Effects of visual-field inversions on the reverse-perspective illusion

The 'reverse-perspective' illusion entails the apparent motion of a stationary scene painted in relief and containing misleading depth cues. We have found that, using prism goggles to induce horizontal or vertical visual-field reversals, the illusory motion is greatly reduced or eliminated in the direction for which the goggles reverse the visual field. We argue that the illusion is a consequence of the observer's inability to reconcile changes in visual information due to body movement with implicit knowledge concerning anticipated changes. As such, the reverse-perspective illusion may prove to be useful in the study of the integration of linear perspective and motion parallax information.     

Truth,Sentential Non-Compositionalit,and Ontology

The paper attempts to clarify some fundamental aspects of an explanationof the concept of truth which is neither deflationary nor substantive.The main aspect examined in detail concerns the ontological dimension of truth, the mind/language-world connection traditionally associated with the concept of truth. It is claimed that it does not make sense to defend or reject a relatedness of truth to the ontological dimension so long as the kind of presupposed or envisaged ontology is not made explicit and critically examined. In particular, it is shown that generally an objectual ontology is – often only implicitly – presupposed, i.e., an ontology admitting objects (substances), properties, relations, sometimes also facts, events, and the like. The paper demonstrates that such an ontology derives from the Principle of Semantic Sentential Compositionality and that this principle should be rejected. It introduces instead the Principle of Semantic Sentential Contextuality (or Context Principle) as the semantic basis of a new ontology, an ontology of primary states of affairs. After sketching such an ontology, it is shown that the relatedness of truth to the ontological dimension becomes intelligible.     

basic objectives of dialogue logic in historical perspective

The extensive research in logic conducted by using concepts and methods of game theory as documented in this collection of papers, allows to see dialogue logic in a number of new perspectives. This situation may gain further clarity by looking back to the inception of dialogue logic in the late fifties and early sixties.     

Revisiting the university front

The article argues that the most important trends in the recent metamorphosis of higher education, especially of university teaching and research, cannot be understood without placing them in the context of general developments in political life. Both processes reveal alarming features and there is a link between them. In recent decades a religion has established its dominance in the public policy field. Its dogmas are called “liberalization”, “economic man”, “individual preference”, “the free market”, “competition” and “efficiency”. The consequences of the progressive imposition of this doctrine on the universities—including on the relation between teaching and research—are well documented but not always well understood. It is argued that the “commercialization” of higher education and research means in reality their hyper-bureaucratization, via the imposition of so-called evaluation, assessment and accreditation schemes, the latest avatars of the managerialist ideology. Might the final result be the disintegration of the university as an institution?     

On the association of interparental conflict with developing behavioral inhibition and behavior problems in early childhood.

Associations between interparental conflict and the development of temperament characteristics have seldom been addressed; moreover, studies on the impact of interparental conflict on developing behavior problems in infancy and early childhood are relatively rare. The authors therefore aimed to contribute to the study of these issues. A sample of 64 families was investigated longitudinally. At the infant age of 4 months, negative emotionality was measured with a laboratory routine. When infants were 4, 8, and 12 months old, maternal sensitivity was assessed during home observations, and interparental conflict was measured by means of questionnaires. When infants were 30 months old, behavioral inhibition was measured in 2 laboratory fear episodes, and behavior problems were assessed with a structured clinical interview of the primary caregiver. Interparental conflict and infant negative emotionality were significantly and independently associated with subsequent behavioral inhibition. The association of interparental conflict with behavior problems was moderated by infant negative emotionality. Infants high in negative emotionality developed more serious behavior problems when exposed to high interparental conflict, whereas the association was not significant in infants low in negative emotionality.     

Terrorist threat and employees' perceived ability to cope with organizational change

This study investigated the impact of the perceived threat of terrorism on employees' ability to cope with organizational change as well as potentially underlying psychological mechanisms related to work satisfaction and initiative. Three days after the 2006 thwarted terrorist attacks in the United Kingdom, participants were reminded of terrorist threat (by pictures of terrorist attacks) reported lower levels in their ability to cope with organizational change, as well as lower levels of work satisfaction, than did participants who were not reminded of terrorist threat. Three months later, the same terror salience manipulation had no differential effect on these variables. Mediation analyses revealed that work satisfaction mediated the impact of terror salience on employees' ability to cope with organizational change.     

Personality Traits (“Big Five”) and the Propensity to Political Protest: Alternative Models

In a representative panel study, citizens of Leipzig (East Germany) were interviewed in 1993 and 1996 about their incentives for and participation in political protest activities. Conscientiousness, neuroticism, agreeableness, openness to experience, and extraversion (the Big Five) were measured with 16 bipolar adjectives. The present report supplements a previous work of the authors that drew on the theories of rational choice and collective action and conceived of incentives as proximal causes and personality dispositions as distant causes of political protest. Based on structural equation modelling (SEM), the present article deals with the respondents' recurrent reports on protest incentives and protest acts as indicators of the latent construct protest propensity that is according to the predictions directly influenced by openness to experience (O+), agreeableness (A?), neuroticism (N?), and reciprocity orientation (N*E+) with 35% explained variance.     

Topografie der Jugenddelinquenz

The article shows that the registered juvenile delinquency has decreased in recent years. Serious violent crime partially exists, but this is only a small part of the overall juvenile delinquency. Forms of appearance of these violent crimes are outlined. With the help of a dark field study it is illustrated that there is a great variety of delinquency among young people. There are young people showing mostly law-abiding behavior, infrequent offenders and a group with a significant burden of crimes.
