In an epilepsy cohort, changes of mind often corrected choices and were linked to lower confidence

We tested whether changes of mind (CoM) corrected choices and were linked to lower confidence in behavioral data from 21 patients in the OpenNeuro ds006253 (MetaRDK) SEEG cohort. The analysis used 5,740 trials and 645 CoM trials from snapshot 1.0.3. In the preplanned per-patient model controlling for accuracy, log response time, and coherence, confidence was lower on CoM trials (mean coefficient −0.112 SD; 95% CI −0.210 to −0.023; 15/21 patients; exact sign-flip p = 0.028; Holm p = 0.028). Accuracy on CoM trials was 0.643 (95% CI 0.590 to 0.698; 18/21 patients above chance; p = 4.4 × 10⁻⁵; Holm p = 8.8 × 10⁻⁵); 427 of 645 CoM trials ended correct and 218 ended in error. CoM trials were nevertheless less accurate overall than other trials, and an interaction test did not show higher confidence for corrective than error-ending CoMs. An exploratory model using movement-onset time estimated a larger confidence decrease (−0.432 SD). The study is behavioral only. The interpretation that CoMs corrected the choice depends on the assumption that the dataset's `correct` field records the final target click; if it records the first choice, that result would mean the opposite. CoM labels were taken from the authors, not recomputed from mouse trajectories.

    We used its list of OpenNeuro iEEG datasets to select ds006253 and to find the snapshot version.

  2. supportsIn 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 sci:sha256:7cc0290f6fbb2a3a47f55263ec2158dc03f19d84c4e37085f2351ee94cda6f36

    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).

    Its neural confidence test controls for accuracy, response time and coherence, but not for CoM. We show that CoM trials have lower confidence and longer movements, so CoM is a necessary covariate for that test.
