Reduction of faking with the use of a forced-choice personality test: Cross-cultural comparisons between South Korea and the United States

Forced-choice format tests have been suggested as an alternative to Likert-scale measures for personnel selection due to robustness to faking and response styles. This study compared degrees of faking occurring in Likert-scale and forced-choice five-factor personality tests between South Korea and the United States. Also, it was examined whether the forced-choice format was effective at reducing faking in both countries. Data were collected from 396 incumbents participating in both honest and applicant conditions (N_SK = 179, N_US = 217). Cohen's d values for within-subjects designs (ds_within) for between the two conditions were utilized to measure magnitudes of faking occurring in each format and country. In both countries, the degrees of faking occurring in the Likert-scale were larger than those from the forced-choice format, and the magnitudes of faking across five personality traits were larger in South Korea by from 0.07 to 0.12 in ds_within. The forced-choice format appeared to successfully reduce faking for both countries as the average ds_within decreased by 0.06 in both countries. However, the patterns of faking occurring in the forced-choice format varied between the two countries. In South Korea, degrees of faking in Openness and Conscientiousness increased, whereas those in Extraversion and Agreeableness were substantially decreased. Potential factors leading to trait-specific faking under the forced-choice format were discussed in relation to cultural influence on the perception of personality traits and score estimation in Thurstonian item response theory (IRT) models. Finally, the adverse impact of using forced-choice formats on multicultural selection settings was elaborated.     

无关负性信息对复发性抑郁缓解者工作记忆内容更新的影响

摘 要 采用改编后的Sternberg 任务考查无关负性信息对复发性抑郁缓解个体工作记忆内容更新的影响。与正常组相比,缓解期个体在无关负性条件下对探测图片的反应时要长于有关负性条件下的反应时,而正常个体在无关正性探测图片的反应时明显长于有关正性条件下的反应时。同时缓解期个体在无关负性条件下对探测图片的反应时明显长于新图条件下的反应时,出现明显的干扰效应。结果表明反复发作的抑郁缓解者在摒弃工作记忆中无关负性内容时存在障碍。     

并列和偏正结构双字合成词的注视位置效应

采用EyeLink II眼动仪, 选取并列结构和偏正结构两种类型的目标词, 要求大学生被试阅读包含有目标词的句子, 以探讨两种双字合成词的注视位置效应。结果发现：在阅读并列和偏正结构的目标词时, 单次注视条件下读者往往将首次注视定位于词的中心位置, 多次注视时首次注视往往落在词的开端部分; 当首次注视落在词的开端时再注视该词的概率增加, 而且再注视往往落在词的结尾部分。结果提示：在单次注视条件下存在偏向注视位置; 双字合成词结构不影响偏向和最佳注视位置; 研究结果支持“战略-战术”模型。     

汉字笔画数对注视位置效应的影响

采用EyeLink 2000眼动仪,选取四种不同类型的双字词（首字和尾字均为多笔画汉字;首字为多笔画汉字,尾字为少笔画汉字;首字为少笔画汉字,尾字为多笔画汉字;首字和尾字均为少笔画汉字）,要求被试阅读包含有目标词的句子,以探讨汉字笔画数对注视位置效应的影响。结果发现,单次注视条件下,读者往往将首次注视定位于词的中心位置,多次注视时首次注视往往落在词的开头部分;但是当首字为多笔画汉字时,相较于首字为少笔画汉字,读者对目标词的首次注视更多地落在词的首字上。首字和尾字笔画数共同影响读者对目标词的再注视概率。研究结果支持“战略-战术”模型。     

四卡问题的视角效应发生机制：领域一般性还是领域特殊性？

视角效应（Perspective Effects)是指四卡问题解决中,当被试从不同的角度对条件规则进行检验时,其选择偏向会在卡片p,q和-p,q之间发生稳定变化的现象。视角效应对四卡问题的解决有重要影响,但其存在条件及发生机制仍存在争议。本研究通过3个实验,探讨四卡问题中的视角效应。实验1和实验2采用混合实验设计,结果表明,转换社会契约、因果规则的四卡问题中,发现视角效应,抽象规则中,提供反例比提供充分必要条件更有利于产生视角效应。实验3在不同视角下研究四卡问题与条件推理的关系。结果表明,四卡问题与条件推理之间不具有逻辑一致性,产生分离现象。总之,视角效应在抽象规则和特定规则中均存在,而提供反例更有利于视角效应的产生。领域一般性或领域特殊性均不能有效解释视角效应的产生,两种机制的综合调节为解释视角效应提供新的角度。     

Survival of the Fittest: Rhetoric During the Course of an Election Campaign

Despite the tradition of studying campaign effects, we know little about the rhetorical strategies of candidates. This study speculates about the types of appeals that incumbents and challengers find most effective and that are, as a result, most likely to dominate an election campaign. Candidates have an incentive to use arguments that evoke emotions such as fear, anxiety, and anger. Emotional appeals allow candidates to emphasize consensual values, which makes it easier to mobilize their party's base while simultaneously attracting the support of the uncommitted. The use of emotional appeals is also consistent with the media's preference for drama and excitement in news reporting. Thus, emotional appeals will be more enduring than other types of appeals, and hence more likely to dominate the rhetorical landscape. A content analysis of newspaper coverage of the 1988 Canadian federal election campaign provides suggestive evidence in favor of this view.     

Decision framing: moderating effects of individual differences and cognitive processing

Two studies examined the effect of an individual difference variable, need for cognition (NC), and processing of the options on the occurrence of risky choice framing effects. In Study 1 (N=206), frame interacted with NC and math skill such that no framing effect was observed among those high in both NC and math skill. No effect was found for the processing manipulation of requesting a reason for one's choices. Study 2 (N=257) enhanced the processing of the problems by asking participants to write out the options as they would describe them to a friend. Results showed that frame interacted with NC and depth of processing such that no framing effect was observed among those high in NC who were in the deep processing condition. These findings suggest that NC and depth of processing need to be considered in concert in order to understand their moderating effects on framing. Copyright © 2004 John Wiley & Sons, Ltd.     

Methodological Issues in the Assessment of Medication Effects in Children Diagnosed with Attention Deficit Hyperactivity Disorder (ADHD)

Attention deficit hyperactivity disorder (ADHD) is one of the most commonly diagnosed disorders in school-aged children and is usually treated with stimulant medications, including methylphenidate (MPH; Ritalin®, Ritalin-LA®, Concerta®, Metadate®, or Focalin®) and other drug compounds (e.g., Adderall®, Adderall-XR®, or Dexedrine). Assessment of school behavior and performance is a critical component in determining the safety and efficacy of these medications. This paper reviews methodological issues in assessing drug effects in school settings by considering features of the independent variable (the medication), the dependent variables (the endpoints selected for assessment), and the design (the structure of the assessment). In addition, we consider recent conceptual advances in understanding the behavioral mechanisms of action of drugs used to treat ADHD that may influence the structure and interpretation of medication assessments.     

Diagnostic causal reasoning with verbal information

In diagnostic causal reasoning, the goal is to infer the probability of causes from one or multiple observed effects. Typically, studies investigating such tasks provide subjects with precise quantitative information regarding the strength of the relations between causes and effects or sample data from which the relevant quantities can be learned. By contrast, we sought to examine people’s inferences when causal information is communicated through qualitative, rather vague verbal expressions (e.g., “X occasionally causes A”). We conducted three experiments using a sequential diagnostic inference task, where multiple pieces of evidence were obtained one after the other. Quantitative predictions of different probabilistic models were derived using the numerical equivalents of the verbal terms, taken from an unrelated study with different subjects. We present a novel Bayesian model that allows for incorporating the temporal weighting of information in sequential diagnostic reasoning, which can be used to model both primacy and recency effects. On the basis of 19,848 judgments from 292 subjects, we found a remarkably close correspondence between the diagnostic inferences made by subjects who received only verbal information and those of a matched control group to whom information was presented numerically. Whether information was conveyed through verbal terms or numerical estimates, diagnostic judgments closely resembled the posterior probabilities entailed by the causes’ prior probabilities and the effects’ likelihoods. We observed interindividual differences regarding the temporal weighting of evidence in sequential diagnostic reasoning. Our work provides pathways for investigating judgment and decision making with verbal information within a computational modeling framework.
