Diversity’s harvest: Interactions of diversity sources and communication technology on creative group performance

Our research is based on arguments that three different diversity sources in groups – agreeableness, openness, and ethnicity – might simultaneously possess separation properties that result in social categorization and variety properties that provide non-redundant and value-adding information resources. To help understand how these diversity sources interact with the additive and reductive features of communication technology to impact group creativity, we designed two studies involving computer mediation, nominal group technique, and face-to-face (control) communication. Our findings suggest that agreeableness, openness, and ethic diversity possess both negative separation and positive variety properties. Whereas the separation properties of all three diversity sources, as well as the variety properties of openness diversity, are evident in newly-formed groups, the variety properties of agreeableness and ethnic diversity are only manifest in mature groups. Finally, the additive and reductive features of communication technology interact with all three diversity sources to impact creative group performance in different ways.     

Multiple citizenship and naturalization: An evaluation of German and Dutch policies

In many countries the trend has been toward greater acceptance of multiple citizenship and more naturalizations of immigrants. This article analyses and compares developments in Germany and the Netherlands. Central questions are how policies toward dual citizenship have developed and to what extent these policies have influenced naturalization rates. The far-reaching toleration of dual citizenship in the Netherlands in the 1990s resulted in high naturalization rates. However, there were large differences between immigrant groups. Similar differences are found in Germany. Multiple citizenship carries little importance for European Union (EU) citizens, who feel no need to naturalize, and for refugees, who have no desire to retain the citizenship of their country of origin.     

Socratic Proofs for Quantifiers

First-order logic is formalized by means of tools taken from the logic of questions. A calculus of questions which is a counterpart of the Pure Calculus of Quantifiers is presented. A direct proof of completeness of the calculus is given. *Research for this paper was supported by The Foundation for Polish Science (both authors), and indirectly (in the case of the first author) by a bilateral exchange project funded by the Ministry of the Flemish Community (project BIL 01/80) and the State Committee for Scientific Research, Poland.     

A Transtheoretical Approach to Case Formulation

In answer to the need for a comprehensive, systematic, yet flexible case formulation method, the present article describes the Causal Analysis and Synthesis of Events (CASE) system, a transtheoretical case formulation method. This method of functional case formulation is useful in terms of explicating the problem and identifying potential areas for intervention when dealing with clinical problems of both an intrapersonal and interpersonal nature. Further, this formulation method may improve communication between the therapist and the client during case conceptualization and facilitate dialogue between therapists of different theoretical orientations. This paper describes the case formulation method and includes an example incorporating this case formulation technique for a young man with social phobia.     

Understanding Public Attitudes Toward Tobacco Harm Reduction: The Role of Attitude Structure1

The present research examines whether and to what extent the underlying structure of attitudes toward harm reduction and specific reduced‐exposure products contributes to an understanding of public attitudes toward harm reduction. Past research has focused on the extent to which some attitude objects are primarily affective or cognitive. Using survey data from a 5‐state Upper Midwest sample, we tested the relevance of 4 pertinent properties of attitudes for predicting overall attitudes toward tobacco harm reduction: affective and cognitive bases of attitudes; knowledge; experience with smoking and reduced‐harm products; and affective/cognitive consistency. We found that feelings about harm reduction are most predictive of overall attitudes toward harm reduction and specific reduced‐harm products. Theoretical and policy implications are discussed.     

Selection in Teams: An Exploration of the Teamwork Knowledge,Skills, and Ability Test

In 1994, Stevens and Campion introduced the Teamwork Knowledge, Skills, and Ability test (teamwork KSA test) for selecting employees for team–based organizations. Using experimental data from 57 ad hoc student teams (N = 227), we examined this test's relationship with both the behavior of the assigned leader in a team and the behavior of the other team members, respectively. We found that the teamwork KSA test successfully predicted individual team member behavior as indexed by external raters (r= .31) and peers (r= .34) such that higher scores on the teamwork KSA test related to greater individual effectiveness within the team. The teamwork KSA test was unrelated to the behavior of the assigned leader in the teams studied. Self–efficacy for teamwork was not related to individual behavior in teams, nor did it moderate the relationship between the teamwork KSA test and individual performance in teams. Limitations as well as directions for future research in team selection are discussed.     

Assessment of the Effectiveness of Genetic Counseling by Telephone Compared to a Clinic Visit

Maternal serum screening, also known as the triple screen, is used during pregnancy to assess the risk of carrying a fetus with specific chromosome abnormalities or open spina bifida. All women in British Columbia who screen positive are eligible for genetic counseling and are offered amniocentesis. The purpose of this study is to determine what differences (if any) exist in patients' understanding and/or anxiety when genetic counseling for a positive triple screen is conducted in person versus over the telephone. Each patient who participated was given the choice of having genetic counseling in person or over the telephone, this after a randomized design failed to elicit any participants. Using a written postcounseling questionnaire, each patient was assessed for her understanding of the information presented in the session, and her anxiety regarding her risk. In this small pilot study, no large differences were detected in patients' understanding or anxiety when genetic counseling was conducted by telephone versus in person.     

Life Satisfaction is not a Balanced Estimator of the Good Life: Evidence from Reaction Time Measures and Self-Reported Emotions

A widespread belief in happiness research is that measures of life satisfaction capture the variety of an individual’s experiences along a single favorable—unfavorable dimension. The current article points to a possible violation of this assumption. With a combination of data and theory it argues that life satisfaction is not a balanced reflection of subjective experiences because the evaluation that drives judgments of life satisfaction is tilted towards pleasure and away from engagement. We postulate that feelings of pleasure are overrated in statements of life satisfaction, whereas feelings of engagement are underrepresented. Feelings of engagement and interest are further supposed to be indicators of personal growth. Measures of personal growth and life satisfaction should thus be unrelated. Empirical evidence for our model is provided by self-report and reaction time data from a Norwegian convenience sample (N = 30). Detection latencies for pleasant stimuli correlated significantly with life satisfaction but not with measures of personal growth. Life satisfaction correlated significantly with pleasant experiences, but not with engagement. Personal growth correlated significantly with feelings of engagement. Life satisfaction and personal growth were uncorrelated.     

Do tests of executive functioning predict ability to downregulate emotions spontaneously and when instructed to suppress?

Behavioral regulation is a hallmark feature of executive functioning (EF). The present study investigated whether commonly used neuropsychological test measures of EF (i.e., working memory, Stroop, trail making, and verbal fluency) were related to ability to downregulate emotion both spontaneously and when instructed to suppress emotional expressions. To ensure a wide range of EF, 24 frontotemporal lobar degeneration patients, 7 Alzheimer's patients, and 17 neurologically normal controls participated. Participants were exposed to an acoustic startle stimulus (single aversive noise burst) under three conditions: (1) unwarned, (2) warned with no instructions (to measure spontaneous emotion downregulation), and (3) warned with instructions to suppress (to measure instructed emotion downregulation). Results indicated that higher verbal fluency scores were related to greater emotion regulation (operationalized as reduction in body movement and emotional facial behavior when warned of the impending startle) in both regulation conditions. No relationships were found between emotion regulation in these conditions and the other EF measures. We conclude that, of four commonly used measures of EF, verbal fluency best indexes the complex processes of monitoring, evaluation, and control necessary for successful emotion regulation, both spontaneously and following instructions to suppress.
