Modulating Context Generalization Through Transcranial Direct Current Stimulation

NCT03374605 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

No results posted yet for this study

Summary

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.

Conditions

  • Anxiety and Fear

Interventions

DEVICE

active tDCS

15 minutes of active (2mA) high definition tDCS will be applied to the participant's skull. The anodal electrode will be placed over 10-20 EEG coordinate AF7 and cathodal electrode over coordinate Fz.

DEVICE

sham tDCS

15 minutes of sham high definition tDCS will be applied to the participant's skull. The anodal electrode will be placed over 10-20 EEG coordinate AF7 and cathodal electrode over coordinate Fz.
