Social categorization and intergroup behaviour

The aim of the studies was to assess the effefcs of social categorization on intergroup behaviour when, in the intergroup situation, neither calculations of individual interest nor previously existing attitudes of hostility could have been said to have determined discriminative behaviour against an outgroup. These conditions were satisfied in the experimental design. In the first series of experiments, it was found that the subjects favoured their own group in the distribution of real rewards and penalities in a situation in which nothing but the variable of fairly irrelevant classification distinguished between the ingroup and the outgroup. In the second series of experiments it was found that: 1) maximum joint profit independent of group membership did not affect significantly the manner in which the subjects divided real pecuniary rewards; 2) maximum profit for own group did affect the distribution of rewards; 3) the clearest effect on the distribution of rewards was due to the subjects' attempt to achieve a maximum difference between the ingroup and the outgroup even at the price of sacrificing other ‘objective’ advantages. The design and the results of the study are theoretically discussed within the framework of social norms and expectations and particularly in relation to a ‘generic’ norm of outgroup behaviour prevalent in some societies.     

THE ROLE OF SELF-ESTEEM IN COMPETITIVE CHOICE BEHAVIOR1

Le rôle de L'estime de soi dans les choix compétitifs — Un programme transnational de recherche sur les déterminants des processus de décision s'est concentré dans une première phase sur la relation entre L'estime de soi et le comportement compétitif dans un jeu de type « Dilemme du prisonnier ». Des étudiants américains, chez lesquels une grande estime de soi avait été induite, firent davantage de choix compétitifs que les sujets chez lesquels on avait induit une faible estime de soi. Une des deux expériences avec des étudiants français a reproduit les mêmes résultats, alors que des expériences avec des sujets italiens ont produit des résultats inverses. Différentes interprétations théoriques des résultats sont proposées et critiquées.     

Letting and making death happen,withholding and withdrawing life-support: Morally irrelevant distinctions

The author argues that there is no morally relevant distinction between letting and making death happen, and between withholding and withdrawing life-support. There is a discussion of possible adverse consequences in believing that there are moral distinctions. And then he shows that acknowledging the absence of such a distinction does not necessarily imply any endorsement of active euthanasia.     

Development of visuomanual tracking in 5- to 9-year-old boys

Visuomanual sinusoidal tracking is investigated in 5- to 9-year-old children. The proportion of successful performances steadily increases with age, but adult proficiency is never attained even by those who can perform the task. Moreover, the progress in proficiency—as measured by systems analysis techniques—is not monotonic and suggests the presence of distinct stages in the development of visuomotor coordination. Qualitative analysis of unsuccessful performance demonstrates that failures cannot be ascribed only to insufficient motor coordination and emphasizes the role of cognitive and representational factors even in such a simple task.     

The application of multiple factorial methods to the study of motor abilities

A battery of thirteen tests of motor abilities are analyzed by means of the Thurstone factor methods. Interpretations of the nature of the six factors extracted are offered, with reservations. The high degree of specificity of motor abilities results in very narrow group factors.     

Challenging the transcendental position: the holism of experience

Taking the problem of perception and illusion as a leading clue, this article presents a new phenomenological approach to perception and the world: “holism of experience.” It challenges not only Husserl’s transcendentalism, but also what remains of it in Heidegger’s early thought, on the grounds that it is committed to the skeptical inference: “Since we can always doubt any perception, we can always doubt perception as a whole.” The rejection of such an implicit inference leads to a relational paradigm of Being-in-the-World that differs from Heidegger’s on many points.     

Équivalence échelle composite – échelle globale dans la mesure de la satisfaction au travail

We measured work satisfaction within the same sample (n=12) using two different methods : the one-item-scale global measure and the facet-scales composite measure. Results showed that the global scale is not equivalent to summated facet scales. This results can be explained by the fact that composite measures don’t take into account the proper weight of each facet in the computation of general work satisfaction. Considering limits presented by mixed measures in order to show up this weights, we advocate the development of a work satisfaction composite measure that integrates the measure of the importance allocated to each facet of work in the computation of general work satisfaction.
