Information sampling and group decision making: the effects of an advocacy decision procedure and task experience

Group discussions tend to focus on information that was previously known by all members (shared information) rather than information known by only 1 member (unshared information). If the shared information implies a suboptimal alternative, this sampling bias is associated with inaccurate group decisions. The present study examines the impact of 2 factors on information exchange and decision quality: (a) an advocacy group decision procedure versus unstructured discussion and (b) task experience. Results show that advocacy groups discussed both more shared and unshared information than free-discussion groups. Further, with increasing experience, more unshared information was mentioned in advocacy groups. In contrast, there was no such increase in unstructured discussions. Yet advocacy groups did not significantly improve their decision quality with experience.     

A meta-analysis on the correlation between the implicit association test and explicit self-report measures

Theoretically, low correlations between implicit and explicit measures can be due to (a) motivational biases in explicit self reports, (b) lack of introspective access to implicitly assessed representations, (c) factors influencing the retrieval of information from memory, (d) method-related characteristics of the two measures, or (e) complete independence of the underlying constructs. The present study addressed these questions from a meta-analytic perspective, investigating the correlation between the Implicit Association Test (IAT) and explicit self-report measures. Based on a sample of 126 studies, the mean effect size was .24, with approximately half of the variability across correlations attributable to moderator variables. Correlations systematically increased as a function of (a) increasing spontaneity of self-reports and (b) increasing conceptual correspondence between measures. These results suggest that implicit and explicit measures are generally related but that higher order inferences and lack of conceptual correspondence can reduce the influence of automatic associations on explicit self-reports.     

Character Disposition and Behavior Type: Influences of Valence on Preschool Children's Social Judgments

The authors studied the influences of valence information on preschool children's (n = 47) moral (good or bad), liking (liked or disliked by a friend), and consequence-of-behavior (reward or punishment) judgments. The authors presented 8 scenarios describing the behavior valence, positive valence (help, share), negative valence (verbal insult, physical aggression), and disposition valence (nice or mean) of characters in social interaction with a friend. Overall, character disposition and behavior valence significantly influenced children's judgments. Moral, liking, and consequence-of-behavior judgments varied significantly by character disposition for both positive behavior scenarios. In contrast, there were fewer significant findings as a function of character disposition for negative behavior scenarios, suggesting that the negative behavior cue somewhat diminished the effect of character disposition on children's judgments. The authors discuss preschool students’ coordination of information about valence of behavior and character disposition and the students’ reluctance to judge that misbehavior warrants punitive consequence.     

Strength-Based Positive Interventions: Further Evidence for Their Potential in Enhancing Well-Being and Alleviating Depression

The impact of nine strengths-based positive interventions on well-being and depression was examined in an Internet-based randomized placebo-controlled study. The aims of the study were to: (1) replicate findings on the effectiveness of the gratitude visit, three good things, and using character strengths interventions; (2) test variants of interventions (noting three good things for 2 weeks; combining the gratitude visit and three good things interventions; and noting three funny things for a week); and (3) test the effectiveness of the counting kindness, gift of time, and another door opens-interventions in an online setting. A total of 622 adults subjected themselves to one of the nine interventions or to a placebo control exercise (early memories) and thereafter estimated their degrees of happiness and depression at five times (pre- and post-test, 1-, 3-, and 6 months follow-up). Eight of the nine interventions increased happiness; depression was decreased in all groups, including the placebo control group. We conclude that happiness can be enhanced through some “strengths-based” interventions. Possible mechanisms for the effectiveness of the interventions are discussed.     

Interference within hands: Retrieval-induced forgetting of left and right hand movements

We examined retrieval-induced forgetting of motor sequences that were categorized by the effectors (left or right hand) involved in their execution. This left–right categorization was independent from input locations or input devices. In addition, the acquired motor sequences were arbitrarily assigned to left and right. Participants learned twelve sequential joystick movements as responses to letter stimuli. Half of the sequences pertained to the left, half to the right hand. Subsequent retrieval-practice of half the items of one hand induced forgetting for the non-retrieved rest of the items of that hand in a final recall test. This finding demonstrates that the hands were used to organize the memory storage of motor sequences in a way that gave rise to later interference between commonly stored items, that is, linked to the same hand.     

A robust classic

In the present research, we argue for the robustness of illusory correlations (ICs, Hamilton & Gifford, 1976) regarding two boundary conditions suggested in previous research. First, we argue that ICs are maintained under extended experience. Using simulations, we derive conflicting predictions. Whereas noise-based accounts predict ICs to be maintained (Fielder, 2000; Smith, 1991), a prominent account based on discrepancy-reducing feedback learning predicts ICs to disappear (Van Rooy et al., 2003). An experiment involving 320 observations with majority and minority members supports the claim that ICs are maintained. Second, we show that actively using the stereotype to make predictions that are met with reward and punishment does not eliminate the bias. In addition, participants' operant reactions afford a novel online measure of ICs. In sum, our findings highlight the robustness of ICs that can be explained as a result of unbiased but noisy learning.     

Pragmatic Pluralism: Arendt,Cosmopolitanism, and Religion

Pragmatic pluralism denotes a particular approach to problems of international human rights and protections that departs from conventional cosmopolitan approaches. Pragmatic pluralism argues for situated and localized forms of cooperation between state and non-state actors, particularly religious groups and organizations, that may not share the secular, juridical understandings of rights, persons, and obligations common to contemporary cosmopolitan theory. A resource for the development of such a model of pragmatic pluralism can be found in the work of Hannah Arendt. Arendt's early dissertation "Love and Saint Augustine" affords a model of religious community and obligation that can be read productively alongside her later political writings. The possibilities inherent in a cooperative reading of these two parts of her work can be illustrated in relation to an issue of particular concern to cosmopolitan theorists: the international refugee crisis.
