A controlled, randomized design will be used in the present study. Patients will be randomly assigned (with stratification related to neglect severity) to PA (experimental) or sham (control) conditions and complete 10, 30-minute intervention sessions over approximately two weeks. These intervention sessions will involve a novel and simple computerized prism adaptation, Peg-The-Mole (PTM). Outcome measures will be collected before and after each treatment, as well as at baseline, and a three month follow-up over the phone.
