The Contribution of Childhood Negative Emotionality and Cognitive Control to Anxiety-Linked Neural Dysregulation of Emotion in Adolescence.

The Contribution of Childhood Negative Emotionality and Cognitive Control to Anxiety-Linked Neural Dysregulation of Emotion in Adolescence. J Abnorm Child Psychol. 2018 Jul 31;: Authors: Davis MM, Miernicki ME, Telzer EH, Rudolph KD Abstract Adolescence is a period of heightened emotional reactivity, which is reflected in greater activation in emotion-processing regions of the brain in adolescents relative to children and adults. While elevated emotional reactivity and poor emotion regulation are thought to contribute to the rise in rates of internalizing psychopathology, including anxiety, during adolescence, little research has examined factors predicting individual differences in the neural regulation of emotion that can explain why only some adolescents experience anxiety. To address this gap, the present study examined the contribution of childhood negative emotionality (NE) and cognitive control (CC) to neural processing of emotion in adolescence. A sample of 44 girls (M age = 15.5, SD = 0.35) was selected from a longitudinal study that included self, parent, and teacher report of NE and CC between 2nd and 7th grades. Following 9th grade, girls completed an emotion regulation task during a functional magnetic resonance imaging scan. Neural regulation of emotion was indexed by functional connectivity between the amygdala and right ventrolateral prefrontal cortex (rVLPFC) during emotion regulation. Analyses revealed that ...
