Effects of reiteration,hindsight bias,and memory on realism in eyewitness confidence

This study investigated the effects of repetition, memory, feedback, and hindsight bias on the realism in confidence in answers to questions on a filmed kidnapping. In Experiment 1 the participants showed overconfidence in all conditions. In the Repeat condition (‘how confident are you now that your previous answers are correct’) overconfidence was reduced as a consequence of the decrease in confidence in both correct and incorrect answers compared with the Repeat condition when the participants received feedback on their answers and were asked to remember their initial confidence, the confidence level was higher for correct and lower for incorrect answers. In Experiment 2, recalled confidence (the Memory condition) increased compared with the original confidence both for correct and incorrect answers; the effect of this was increased overconfidence. The Hindsight condition showed a decrease in confidence in incorrect answers. The results suggest that a unique hindsight effect may be more clearly present for incorrect than for correct answers. Our study gives further evidence for the malleability of the realism in eyewitness confidence and we discuss both the theoretical and forensic implications of our findings.

A new quantile estimator with weights based on a subsampling approach

Quantiles are widely used in both theoretical and applied statistics, and it is important to be able to deploy appropriate quantile estimators. To improve performance in the lower and upper quantiles, especially with small sample sizes, a new quantile estimator is introduced which is a weighted average of all order statistics. The new estimator, denoted NO, has desirable asymptotic properties. Moreover, it offers practical advantages over four estimators in terms of efficiency in most experimental settings. The Harrell–Davis quantile estimator, the default quantile estimator of the R programming language, the Sfakianakis–Verginis SV2 quantile estimator and a kernel quantile estimator. The NO quantile estimator is also utilized in comparing two independent groups with a percentile bootstrap method and, as expected, it is more successful than other estimators in controlling Type I error rates.     

An Examination of the Biblical Evidence for Open Theism

Open Theist theologians argue that their view of divine foreknowledge and providence is the correct interpretation of the Bible, and suggest some biblical evidence to support this claim. Among these theologians, Gregory A. Boyd’s case is the most systematic, and also the most comprehensive and rigorous. Taking into consideration (1) the main philosophical claims of Open Theism and its main rivals, namely Calvinism and Molinism, and (2) Open Theist theologians’ interpretative principles for the Bible, the biblical evidence for Open Theism suggested by Boyd can be classified into three groups according to their strength. I will argue that the first group of themes has no evidential value for Open Theism, since these themes can be interpreted just as plausibly from a Calvinist or Molinist perspective. By contrast, the second group of themes has some evidential value and thus constitutes prima facie evidence for Open Theism, since these themes make most sense under an Open Theist interpretation. However, these themes also make some sense on a Molinist reading. The third group of themes, I argue, has most evidential value for Open Theism, since it seems hard to reconcile these themes either with Calvinism or Molinism.

Uncovering the trail of positive affect in the job attitudes literature: A systematic review

A review of the organisational psychology literature suggests that researchers have examined at least four job attitude constructs: job satisfaction, work/task satisfaction, job involvement, and organisational commitment. Less, however, is known about why the four different job attitudes vary in magnitude as predictors of vital organisational outcomes. In this systematic review, I propose that positive affect is central in explaining the differential effects of these job attitudes on organisational outcomes. The review then explicates patterns of results underlying prior studies on these job attitudes and presents an overarching proposition: Accurate conceptualisation and measurement of the affective component underlying each job attitude will help illustrate how, and to what extent, each job attitude leads to desirable organisational outcomes. Finally, four key suggestions for further job attitudes research are presented: (a) enhancing conceptualisation and measurement of positive affect in job attitudes, (b) developing an overarching theory of positive affect, (c) focusing on discrete positive emotions, and (d) looking beyond existing current job attitude constructs. This work complements the current affective epoch of job attitudes research, uncovering the trail of positive affect as it has informed the job attitudes literature historically and suggesting its theoretical and practical developments for the future.     

Positive Psychological States and Employee Creativity: The role of Ethical Leadership

This study explores a new theoretical model of employee creativity by investigating the impact of ethical leadership on creativity mediated by creative self-efficacy and psychological safety. Data collected from 200 supervisor–subordinate dyads in Pakistan reveal that ethical leadership is positively related to creativity. Further, psychological safety partially mediates the relationship between ethical leadership and creativity. However, creative self-efficacy is found insignificant in the relationship between ethical leadership and creativity. The study discusses research and practical implications of the proposed new theoretical framework with regard to employee creativity.
