Region of interest analysis.

Region	repeat	novel	switch	repeat < novel	switch > novel	switch > repeat
Left intraparietal sulcus	3.89	3.85	3.99	−0.97	2.53*	2.32*
Right intraparietal sulcus	3.83	3.86	3.97	0.65	1.79*	2.67*
Lateral occipital gyrus (bilateral)	3.07	3.04	3.12	−0.98	1.62	0.89
Anterior insula (bilateral)	3.58	3.60	3.61	0.36	0.10	0.47
Premotor (bilateral)	4.45	4.47	4.50	0.59	0.46	0.78

These regions are functionally defined as regions more active during trials (regardless of condition) than rest at a corrected p < 0.05 (see Table 1). Left IPS was defined as activation from the large left-lateralized cluster in Table 1 located posterior to y = −47. The statistical contrasts are the same as Table 2. The first column provides the name from the region, and the next three columns report the t-score for that region (the mean value for the 10% most active voxels in that region) for each of the three conditions. Note that the t-scores for the repeat and switch conditions are actually the mean t-scores from the rTnD and nTrD and sTnD and nTsD relative to rest, respectively. The final three columns report the t-values (df = 20, where t = 1.724 is p < 0.05).
