Model RDMs tested in the current analysis where rows and columns of the matrices represent trials (i.e., single spoken words) and values indicate pairwise dissimilarity values across trials. A, LexComp model. B, SemComp model. C, SemDis model. D and E represent cohort activations of two example stimuli taken from the gating results: chicken and train. Cohort profiles indicate the change in activation of every candidate word over time. D, At word onset, all members in chicken's cohort are partially activated, resulting in high lexical competition. As more of the speech input is heard, the activation of competitor words decays and the target word's activation increases. E, Train's cohort profile shows high semantic competition due to low semantic overlap between the cohort candidates. Arrows mark the UPs.
