Dyadic versus individual training protocols: Loss and reacquisition of a complex skill

It has been consistently demonstrated that the active interlocked modeling (AIM) protocol, a dyadic training protocol developed by W. L. Shebilske. J. W. Regian, W. Arthur, Jr., and J. A. Jordan (1992), achieves a 100% increase in training efficiency over a standard individual protocol. The present study sought to replicate this finding as well as to investigate its robustness in terms of skill loss and reacquisition. Thus, the authors compared the AIM-dyad protocol with a standard individual protocol. Despite half as much hands-on practice, dyadic trainees did not differ from individuals on tests of skill acquisition, loss after an 8-week nonpractice interval, and reacquisition of a complex skill. The findings provide strong support and justification for the ongoing use of innovative dyadic protocols for the training of pilots and navigators in both military and nonmilitary settings.
