Walking and periventricular leukomalacia: locomotor characteristics and brain imaging (MRI)

The aim of the present study was to compare the walking abilities in infants with and without periventricular leukomalacia and to see whether the severity of the brain damage was related to locomotor outcome of the infants at 12 and 18 months. 47 newborns were included in the study based on white matter abnormalities on ultrasound. Magnetic resonance imaging (MRI) recordings during the neonatal period were used to identify and quantify the location and severity of the brain lesions. Locomotor outcome was assessed in terms of disability at 12 and 18 months. The quality of walking, including global and segmental gait parameters, was measured for the infants who could walk independently at 18 months and compared to a group of healthy control infants. The number of children who could walk was related to the extent of white matter abnormalities seen on the neonatal MRI, but the quality of walking was not.     

Sensibiliser les filles à l'orientation vers les métiers scientifiques et techniques. Évaluation d'un dispositif

Girls’s diversification of career choices seem relatively resistant to training program. One explanation of this situation is the lack or even absence of procedures for evaluating this program. The article proposes an evaluation of a training program entitled “female engineer” designed exclusively for high school girls. The objective was to encourage female students guidance in this profession. The results are mixed and are interpreted in terms of cognitive dissonance and upward social comparison. The results also show the need to develop in the same time the training program and his evaluation.     

The Professional Insertion of Immigrants Born in the Maghreb: Challenges and Impediments for Intervention

Emigration as a means of improving living conditions in a society is viewed positively and is rooted in the will to escape economic and political constraints that seem to present no way out. The unemployment rate has increased in recent years several immigrant groups, especially people from the Maghreb and western Asia. As a result, these groups are significant clientele of employment integration programmes. In line with this observation, this article discusses the following dual objective: outlining the many obstacles Maghrebins face when they arrive in Quebec when integrating into the employment market and discussing the intervention strategies offered.     

Time causes forgetting from working memory

Although forgetting in the short term is a ubiquitous phenomenon, its exact causes remain undecided. The aim of the present study was to test the temporal decay hypothesis according to which memory traces fade away with time when attention is diverted by concurrent activities. In two experiments involving complex span tasks, adults were asked to remember series of items (either letters or spatial locations) while verifying multiplications. The duration of processing was manipulated by presenting multiplications either in word (three    ×    four    =    twelve) or digit (3    ×    4    =    12) format, the former taking longer to solve, while the time available to restore memory traces after each operation was kept constant across conditions. In line with the temporal decay hypothesis, the longer solution times elicited by solving word multiplications resulted in poorer recall performance. The fact that longer processing times had a comparable effect on both verbal and visuospatial memory and that the difference between conditions remained stable from the first to the last trials makes it difficult to account for these findings by assuming that forgetting is exclusively due to representation-based interference or buildup of proactive interference.     

Internalization of the thin and muscular body ideal and disordered eating in adolescence: the mediation effects of body esteem

This study investigates body esteem factors (weight-esteem and appearance-esteem) as mediators of the relationship between ‘internalization of the ideal body figure’ and disordered eating behaviors (restrained, emotional and external eating) in a community sample of adolescent males (n = 810) and females (n = 1137) from the Ontario Research on Eating and Adolescent Lifestyles (REAL) study. Mediation models were examined using a bootstrapping approach to test indirect effects and indirect contrasts. In males, weight-esteem partially mediated the relationship between muscular ideal and restrained eating; appearance-esteem partially mediated effects in the emotional and external eating regressions. In females, both weight-esteem and appearance-esteem partially mediated the relationship between thin ideal and all three forms of disordered eating; weight-esteem was a stronger mediator for restrained eating, and appearance-esteem a stronger mediator for emotional and external eating. Body esteem is important to consider for prevention and treatment of disordered eating in both genders.     

CLIMATE CHANGE AND THE CLASH OF WORLDVIEWS: AN EXPLORATION OF HOW TO MOVE FORWARD IN A POLARIZED DEBATE

The current gridlock around climate change and how to address our global sustainability issues can be understood as resulting from clashes in worldviews. This article summarizes some of the research on worldviews in the contemporary West, showing that these (ideal‐typical) worldviews have different, and frequently complementary, potentials, as well as different pitfalls, with respect to addressing climate change. Simultaneously, the overview shows that, because of their innate reflexivity and their capacity to appreciate and synthesize multiple perspectives, individuals inhabiting integrative worldviews may have particular potentials with respect to addressing climate change. In the conclusion I argue that the policy challenge is to develop strategies that inspire the different worldview groups to actualize their potentials while mitigating their pitfalls, as well as to unite and mobilize them around a single vision that speaks to them all.     

How much could we boost scholastic achievement and IQ scores? A direct answer from a French adoption study

We observed 32 subjects whose biological parents were both unskilled workers. Abandoned at birth, the subjects had been placed at approximately 4 months of age into families spanning the top 13% of the socio-professional scale. The effects of this change in social class were estimated by comparisons with groups of children of unskilled workers observed in two large scale studies. An internal control group was also available for 20 of the 32 subjects: the biological half-siblings who had been reared in their ‘natural’ environment. The effects observed are an increase of 14 IQ points in the mean IQ score estimated with 2 tests and a reduction by a factor of 4 in the probability of repeating a grade. These are significant despite the small number of subjects; we have shown that the bulk of these effects cannot be attributed to methodological biases. Our observations thus provide a direct quantitative answer to the question posed by Jensen in 1969.
