Differential non-target old/new effects in picture-target and word-target tasks

Location of peak (x, y, z)	Peak Z	N in cluster	Region	Brodmann area	Post hoc: old > new
Picture block non-target old/new > word block non-target old/new
0 28 −10	4.43	196	Medial frontal gyrus (sub-genual)	BA11	Pic*
−8 58 0	3.93	124	Medial frontal gyrus	BA10	Pic
−48 −66 46	4.34	169	Left inferior parietal lobule	BA39	Pic, Word*

Regions tabulated show significant (P < .001, cluster size > 65) differential non-target old/new effects for the picture compared to the word task using a bidirectional (F) test. Non-target old/new effects contrast activity for non-target hits and correctly rejected new items. Note that the analysis of differential target old/new effects by target material block returned no significant results (see Results). Regions are listed according to the direction of the difference as revealed by post-hoc comparisons (see Methods and Data Analysis Strategy;

^*indicates post-hoc tests reliable at P < .01, but not at P < .001
