Study Summary

This trial will use transcranial direct current stimulation (tDCS) to study how it changes cognition, with a focus on generalization (how training in one domain affects unlearned domains). The study will compare tDCS in healthy controls and patients with schizophrenia or schizoaffective disorder.

Eligible Conditions
  • Schizophrenia
  • Transcranial Direct Current Stimulation
  • Schizoaffective Disorder
