Safeguarding good scientific practice: New institutional approaches in Germany

After summarising three recent case histories of alleged scientific misconduct in Germany, the efforts of the Deutsche Forschungsgemeinschaft (German Research Council) and the Hochschulrektorenkonferenz (German Rectors' Conference) to promote academic and procedural safeguards in favour of professional self-regulation in science and scholarship are described in outline.     

Software for generating psychological experiments

This review compares four software packages for generating and running psychological computer experiments. It aims to inform researchers' decisions about which software to choose for their lab. Four widely used general purpose commercial packages available for the Windows platform are considered: DirectRT, E-Prime, Inquisit, and SuperLab. An overview of each package is given, and the implementation of two test experiments is described. Packages are evaluated with regard to the amount of complexity reduction they provide for the task of programming an experiment and the variety of experimental designs they can accommodate.     

Contextualist Approaches to Epistemology: Problems and Prospects

In this paper we survey some main arguments for and against epistemological contextualism. We distinguish and discuss various kinds of contextualism, such as attributer contextualism (the most influential version of which is semantic, conversational, or radical contextualism); indexicalism; proto-contextualism; Wittgensteinian contextualism; subject, inferential, or issue contextualism; epistemic contextualism; and virtue contextualism. Starting with a sketch of Dretskes Relevant Alternatives Theory and Nozicks Tracking Account of Knowledge, we reconstruct the history of various forms of contextualism and the ways contextualists try to handle some notorious epistemological quandaries, especially skepticism and the lottery paradox. Then we outline the most important problems that contextualist theories face, and give overviews of their criticisms and defenses as developed in this issue.     

Internistische Psychosomatik

Zusammenfassung Die psychische Komorbidität internistischer Patienten im Sinne einer ICD-Diagnose des Kapitels F beträgt mehr als 35%: Neurotische, besonders somatoforme, Schmerz-, affektive Störungen und Suchterkrankungen sind häufig. Die Liegedauer ist bei psychischer Komorbidität deutlich erhöht. Es benötigen 5% der internistischen Patienten ein psychosomatisches Konsil. Neue, komplexe Behandlungsstrategien, wie Transplantationen, Kardioverter-Defibrillatoren, Medikamentenpumpen, erfordern häufig spezifische psychosoziale Interventionen. Ältere Patienten haben Erkrankungen, die zunehmend chronifizieren und komplexer werden. Damit werden Lebensqualität und psychische Komorbidität zu zentralen Outcomevariablen der Volkskrankheiten. Das zweite große Aufgabenfeld internistischer Psychosomatik ist die Untersuchung und die Behandlung psychosomatischer Patienten im engeren Sinne (Essstörungen, Schmerz- und somatoforme Störungen), weil internistische Diagnostik und Therapie erforderlich oder die Motivation der Patienten primär somatisch ist. Organisationsmodelle reichen von Konsil-/Liaisondiensten bis zu integrierten psychosomatischen Abteilungen oder Fachabteilungen an Allgemeinkrankenhäusern. Aussichtsreiche Forschungsstrategien werden neben der Erforschung psychosomatischer Mechanismen in der Entwicklung pragmatischer Behandlungsprogramme, ihrer Überprüfung in klinischen Studien und der Versorgungsforschung gesehen. Darüber hinaus sollte eine Intensivierung nationaler und internationaler Forschungsnetze erfolgen, wenn immer möglich unter Beteiligung anderer Disziplinen, um auch im Bereich der Forschung konkurrenzfähig zu bleiben.Herrn Prof. Dr. Ernst Richard Petzold zum 65.

The Reflecting Team approach: convergent results of two exploratory studies

This paper presents results of two exploratory investigations concerning the effectiveness of the Reflecting Team (RT) approach, conducted in Vienna and in Gottingen. Fifty-nine families/couples participated in the RT approach in the two outpatient settings. Follow-up reports from 35 families – obtained on average 15 months after closure – indicated that this model may be considered effective as well as efficient: two thirds of all clients (who made up a heterogeneous group with regard to diagnostic criteria and stage of development of the identified patient) reported symptom improvement, and about 80% said they were very satisfied; these results were obtained with a fairly small number of sessions.     

An exact and optimal standardized person test for assessing consistency with the rasch model

The Rasch model predicts that an individual's ability level is invariant over subtests of the total test, and thus, all subtests measure the same latent trait. A person test of this invariance hypothesis is discussed that is uniformly most powerful and standardized in the sense that the conditional distribution of the test statistic, given a particular level of ability, does not depend on the absolute value of the examinee's ability parameter. The test can be routinely performed by applying a computer program designed by and obtainable from the author. Finally, a suboptimal test is derived that is extremely easy to use, and an overall group test of the invariance hypothesis discussed. All tests considered do not rely on asymptotic approximations; hence, they may be applied when the test is of only moderate length and the group of examinees is small.     

Prebirth marital interactions and postbirth marital development

A considerable body of research supports the general statement that “couples who before the birth of their first child are characterized by positive mutuality, partner autonomy, and the ability to confront problems and regulate negative affect are responsive to the needs of their infants, promote their autonomy and have more secure and autonomous children, as seen throughout the first 4 years of life” (Heinicke, 1995). The implications for infant mental health are profound, but more needs to be known about what specific prebirth marital qualities interact with and anticipate postbirth marital and child functioning. This is a study of the association between the nature of the couple's prebirth interaction and their marital adaptation during the first 2 years of the child's life. Linking pre- and postbirth marital functioning, the frequency of negative affect and off-task scores, as well as the inability to resolve their issues in the prebirth marital interaction, anticipated a declining or consistently low postbirth marital adaptation.

Promoting perspective coordination by dilemma discussion. The effectiveness of classroom group discussion on interpersonal negotiation strategies of 12-year-old students

Promoting social competence and social cognition is an important aim of education and socialization. According to theories of social cognitive and moral development, social cognition may be promoted by adolescent peer interaction. In this study, social cognition is theoretically conceptualized by the interpersonal negotiation strategies model of Selman which distinguishes levels of perspective coordination and steps of information processing (identification of a problem, generating negotiation strategies, selection of a strategy, evaluation). In a pre-post control group design this study investigated whether dilemma discussions among peers lead to higher individual levels of perspective coordination compared to an individualistic condition. Members of the discussion-condition exhibited higher gain scores in perspective coordination compared to the control group regarding the information processing steps generating strategies and strategy selection. In order to analyze verbal interaction in the discussion groups, an integrative coding schedule was developed. In addition, trait-like argumentative motives of the participants were assessed. The results of multilevel analyses suggest that progress in posttest-perspective coordination is mediated by the groups consensual solution of the dilemma as well as by an explanation-oriented discussion style, but only if the latter is accompanied by a trait-like subject- and consensus-oriented argumentative motive. Theoretical and practical conclusions are drawn.
