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.

The categorical perception of colors and facial expressions: The effect of verbal interference

A series of five experiments examined the categorical perception previously found for color and facial expressions. Using a two-alternative forced-choice recognition memory paradigm, it was found that verbal interference selectively removed the defining feature of categorical perception. Under verbal interference, there was no longer the greater accuracy normally observed for cross-category judgments relative to within-category judgments. The advantage for cross-category comparisons in memory appeared to derive from verbal coding both at encoding and at storage. It thus appears that while both visual and verbal codes may be employed in the recognition memory for colors and facial expressions, subjects only made use of verbal coding when demonstrating categorical perception.     

The development of color categories in two languages: a longitudinal study

This study unites investigations into the linguistic relativity of color categories with research on children's category acquisition. Naming, comprehension, and memory for colors were tracked in 2 populations over a 3-year period. Children from a seminomadic equatorial African culture, whose language contains 5 color terms, were compared with a group of English children. Despite differences in visual environment, language, and education, they showed similar patterns of term acquisition. Both groups acquired color vocabulary slowly and with great individual variation. Those knowing no color terms made recognition errors based on perceptual distance, and the influence of naming on memory increased with age. An initial perceptually driven color continuum appears to be progressively organized into sets appropriate to each culture and language.     

Differences in performance of young and old monkeys on a visuospatial memory task

Two groups of stumptailed macaques (Macaca arctoides) were compared in terms of performance on a visuospatial working memory task involving repeated presentations of an array of 15 doors, each of which concealed one food reward at the start of a session. Rewards obtained by the subject were not replaced. Errors were defined as responses to doors previously pushed open during the session. Both groups generally obtained all rewards and showed improved performance across sessions, but old monkeys consistently made more errors than young ones, especially in the latter half of a given session. Further, old monkeys were less diverse in the errors they made, indicating different response strategies by the two groups.     

Cultural and Historical Aspects of Eating Disorders

A review of cultural and historical accounts of anorexia nervosa indicates that this disorder is found primarily in Westernized societies during periods of relative affluence and greater social opportunities for women. Some hypotheses regarding the vulnerability to eating disorders are proposed to the basis of these data.     

The Mental Representations of Faces and Houses: Issues Concerning Parts and Wholes

We explore the integration of facial features and house parts to form holistic representations of complete objects. In Experiments 1, 2, and 3, we test for evidence of the holistic representation of houses and faces. We do so by testing for a complete over part probe advantage (CPA) in 2AFC recognition and matching tasks. We present evidence consistent with holistic features being represented for both types of stimuli. In Experiments 4 and 5, we examine further theeffect with faces. Experiment 4 shows thatfacial features used in the matching task contribute differentially to CPAs across varying probe delays but with a similar pattern to that found in the recognition task (Experiment 1). Experiment5 shows thatCPAs are mandatory and cannot be removed by precueing with the probe type or the name of the feature to be probed.     

A Further Study of the Validity of Human Form Drawings In Personality Evaluation

Three studies describe the development, psychometric properties, and potential utility of a new self-report measure, the Circumplex Scales of Interpersonal Values (CSIV). The CSIV was designed to complement other interpersonal circumplex measures that assess interpersonal behavior by efficiently assessing a comprehensive set of agentic and communal values. The eight 8-item scales of the CSIV were shown to have good internal consistency and test-retest reliability and a circumplex structure. The CSIV showed convergent and discriminant validity with measures of interpersonal traits (the Bem Sex Role Inventory; Bem, 1974), interpersonal problems (the Inventory of Interpersonal Problems-Circumplex; Horowitz, 2000), implicit interpersonal motives (the Thematic Apperception Test; see Atkinson, 1958), and interpersonal goals (the Interpersonal Goals Inventory; Dryer &; Horowitz, 1997). Finally, the locations of the MCMI-III (Millon, 1994) personality disorder scales on the CSIV circumplex generally mirrored the locations of personality disorders on other interpersonal circumplex measures.
