Does the presentation of multiple facial composites improve suspect identification?

Previous research that has evaluated the accuracy of facial composites has reported low identification rates. Two studies are reported here that consider whether showing more than one composite of the same suspect might improve the rate of identification. Sixteen participant‐witnesses saw one of two staged events, each involving a different unfamiliar target. Each participant‐witness worked with a police operator to construct a composite of the target they had seen. One, four or eight composites depicting the same target were then shown to individuals familiar with the target. Overall, the results showed that presenting more than one composite increased the rate of identification. In addition, the results of Study 2 suggest that if the police must select just one composite from a number produced by witnesses, then a promising method might be to choose the one which bears most similarity to the other composites in the set.

Applicant Reactions in Selection: Comprehensive meta‐analysis into reaction generalization versus situational specificity

This paper reports a comprehensive quantitative summary into applicant reactions to popular methods of employee selection. A detailed search of published and unpublished studies resulted in a final sample (k) of 38 independent samples covering 10 popular candidate assessment methods. Applicant reactions primary studies included samples from 17 countries internationally. Counter to previous suggestions for the situational specificity of applicant reactions, findings showed considerable similarity supporting the reaction generalizability hypothesis. Reaction favorability was structurally similar across countries and revealed a three‐tier clustering of overall favorability perceptions –most preferred (work samples, interviews), favorably evaluated (resumes, cognitive tests, references, biodata, personality inventories), and least preferred (honesty tests, personal contacts, graphology). Some differences in applicant reactions to dimension‐specific perceptions were found, however. Further analyses revealed strong positive correlations between favorability ratings and their validity and international usage. Implications for future research and ramifications for practice are considered in conclusion.     

Reasons for Being Selective When Choosing Personnel Selection Procedures

The scientist–practitioner gap in personnel selection is large. Thus, it is important to gain a better understanding of the reasons that make organizations use or not use certain selection procedures. Based on institutional theory, we predicted that six variables should determine the use of selection procedures: the procedures' diffusion in the field, legal problems associated with the procedures, applicant reactions to the procedures, their usefulness for organizational self‐promotion, their predictive validity, and the costs involved. To test these predictions, 506 HR professionals from the German‐speaking part of Switzerland filled out an online survey on the selection procedures used in their organizations. Respondents also evaluated five procedures (semi‐structured interviews, ability tests, personality tests, assessment centers, and graphology) on the six predictor variables. Multilevel logistic regression was used to analyze the data. The results revealed that the highest odd ratios belonged to the factors applicant reactions, costs, and diffusion. Lower (but significant) odds ratios belonged to the factors predictive validity, organizational self‐promotion, and perceived legality.     

When can information from ordinal scale variables be integrated?

Many theoretical constructs of interest to psychologists are multidimensional and derive from the integration of several input variables. We show that input variables that are measured on ordinal scales cannot be combined to produce a stable weakly ordered output variable that allows trading off the input variables. Instead a partial order is obtained in which the amount of ordering depends on the number and nature of the input variables and the relationship between them. However, if trade-offs are excluded, it is still possible to obtain a weak order using lexicographic ordering of the input variables. An implication is that psychological processes that integrate information from different input variables and that produce consistent output require that the input variables be measured on more than ordinal scales. A further implication is that the level of measurement of the input variables affects the kind of psychological model that can be applied to the process.     

A probabilistic model of theory formation

Concept learning is challenging in part because the meanings of many concepts depend on their relationships to other concepts. Learning these concepts in isolation can be difficult, but we present a model that discovers entire systems of related concepts. These systems can be viewed as simple theories that specify the concepts that exist in a domain, and the laws or principles that relate these concepts. We apply our model to several real-world problems, including learning the structure of kinship systems and learning ontologies. We also compare its predictions to data collected in two behavioral experiments. Experiment 1 shows that our model helps to explain how simple theories are acquired and used for inductive inference. Experiment 2 suggests that our model provides a better account of theory discovery than a more traditional alternative that focuses on features rather than relations.     

How can mindfulness be promoted? Workload and recovery experiences as antecedents of daily fluctuations in mindfulness

While previous work on mindfulness has focused predominantly on the benefits of mindfulness and of mindfulness interventions, the present article addresses the question of how natural experiences of mindfulness can be promoted in the context of work. Accordingly, this article sheds light on day‐to‐day fluctuations in workload and recovery experiences (psychological detachment and sleep quality) as antecedents of state mindfulness. Furthermore, this study extends extant research that has documented beneficial effects of mindfulness on subsequent recovery experiences by arguing that the relationship between mindfulness and recovery experiences is reciprocal rather than unidirectional. Using an experience‐sampling design across five workdays and involving three daily measurement occasions, we found that sleep quality and workload were related to subsequent levels of mindfulness. While not displaying a significant direct relationship with mindfulness, psychological detachment was indirectly related to mindfulness via sleep quality. Fatigue was identified as an important mechanism explaining these relationships. Furthermore, findings confirmed that the relationship between mindfulness and recovery experiences is reciprocal rather than unidirectional. Taken together, this study contributes to an enriched understanding of the role of mindfulness in organizations by shedding light on factors that precede the experience of mindfulness and by pointing to the existence of gain spirals associated with recovery experiences and mindfulness.

Practitioner points

• Organizations seeking to promote mindfulness among their workforce should try to keep workload to a manageable degree.
• Organizations may also pay attention to care for employees' day‐to‐day recovery as it has been shown to facilitate mindfulness.

     

Economic Predictors of Differences in Interview Faking Between Countries: Economic Inequality Matters,Not the State of Economy

Many companies recruit employees from different parts of the globe, and faking behavior by potential employees is a ubiquitous phenomenon. It seems that applicants from some countries are more prone to faking compared to others, but the reasons for these differences are largely unexplored. This study relates country-level economic variables to faking behavior in hiring processes. In a cross-national study across 20 countries, participants (N = 3,839) reported their faking behavior in their last job interview. This study used the random response technique (RRT) to ensure participants’ anonymity and to foster honest answers regarding faking behavior. Results indicate that general economic indicators (gross domestic product per capita [GDP] and unemployment rate) show negligible correlations with faking across the countries, whereas economic inequality is positively related to the extent of applicant faking to a substantial extent. These findings imply that people are sensitive to inequality within countries and that inequality relates to faking, because inequality might actuate other psychological processes (e.g., envy) which in turn increase the probability for unethical behavior in many forms.     

Traumatische Trauer – ein eigenständiges Krankheitsbild?

Grief is a highly individualized process influenced by intrapsychic, interpersonal and social factors. The definition of normal and pathological grief is complicated by the variety of grief reactions. Empirical research indicates that pathological grief may be concerned considered as a separate entity. Two research groups developed empirically validated criteria with a special focus on the traumatic aspect of grief. The current state of research allows, however, in our opinion not the conclusion, that the proposed diagnostic criteria for complicated (Horowitz et al. 1997) or traumatic grief (Prigerson et al. 1999b) do not enclose all types of grief. Further empirical research on representative samples is necessary to validate previous findings and to differentiate specific subgroups of pathological grief.
