Emotional Processes in Adults With Intellectual Developmental Disorder

Emotions play a crucial part in the quality of life, interpersonal relationships and mental health in general. In adults presenting with intellectual developmental disorder (IDD), emotional abilities may be hindered, thus leading to more challenging behaviors. A better understanding of emotional processes of adults with IDD may help improve the efficiency of behavioral interventions and better improve their quality of life. The primary goal of this study is to better characterize the abilities and weaknesses of adults with IDD concerning their emotional processes, in comparison to a healthy population. The secondary goals are : * to determine if these difficulties are underlined by oculomotor and attention (auditory and visual) processes * to determine if behavioral difficulties, as reported by the families of adults with IDD, are underlined by specific difficulties in facial emotion recognition, emotion identification in context and/or identification of vocal emotions.
