COMPARAISON INTERLINGUISTIQUE DE MATÉRIEL VERBAL PROPRE A L'APPRENTISSAGE DE CONCEPT1

Inter-language comparison of verbal material for the study of concept formation. — A list of 215 French words, which were translation equivalents of the words in Underwood and Richardson's (1956) published list, were presented to 119 French students from which single, restricted to sense impression associates were obtained. A systematic inter-language comparison is established and differences between French and English speaking subjects discussed. The piocedure adopted by Mednick and Halpern (1962) to study the ease of concept attainment as a function of Associative Rank has been applied to French subjects. A replication using a direct translation of the English nouns shows no difference between concepts at Associative Rank 1 and 2. It appears indeed from norms of the French group that the concepts selected are balanced not only with respect to Dominance Level but also with respect to Mean Associative Rank. But further experiment, with a material established according to the norms of the French list of associates, shows a very significant difference in the mean number of trials taken to solve each concept. It thus strengthened the assumption of homogeneity of associative response hierarchies in a given language community.     

The measurement of principled morality by the Kohlberg Moral Dilemma Questionnaire

The four stages preceding the postconventional level in the Kohlberg (1958, 1971, 1976) system of moral development are described as involving moral judgments that conform to external conditions of punishment, reward, social expectation, and conformity to the law. No special level of self-control seems necessary to behave in keeping with these conditions of external reinforcement. In contrast, the two stages of postconventional (principled) mortality involve defiance of majority opinion and defiance of the law--actions that would seem to require greater self-control. This study was concerned with whether postconventional moral reasoning, as measured by the Kohlberg Moral Dilemma Questionnaire (MDQ), can be associated with higher self-control. If so, prediction of principled moral behavior from the MDQ would be based not only on postconventional moral reasoning but bolstered by the necessary level of self-control as well. College students who came the closest to postconventional moral reasoning showed better self-control than college students who were more conventional or preconventional in their moral judgments. These results support the validity of the MDQ for predicting principled moral behavior.

Right–left approach and reaching arm movements of 4-month infants in free and constrained conditions

Recent theories on the evolution of language (e.g. Corballis, 2009) emphazise the interest of early manifestations of manual laterality and manual specialization in human infants. In the present study, left- and right-hand movements towards a midline object were observed in 24 infants aged 4 months in a constrained condition, in which the hands were maintained closed, and in a free condition. A left-hand dominance for approach movements without contact with the object, and a right-hand dominance for reaching movements with object contact was observed in the free condition. In the constrained condition reaching movements of the right hand decreased dramatically. These results are interpreted as strong evidence of manual specialization in 4-month olds, with approach movements having a localization role and reaching movements announcing future right-hand dominance for prehension and object manipulation.     

The link between school climate and violence in school: A meta-analytic review

There has been significant interest in whether and how school climate and violent behavior are meaningfully related. The present meta-analysis reviewed studies reporting a relationship between school climate and school violence in order to summarize the total effect and the direction of these research findings. Database consultation and literature hand searching yielded 145 articles which were reviewed by two experts. Studies were included if they reported a statistical effect size of the relationship between school climate and school violence. Exclusion criteria were unclear operationalization of the principal variables, research findings from multiple publications, studies using multi-level analysis and qualitative studies. The meta-analysis included 36 independent studies (N = 113,778) with correlations ranging from ? .02 to ? .53. Using a random-effects model a moderate mean effect size of r = ? .26, CI [? 30, ? 21] was found. Statistical findings indicated significant heterogeneity and a large range of variance between studies. Meta-regressions analyzed different potential moderators as relevant factors of heterogeneity, but none of these factors could be identified as a moderator. Due to the large variance between the studies, it remains difficult to draw final conclusions. Nevertheless, the moderate effect size underlines the role of environmental aspects for school violence intervention.
