NCT03055884

Brief Summary

The purpose of this study is to investigate whether it is possible to accelerate learning and improve associative memory performance in healthy subjects, by (1) applying transcranial Direct Current Stimulation (tDCS) during a verbal paired-associate learning task and by (2) optimizing the learning method with repeated retrieval practice.

Outcome Measures

Primary Outcomes (1)

  • Associative Memory assessed by a Verbal Paired-Associate memory test

    Changes in performance in the Verbal Paired-Associate memory task is compared between the 4 groups (1. tDCS+verbal paired-associate learning task with repeated retrieval practice, 2. tDCS + verbal paired-associate learning task without repeated retrieval practice, 3. Sham tDCS+verbal paired-associate learning task with repeated retrieval practice, 4. Sham tDCS + verbal paired-associate learning task without repeated retrieval practice) to investigate the influence of tDCS and learning method on Associative Memory

    baseline and 1 week after the tDCS
