Emotional awareness supports emotion regulation. Psychologists have children "color in feelings" to assess emotional awareness, yet whether this relates to emotion regulation is unknown. The present study used a novel coloring task examining behaviors related to coloring in and dictating emotions to assess children's ( N =95) emotional awareness. Further, it was tested whether performance on this task predicted emotion regulation. Children's coloring behaviors indicating physiological emotional awareness predicted better emotion regulation. Results may inform the use of emotional awareness tasks in community and clinical settings. Findings also suggest that physiological emotional awareness may be a more salient clinical target in children.
