Speed of attention. Mean (± EM) change-from-baseline performance on “speed of attention” (derived from collapsing reaction time data from “numeric working memory”, “choice reaction time” and the “Rapid Visual Information Processing” task) on Day 1 (repetition 1 = post-dose repetition 1 on Day 1, repetition 2 = post-dose repetition 2 on Day 1) and following 28 days of supplementation with 475 mg Sideritis scardica (SS), 950 mg SS, active control (240 mg Ginkgo biloba) or placebo control (repetition 3 = pre-dose baseline on Day 28, repetition 4 = post-dose repetition 1 on Day 28 and repetition 5 = post-dose repetition 2 on Day 28). * p < 0.05, ** p < 0.01 and t = trend.
