Primary outcomePrimary: RTs for Picture Naming With the Factors Language (L1, L2) and Block (Switching, Non-Switching) — 1103.32; 1107.26; 1098.82; 1158.91 Milliseconds — p=0.932
Summary
The purpose of this study is to investigate whether theta burst stimulation (TBS) over the left dorsolateral prefrontal cortex (DLPFC) influences language switching and cognitive flexibility. The experimental paradigm will assess the impact of inhibitory and excitatory prefrontal stimulation by TBS versus sham-TBS over the DLPFC in healthy bilinguals.
