Subclaims¶

q3 i? Of 16 studies comparing performance by training level, all but one found UP differences favoring more experienced participants. → Iop A. 2022 q2 i? UP differences were not consistent across all metrics, and some less experienced outliers outperformed peers and superiors. → Iop A. 2022

Review synthesis of 16 studies (Table 3) testing realism via the UP–training-level relationship: differences favoring experienced participants appeared in all but one study, but metrics were inconsistent and junior outliers sometimes outperformed seniors.

"We found 16 studies that investigated performance differences based on level of training or experience (Table 3). Differences in UP favoring the more experienced participants were found in all studies except one [67]. As expected, these UP differences were not consistent across all metrics assessed [57,58,59,65], and there were outliers among the less experienced who clearly outperformed their peers, and at times, even their superiors [31,57]."

• Less experienced users benefit more from XR training, though evidence is mixed across longitudinal studies — related
• Senior trainees scored approximately 30–40% higher than juniors on technical performance measures in simulation studies — a narrower finding that bears on this claim
• XR-based training is associated with improved user performance in cranial neurosurgical simulation compared to non-XR conditions — related
