    • Internalizing problems and attentional control: Effects on cardiac autonomic responses after the induction of negative affect 

      Andersen, Tonje Grønning; Fiskum, Charlotte; Aslaksen, Per M; Flaten, Magne Arve; Jacobsen, Karl Henry (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Individuals with internalizing problems differ in levels of attentional control (AC), and this heterogeneity could be associated with differences in autonomic arousal. The present study investigated whether AC moderated the effect of internalizing problems on self-reported experience and autonomic nervous system (ANS) responses after the induction of negative affect. Children aged 9–13 years were ...

    • Non-linear heart rate variability as a discriminator of internalizing psychopathology and negative affect in children with internalizing problems and healthy controls 

      Fiskum, Charlotte; Andersen, Tonje Grønning; Bornas, Xavier; Aslaksen, Per M.; Flaten, Magne A.; Jacobsen, Karl (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-23)
      Background: Internalizing psychopathology and dysregulated negative affect are characterized by dysregulation in the autonomic nervous system and reduced heart rate variability (HRV) due to increases in sympathetic activity alongside reduced vagal tone. The neurovisceral system is however, a complex nonlinear system, and nonlinear indices related to psychopathology are so far less studied in children. ...
