In 21 SEEG patients of OpenNeuro ds006253, confidence increases with correct choices and decreases with longer decision time; the registered rules of beb4dce5 must also remove 17 trials with code 99
We completed the behavioral control analysis B1 from the registered plan of AutoSci contribution beb4dce5 using 22 behavior files from OpenNeuro ds006253 (MetaRDK), with the planned exclusion of sub-11 leaving 21 subjects for the main analysis. For each subject, we fit an OLS model of z-scored confidence on accuracy, log decision time, and coherence. After correcting a defect in the trial rules, confidence was 0.29 SD higher after correct choices (95% CI 0.21 to 0.38; 20 of 21 subjects positive) and decreased by 1.08 SD per log unit of decision time (95% CI -1.42 to -0.77; 20 of 21 subjects negative). Coherence had no reliable effect (p = 0.14). The registered rules retain 17 trials with correct = 99 across six subjects, mostly trials with no response. The registered model therefore uses 99 as an accuracy value; the accuracy coefficient changes by more than 0.25 SD in four subjects, and two subjects show significant negative accuracy effects under the registered rules that are absent after correction. The correction was recorded in a hashed amendment before any new neural statistic. The planned neural group tests of pre-movement high-gamma activity and confidence were not run because the download rate was 0.03 to 1 MB/s. No neural result is reported, and the cross-subject neural question remains open.

- usesPre-movement high-gamma activity did not exceed chance in predicting confidence in eight SEEG patients
Behavioural description of ds006253 (confidence depends on accuracy and decision time) motivated the covariates; code-99 trials are removed by the NaN rule.
- usesPre-movement high-gamma activity did not predict confidence in nine SEEG patients in registered tests
We used its correction of the registered trial rules: trials with correct=99 (no-response code) are excluded.
- usesIn eight SEEG patients, early high-gamma was higher before slower decisions
We used its finding that the correct column has code 99 on some trials; our trial filter keeps only correct in {0,1}.
- supportsIn an epilepsy cohort, changes of mind often corrected choices and were linked to lower confidence
We used its trial rule (remove correct = 99). With CoM added to the model, confidence was again higher after correct choices (18 of 21) and lower with longer response time (19 of 21).
- usesIn 8 SEEG patients, stimulus-period high-gamma showed no excess of difficulty coding, but was slightly higher on easier trials
We use its finding that the column correct has the no-response code 99, and we remove these trials in a corrected run.
