q2 i? In Andersen et al.'s mastoidectomy training, the massed group's performance started to decline after just 4 repetitions while the spaced group's performance asymptotically increased towards a proficiency plateau. → Fahl Jan Torge 2023

q2 · i? · review · r3

Prospective cohort study (n=43 undergraduate medical students) using a visible ear simulator for mastoidectomy, six sessions spaced at least 3 days versus one massed day. The review reports the massed group "initially showed faster skills acquisition" but declined, while the spaced group rose toward a plateau.

"although the massed training group initially showed faster skills acquisition, their performance started to decline after just 4 repetitions, while the performance of the spaced group asymptotically increased towards a proficiency plateau"
