repetmus

Repetmus is a conceptual unit used in cognitive science and education to quantify the learning gains attributed to repetitive practice. It summarizes how much a learner improves when a task is practiced repeatedly under similar conditions, separating short-term fluctuations from systematic progress.

The term is a neologism formed from repetere, meaning to repeat, and a suffix pattern used in theoretical units. It was proposed in the early 2010s by researchers studying the dynamics of skill acquisition, with the aim of providing a common metric across experiments.

Measurement of a repetmus score is typically derived by combining the number of repetitions with an index of improvement per repetition, then normalizing for task difficulty and fatigue. One common formulation multiplies the repetition count by the average gain in performance per session, then adjusts for baseline ability. The score is unitless or given in a standard scale to enable cross-study comparisons.

Applications. Repetmus has been used in experiments on motor learning, language practice, and cognitive training to compare training schedules such as spaced repetition and massed practice. It also informs optimization of curricula and rehabilitation protocols.

Limitations. The construct depends on operational definitions of improvement and task difficulty, which vary by domain. Critics note that repetmus may obscure qualitative changes in strategy or error patterns, and cross-domain comparisons require careful standardization.
