A matched analysis of 22 people in ds005523 v1.0.1 gave no clear stimulation effect on inward recall error with equal person weights

We tested whether stimulation during learning changed inward recall error in OpenNeuro ds005523 version 1.0.1. The primary analysis used 1,218 reflected trial pairs from 22 people and 55 sessions, with equal weight for each person. The mean stimulation-minus-control difference was 0.223 virtual arena units (95% bootstrap interval -0.625 to 1.066). Twelve people had positive differences and ten had negative differences. The data gave no clear evidence of a mean change under this analysis; the interval permits a decrease or an increase and does not show that the effect is zero. The analysis used recorded stimulation flags and did not estimate separate anatomical effects or reproduce the original performance-based sample selection. The package preserves all 7,740 navigation events, checked trial pairs, analysis and retrieval code, source hashes, and verification records.
