A Meta-Analysis of Research on Hindsight Bias

We conducted a meta-analysis of research on hindsight bias to gain an up-to-date summary of the overall strength of hindsight effects and to test hypotheses about potential moderators of hindsight distortion. A total of 95 studies (83 published and 12 unpublished) were included, and 252 independent effect sizes were coded for moderator variables in 3 broad categories involving characteristics of the study, of measurement, and of the experimental manipulation. When excluding missing effect sizes, the overall mean effect size was Md = .39 with a 95% confidence interval of .36 to .42. Five main findings emerged: (a) effect sizes calculated from objective probability estimates were larger than effect sizes calculated from subjective probability estimates; (b) effect sizes of studies that used almanac questions were larger than effect sizes of studies that used real-world events or case histories; (c) studies that included neutral outcomes resulted in larger effect sizes than studies that used positive or negative outcomes; (d) studies that included manipulations to increase hindsight bias resulted in significantly larger effect sizes than studies in which there were no manipulations to reduce or increase hindsight bias; and (e) studies that included manipulations to reduce hindsight bias did not produce lower effect sizes. These findings contribute to our understanding of hindsight bias by updating the state of knowledge, widening the range of known moderator variables, identifying factors that may activate different mediating processes, and highlighting critical gaps in the research literature.     

Competitive Fighting between Mice with Different Hereditary Backgrounds

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 (29 boys, 23 girls) 6-year-olds from a variety of socioeconomic backgrounds. The instrument had 32 frames, each of which had three red or blue objects, some of regular and some of irregular shape. After color or form dominance for each child was established, frames were presented in which the dominant dimension could be chosen only through cognitive reorganization. Indications of cognitive reorganization for form-processing children included switching to color choices when all three objects were of identical shape, taking significantly (p < .05) greater time to make a choice for irregularly shaped objects, and having judges find indications of the use of parts of irregularly shaped objects for matches in verbal explanations by each child.     

The development of work discussion groups in educational settings

This paper describes the application and development of the work discussion method within educational settings. In the first section of the paper, I outline some key contextual factors that are important to consider when setting up work discussion groups within schools. A number of case examples are then described, illustrating a range of central issues that can emerge. By developing a deeper understanding about the meaning of behaviour and the emotional factors that impact on teaching and learning, I hope to demonstrate how work discussion groups can help teachers to develop their capacity to manage the challenges of their work, role and relationships with pupils. More broadly, I hope to illustrate how these groups can help to promote a learning environment for all, in which development and growth is promoted at a personal, professional and whole school level.     

Client and therapist variability in clients' perceptions of their therapists' multicultural competencies

This study examined therapist differences in their clients' ratings of their therapists' multicultural competencies (MCCs) as well as tested whether therapists' who were rated as exhibiting more MCCs also had clients who had better therapy outcomes (N = 143 clients and 31 therapists). All clients completed at least 3 sessions. Results demonstrated that therapists accounted for less than 1% of the variance in their clients' Cross-Cultural Counseling Inventory–Revised (CCCI-R; T. D. LaFromboise, H. L. K. Coleman, & A. Hernandez, 1991) scores, suggesting that therapists did not differ in terms of how clients rated their MCCs. Therapists accounted for approximately 8.5% of the variance in therapy outcomes. For each therapist, their clients' CCCI-R scores were aggregated to provide an estimate of therapists' MCCs. Therapists' MCCs, based on aggregate CCCI-R scores, did not account for the variability in therapy outcomes that were attributed to them. Additionally, clients' race/ethnicity, therapists' race/ethnicity, or the interaction of clients'–therapists' race/ethnicity were not significantly associated with clients' perceptions of their therapists' MCCs.     

How do depressed and healthy adults interpret nuanced facial expressions?

This study investigates the discrimination accuracy of emotional stimuli in subjects with major depression compared with healthy controls using photographs of facial expressions of varying emotional intensities. The sample included 88 unmedicated male and female subjects, aged 18-56 years, with major depressive disorder (n = 44) or no psychiatric illness (n = 44), who judged the emotion of 200 facial pictures displaying an expression between 10% (90% neutral) and 80% (nuanced) emotion. Stimuli were presented in 10% increments to generate a range of intensities, each presented for a 500-ms duration. Compared with healthy volunteers, depressed subjects showed very good recognition accuracy for sad faces but impaired recognition accuracy for other emotions (e.g., harsh, surprise, and sad expressions) of subtle emotional intensity. Recognition accuracy improved for both groups as a function of increased intensity on all emotions. Finally, as depressive symptoms increased, recognition accuracy increased for sad faces, but decreased for surprised faces. Moreover, depressed subjects showed an impaired ability to accurately identify subtle facial expressions, indicating that depressive symptoms influence accuracy of emotional recognition.     

Two ways,two steps

Joseph Ratzinger’s theology of religions is structured around a basic choice between “the two ways” of “a personal understanding of God” and “a mysticism of identity.” After clarifying misunderstandings about a possible “third way,” this article examines Ratzinger’s treatment of the two ways with the help of Roman A. Siebenrock’s observation that Ratzinger’s thought proceeds in two steps, the first highlighting differences, the second seeking integration. In the first step, Ratzinger defends the personal understanding of God on the basis of the primacy of love, the inviolable dignity of the human person, and the real distinction between good and evil. In the second step, Ratzinger shows considerable openness toward “interreligious ecumenism” between the two ways, emphasising the decisive importance of the mystical and apophatic aspect of religion. A similar dynamic is seen in the treatment of prayer, although in this case the second step remains underdeveloped. Ratzinger is cautious about multireligious prayer and pessimistic about interreligious prayer. Nonetheless, neither is unconditionally rejected, and the door is left open for further developments and discussion. This article suggests that interreligious families, missionary situations and prayers to saints could provide examples of acceptable instances of interreligious prayer.     

Youth Action Research for Prevention: A Multi-level Intervention Designed to Increase Efficacy and Empowerment Among Urban Youth

Youth Action Research for Prevention (YARP), a federally funded research and demonstration intervention, utilizes youth empowerment as the cornerstone of a multi-level intervention designed to reduce and/or delay onset of drug and sex risk, while increasing individual and collective efficacy and educational expectations. The intervention, located in Hartford Connecticut, served 114 African-Caribbean and Latino high school youth in a community education setting and a matched comparison group of 202 youth from 2001 to 2004. The strategy used in YARP begins with individuals, forges group identity and cohesion, trains youth as a group to use research to understand their community better (formative community ethnography), and then engages them in using the research for social action at multiple levels in community settings (policy, school-based, parental etc.) Engagement in community activism has, in turn, an effect on individual and collective efficacy and individual behavioral change. This approach is unique insofar as it differs from multilevel interventions that create approaches to attack multiple levels simultaneously. We describe the YARP intervention and employ qualitative and quantitative data from the quasi-experimental evaluation study design to assess the way in which the YARP approach empowered individual youth and groups of youth (youth networks) to engage in social action in their schools, communities and at the policy level, which in turn affected their attitudes and behaviors.
