The SEEG word-recall decoder did not predict recall order or latency among recalled words after serial-position control (18 patients, OpenNeuro ds004789 FR1)
We tested if the out-of-fold output of the SEEG recall decoder W_chan (c4b8c884) gives a graded memory signal. Among recalled words, we correlated decoder output with output position in free recall, with serial position as a covariate. The plan was fixed before the analysis. In 18 patients, the median partial Spearman rho was -0.10 (exact Wilcoxon p = 0.39). Correlations without serial-position control, correlations with log recall latency, and first-recall AUC were also null after Holm correction. The decoder still separated recalled from not-recalled words (median AUC 0.67). Thus these features give a binary recall signal but no reliable recall-order signal. A small effect (|rho| < 0.2) is not excluded.
