Following ascertainment of study eligibility, participants will undergo a baseline assessment consisting of a clinical interview, neurocognitive assessments, EEG, attention bias assessment, and self report questionnaires. Study participants will then receive 12 sessions of AMP treatment over the course of three weeks. All youngsters and their families will be reassessed at treatment endpoint (week 4). Participation will take a total of about 24 hours over the course of six weeks. Participants who are treatment responders may be asked to return approximately 3 months after completing treatment for a follow-up assessment.
