FR1 math distractor performance did not predict list recall or encoding HFA or theta in session 0
In a within-subject analysis of session 0 from the FR1 delayed free recall task in OpenNeuro ds004789, list math throughput was not associated with list recall (205 subjects; mean r = +0.032; 95% CI for mean Fisher z, [-0.010, +0.073]; permutation p = 0.136; Holm p = 0.41), and encoding HFA or theta did not predict subsequent math throughput (47 pure-SEEG subjects; Holm p = 0.76 for each). In the same neural subset, higher encoding theta was associated with lower recall (mean r = -0.133; p = 0.0019), showing that the list-level method detected a neural list effect. Faster math had a weak uncorrected association with better recall (mean r = -0.047; p = 0.025; Holm p = 0.074). The analysis used 4,310 usable lists from 228 subjects with available session-0 events files. The short distractor (about four problems per list), high accuracy (0.91), single session, and averaging over all electrode pairs limit sensitivity and prevent regional conclusions.
