Post-decision consolidation in large group decision-making

Decision-makers tend to change the psychological attractiveness of decision alternatives in favor of their own preferred alternative after the decision is made. In two experiments, the present research examined whether such decision consolidation occurs also among individual group members in a large group decision-making situation. High-school students were presented with a decision scenario on an important issue in their school. The final decision was made by in-group authority, out-group authority or by majority after a ballot voting. Results showed that individual members of large groups changed the attractiveness of their preferred alternative from a pre- to a post-decision phase, that these consolidation effects increased when decisions were made by in-group members, and when participants identified strongly with their school. Implications of the findings for understanding of group behavior and subgroup relations are discussed.     

Patterns of Ethnic Intolerance in Europe

This paper examines the patterns of ethnic intolerance in European societies based on data from the 1999/2000 wave of the European Values Survey. We analyze the differences in intolerance targeted toward Muslims, Jews, immigrants, Gypsies, and persons of different race, using modernisation theory and ??competition for scarce resource?? theories as our point of departure. Furthermore, we focus on the differences in the levels of intolerance in Western Europe, Eastern Europe, and Turkey. The present paper builds on previous empirical research, especially findings of recent multilevel analyses. Our larger and more extensive data material enables us to introduce two important improvements in this line of research. Theoretically, we are able to test if there are differences in the patterns of intolerance targeted toward specific minority groups. Methodologically, the number of countries in our data material is much larger, allowing us to apply multilevel models in a more statistically appropriate setting. Our results show that Gypsies stand out as an ethnic group particularly exposed to intolerance. The level of intolerance is lowest in Western Europe and highest in Turkey. In addition, the level of intolerance against Jews is particularly high in Turkey.     

Relationships Between Cognitive and Behavioral Measures of Executive Function in Children With Brain Disease

This study addressed the clinical and construct validity of the Behavior Rating Inventory of Executive Function. (BRIEF: Gioia, Isquith, Guy, & Kenworthy, 2000), a questionnaire designed to tap behavioral aspects of executive functions in children. BRIEF profiles in early treated phenylketonuria (PKU; n = 44), early treated hydrocephalus (n = 45), frontal focal lesions (n = 20) and controls (n = 80) were examined. Clinical validity was supported through significant between-group comparisons, especially between the frontal focal lesion group and other groups. To examine construct validity, raw scores on cognitive executive function measures including the Contingency Naming Test (CNT), Rey Complex Figure (RCF), Tower of London (TOL), and Controlled Oral Word Association Test (COWAT), were correlated with BRIEF scale scores. Few significant correlations were found, indicating cognitive and behavioral measures appear to tap different constructs within the executive function domain. A dissociation was found between behavioral and cognitive impairments in the frontal as opposed to PKU and hydrocephalus groups. This is discussed in relation to underlying pathology, the cognitive measures used, and possible limitations in the BRIEF's usefulness for measuring behavioral executive dysfunction in groups only mildly affected by neurological compromise.     

Memories of real-life decisions

Three studies investigated decision makers’ memory representations of choice alternatives in most important real-life decisions. In Study 1, each participant recalled the most important decision that she or he had ever made and rated to what degree a number of characteristics could describe the decisions. In Study 2, the participants were asked to think about an important decision that they had made during the last 7–10 days. In Study 3, the memory representations of decisions of a group of action-oriented participants were compared with those of a group of state-oriented participants (Kuhl, 1983). Characteristics related to standard decision theory, like consequences, values, and likelihood, had high ratings of applicability as well as affect/feeling. When testing the applicability of a circumplex model, the fuzzy-trace theory of memory, and differences between state- and action-oriented decision makers, we found (1) that there was no support for the circumplex model of emotions. Instead, an important decision problem was characterised by both positive and negative affect/emotion and thus, a bipolar mapping was found inadequate; (2) that a comparison of abstract and concrete aspects showed that the abstract characteristics scored higher, thereby supporting the fuzzy-trace theory; and (3) that the prediction that action-oriented participants would score higher than state-oriented participants on the characteristic of activity was not supported. However, state-oriented decision makers rated passivity higher than action-oriented decision makers for the important decision of leaving a partner. State-oriented decision makers used perceptual/cognitive scenario representations to a greater extent than action-oriented participants. Finally, it was stressed that in the development of decision theories it is essential to find theoretical representations as close as possible to how decision makers themselves represent the decisions. The method used in this contribution is focused on the role of memory in decision making and gives further insights into how important real-life decisions are represented by different decision makers.     

Evaluation of the school-based smoking-prevention program "BE smokeFREE"

This article examines the impact of the school-based smoking-prevention program "BE smokeFREE" on adolescent smoking. A national representative sample of 99 schools (195 classes, 4,441 students) was used when the intervention started in November 1994. Schools were allocated to one of four groups: a comparison group (A) and three intervention groups (B, C, and D). Group B received the most comprehensive intervention. A baseline (autumn 1994) and three follow-up data collections (1995, 1996, and 1997) were conducted. There were no significant differences in smoking habits among the four groups at baseline. The smoking habits in the group that was involved in the most comprehensive intervention (group B) changed more favourably than those of students in the comparison schools over the three follow-up data collections. At the third follow-up, the proportion of students smoking weekly or more in the comparison group was 29.2%, compared with 19.6% in the model intervention group. The two less comprehensive interventions (no teacher in-service courses in group C, and no involvement of parents in group D) appeared to be less effective than the model intervention. Multilevel multiple logistic regression analyses, comparing changes in smoking habits between students in group B with those among students in the comparison schools, confirm the conclusion that the comprehensive intervention was the most effective. This school-based intervention, based on a social influence approach, proved to be effective at reducing smoking rates among participants.     

Differentiation and consolidation theory of human decision making: A frame of reference for the study of pre- and post-decision processes

Differentiation and Consolidation Theory of decision making models human decision making as an active process in which one alternative is gradually differentiated from other available alternatives. The theory is based on the assumption that it is not sufficient to choose the best alternative, but that a decision involves the selection and creation of a candidate that is sufficiently superior for a decision. This is achieved in differentiation processes which are wholistic, structural or process related. To exemplify, structural differentiation includes both facts and attractiveness restructuring. Following a decision, the theory predicts consolidation processes which work in favor of the chosen alternative. Both differentiation and consolidation are driven by the fact that through experience with the impredictability of the future, a decision maker has learned to prepare for threats against the chosen alternatives. The further this alternative has been differentiated and consolidated, the less the risk of post-decision ambiguity, regret or decision reversal. The study is concluded with references to othee decision theories some of which are viewed as subtheories of Differentiation and Consolidation Theory.     

Are we all less risky and more skillful than our fellow drivers?

In this study subjects were asked about their competence as drivers in relation to a group of drivers. The results showed that a majority of subjects regarded themselves as more skillful and less risky than the average driver in each group respectively. This result was compared with similar recent findings in other fields. Finally, the consequences for planning and risk taking of seeing oneself as more competent than others were discussed briefly.
