The child may express anger and affection at a level expected of a much younger child. There can be a limited vocabulary to describe emotions and a lack of subtlety and variety in emotional expression. When other children would be sad, confused, embarrassed, anxious or jealous, the child may have only one response, and that is to feel angry. The degree of expression of negative emotions such as anger, anxiety and sadness can be extreme, and described by parents as an on/off switch set at maximum volume.
