Multiple‐choice tests are frequently used in personnel selection contexts to measure knowledge and abilities. Option weighting is an alternative multiple‐choice scoring procedure that awards partial credit for incomplete knowledge reflected in applicants’ distractor choices. We investigated whether option weights should be based on expert judgment or on empirical data when trying to outperform conventional number‐right scoring in terms of reliability and validity. To obtain generalizable results, we used repeated random sub‐sampling validation and found that empirical option weighting, but not expert option weighting, increased the reliability of a knowledge test. Neither option weighting procedure improved test validity. We recommend to improve the reliability of existing ability and knowledge tests used for personnel selection by computing and publishing empirical option weights. 相似文献

We sought to predict overt aggression among college students from their intra- and interpersonal relationships self-perceptions. Respondents were 311 students (females = 69.8%; black = 65.9%, white = 16.7%; mean age = 26.38 years, SD = 9.57 years) from a large South African university. Results following multivariate inferential analysis indicated Negative, destructive interpersonal relationships; Negative, destructive self-concept; and Positive inclination towards others to predict overt aggression among the university students. By contrast, Positive interaction with self and others; and Submissiveness towards others can be used to predict overt aggression among the university students. Our hypothesis that the more constructive (higher) students’ self-concept and intrapersonal relationships, interpersonal relationships, the lower will their levels of overt aggression, physical aggression and verbal aggression become was supported. As such, the finding was that: Overt Aggression = a(Negative destructive interpersonal relationships) + b(Negative destructive self-concept) ? c(Positive inclination towards others). 相似文献

组织行为学研究的现状:意义与建议 总被引:1,自引:0,他引:1
本文对2008~2011年这4个年度发表在英文和中文组织行为学方面重要学术期刊上的研究进行总结, 旨在让国内学者了解现今组织行为学的现状和发展。我们在分析研究内容、研究方法的基础上, 就当前中国组织行为学研究提出了一些总结性的看法, 包括:研究问题很大程度上追随国际潮流, 但缺乏对本土重要问题的关注; 研究方法过多地集中于定量的问卷调查法, 但缺乏对多种不同方法的应用; 研究的分析层次过多地集中在个体层次上, 而对多层次的组织和团队管理现象关注不足。为更好地促进组织行为学科的发展, 本文建议:应该注重立足中国的组织和管理现象来挖掘研究问题; 采用多种研究方法, 特别应鼓励开展定性研究; 注重跨层次研究和研究的情境化等。本文通过介绍近年来组织行为领域的全面情况并详细分析其中的若干个例, 为如何克服以上不足提供具体的范例和方法。 相似文献

选取40名老年人和38名年轻人做被试,以同时携带“年龄-性别”信息、体现着社会多重范畴的面孔作为靶子刺激,探究年龄或性别范畴中某一范畴发生变化时,多重社会范畴的类别化加工特性以及各个子范畴的类别化加工之间的相互关系。在此基础上进一步探讨了不同年龄(老年人-青年人)和性别(男性-女性)的认知者在面对社会多重范畴时相应的类别化加工过程是否存在差异。结果发现:当年龄或者性别中的某个社会范畴发生变化时,另一社会范畴的类别化加工未能达到完全自动化加工水平。具体地,年龄类别化加工的自动化程度高于性别;老年人对于面孔中的社会范畴信息的加工速度慢于年轻人;对老年面孔中的社会范畴信息进行加工需要耗费更多的认知资源;相对于老年女性而言,认知者更加偏好年轻女性的面孔。 相似文献

Effects of serial and concurrent training on receptive identification tasks: A Systematic replication 下载免费PDF全文
The current study compared the use of serial and concurrent methods to train multiple exemplars when teaching receptive language skills, providing a systematic replication of Wunderlich, Vollmer, Donaldson, and Phillips (2014). Five preschoolers diagnosed with developmental delays or autism spectrum disorders were taught to receptively identify letters or letter sounds. Subjects learned the target stimuli slightly faster in concurrent training and a high degree of generalization was obtained following both methods of training, indicating that both the serial and concurrent methods of training are efficient and effective instructional procedures. 相似文献

Establishing derived categorical responding in children with disabilities using the PEAK‐E curriculum 下载免费PDF全文

The purpose of the study was to evaluate a procedure to generate derived categorical responding by three children with disabilities and to promote the emergence of untrained intraverbal categorical responses. In the study, three 4‐member equivalence classes including three stimuli (A, B, and C) and a category name (D) for each class were trained using a match‐to‐sample procedure. Test probes were conducted for categorical responding, including both a trained (D‐A) and two derived (D‐B, D‐C) relational responses, as well as the emergence of untrained intraverbal categorical responding (D‐A/B/C) throughout the study. Relational training was effective at promoting the emergence of categorical responding, and two of the three participants demonstrated the emergence of additional intraverbal responding without prior training. The results provide further evidence supporting the practical utility of stimulus equivalence as well as the PEAK‐E curriculum. 相似文献

A microswitch‐based program for promoting initial ambulation responses: An evaluation with two girls with multiple disabilities 下载免费PDF全文

We assessed the use of a microswitch‐based program for promoting ambulation responses by two children with multiple disabilities. The goals of the study were to: (a) evaluate the importance of the contingency between the target behavior (forward step) and the programmed consequence (preferred stimuli), (b) measure effects of the intervention on indices of happiness, and (c) assess the social validation of the procedure using 20 physiotherapists as external raters. The intervention involved the automatic delivery of preferred stimuli contingent on forward steps. Results showed that both participants improved their performance (forward steps and indices of happiness) during contingent reinforcement phases compared to baseline and noncontingent reinforcement phases. Moreover, physiotherapists rated the intervention as socially valid. 相似文献

In the social context of job engagement, the role of trust in supervisor in predicting engagement of employees has received attention in research. Very limited research, however, has investigated the mechanisms mediating this dynamic relationship. To address this important gap in knowledge, the aim of this study was to examine psychological safety and felt obligation as two psychological mechanisms mediating the effect of trust in supervisor on job engagement. Drawing from job engagement and social exchange theories, the mediating roles of psychological safety and felt obligation in the trust-engagement relationship were empirically investigated in the Malaysian context. Using self-report questionnaires, data were collected from 337 nurses employed in a public hospital located near Kuala Lumpur, Malaysia. Results fully supported the proposed serial multiple mediator model. Trust in supervisor was indirectly related to job engagement via psychological safety followed by felt obligation. This study provides empirical evidence that trust in supervisor makes employees feel psychologically safe to employ and express their selves in their job roles. This satisfaction of the psychological safety need is interpreted by employees as an important socioemotional benefit that, in turn, makes them feel obligated to pay back to their organization through their enhanced level of job engagement. Implications for theory and practice were discussed. 相似文献

In multiple regression researchers often follow up significant tests of the interaction between continuous predictors X and Z with tests of the simple slope of Y on X at different sample-estimated values of the moderator Z (e.g., ±1 SD from the mean of Z). We show analytically that when X and Z are randomly sampled from the population, the variance expression of the simple slope at sample-estimated values of Z differs from the traditional variance expression obtained when the values of X and Z are fixed. A simulation study using randomly sampled predictors compared four approaches: (a) the Aiken and West (1991) test of simple slopes at fixed population values of Z, (b) the Aiken and West test at sample-estimated values of Z, (c) a 95% percentile bootstrap confidence interval approach, and (d) a fully Bayesian approach with diffuse priors. The results showed that approach (b) led to inflated Type 1 error rates and 95% confidence intervals with inadequate coverage rates, whereas other approaches maintained acceptable Type 1 error rates and adequate coverage of confidence intervals. Approach (c) had asymmetric rejection rates at small sample sizes. We used an empirical data set to illustrate these approaches. 相似文献
