Cognitive factors during development could underly the development of psychopathologies. Adults with an extra X chromosome (Klinefelter) showed impaired emotional arousal and emotion regulation. However, not much is known about the manifestation of these impairments in children with SCT’s. Therefore, the current study focused on emotional arousal and emotion regulation strategies in children with SCT’s. It was also investigated if age moderated the differences in emotional arousal and emotion regulation strategies. One hundred-seven children with SCT’s and 102 nonclinical controls participated in this study. A frustration inducing task (locked-box task) was used to induce heightened emotional arousal, which was measured continuously using heart rate measures. The emotion regulation strategies were coded during the task as well. Results showed lower emotional arousability in the children with SCT’s as well as less frequent use of constructive and venting emotion regulation strategies. The difference in avoidance strategy use was moderated by age. As the current study found evidence for the manifestation of emotion regulation problems in the childhood of individuals with SCT’s, it could be that these impairments are part of the underlying mechanism of the development of psychopathologies as well as possible targets for intervention.Show less
