SITUATIONS SOCIALES À POTENTIEL CONFLICTUEL ET CARACTÉRISTIQUES SOCIO-COGNITIVES D'ENFANTS AGRESSIFS ET REJETÉS*

Twenty aggressive and rejected children (boys and girls), twenty socially competent and popular children, and twenty children having average social skills - all of which were first and second graders attending regular school - participated in this study. All were presented on videotape with nine typical peer-conflict situations. Each child was asked about the way that he/she felt, and the way that he/she would resolve each problem situation. In addition, each child had to specify what he/she thought to be the offender's intentions in each problem situation. Several points differentiated first grade from second grade subjects. However, aggressive, socially skilled and average subjects distinguished themselves on only a few items. Differences relating to subject's sex were also scarce. Data support the view that aggressive children know as well as other children how to appropriately resolve interpersonal conflict situations. However, they do not use this knowledge because of impulsivity control problems, an inability to correctly identify others' intentions or a lack of motivation.     

Genetic and Rearing Environmental Influences on Adult Personality: An Analysis of Adopted Twins Reared Apart

ABSTRACT We report a genetic and environmental analysis of California Psychological Inventory (CPI) scale scores gathered on a sample of 45 sets of monozygotic twins reared apart (MZA) and 26 sets of dizygotic twins reared apart (DZA) Analysis of twin intraclass correlations and the results of models fit to the twin data demonstrate that the heritability of most scales and five factors of the CPI is about 50 When compared to results from studies of adult MZ and DZ twins reared together few of the scales demonstrate any common family environmental influence Placement coefficients on the Family Environment Scale (FES) can explain only a minor portion of the correlations for twins reared apart The influence of specific rearing environmental factors on adult personality was evaluated by analyzing the relationship between the FES and the CPI in this adoptee sample One FES factor (Cohesion vs Conflict) does correlate substantially with the CPI factor of Consensuality and may account for up to 24% of the variance in that factor, but the retrospectively gathered     

Responsibility and perfectionism in OCD: an experimental study

Cognitive models of obsessive-compulsive disorder (OCD) suggest a number of different variables that may play a role in the development and maintenance of obsessive compulsive symptoms [Freeston, M. H., Rhéaume, J., & Ladouceur, R. (1996) Correcting faulty appraisals of obsessional thoughts. Behaviour Research and Therapy, 34, 433-446]. This study's aim was to verify the effect of perfectionism and excessive responsibility on checking behaviors and related variables. Twenty-four moderately perfectionistic subjects (MP) and 27 highly perfectionistic subjects (HP) were submitted to a manipulation of responsibility (low and high). After each manipulation, they had to perform a classification task during which checking behaviors were observed. Results indicate that more checking behaviors (hesitations, checking) occurred in the high responsibility condition than in the low responsibility condition for subjects of both groups. After executing the task in the high responsibility condition, HP subjects reported more influence over and responsibility for negative consequences than MP subjects. These results suggest that high perfectionistic tendencies could predispose individuals to overestimate their perceived responsibility for negative events. Furthermore, perfectionism could be conceived as playing a catalytic role in the perception of responsibility. Results are discussed according to cognitive models of OCD.

Classroom Interactions,Dyadic Teacher–Child Relationships,and Self–Regulation in Socially Disadvantaged Young Children

This study examined the quality of the classroom climate and dyadic teacher–child relationships as predictors of self–regulation in a sample of socially disadvantaged preschool children (N?=?206; 52 % boys). Children’s self–regulation was observed in preschool at the beginning and at the end of the school year. At the middle of the preschool year, classroom observations of interactions were conducted by trained observers and teachers rated the quality of dyadic teacher–child relationships. Results from multilevel analyses revealed that teacher–child closeness predicted improvements in observed self–regulation skills. Children showed larger gains in self–regulation when they experienced closer teacher–child relationships. Moreover, a moderating effect between classroom instructional quality and observed self–regulation was found such that children with low initial self–regulation skills benefit the most from classrooms with higher classroom quality. Findings have implications for understanding the role of classroom social processes on the development of self–regulation.     

Affective matching of odors and facial expressions in infants: shifting patterns between 3 and 7 months

Recognition of emotional facial expressions is a crucial skill for adaptive behavior. Past research suggests that at 5 to 7 months of age, infants look longer to an unfamiliar dynamic angry/happy face which emotionally matches a vocal expression. This suggests that they can match stimulations of distinct modalities on their emotional content. In the present study, olfaction–vision matching abilities were assessed across different age groups (3, 5 and 7 months) using dynamic expressive faces (happy vs. disgusted) and distinct hedonic odor contexts (pleasant, unpleasant and control) in a visual‐preference paradigm. At all ages the infants were biased toward the disgust faces. This visual bias reversed into a bias for smiling faces in the context of the pleasant odor context in the 3‐month‐old infants. In infants aged 5 and 7 months, no effect of the odor context appeared in the present conditions. This study highlights the role of the olfactory context in the modulation of visual behavior toward expressive faces in infants. The influence of olfaction took the form of a contingency effect in 3‐month‐old infants, but later evolved to vanish or to take another form that could not be evidenced in the present study.     

Scene perception, gaze behavior, and perceptual learning in virtual environments.

More and more immersive environments are developed to provide support for learning or training purposes. Ecological validity of such environments is usually based on learning performance comparisons between virtual environments and their genuine counterparts. Little is known about learning processes occurring in immersive environments. A new technique is proposed for testing perceptual learning during virtual immersion. This methodology relies upon eye-tracking technologies to analyze gaze behavior recorded in relation to virtual objects' features and tasks' requirements. It is proposed that perceptual learning mechanisms engaged could be detected through eye movements. In this study, nine subjects performed perceptual learning tasks in virtual immersion. Results obtained indicated that perceptual learning influences gaze behavior dynamics. More precisely, analysis revealed that fixation number and variability in fixation duration varied with perceptual learning level. Such findings could contribute in shedding light on learning mechanisms as well as providing additional support for validating virtual learning environments.
