Retrieval practice improves verbal long-term memory but electrical stimulation decreases recall

Takeaway

  • Transcranial direct current stimulation (tDCS) of the prefrontal cortex impairs verbal long-term memory that is enhanced by retrieval practice.

Why this matters

  • Electrical brain stimulation has been considered to improve verbal long-term memory however the impact may vary depending on behavioural techniques used concomitantly.
