The legal basis for the Danish committee on scientific dishonesty

The author, a High Court Judge, has chaired the Danish Committee on Scientific Dishonesty (DCSD) since its establishment in 1992. The Committee has worked in the health sector, but from 1999 the scope has been broadened to cover all fields of science. The article describes how the work is organised and the experiences gained. It is stressed, that the difficulty in connection with scientific dishonesty is, first and foremost, to organise a system suitable for investigating cases effectively, professionally, and with proper respect to the fundamental legal rights of the parties involved. The Committee has also spent much effort in determining what can be termed scientific dishonesty and what falls outside this category but which may, nevertheless, be characterised as breaching of good scientific practice. It is emphasised that these rules are not arbitrarily established by the Committee, but formulated in accordance with norms general accepted by opinion leaders in the scientific community. An carlier version of this paper was presented at a symposium, Scientific Misconduct. An International Perspective, organised by The Medical University of Warsaw, 16 November, 1998. The article is based on more comprehensive articles by the same author in DCSD’s Annual Reports for 1993 and 1995.     

Analysis of the decision-making process leading to appendectomy: a grounded theory study

The aim was to develop a theoretical understanding of the decision-making process leading to appendectomy. A qualitative interview study was performed in the grounded theory tradition using the constant comparative method to analyze data. The study setting was one county hospital and two local hospitals in Sweden, where 11 surgeons and 15 surgical nurses were interviewed. A model was developed which suggests that surgeons' decision making regarding appendectomy is formed by the interplay between their medical assessment of the patient's condition and a set of contextual characteristics. The latter consist of three interacting factors: (1) organizational conditions, (2) the professional actors' individual characteristics and interaction, and (3) the personal characteristics of the patient and his or her family or relatives. In case the outcome of medical assessment is ambiguous, the risk evaluation and final decision will be influenced by an interaction of the contextual characteristics. It was concluded that, compared to existing, rational models of decision making, the model presented identified potentially important contextual characteristics and an outline on when they come into play.     

The cognitive substrate of subjective probability

The prominent cognitive theories of probability judgment were primarily developed to explain cognitive biases rather than to account for the cognitive processes in probability judgment. In this article the authors compare 3 major theories of the processes and representations in probability judgment: the representativeness heuristic, implemented as prototype similarity, relative likelihood, or evidential support accumulation (ESAM; D. J. Koehler, C. M. White, & R. Grondin, 2003); cue-based relative frequency; and exemplar memory, implemented by probabilities from exemplars (PROBEX; P. Juslin & M. Persson, 2002). Three experiments with different task structures consistently demonstrate that exemplar memory is the best account of the data whereas the results are inconsistent with extant formulations of the representativeness heuristic and cue-based relative frequency.     

Using artificial life to teach evolutionary biology

This paper presents a pilot study on the use of artificial life software in an educational setting. Two groups of high school students received a standard lesson in evolutionary biology followed by a software session. The experimental group used the suite of artificial life software presented in this paper; the control group used a commercial multimedia hypertext. At the end of the software session both groups were asked to fill in a simple multiple-choice questionnaire testing the students knowledge of various aspects of evolutionary biology. The results show that the group using the artificial life software performed significantly better than the control group. We argue that the experimental group may learn more effectively because the artificial life makes it possible for students to perform experiments, a possibility not available to the control group.

Is there a Scandinavian psychology? A bibliometric note on the publication profiles of Denmark,Finland, Norway,and Sweden

This note presents a quantitative bibliometric analysis based on information obtained from the PsycINFO database concerning publication patterns in different subfields of Scandinavian psychology for the years 1984 to 1997. A cluster analysis shows that the publication profiles of the Scandinavian countries are more similar to each other than to both the profile of the USA and a norm profile based on all countries except the USA and Scandinavia. The main differences are that the relative proportions of articles dealing with psychological disorders are higher and the relative proportions of articles dealing with educational psychology are lower for Scandinavia than for the rest of the world. Within the Scandinavian countries, Finland and Sweden form one cluster with higher relative proportions of psychophysiological articles, and Denmark and Norway form one cluster with higher relative proportions of articles dealing with psychological disorders.     

The face you recognize may not be the one you saw: memory conjunction errors in individuals with or without learning disability

Memory conjunction errors, that is, when a combination of two previously presented stimuli is erroneously recognized as previously having been seen, were investigated in a face recognition task with drawings and photographs in 23 individuals with learning disability, and 18 chronologically age-matched controls without learning disability. Compared to the controls, individuals with learning disability committed significantly more conjunction errors, feature errors (one old and one new component), but had lower correct recognition, when the results were adjusted for different guessing levels. A dual-processing approach gained more support than a binding approach. However, neither of the approaches could explain all of the results. The results of the learning disability group were only partly related to non-verbal intelligence.     

A Danish version of the Sensation Seeking Scale and its relation to a broad spectrum of behavioral and psychological characteristics

The primary purpose of the present study was to evaluate the internal consistency and construct validity of the Danish translation of Zuckerman's Sensation Seeking Scale (SSS). The secondary aim was to extend the range of psychological variables and behaviors that have been related to sensation seeking. The sample consisted of 691 subjects (363 males and 328 females) with a mean age of 31.7 years. The internal consistency of the scales was evaluated by coefficient alpha and intercorrelations among the five scales derived from the SSS were computed. Information on other variables was collected through standardized tests as well as questionnaires and interviews developed especially for this study. The results showed that the Danish SSS is a psychometrically sound instrument and revealed the relationship between sensation seeking and a broad spectrum of psychological traits and behaviors: socioeconomic status, academic achievement, intelligence, personality, smoking, alcohol and drug use, sexuality, driving and public transportation violations, and leisure time activities. Thus, this study confirmed and expanded the findings of many previous studies, while the results supported the validity of the Danish SSS and corroborated the usefulness of the concept of sensation seeking.     

Scope of linguistic influence: does a classifier system alter object concepts?

Whether and to what extent conceptual structure is universal is of great importance for understanding the nature of human concepts. Two major factors that might affect concepts are language and culture. The authors investigated whether these 2 factors affect concepts of everyday objects in any significant ways. Specifically, they tested (a) whether the system of grammatical categorization by classifiers influenced the conceptual structure of speakers of classifier languages, and (b) whether Westerners organized object concepts around taxonomic relations whereas Easterners organized them around thematic relations, as proposed by R. E. Nisbett (2003). The relative importance of 3 types of relations--taxonomic, thematic, and classifier--for Chinese and German speakers was tested using a range of tasks, including categorization, similarity judgment, property induction, and fast-speed word-picture matching. Some support for linguistic relativity as well as for the cultural-specific cognition proposal was found in some tasks, but these effects were miniscule compared with the importance of taxonomic and thematic relations for both language-culture groups. The authors conclude that the global structure of everyday object concepts is strikingly similar across different cultures and languages.
