Does Handedness Determine Which Hand Leads in a Bimanual Task?

Right- and left-handers (n = 16 in each group) were tested on a bimanual circle task that required drawing either in the same direction (parallel) or in a mirror symmetrical coordination mode with the two hands. The authors' primary purposes were to examine the effect of circle direction on within-hand and between-hands variables and to determine whether the relation between hand lead and coordination mode (parallel or mirror symmetrical) differs for left- and right-handers. A strong relation was found between lead hand and movement condition, which depended on the direction of the movements and whether the task was parallel or mirror symmetrical. The pattern of results was similar for left-and right-handers on parallel tasks, but group differences were found with respect to mirror symmetrical tasks. At odds with the general claim that the dominant hand leads, the present results indicated that hand dominance does not generally determine which hand leads.     

Hempel’s logic of confirmation

This paper presents a new analysis of C.G. Hempel’s conditions of adequacy for any relation of confirmation [Hempel C. G. (1945). Aspects of scientific explanation and other essays in the philosophy of science. New York: The Free Press, pp. 3–51.], differing from the one Carnap gave in §87 of his [1962. Logical foundations of probability (2nd ed.). Chicago: University of Chicago Press.]. Hempel, it is argued, felt the need for two concepts of confirmation: one aiming at true hypotheses and another aiming at informative hypotheses. However, he also realized that these two concepts are conflicting, and he gave up the concept of confirmation aiming at informative hypotheses. I then show that one can have Hempel’s cake and eat it too. There is a logic that takes into account both of these two conflicting aspects. According to this logic, a sentence H is an acceptable hypothesis for evidence E if and only if H is both sufficiently plausible given E and sufficiently informative about E. Finally, the logic sheds new light on Carnap’s analysis.     

Does the counter-cultural character of new age persist? Investigating social and political attitudes of new age followers

From its beginnings in the 1960s up to the present, the New Age movement has undergone considerable change. Originally, it was a counter-cultural movement, interacting with other counter-cultural movements of that time, such as the ecology, hippie, and commune movements. During the last decades, spiritual and esoteric methods have been popularised and commercialised by an expanding market of literature and workshops. This has made New Age a socially accepted phenomenon and it has thus lost much of its anti-modernist and culture-critical character. In this article, I will show by means of quantitative empirical analyses that in spite of the transformations, the affinity between New Age activism and culture-critical attitudes persists to a certain degree. This is particularly the case for persons aiming at self-perfection by means of spiritual exercises and alternative health methods. Among persons who are primarily interested in esoteric methods, such as astrology and Tarot cards, hedonistic and authoritarian attitudes are, however, more widespread.     

Transzendentalpragmatik und Diskursethik. Elemente und Perspektiven der Apelschen Diskursphilosophie

Transcendental Pragmatics and Discourse Ethics. Elements and Perspectives of Apel's Discourse-Philosophy. The author follows Apel's intellectual biography and shows the conception of a critique of meaning qua ‘reflection upon the discourse within the discourse’ to be the centre of Apel's language-pragmatic ‘Transformation of Philosophy’ (Frankfurt a.M. 1973). Beginning with an explication of the situation of a speaker/thinker, especially of the situation of a philosophising speaker/thinker, Apel reconstructs a two fold apriori of communication: Every thought is situated within the context of a particular, historically evolved, community of language and interaction. At the same time, however, the validity-claims of thoughts transcend the context of their origin towards an unlimited community of argumentation. On the basis of the first apriori Apel criticises the methodical solipsism as well as the objectivism of modern philosophy and theory of science. Drawing upon the second apriori he develops a universalist critique of meaning of relativism and contextualism. In the sixties and seventies Apel worked out a differentiated theory of the – more or less – communicatively cognizing humanities and set it apart from the theory of the causal-explanatory natural sciences, thus challenging the objectivism of a Theory of Unified Science. Building upon this work Transcendental Pragmatics, as developed by Apel and others, sets philosophy primarily two tasks: firstly, a (fallible) internal reconstruction of argumentative discourse as the (logical) situation of speech and thought which seeks to elucidate the conditions of the meaningfulness, i. e. the presuppositions, of discourse. These presuppositions comprise, thus Apel with Habermas, the four validity-claims to intelligibility, sincerety/credibility, truth and normative rightness/legitimacy. Their moral content consists, thus Apel, not only in the recognition of the equality of all beings capable of discursive reasoning but also in their recognition of a co-responsibility for the realizability of discourses and of responsibility. The author argues that the existence of a co-responsibility of this kind is indisputable because the discursive claims to validity are intertwined with a set of ‘primordial promises of dialogue’. Only with the elucidation and explication of these promises can the reconstruction of the internal conditions of discourse be completed.The second task of a pragmatics of argumentation isthe strict resp. actual reflection of the thinker upon the presuppositions of the discourse in which he currently engages. This reflection has a Socratic character and can only be done in the form of discussion and debate (‘Auseinandersetzungen’, Apel, Frankfurt a.M. 1998) with critics of the reconstruction. In this context, the author proposes a method of Socratic reflection upon the presuppositions of dialogue which suspends the usual, theoretically oriented, attitude of the scientist and the philosopher in favour of an actual reflective attitude. Within a dialogue with a sceptic who doubts one of the results of the internal reconstruction of dialogical presuppositions, say X, it is tested whether his doubt as to the unrestricted validity of X can be understood as a sincere contribution to the current dialogue or whether this particular sceptical thesis does not make sense, because it is incompatible with the role of a sincere participant of argumentation which, after all, the sceptic cannot refuse to claim for himself.Finally the author explains Apel's characterization of the tension between “Discourse and Responsibility” (Frankfurt a.M. 1988). In the course of discussions with Max Weber, Lawrence Kohlberg, Hans Jonas et al., Apel formulates and justifies an ethics of responsibility and gives an affirmative answer to the crucial question of whether the fulfilment of the moral obligations connected with the recognition of co-responsibility can be demanded within the non-dialogical circumstances of social reality. Apel's answer employs the idea of counter-strategies which are morally legitimate in virtue of their being worthy of argumentative consensus.

Parents' role in adolescents' decision on a college major: A weekly diary study

This study examined 39 adolescents during their transition to university. In standardized weekly diaries over several weeks (M = 8.13) adolescents reported on engagement in career exploration (in-breadth and in-depth self and environmental exploration), their parents' transition-related involvement (frequency of conversations, support, and interference), and their satisfaction with how the transition progressed. The results showed that exploration largely fluctuated across weeks, whereas parent involvement was more stable. Family members' engagement varied according to the phase of the application process the adolescent was involved in. The more adolescents explored during a given week, the more they talked to their parents, and the more supportive parents were. Associations between interference and exploration differed by type of exploration. Both exploration and support contributed to higher satisfaction.     

Peer Victimization,Self-Concept,and Grades: The Mediating Role of Self-Concept

This study examined the relations between specific forms of peer victimization, math self-concept, and math grades of 740 students. Results showed that, in boys, all forms of victimization did not affect grades, while in girls, a highly perceived social exclusion impacted grades. In boys, a highly perceived humiliation negatively affected self-concept, whereas a highly perceived social exclusion positively affected self-concept. Boys’ self-concept mediated the relations between social exclusion and grades as well as between humiliation and grades. In girls, a highly perceived happy slapping positively affected self-concept, and self-concept mediated the relation between a highly perceived happy slapping and grades.     

The Role of Core Self-Evaluations in Explaining Depression and Work Engagement among Managers

The present study tests interaction effects between working characteristics and core self-evaluations (CSE) among managers. Based on the job demands-resources model, we outline that CSE is a buffer for negative health-related consequences initialized by facing high job demands. Moreover, we hypothesize that CSE is positively linked to job resources and motivation. A sample of 282 managers participated in the study in Germany. Results based on hierarchical regression analysis confirmed that high CSE significantly weakens the positive relationship between high job demands and depression among managers. Furthermore, a significant interaction effect between job resources and CSE on work engagement was found. Therefore, the study reveals that it seems unlikely that CSE biases how managers appraise the environment since individuals low in CSE benefitted more from favorable working conditions than those high in CSE. Suggestions for future research as well as implications for theory and practice are derived.
