A summary of the presentation of randomized stimuli. Facilitation phase: one set of pictures were presented three times on two separate occasions (six times total), simultaneously with a semantic auditory question, for yes/no response by computer mouse button (LT prime). Experimental phase (during scan): the long-term facilitated set were presented again for naming (LT target); one set of pictures were presented twice - once as a prime along with an auditory question for yes/no response (ST prime) and then presented again (6 to 8 trials later) for naming (ST target); and one set of unfacilitated pictures were also presented once for naming (UN) (referred to as the “known” condition for participants with aphasia). For control participants, an additional set of unfacilitated non-critical fillers were also presented.
