fMRI results of the comparative analyses of ordinal and cardinal trials in the TEST and CONTROL tasks.
(a) The left posterior parietal cortex was activated more strongly in ordinal than in cardinal trials for both the TEST and CONTROL tasks (conjunction on a two-sample t-test with peak threshold P < 0.001 (uncorrected)). (b) The left striatum was activated more strongly in the ordinal trials than in the cardinal trials in only the TEST task (one-sample I-test with peak threshold P < 0.001 (uncorrected) and cluster threshold P < 0.001 (uncorrected)). **P < 0.01 in paired t-test. Error bars indicate the standard error of mean. We used uncorrected height (peak-level) and extent (cluster-level) thresholds of P < 0.001 for visualizing second-level group analyses.
