Figure 4.

Overt and Covert direct contrasts. A, Overt Noun Definition > Covert Noun Definition. B, Overt Counting > Covert Counting. C, Overt Noun Definition > Overt Counting. D, Covert Noun Definition > Covert Counting. For the six contrasts, sagittal slices are shown, from left to right, x = −63, −53, −43, −13, −3, 7, 37, 47, 57, and the orthogonal coronal slice. Z-statistic images were thresholded using clusters determined by z > 2.3 and a corrected cluster significance threshold of p < 0.05. Results are displayed on a standard brain template (MNI152).
