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.

     

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.     

The foundation of the institute for experimental psychology at Leipzig University

Summary During the 1979–80 academic year psychologists from all over the world will celebrate the centennial of the Institute for Experimental Psychology at Leipzig University, established by Wilhelm Wundt during the winter of 1879–80. First, this paper will present the historical context in which the laboratory method of research instruction developed in nineteenth-century Germany. Next, Wundt's extensive experience with laboratory research before coming to Leipzig will be described. Finally, the origin, development, and organization of Wundt's laboratory will be chronicled, beginning with his call to Leipzig. The implications of Wundt's achievement for modern psychology will be discussed. Emphasis is placed on the use of archival materials, documents, and eyewitness accounts.A slightly modified version of this paper was presented as an Invited Centennial Lecture at the Annual Meeting of the American Psychological Association in New York on September 4, 1979The preparation of this article was supported by a research award from the Dr. W.W. Kaempfer, the Dean of the College of Arts and Sciences, University of South Alabama, Mobile, Alabama, USA
