Selective Mutism

Selective Mutism is characterized by a consistent failure to speak in certain social situations when there is an expectation to speak. This happens despite the ability to speak in other situations. For example, a child speaks to her parents and siblings at home just fine, but will not talk at all to her teacher or peers at school. Like other Anxiety Disorders, these problems cause significant distress or impairment in major areas of life, like work, school, or relationships.
