Automatic identification of storytelling responses to past-behavior interview questions via machine learning

Structured interviews often feature past-behavior questions, where applicants are asked to tell a story about past work experience. Applicants often experience difficulties producing such stories. Automatic analyses of applicant behavior in responding to past-behavior questions may constitute a basis for delivering feedback and thus helping them improve their performance. We used machine learning algorithms to predict storytelling in transcribed speech of participants responding to past-behavior questions in a simulated selection interview. Responses were coded as to whether they featured a story or not. For each story, utterances were also manually coded as to whether they described the situation, the task/action performed, or results obtained. The algorithms predicted whether a response features a story or not (best accuracy: 78%), as well as the count of situation, task/action, and response utterances. These findings contribute to better automatic identification of verbal responses to past-behavior questions and may support automatic provision of feedback to applicants about their interview performance.     

Backlash for high self-promotion at hiring depends on candidates' gender and age

Previous research has shown that evaluators react negatively to intense, high levels of self-promotion during the interview, in particular when displayed by female candidates, presumably because these behaviors violate the female gender stereotype of being modest and putting others first. We expand this focus on a single social category and examine the joint effects of gender and age on reactions to high self-promotion/low modesty, as both gender and age stereotypes contain normative expectations regarding assertiveness and humility. Results of our experimental study point out two groups at risk of backlash, older women and younger men. While both older female and younger male candidates engaging in high self-promotion were seen as competent, they were regarded as less interpersonally warm, received lower interview performance ratings, and were less likely to be hired. These results provide evidence for the importance of applying an intersectional lens on the effects of self-promotion at hiring. Their implications for theory and practice as well as recommendations for future research are discussed.     

Thou Shalt not Lie! Exploring and testing countermeasures against faking intentions and faking in selection interviews

Many applicants use faking in interviews to present themselves more favorably than they really are. There is widespread concern that this may affect interview validity. As previous research on countermeasures is sparse, we conducted an exploratory study to identify the most promising countermeasures. For technology-mediated interviews, these were warnings referring to a criterion-based content analysis and lie detection algorithms focusing on nonverbal or paraverbal cues. For face-to-face interviews, these were objective questions and a personable interviewer. We then investigated the effects of these countermeasures on faking intentions in two experimental vignette studies and on faking in another simulated interview study. However, none of the countermeasures could reduce faking intentions or faking. Additionally, in the vignette studies, warnings impaired applicant reactions.     

基于CD-CAT的多策略RRUM模型及其选题方法开发

在有多种解题策略的认知诊断问题情境中, 用每个Q矩阵表示一种解题策略, 由此将单策略认知诊断RRUM模型拓广为多策略RRUM模型(MS-RRUM)。随后, 在应用MS-RRUM模型的CD-CAT中开发了适用于多策略情境的MAP参数估计法和多策略香农熵(MSSHE)选题法。将MSSHE选题法与随机选题法分别在不同属性数量、不同测验长度下进行比较, 结果发现前者对被试的策略和认知状态判准率都显著优于后者, 而且都很理想。这样就顺利实现了在CD-CAT做策略诊断的目标。     

汉语言语产生中的词长效应

采用启动条件下的词汇命名和图片命名范式, 探讨在汉语言语产生中词长效应的产生机制, 考察概念激活、词条提取和语音编码对词长效应的影响。实验1和实验2表明, 词条提取过程并不影响在词汇命名中的词长效应, 支持多词素词整词通达表征的理论。实验3显示, 概念激活和语音编码共同影响在图片命名中的词长效应, 被试对长词的命名时间显著地长于对短词的命名时间, 对下属水平概念的词汇提取显著地慢于对基本水平概念的词汇提取。研究结果支持多词素词语音编码的序列性和基本水平类别优先习得的观点。     

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。     

Development of co-feeding behavior in young wild Japanese macaques (Macaca fuscata)

This study describes the developmental course of the social context of feeding behavior in infants and yearlings of Japanese macaques in a provisioned free-ranging troop. Results of this longitudinal study revealed that infants and yearlings exhibited synchronous feeding behavior in the majority of cases in which they had feeding neighbors within 1 m. They consistently showed feeding behavior more often when their closest neighbor fed than when they did not. In feeding situations, infants tended mainly to be in close proximity with their mothers in the early stages of life and, later, also with peers. The results imply that potential opportunities for the social transmission of food selection habits are available for young Japanese macaques in the wild.     

Changes in Multidigit Synergies and Their Feed-Forward Adjustments in Multiple Sclerosis

The authors explored the changes in multidigit synergies in patients with multiple sclerosis (MS) within the framework of the uncontrolled manifold hypothesis. The specific hypotheses were that both synergy indices and anticipatory synergy adjustments prior to the initiation of a self-paced quick action would be diminished in the patients compared to age-matched controls. The MS patients and age-matched controls (n = 13 in both groups) performed one-finger and multifinger force production tasks involving both accurate steady-state force production and quick force pulses. The patients showed significantly lower maximal finger forces and a tendency toward slower force pulses. Enslaving was increased in MS, but only in the lateral fingers (index and little). Indices of multifinger synergies during steady-state force production were lower in MS, mainly due to the lower amount of intertrial variance that did not affect total force. Anticipatory synergy adjustments were significantly delayed in MS. The results show that MS leads to significant changes in multidigit synergies and feed-forward adjustments of the synergies prior to a quick action. The authors discuss possible contributions of subcortical structures to the impaired synergic control.     

Asymmetric peer selections among Blacks,Asians, and Whites in a virtual environment: Preliminary evidence for triangulated threat theory

Black, Asian, and White participants (N = 210) created self-resembling avatars and engaged in peer-selection tasks during social events in the virtual world, Second Life, that were designed to simulate various types of resource competition. Participants in merit-based resource competition settings had less diversity in their peer groups compared to participants in settings where no resource competition was present, and Asian participants had lower preference for Black peers. Furthermore, these relationships were mediated by out-group discomfort. Results are discussed in relation to partial support for triangulated threat theory of group relations among Blacks, Asians, and Whites.
