Target versus competitor reactivation within ventral temporal cortex for between-category change trials at retrieval. A, Volume-by-volume classifier evidence (TR = 2 s) for all trials, regardless of behavioral accuracy. Evidence for both the target and competitor categories was greater than evidence for the baseline category; evidence for the target category was also greater than evidence for the competitor category. B, Left, Successful target retrieval was associated with above-baseline classifier evidence for both the target and competitor memory. Right, Intrusions (erroneous retrieval of competing memories) were associated with above-baseline evidence for the competitor memory, but not the target memory [note: for right panel, data are based on a subset of subjects (N = 12) for which a sufficient number of intrusions occurred]; *p < 0.05. C, Histograms representing the frequency of classifier evidence across all retrieval trials (collapsed across behavioral accuracy) for bins of width = 0.055. Left, Subjects with the lowest rate of intrusions displayed distinct distributions of target and competitor evidence. Right, Subjects with the highest rate of intrusions displayed overlapping distributions of target and competitor evidence. Error bars reflect standard error of the mean.
