Article
Full-text available
Processing and recognizing facial expressions are key factors in human social interaction. Past research suggests that individuals with autism spectrum disorder (ASD) present difficulties to decode facial expressions. Those difficulties are notably attributed to altered strategies in the visual scanning of expressive faces. Numerous studies have de...
Article
Full-text available
Two original studies explored relationships between visual attention of children with ASD (candidates for receiving a service dog) and their behaviors during their first interaction with a service dog. The first study consisted in video behavioural analyses of 16 children with ASD interacting with a service dog. During the interaction with a servic...
Presentation
Comparaison des approches catégorielles et des approches multidimensionnelles comme le Research Criteria Domain Criteria (RDoC) pour étudier le stress chronique chez des patients vus à l’urgence psychiatrique.
Article
Full-text available
In 2008, the National Institute of Mental Health (NIMH) announced that in the next few decades, it will be essential to study the various biological, psychological and social ‘signatures’ of mental disorders. Along with this new ‘signature’ approach to mental health disorders, modifications of DSM were introduced. One major modification consisted o...

Selon des etudes precedentes, l’evenement que represente la transition du primaire au secondaire suscite une augmentation significative de cortisol (hormone de stress) chez les adolescents. Le programme DeStresse et Progresse est un programme de prevention du stress et de ses troubles associes, issu des travaux realises ces dernieres annees dans le...

Earlier age of menarche is believed to confer greater vulnerability to depressive symptoms via increased reactivity to stressors associated with adolescence. In this longitudinal study, we measured depressive symptoms and salivary cortisol levels in 198 boys and 142 girls between the ages of 11 and 13 tested four times during Grade 7 as they transi...

Despite the increasing pervasiveness of mobile computational technologies, knowledge about psychiatric patients' preferences regarding the design and utility of mobile applications is very poor. This paper reports on a pilot-study that involved 120 psychiatric patients in the development of a mobile application (app) that is being used for data ent...
Article
Various studies have shown that increased activity of the hypothalamic-pituitary-adrenal (HPA) axis can predict the onset of adolescent depressive symptomatology. We have previously shown that adolescents making the transition to high school present a significant increase in cortisol levels, the main product of HPA axis activation. In the present s...
Article
Dominance has been conceived for a long time in terms of asymmetry in agonistic conflicts. But this conception has shown its limits in the complexity of children's social worlds. Today, dominance is rather conceived in terms of asymmetry in resource control within children's dyads. Some observational studies have been done in this context, but only...
Article
Japanese quail of lines selected for high (HSR) or low (LSR) levels of social reinstatement (SR) behaviour were reared in groups of three. At 3 and 6 weeks of age, one group member was replaced with an unfamiliar conspecific bird. Behaviour following introduction of the intruder was similar at both ages. Quail of both lines spent more time immobile...
Article
Inter-individual distances (IIDs), during open-field tests, were measured in single sex pairs of quail of lines divergently selected for high (HSR) or low (LSR) levels of social reinstatement (SR) behaviour. Tests were carried out when the chicks were 1-, 3- and 6-weeks of age. IIDs were established within 1 min and remained stable thereafter. In H...
Article
Japanese quail from two lines selected for high (HSR) or low (LSR) levels of social reinstatement behaviour were permanently placed from 2 days to 6 weeks of age in a situation where one tested animal had the choice between being in social contact with a stimulus animal in a bare compartment of the cage or out of visual contact with the stimulus an...
Article
1. Energy balance of adult hens divergently selected for high (R + ) or low (R- ) residual food consumption was investigated using indirect calorimetry. Three experiments were conducted: feeding behaviour of individual hens, hens having free access to food or fasting and hens tube-fed at 70, 100 or 130% of the control intake of both lines. 2. R + h...
