Subclaims¶

q3 i? Confidence in correct responses was higher within than across spatial boundaries (p = 0.004), and marginally higher within than across mission boundaries (p = 0.055). → Yue Li 2025

q3 · i? · causal · r?

LMM on confidence for correct recency test trials only (21% unsure, 34% fairly sure, 45% quite sure). The same model also reported a "significant main effect of crossi ng the spatial boundary ( p = 0.004)"; overall R2 of the confidence model was 71%.

"We found a marginally significant main effect of crossing the mission boundary (p = 0.055) on confidence, indicating higher confidence in correct responses when participants were within the mission boundary compared to when they crossed the mission boundary (Table 2)."

Discussion¶

Related Claims¶

• Temporal order memory accuracy and confidence both increased significantly with block order across the six-block VR experiment — related
• With inter-object intervals held comparable, memory accuracy is significantly higher for the within-Mission/across-Spatial level than for the across-Mission/within-Spatial level — related
• Crossing a spatial boundary shows no significant effect on temporal order memory accuracy, and no significant mission-by-spatial interaction, in the VR salesperson task — reports the opposite
• Crossing a conceptual (mission) boundary significantly impairs the accuracy of temporal order memory in an interactive VR episodic memory task — related
