High contextual interference (CI) practice schedules moderately benefit motor skill retention, especially in older adults. However, this effect is less pronounced in applied settings and young participants.
Area of Science:
- Motor Learning
- Cognitive Psychology
- Sports Science
Background:
- The contextual interference (CI) effect on motor skill acquisition has been studied since 1966.
- Despite widespread advocacy, the CI effect's impact on retention has faced scrutiny.
- Existing literature requires a comprehensive review to clarify CI's influence on motor learning retention.
Purpose of the Study:
- To conduct a systematic literature review and meta-analysis on the contextual interference effect.
- To determine the specific impact of different practice schedules on motor skill retention.
- To investigate moderating factors such as participant age and setting.
Main Methods:
- A systematic search of six major databases (Scopus, EBSCO, Web of Science, PsycINFO, ScienceDirect, Google Scholar) identified 1255 articles.
- Full texts of 294 studies were screened, with 54 included in the meta-analysis.
- Two meta-analysis models (three-level mixed model, random-effects model) were employed to analyze the data.
Main Results:
- High CI demonstrated a statistically significant, medium beneficial effect on motor skill retention across the general population.
- Random practice schedules significantly enhanced retention in laboratory settings but showed a negligible effect in applied settings.
- The positive impact of random practice on retention was substantial in older adults (large effect size) and adults (medium effect size), but insignificant in young participants.
Conclusions:
- Random practice schedules, a form of high contextual interference, generally enhance motor skill retention.
- The effectiveness of random practice is context-dependent, showing greater benefits in controlled laboratory environments compared to applied settings.
- Age is a significant moderator, with older and adult populations benefiting more from random practice for skill retention than younger individuals.
