Response Inhibition Training for Individuals With Trichotillomania

This study tests a computerized cognitive training program designed for young individuals with compulsive hair pulling (also known as trichotillomania;TTM). Research suggests that individuals with TTM are characterized by poor cognitive abilities to suppress irrelevant response. This ability is called response inhibition. The current study tests a cognitive training program designed to improve individuals' cognitive abilities of response inhibition through a 8-session computerized training program. The investigators hypothesize that those who complete the response inhibition training program will show a greater reduction in hair pulling symptoms, compared to those assigned to a waitlist group.
