简要总结
Behavioral adaptation is particularly relevant to anxiety and related disorders, where exposure-based therapies rely on such adaptation as part of behavior therapy.. However, while initial fear reactions generalize easily across contexts, subsequent adaption of behavior through learning is context-specific. The primary goal of this study is to investigate whether transcranial direct current stimulation (tDCS) can be used to acutely impact generalization of subsequent learning across contexts in an experimental paradigm. As part of this study, participants will complete a clinical interview and questionnaires, as well as a computer task asking them to make choices between stimuli on the screen and during which they may or may not receive tDCS.
