Primary outcomes
- Rey Auditory Verbal Learning Test (RAVLT) — 4 days after intervention administration
Rey Auditory Verbal Learning Test (RAVLT) is a test of verbal learning and declarative memory. During the test, 15 nouns that are read aloud for 5 consecutive trials. Each trial is followed by a free recall test (participant is asked to recall the words that were just read to them). The sum of correctly recalled words across 5 trials is called the total raw score. The raw scores on the total recall (number of words correct across trials 1-5) are converted to standardized T-scores (Mean=50; SD=10; range 20-100) based on participant age and gender. The scores below are presented as T-scores, with higher scores indicative of better performance.
