Table 1.
Mean BOLD change (beta) in each of the regions activated during novel picture processing regions for novel pictures or for pictures that were repeated with massed or distributed repetition, the F- statistic testing the main effect of repetition (novel, massed, distributed), and the pattern of significant differences in follow up comparisons. All of the effects of repetition in the novel picture processing regions are repetition suppression effects.
