The first section contains regions showing a main effect of task, with overall activity higher in the numerical comparison than the recognition task. The second section contains regions also showing a main effect of task but in the opposite direction (recognition greater than comparison). The third section contains the region showing a significant main effect of stage; this region showed overall greater activation for both tasks in Stage 2 relative to Stage 1. The rightmost two columns show mean levels of activity (beta-weights averaged across subjects) for that condition. No regions showed a Task × Stage interaction, regions showing a significant effect of task did not show an effect of stage (and vice-versa). Thus, values are included only for the factor showing a significant effect in that region (i.e., Task for the top two sections and Stage for the bottom section). Values shown in parentheses indicate standard errors of the mean (n = 20).
