Attributions restore consistency in bargaining with liked/disliked partners

The experiment deals with the impact of self-esteem and liking for the partner on the attribution of agreement and deadlock in bargaining. Fifty-eight male and 70 female students played the Harsanyi-Selten bargaining game with incomplete information eight times, allegedly each time with a randomly selected partner. In fact in four games a computer program simulated the partner. Combining an experimental variation of liking (liking—disliking), own costs (low, high), partner costs (low, high) the experiment followed a 2×2×2 repeated measures design. As predicted by a path model from balance theory (a) failure (deadlock) was attributed more to the partner and less to self than success (agreement), (b) success was attributed more to the liked than the disliked partner, whereas failure was attributed more to the disliked than the liked partner.     

Genetic Counseling Practices in Germany: A Comparison Between East German and West German Geneticists

As part of an international study of ethics and genetics, we present a comparison between survey responses of 43 East German and 212 West German geneticists to anonymous questionnaires. Both groups indicated that the experience of the Third Reich has impacted the genetics profession in Germany today. East German geneticists reported more directive counseling practices after prenatal diagnosis for 10 of 26 conditions than those from West Germany. When asked to give their personal opinions about pregnancy termination, East Germans were more accepting of abortion than their West German colleagues for 7 of 24 fetal indications. In addition, there were significant differences between the two sample groups for 8 questions on the perception of disability and society. Discussions with German geneticists suggest that, while both groups were affected by Germany's experience of Nazism, different abortion laws, political systems, and ideas about the doctor-patient relationship in former East and West Germany may account for discrepancies in reported genetic counseling practices and in attitudes toward abortion and disability.     

Formal paraphasias: A single case study

A case study is reported of an aphasic patient, RB, who showed frequent form-related whole-word substitutions in oral naming, writing to dictation, and reading aloud. In both written language tasks, the abstractness of the targets influenced the number of formal errors. In oral naming, a high proportion of formal paraphasias was related to the intended words in both form and meaning. A comparison between targets and formal paraphasias indicated a high agreement both in word class, number of syllables, stress pattern, and in basic (stressed) vowels. The agreement in consonants (including word-initial consonants), however, was low. It is argued that RB's formal substitutions are not caused solely by errors of lexical selection but that semantic, lexical, and segmental factors contribute to the error outcome.     

Pseudo maximum likelihood estimation and a test for misspecification in mean and covariance structure models

Using the theory of pseudo maximum likelihood estimation the asymptotic covariance matrix of maximum likelihood estimates for mean and covariance structure models is given for the case where the variables are not multivariate normal. This asymptotic covariance matrix is consistently estimated without the computation of the empirical fourth order moment matrix. Using quasi-maximum likelihood theory a Hausman misspecification test is developed. This test is sensitive to misspecification caused by errors that are correlated with the independent variables. This misspecification cannot be detected by the test statistics currently used in covariance structure analysis.For helpful comments on a previous draft of the paper we are indebted to Kenneth A.

E-Teaching-Panacea or Crisis?

Human beings need communication. During the development of mankind, a multitude of communication technologies have been invented and used. Some of them had a dramatic impact on society in general and on the way scientific knowledge was disseminated. In this article we discuss some of the effects of each of these changes to teaching as a way of disseminating scientific knowledge. We discuss some of the potential effects caused by the new revolution of communication due to the World Wide Web and the potential of ubiquitous computing. We discuss the evolution of communication technology followed by a discussion of the achievements of each technology. Next, the effects of these achievements on teaching are discussed. Finally, we set these considerations into a broader context and discuss the effects on two important parameters: lead time of the teacher and verifiability of the teacher's claims.
