Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental
Participants will receive one anodal tDCS at 1 mA intensity over the left superior temporal gyrus (T3 in 10-20 international system) and the cathode tDCS over the right orbitofrontal area (Fp2 in 10-20 international system). tDCS will be delivered for 20 minutes during fluency intervention for six consecutive days.
Anodal tDCS
1 mA anodal tDCS positioned over left superior temporal gyrus and the cathode placed over the occipital lobe. The tDCS stimulation will be delivered for 20 minutes on 6 intervention days.
fluency intervention/ Delayed Auditory Feedback
Each participant complete three tasks include reading, conversation, and narration. Delayed auditory feedback will be used during these tasks. Each treatment session will take 20 minutes.
Sham Comparator
Participants will receive sham tDCS while the one anode electrode will be positioned over the left superior temporal gyrus and the cathode will be placed over the right orbitofrontal similar to the active mode. The sham stimulation will break down after 30 seconds at the beginning of 20 minutes of fluency intervention for six consecutive days.
fluency intervention/ Delayed Auditory Feedback
Each participant complete three tasks include reading, conversation, and narration. Delayed auditory feedback will be used during these tasks. Each treatment session will take 20 minutes.
Sham tDCS
The anodal tDCS positioned over left superior temporal gyrus and the cathode placed over the occipital lobe. The current of sham stimulation will involve 30 seconds of stimulation at the beginning of the 20 minutes on 6 intervention days.
