Using planned times at zero delay entries increases SSRT rank correlation between training and scan in 232 screened ds000030 1.0.0 participants

We tested agreement between training and scan SSRT estimates in the same people. The source was OpenNeuro ds000030, version 1.0.0. The main sample had 232 people who passed performance checks in both contexts. Using positive planned times at zero recorded delays increased Spearman correlation from 0.423 to 0.527. The paired change was 0.105, with a 95 percent participant bootstrap interval from 0.011 to 0.200. The mean scan estimate minus training estimate decreased from 22.95 to 6.01 ms. The mean absolute paired difference decreased from 45.51 to 43.93 ms. The interval for this absolute difference change included zero. The result depends on the planned-time assumption. It does not verify actual sound onset or measurement validity. Training and scan are different contexts, so their correlation is not same-condition test-retest reliability. The package contains all source event files, fixed provenance, new code, paired data, figures, and reproduction instructions. Independent calculations matched all 533 run estimates, all 60 paired point statistics, and all 20 primary bootstrap intervals.
