Background: Individuals with intellectual and developmental disabilities are more likely to engage in problem behaviours than peers with typical development. The purpose of this study was to provide descriptive and qualitative information about problem behaviours in children with fragile X syndrome (FXS) and how families respond to these…

We evaluated whether narrating anger-provoking events promoted learning from those events, as compared with other responses to anger, and whether the effectiveness of narrative depended on age. In addition, we tested relations between anger reduction and learning and, in a subset of participants, between narrative quality and learning. A sample of…

Background: As a result of the COVID-19 pandemic, governments have implemented preventive measures towards reducing infections. These conditions can affect the mental health of children and adolescents; however, this has not yet been fully explored. Objective: The aim of the study was to analyze changes in symptomatology and positive emotions in…

The study's goals were twofold: (a) to examine the effectiveness of narrating an angry experience, compared with relying on distraction or mere reexposure to the experience, for anger reduction across childhood and adolescence, and (b) to identify the features of narratives that are associated with more and less anger reduction for younger and…

There have been long-standing differences of opinion regarding the influence of the face relative to that of contextual information on how individuals process and judge facial expressions of emotion. However, developmental changes in how individuals use such information have remained largely unexplored and could be informative in attempting to…

Methods: Participants consisted of 116 age and gender-matched CWS and TDC (3.04-8.11). Temperament was assessed with a Dutch…

Background: Individual differences in conduct problems arise in part from proneness to anger/frustration and poor self-regulation of behavior. However, the genetic and environmental etiology of these connections is not known. Method: Using a twin design, we examined genetic and environmental covariation underlying the well-documented correlations…
