Ein Argumentationsspiel um das Münchhausen-Trilemma

By means of a strategic game the present paper tries to answer the question of whether the so-called trilemma of Münchhausen (H. Albert)as it stands is able to perform the twofold task of both refuting the methodology of foundationalismand of getting us thereby nearer to the methodology of critical rationalism.The formal reconstruction of the argument provides us with four possible versions which however can only be called trilemmas in a wider sense of this term. Moreover, a test shows three of them to be invalid. The subsequent discussion of the only valid one makes clear that in order to save the truth of its premisses as far as possible the latter have to be modified in a way that brings us still farther away from the original trilemma of Münchhausen. But even then it may be doubted whether the remains of the argument can fulfil the above-mentioned twofold task.     

Selecting a best multiattribute alternative with partial information about attribute weights

Use of approximate weights would greatly simplify decision analysis under certainty since detailed weight elicitation could be avoided. This paper examines the degree to which rank order information about weights can be used to identify a best alternative, or falling uniqueness prescribes an easily implemented rule for selecting a ‘best’ alternative. The prescribed rule uses as weights the centroid of the feasible region defined by the rank order information. In conjunction with the rule, the value of the rank order information can be determined using an ‘expected gain from weight precision’ (EGWP) measure, analogous to ‘expected value of perfect information’ in decision analysis under uncertainty.     

Everyday memory performance across the life span: effects of age and noncognitive individual differences.

Gerontologists have long been concerned with the impact of individual-difference factors on memory. This study used a large sample (N = 2,495) of adult volunteers aged 18 to 90 years to determine if a set of individual-difference variables--vocabulary, education, depression, gender, marital status, and employment status--mediates the effects of aging on a wide range of laboratory-analogue tests of everyday memory. The data indicated that age was consistently the most significant predictor of memory performance, followed by vocabulary and gender. Vocabulary totally mediated age effects on a prose memory measure, and partial mediation of aging effects--primarily by vocabulary and gender--was observed on 5 other memory tests. These data suggest that when health samples of volunteers serve as research subjects, these individual differences can affect some memory test scores, but age remains the best overall predictor of memory performance.

Differences that suggest female investment in,and male distance from,children

A factorial between subjects experiment was conducted with sex of respondent, level of success, sex of stimulus parent, and sex of stimulus child as the independent variables. Two hundred seventy-two undergraduates without parenting experience constituted the sample. The attributions made to explain parenting success/failure and the ratings made both of the child and the parent on the same 60 personality item were the dependent variables. Female respondents were not only especially success-oriented, but evidenced a view of parenting emphasizing deliberation and skill, whereas their male counterparts were comparatively more inclined to explain failure in terms of it being the child's fault and to overstate a child's meanness.This investigation was completed on the first author's NIMH traineeship (5 T01 MH-14473) for doctoral study. The authors are appreciative of the contributions of Professors Donn Byrne, Kay Deaux, and William Martin to the development of this study.
