Universality and Cultural Diversity in Moral Reasoning and Judgment.

Many theories have shaped the concept of morality and its development by anchoring it in the realm of the social systems and values of each culture. This review discusses the current formulation of moral theories that attempt to explain cultural factors affecting moral judgment and reasoning. It aims to survey key criticisms that emerged in the past decades. In both cases, we highlight examples of cultural differences in morality, to show that there are cultural patterns of moral cognition in Westerners' individualistic culture and Easterners' collectivist culture. It suggests a paradigmatic change in this field by proposing pluralist "moralities" thought to be universal and rooted in the human evolutionary past. Notwithstanding, cultures vary substantially in their promotion and transmission of a multitude of moral reasonings and judgments. Depending on history, religious beliefs, social ecology, and institutional regulations (e.g., kinship structure and economic markets), each society develops a moral system emphasizing several moral orientations. This variability raises questions for normative theories of morality from a cross-cultural perspective. Consequently, we shed light on future descriptive work on morality to identify the cultural characteristics likely to impact the expression or development of reasoning, justification, argumentation, and moral judgment in Westerners' individualistic culture and Easterners' collectivist culture.

Motor planning between 4 and 7 years of age: changes linked to executive functions.

In the present study, we adopted the conceptual frameworks of Miyake et al. (2000) (organization of executive functions) and Sergeant (2000) (linking executive function to motor behaviour) to assess developmental changes in executive functions and motor behaviour, using a planning task with a sample of 4-7-years old children. More precisely, the aim of the study was to characterize the development of motor response planning between the ages of 4 and 7 as a measure of the integration of multiple executive function processes, namely inhibition, shifting and working memory, and to gain insight into the concurrent developmental contributions of these processes. Participants were divided into two groups: group 1 was composed of 24 children aged 4-5 years and group 2 was composed of 20 children aged 6-7 years. Each participant took tests for shifting, inhibition, working memory and motor planning (the egg-planning task). Our results suggest that the egg-planning task requires the inhibition of a pre-potent but inappropriate response, and to a lesser extent the manipulation of working memory strategies. These results are discussed in relation to the development of each executive function component.

Bullying, sleep/wake patterns and subjective sleep disorders: findings from a cross-sectional survey.

The aim of this study was to explore: (a) sleep patterns and disorders possibly associated with adolescent bullying profiles (pure bully, pure victim, bully/victim and neutral) and (b) the effect of sleep on psychosocial problems (externalized and internalized) related to bullying. The sample consisted of 1422 students aged 10-18 (mean = 14.3, SD = 2.7; 57% male) from five socioeconomically diverse schools in France. Bullying profiles were obtained using the revised Bully-Victim Questionnaire. Subjective sleep disorders were assessed using the Athens Insomnia Scale. School-week and weekend sleep/wake patterns were recorded. Internalizing problems were investigated using a Perceived Social Disintegration Scale and a Psychological Distress Scale. Externalizing behaviors were assessed using a General Aggressiveness Scale and an Antisocial Behavior Scale. These questionnaires were administered during individual interviews at school. After controlling for effects of gender and age, victims of bullying showed significantly more subjective sleep disturbances than the pure-bully or neutral groups (p < 0.001). Bullies' sleep schedules were more irregular (p < 0.001 for bedtime irregularity and p<0.01 for wake-up time irregularity) and their sleep duration was shorter than their schoolmates (p < 0.001 for the school week and p < 0.05 for the weekend). There was an effect of sleep on psychosocial problems related to bullying, and our results indicate that sleep has a moderating effect on aggression in bullies (p < 0.001). This would suggest a higher vulnerability of bullies to sleep deprivation. These results show differences in sleep problems and patterns in school-bullying profiles. Findings of this study open up new perspectives for understanding and preventing bullying in schools, with implications for research and clinical applications.

Aging and categorization: could relevant pieces of information reduce older persons' inhibitory deficit?

The goal of this study was to reduce the inhibitory deficit on the elderly by creating "optimizing conditions" in a categorization task. It was hypothesized that increasing the number of relevant pieces of information would reduce the difficulty associated with processing irrelevant information on a categorization task, since the number of relevant solutions to solve the problem would increase, while the total number of pieces of information to be processed would remain the same. This hypothesis was tested on 27 young adults and 30 elderly people using a task requiring the matching of a stimulus figure to one of the two response figures having one or more attributes in common with the stimulus. In line with previous findings, the results indicated an age-related inhibitory decline. However, consistent with the hypothesis, as the number of relevant attributes increased, the performance of elderly people improved and response times decreased, supporting the notion of latent cognitive resources.
