Pre-response ERP measures were obtained from the mean voltage of the 100ms preceding the response for the N400 electrodes. Subject values are represented as circle outlines. Model predictions correspond to the variable assumed to underlie the same/different decision, which is the lowest activation value of the response word’s node in maintained semantics (i.e., residual activation for that word), after presentation of the response word. As seen in the figure, increasing prime duration differentiated same trials (A-A-A and A-B-B) from different trials (A-B-A and A-A-B). All values were z-scored separately (for average data results, for each subject, and for the model) within each prime duration.
