Separating the confident from the correct: Leveraging member knowledge in groups to improve decision making and performance

Groups often struggle to distinguish expert members from others who stand out for various reasons but may not be particularly knowledgeable (Littlepage & Mueller, 1997). We examined an intervention designed to improve group decision making and performance through instructing group members to search for information they already possessed that was relevant to a problem. Participants estimated values and expressed their confidence in their estimates individually and then a second time either individually or in a group. This was done with or without the intervention. Results indicated that: (1) groups were more confident than, and out-performed, individuals, (2) group decision making was best captured by models predicting more influence for more accurate members when the intervention was used and more influence for more confident members in its absence, and (3) groups that received the intervention out-performed groups that did not.     

Mass psychology of the led and the leaders

Abstract

Some salient features of a Sullivanian perspective are given as a background for a discussion of the case of Anna. Lived experience is mentioned as of equal importance as fantasy. Technically, analytic inquiry in the form of questions is stressed. In his review of the case presentation, the author observes that too much emphasis is given to content, compared to form. He notes that the therapist does not report key transference and non-transference interactions with the patient and further suggests that the patient still has significant narcissistic problems. He suggests that it is time to confront the patient with her characterological ways of relating to the analyst.     

Child Personality as Moderator of Outcome in a School‐based Intervention for Preventing Externalising Behaviour

Studying moderators of intervention effects is essential to elucidate what works for whom. The present study investigated whether child personality moderates short‐term and follow‐up effects of an individualised preventive school‐based intervention for children with externalising behaviour. The sample consisted of 48 schools, with 264 fourth‐grade children displaying externalising behaviour (M_age = 10.2 years), randomly assigned to the intervention (n = 191) or no intervention control (n = 73) condition. Teachers and children reported at pretest, posttest and follow‐up test about reactive and proactive aggression. Child personality was assessed by teachers at pretest. Child conscientiousness moderated short‐term intervention effects, indicating that more organised and planful children benefited more from the intervention. Child extraversion moderated both short‐term and follow‐up intervention effects, with low extraverted children showing larger effects. These results affirm the importance of including personality as moderator of intervention effects in future studies, as interventions adapted to specific child traits might yield larger effects.

Correcting Big Five Personality Measurements for Acquiescence: An 18‐Country Cross‐Cultural Study

For groups of persons with low or medium levels of education, Big Five personality scales typically yield scores that poorly replicate the idealized Big Five factor pattern. On the basis of representative samples of German adults, Rammstedt et al. have demonstrated that correcting each person's score for acquiescence eliminates this problem. In the present 18‐country study using large samples representative of each country's adult population, we found that, in all cases, correcting for acquiescence did indeed improve the congruence of factor loadings with an idealized Big Five pattern. However, although this correction led to acceptably high correspondence levels in all countries classified as individualistic, this was not always true for non‐individualistic countries. Possible reasons for this finding are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Associations of Identity Dimensions with Big Five Personality Domains and Facets

Personality is among the most important factors contributing to individual differences in identity formation. However, previous studies mainly focused on broad personality domains and neglected more specific facets. In addition, it has only recently been recognized that identity formation is guided by multiple types of commitment and exploration. The present study aimed to remedy these limitations by relating the 30 personality facets of the NEO‐PI‐3 to five identity dimensions. In general, identity formation was especially facilitated by high levels of Conscientiousness and, to a lesser extent, also by high levels of Extraversion and low levels of Neuroticism. Openness and Agreeableness predicted greater involvement in both the positive side (i.e. exploration in breadth and depth) and negative side (i.e. ruminative exploration) of the exploration process. Personality facets and their overarching domains, as well as facets underlying the same domain, were often differentially associated with identity dimensions. Additionally, we found that some personality facets both have bright and dark sides, as they predicted both proactive identity work and a weakened sense of identity. Overall, the present study underscores the utility of multidimensional models of identity formation and points to the benefits of considering personality facets in addition to broad domains.

Personality Traits and Body Weight Measures: Concurrent and Across‐Time Associations

We tested the possibility that the five‐factor model of personality is associated with three measures of body weight and with changes in their levels over time and that these associations are gender specific. The study was conducted at two points of time, Time 1 (2664 participants) and Time 2 (1492 participants), over approximately 4 years, controlling for gender, age, education, and having a chronic disease. Body weight was assessed by body mass index, waist circumference, waist‐to‐hip ratio, and the five‐factor model by Saucier's Mini‐Markers. Cross‐sectional regression results indicated that conscientiousness was negatively associated with the three body weight measures, whereas neuroticism and extraversion were positively associated with the three body weight measures. The longitudinal regression results indicate that extraversion was associated with an increase in two of the body weight measures. Neuroticism was associated with increase in all three body weight measures and more strongly for women than for men. Openness was associated with a decrease in all three body weight measures for women, but this association was not significant for men. These findings help identify personality traits that lead to risk of weight gain and point to the modifying role of gender. Copyright © 2013 John Wiley & Sons, Ltd.     

Normative and Descriptive Models of Military Decisions to Deploy Precision Strike Capabilities

Precision strike capabilities represent a significant and highly controversial part of present day military operations. And yet, there is a surprising dearth of empirical research on military decision making in this domain. In this article, we therefore review different psychological perspectives on how these decisions can be made. Specifically, we compare the application of normative models of judgment and choice against the empirical research on human decision making, which suggests that people are more likely to employ heuristic strategies. We suggest that several features of decision tasks in the precision strike domain evoke the use of intuitive (heuristic) decision making whereas other features such as the sometimes unfamiliar (or novel) nature of the decision task requires analytic strategies to generate good solutions. Therefore, decisions about precision strike capabilities are best made with a mixture of intuitive and analytic thought, a mode of thinking known as quasirationality.     

Examining the Relationships Between the Justice Facets and Turnover Intent: The Mediating Roles of Overall Justice and Psychological Strain

We examined how interpersonal justice from coworkers, the traditional justice facets (i.e., distributive, procedural, interpersonal, informational), and overall justice perceptions relate to employee psychological strain and turnover intentions in Canadian Armed Forces personnel. Specifically, we hypothesized that overall justice would mediate the relationships between the justice facets (including coworker justice) and strain, and strain would mediate the relationship between overall justice and turnover intent. We used a cross-sectional correlational design with personnel from 2 military units (total N = 218) as our sample. A 2-step structural equation modeling technique was used to evaluate our hypotheses. Support for our hypotheses was obtained with 1 exception: informational justice did not predict overall justice judgments. Our results suggest that employees’ reactions to individual justice events and different sources of justice exert their effects on strain and turnover intent indirectly through their impact on a global evaluation of justice in their work environment.     

Initial Validation of the U.S. Army Global Assessment Tool

The U.S. Army developed the Global Assessment Tool (GAT) to monitor psychosocial fitness and well-being among soldiers and provide a means to objectively gauge the success of newly implemented resilience training programs. Despite its widespread use (taken over 5.2 million times) and stated utility for program evaluation, there is relatively little published evidence regarding the GAT’s reliability and validity. We used exploratory structural equation modeling (ESEM) with 4 random samples of soldiers (n = 10,000 each) to examine the factorial validity and reliability of the GAT. An 11-factor solution (Self-Management, Positive Affect, Meaning, Work Engagement, Organizational Trust, Loneliness, Negative Cognitions, Hostility, Negative Emotions, Depressive Symptoms, and Emotion-Focused Coping), with 4 additional factors assessing character strengths (Intellect, Warmth, Civic Strengths, and Temperance), fit well and replicated in a second random sample. A higher order, 2-factor model using composites scores and positing positive and negative psychosocial competencies also fit well. Tests of measurement invariance using a third random sample reinforced consistent measurement properties across gender, age, and rank, with the exception of character strengths, which produced different factor structures for males and females. Further validity tests using a fourth random sample underscored a modicum of divergence among the resilience factors and convergence among the character strengths factors. We conclude with recommendations for enhancing and refining the GAT and discuss the GAT’s utility as a reliable, multidimensional psychosocial assessment that can be used to evaluate the efficacy of military resilience training programs.
