The Use of Mobile Devices in High‐stakes Remotely Delivered Assessments and Testing

With Internet access no longer restricted to desktop and laptop computers, job applicants now have the opportunity to complete remotely delivered assessments on mobile, handheld small screen devices such as smartphones, and personal digital assistants. In this study, a large dataset is used to investigate demographic and score differences between job applicants who completed a remotely delivered high‐stakes assessment on a mobile device and those who completed it on a nonmobile device. Based on a sample of 3,575,207 job applicants who completed an unproctored Internet‐based assessment between January 2011 and April 2012, the percentage of applicants completing the assessment on a mobile device was small, 1.93%, but nevertheless represented more than 69,000 people. Overall, there were small test‐taker demographic differences in the use of mobile devices versus nonmobile devices in that mobile devices were slightly more likely to be used by women, African‐Americans and Hispanics, and younger applicants. Scores on a personality measure were similar for mobile and nonmobile devices but scores on a general mental ability test were substantially lower for mobile devices. Tests of measurement invariance also indicated equivalence across the mobile and nonmobile samples. Test taker and organizational implications for completing remotely delivered high‐stakes noncognitive and cognitive assessments on mobile versus nonmobile devices are discussed.     

社会知觉视角下道德诉求方式如何提升劝捐效果

如何有效地引导个体“慷慨解囊”一直是理论和实践都关注的热点。基于道德基础理论和刻板印象内容模型, 研究考察了在不同社会知觉(温暖型vs.能力型)的劝捐主体中, 两种道德诉求方式(个体人道诉求vs.群体规范诉求)对劝捐效果的影响及其内在机制。3个实验的结果显示：温暖型(能力型)劝捐主体与个体人道诉求(群体规范诉求)更为契合, 更有利于提升劝捐效果; 温暖型劝捐主体进行个体人道诉求主要通过唤起个体的自我效能而提升劝捐效果, 而能力型劝捐主体进行群体规范诉求则主要通过增强个体的反应效能而提升劝捐效果。     

Differentiation of Self,Mate Selection,and Marital Adjustment: Validity of Postulates of Bowen Theory in a Spanish Sample

This research investigates relationships between differentiation of self, mate selection, and marital adjustment in a Spanish sample of 118 heterosexual couples (N = 236). In line with Bowen theory, greater differentiation of self and greater similarity in partners' differentiation of self levels each predicted greater marital adjustment. Contrary to theory, gender differences were observed on the S-DSI, with males showing higher total differentiation scores than females, and hypothesized links between differentiation of self and mate selection were not observed. Implications for therapy and suggestions for future research with the S-DSI are discussed.     

The comparative effectiveness of distributed and colocated team after-action reviews

Despite their frequent use in the military and private sectors, the comparative effectiveness of colocated and distributed after-action reviews (AARs) is relatively unknown. Consequently, this study examined the comparative effectiveness of colocated and distributed AARs across taskwork and teamwork outcomes. Data were obtained from 492 participants randomly assigned to 123 four-person teams who participated in one of six AAR conditions. The results indicated that teams in the AAR conditions had significantly higher performance and team efficacy scores than the teams in the non-AAR conditions. In summary, the findings highlight that regardless of the training environment or type of AAR, the AAR remains an effective method at increasing performance and other outcomes. Therefore, the use of distributed AARs does not engender the posited process losses that were hypothesized.     

Ethical Requirements and Responsibilities in Video Methodologies: Considering Confidentiality and Representation in Social Justice Research

In recent years, psychologists have begun to use video more frequently in qualitative research, in particular, within research on social justice. The non‐confidential nature inherent in video, however, raises new ethical challenges for the field of psychology to address. Building upon a growing literature on video‐based research, in this article, we use an illustrative case study to examine how researchers' sense of ethical responsibility can find guidance from, clash against, or fill gaps left by extant federal and disciplinary ethical requirements. We focus specifically on issues of confidentiality and representation, highlighting the challenges and possibilities that video creates in relation to participants' power, dignity, and participation and arguing that psychologists must systematically engage questions about ethical responsibilities throughout the design and implementation phases of a research project. In doing so, psychologists, their community partners, and students will be better able to articulate and problematize their assumptions and intentions regarding video work.     

Supererogation and conditional obligation

Philosophical Studies - There are plenty of classic paradoxes about conditional obligations, like the duty to be gentle if one is to murder, and about “supererogatory” deeds beyond the...     

Assessing the Impact of Relative Social Position and Absolute Community Resources on Depression and Obesity Among Smokers

We tested two competing hypotheses-relative social position and community resources-in regards to their effect on two co-occurring health problems (depression, and obesity) in a sample of smokers participating in an online smoking cessation intervention. Income and education data at the zip code level from the 2000 Census was linked with individual level data. Logistic regression models were used for each co-occurring problem to determine how each SES variable (individually and interactively) was associated with the presence of co-occurring health problems. We found that lower individual education was related to poorer health for all outcomes (Depression: OR = 1.25; Obesity: OR = 1.24; Both: OR = 1.46), lower community education was only related to obesity (OR = 1.20). Lower individual income was related to higher rates of depressive symptoms (OR = 1.64) and both health problems (OR = 1.55); a significant interaction of individual and community income (Wald = 6.13, p < .05) revealed that high income individuals were less likely to be depressed if they lived in lower-income communities and became more likely to be so as community income increased. Relative social position was confirmed for depression, whereas community resources were prominent only for obesity. Higher individual education most consistently predicted positive health outcomes, making it a potentially powerful target to reduce health disparities.     

Who is good at this game? Linking an activity to a social category undermines children's achievement

Children's achievement-related theories have a profound impact on their academic success. Children who adopt entity theories believe that their ability to perform a task is dictated by the amount of natural talent they possess for that task--a belief that has well-documented adverse consequences for their achievement (e.g., lowered persistence, impaired performance). It is thus important to understand what leads children to adopt entity theories. In the experiments reported here, we hypothesized that the mere act of linking success at an unfamiliar, challenging activity to a social group gives rise to entity beliefs that are so powerful as to interfere with children's ability to perform the activity. Two experiments showed that, as predicted, the performance of 4- to 7-year-olds (N = 192) was impaired by exposure to information that associated success in the task at hand with membership in a certain social group (e.g., "boys are good at this game"), regardless of whether the children themselves belonged to that group.
