Rate of successful word-referent mapping. A) Percentage of rapidly mapped cell assemblies (CAs) across 100 learning trials in one-stage vs two-stage learning. The y-axis depicts, for each learning event, the percentage of CAs per network in which the word form was mapped sufficiently to the referent, allowing for reactivation of at least 10% of the object/action representation in referent extrasylvian areas (V1, TO, and AT for object words and M1_L, PM_L, and PF_L for action words) after auditory stimulation. This is computed across the different learning steps, on the x-axis. Error bars capture SE across networks. B) Proportion of correct vs incorrect referents reactivated across learning trials for two-stage learning. Green points depict the proportion of the correct referent representation that is reactivated after each learning event from just auditory stimulation. Red points depict the proportion of incorrectly activated referent representations, demonstrating that the networks did not make mapping errors. These results are separated by category-specific extrasylvian area, with “primary” corresponding to V1 for object words and M1_L for action words, “secondary” corresponding TO for object words and PM_L for action words, and “hub” corresponding to AT for object words and PF_L for action words. Error bars capture SE across CAs.
