Freges Erläuterung des Urteils

According to Frege the notion of judgement cannot be defined, but must be explicated by referring to natural language. Frege uses a subjective and an objective notion of judgement: on the one hand a judgement is an inner mental process, on the other hand judging is explained as advancing from the thought to the truth-value. The subjective notion of judgement logically depends on the objective conception of a judgement, but nevertheless remains indispensable. To clarify the objective notion of judgement, the relation of thought and truth must be explicated by using Frege's theory of sense and reference. Only an intersubjective and action-guiding knowledge of the way in which the truth-value of a sentence is determined can make it possible to advance from the thought and the understanding of a sentence to the acknowledgement of its truth. Since by this advance a sentence receives a cognitive value, Frege's theory of sense and reference makes a contribution not only to semantics but also to epistemology.     

Interpersonal determinants of attitude change following counterattitudinal behavior

In a test of predictions derived from an identity-analytic model of self-presentational behavior, individuals who privately endorsed positive or negative attitudes about sexual behavior were asked to deliver a prosexuality speech while alone, while watched by observers, or while being watched by observers who questioned the morality of the subject’s actions. Subsequent attitude measures indicated that the subjects who initially adopted negative attitudes justified their behavior by expressing more favorable attitudes about sexuality, but only when no audience witnessed their speech. When an audience was present, these individuals emphasized their lack of choice. In contrast, subjects who privately endorsed positive attitudes publicly expressed less favorable attitudes when their morality was challenged by the observers. These findings suggest that attitude change following counterattitudinal behavior (a) stems from private image-maintenance needs as well as public self-presentational concerns, and (b) is sometimes designed to secure an image of morality as well as an image of consistency.     

On the assessment of genetic technology: Reaching ethical judgments in the light of modern technology

The “Model for Reaching Ethical Judgments in the context of Modern Technologies — the Case of Genetic Technology”, which is presented here, has arisen from the project “Ethical Criteria bearing upon Decisions taken in the field of Biotechnology”. This project has been pursued since 1991 in the Zentrum für interdisziplinäre Technikforschung (ZIT) of the Technical University of Darmstadt, with the purpose of examining decision-making in selected activities involving the production of transgenic plants that have a useful application. The model is the basis of an outline for interviews to investigate how far decisions concerning the development of such plants with genetic techniques take ethical criteria into account. It was necessary to design this new model because other models for reaching judgments of this kind were not conceptually suited for concrete application. This model represents a problem related approach and combines methodological with substantive typology. In this it differs from comparable models for reaching ethical judgments.     

Ästhetische Befriedigung und Unbestimmtheitsreduktion

Zusammenfassung Vpn mußten unter standardisierten Bedingungen zweidimensionale Farbmuster herstellen, die ihrer Meinung nach ästhetisch maximal befriedigend, bzw. maximal unbefriedigend waren. Die beiden Gruppen von Bildern wurden untersucht, wobei sich eine Gruppe von ästhetisch befriedigenden und zwei Gruppen von ästhetisch unbefriedigenden Bildern zeigten. Eine weitere Analyse ergab, daß sich die ästhetisch befriedigenden Bilder von den ästhetisch unbefriedigenden statistisch darin unterscheiden, daß bei den ästhetisch befriedigenden Bildern die Farbelemente in hohem Maße zum Aufbau komplizierter und tiefer Hierarchien von Zeichen höherer Ordnung verwendet wurden, wohingegen bei den ästhetisch unbefriedigenden Mustern übergeordnete Konfigurationen entweder nur in einfacher Form und flachen Hierarchien auftreten (1. Gruppe) oder Zeichen höherer Ordnung gar nicht vorhanden sind (2. Gruppe). Aufgrund der empirischen Ergebnisse wird die Hypothese aufgestellt, daß ästhetische Befriedigung auf Unbestimmtheitsreduktion gegen Widerstand zurückgeführt werden kann. In einem nachfolgenden Experiment wurde diese Hypothese geprüft und bestätigt.

Aesthetical appreciation and the reduction of uncertainty

Summary Subjects were asked to construct colored pictures which they considered to be aesthetically maximally pleasing or unpleasing. These two groups of pictures were analyzed and it was found that the aesthetically pleasing pictures showed a statistically significant increase in the number of higher order configurations of color elements and a greater hierarchical organization of such configurations. Furthermore, the higher order configurations of the aesthetically pleasing pictures were of a more complicated structure than the higher order configurations of the aesthetically unpleasing pictures. Considering these results, the hypothesis was raised that aesthetical appreciation may be based on the reduction of uncertainty against the resistance of a complicated system of ordering relations within a stimulus. This hypothesis was tested and verified in a subsequent experiment.

     

Achievement motivation in college women revisited: Implications for women,men, and the gathering of coconuts

An attempt was made to replicate the findings of French and Lesser (1964) within one university on the effects of value-appropriate arousal conditions on achievement motivation scores and motivation performance relationships in women. The findings of this study do not uphold those previously reported. There were no significant differences on either achievement motivation scores or task performance under value-appropriate versus -inappropriate arousal conditions. In the present study there were two innovations — performance criteria were extended to include academic performance, and scoring procedures were developed to give equal weight to achievement imagery in areas defined as traditionally feminine. The principle findings concern the importance of the scoring procedures. Intellectual (classic) N Ach does not relate to value orientation, task performance, or grade point average. Women's Role N Ach, however, is significantly related to task performance and to grade point average. This motivation-performance relationship exists despite differences in value orientation among women. It is suggested that when scoring procedures allow subjects, male or female, to express achievement strivings in areas of value to them, then performance may be morc sensitive to motivational variables.This article is based on research supported by Grant 1 RO1 HD-02403-01 from the National Institute of Mental Health to Lynette K.

Primate learning tasks reveal strong impairments in patients with presenile or senile dementia of the Alzheimer type

Eight subjects with the likely diagnosis of presenile or senile dementia of the Alzheimer type were tested on two frequently used primate learning tasks: a concurrent object discrimination task and a delayed non-match-to-sample task. In addition, various tests for cognitive, mnemonic, perceptual, and language functions were applied. The results suggest a severe decline of the Alzheimer subjects in all measures when compared with 10 control subjects matched for age, gender, and education. The two animal learning tasks revealed strong impairments, thus demonstrating a high sensitivity for the detection and assessment of human amnesic disorders. Implications of these findings for human neuropsychological, and especially comparative neuropsychological, research are discussed.
