Moreover, none of the interaction effects approached significance ( Affective Category × Memory , t (232) = 1.50, p = 0.13; Affective Category × Stimulation , t(232) = −0.22, p = 0.82; Memory × Stimulation : t (232) = −0.41, p = 0.68; Affective Category × Stimulation × Memory : t (203) = 0.71, p = 0.48).

Following up on the interaction effects approaching significance, we could observe that the taVNS and sham group reported similar familiarity‐based memory, t (120) = −0.78, p = 0.43, but the taVNS group showed a recollection‐based memory advantage, t (120) = 2.3, p = 0.01.
