TTie purpose of the present study was to replicate this finding as well as to investigate its robustness In terms of skill loss and reacquisition. Thus, we compared the AIM-dyad training protocol to a standard individual protocol regarding the acquisition of a complex skill (i.e.. Space Fortress; cf . More importantly, skill loss after an 8-week non-practice interval and skill re-acqulsition was also investigated. Despite half as much hands-on practice, the performance of dyadic trainees did not differ from that of individuals on tests of skill acquisition, loss, and re-acquisition. These findings provide strong support and justification for the ongoing use of innovative dyadic protocols for the training of pilots and navigators in both military an non-military settings.

Developing Technical Expertise in Emergency Medicine—The Role of Simulation in Procedural Skill Acquisition

“…Procedural skill decay refers to the loss of some or all of the skills necessary to perform a procedure after a period of nonuse. Different terms have been used to describe this process including: knowledge decay/retention, skill decay/retention, and skill durability 128 . This concept is important especially in EM, because EPs are expected to maintain competency in a wide variety of procedures, even those rarely performed.…”

Managing Medical Equipment Used by Technology-Dependent Children

“…Evidence from simulation literature has shown that if a prolonged period of time elapses between procedural training and application of the new skill (the "retention interval"), procedural skill decay will inevitably occur. 22 Therefore, future studies are also needed to investigate the true frequency of training needed to demonstrate improved performance and maintenance of medical equipment management skills.…”

Improving assessment of procedural skills in health sciences education: a validation study of a rubrics system in neurophysiotherapy

“…These questions could also be addressed in postgraduate studies. Research has repeatedly shown that procedural skills decay after extended periods of nonuse [106]. The retention of these skills is most affected by the teaching methodology used (e.g.…”
