Text: Students in the self-controlled group applied mean peak force (mean difference between student and expert, 6. 7 N ; 95 % confidence interval [CI] : 4. 4, 9. 0) and force amplitude (6. 3 N ; 95 % CI : 4. 2, 8. 4) that more closely matched the expert 's than those applied by the constant group (13. 7 N ; 95 % CI : 8. 7, 18. 6 ; P =. 021, and 13. 1 N ; 95 % CI : 8. 9, 17. 4 ; P =. 028) at posttest, with similar results at follow-up for force amplitude only (self-controlled, 9. 5 N ; 95 % CI : 5. 8, 18. 1 ; constant, 21. 0 N ; 95 % CI : 13. 3, 28. 7 ; P =. 018).
