的影响,具体为贫困大学生消极元刻板印象对群际关系的影响及群际焦虑的中介作用、自尊的调节作用。研究以江苏省徐州市某高校的158名贫困大学生为被试,通过操控指导语的方式将其随机分为威胁组（消极元刻板印象激活组）和无威胁组（元刻板印象未激活组）。结果如下：（1）威胁组被试的群际焦虑水平显著高于无威胁组,群际关系水平显著低于无威胁组;（2）群际焦虑在元刻板印象威胁与群际关系间起中介作用,自尊在前半路径（元刻板印象和群际焦虑间）和后半路径（群际焦虑与群际关系间）均起调节作用。结论：激活贫困大学生消极元刻板印象会对群际关系产生威胁效应。     

大学生情绪智力与心理健康的关系:社会支持的中介作用和手机依赖的调节作用

以621名大学生为被试，采用情绪智力量表、心理症状自评量表、青少年社会支持评定量表、手机依赖指数量表为研究工具，探讨情绪智力与心理健康之间的关系，并在此基础上构建一个有调节的中介模型，探究社会支持的中介作用以及手机依赖在这一中介过程中的调节作用。结果发现：（1）情绪智力对心理健康的影响显著，社会支持在其中起部分中介作用，即情绪智力既可以直接影响心理健康，还可以通过社会支持的中介作用间接影响心理健康；（2）手机依赖调节了情绪智力通过社会支持影响大学生心理健康的中介过程的后半路径，相对于低手机依赖的大学生，高手机依赖大学生的社会支持对心理健康的影响更为显著。关注大学生心理健康，不仅要重视个体因素、生态环境因素的单独影响，更要重视这些因素的联合作用。     

Conversation with 2016 American Academy of Religion Excellence in Teaching Award Winner Joanne Maguire Robinson

This conversation between the editors of Teaching Theology and Religion and Joanne Maguire Robinson continues an occasional series of interviews that has previously featured Jonathan Z. Smith, Stephen Prothero, Mary Pierce Brosmer, and Mary Elizabeth Mullino Moore. The exchange takes as its point of departure the teaching statement that Professor Robinson produced in support of her candidacy for the American Academy of Religion's Excellence in Teaching Award. Issues addressed include the impact of institutional context on one's teaching, teaching the humanities in universities that are ever more focused on job training, making the transition from a graduate program focused on research to teaching undergraduates who are unlikely to take even a second course in the study of religion, and ways in which women are challenged to navigate multiple responsibilities while striving to make their way in a male‐dominated academy.
