2 Clinical Trials for Various Conditions
This project is focused on the neural and behavioral correlates of two different videos games that will be used as training tools. The two video games, developed by the Games Learning Society research group at the University of Wisconsin-Madison (UW) and the Wisconsin Institute for Discovery, are tailored to train mindfulness, particularly the regulation of attention; and prosocial behavior, especially sensitivity to others, in adolescents. This study will evaluate the hypothesis that systematic playing of mindfulness and prosocial games will change brain function in specific attentional, social and emotional circuits in potentially beneficial ways, and will impact performance on cognitive tasks of attention, and on measures of social cue perception and the propensity to share and behave altruistically. The investigators will employ behavioral and functional MRI-based neuroimaging measures to evaluate the investigators hypothesis.
Background: - Previous studies have shown that people with certain types of brain damage may have particular problems paying attention and processing things that they see. Researchers are interested in comparing how people with brain damage and without brain damage process visual images. Objectives: - To better understand the areas of the brain involved in paying attention to things that are seen. Eligibility: - Individuals at least 18 years of age who either have had damage to one or both sides of specific parts of the brain (e.g., stroke, injury, certain neurosurgery procedures) or are healthy volunteers. Design: * The study involves 4 to 10 visits to the NIH Clinical Center over 1 to 2 years. Each visit will last approximately 2 hours. * Participants will be screened with a medical history and physical examination, and may have the cognitive testing described below during the same visit. * On the first visit and for at least one visit thereafter, participants will have cognitive testing to evaluate thinking and memory. These tests will be either written tests or computer-based tests. * Some participants will qualify for functional magnetic resonance imaging (fMRI) as part of the study. This part will involve a decision-making task that will be performed on a computer during the fMRI scan. Additional scans may be required as directed by the study doctors. * Some randomly selected participants will be asked to have magnetoencephalography (MEG), a procedure to record very small magnetic field changes produced by brain activity. * During the behavioral training, or fMRI or MEG scanning, participants may be monitored with equipment to track eye movements.
