Interpreting response time effects in functional imaging studies.
Bottom Line: However, even for contrasts designed to tap neural effort, activity remained after factoring out the RT-BOLD response correlation.This may reveal unpredicted differences in neural engagement (e.g., learning phonological forms for pseudowords>words) that could further the development of cognitive models of reading aloud.Our framework provides a theoretically well-grounded and easily implemented method for analysing and interpreting RT effects in neuroimaging studies of cognitive processes.

Mentions: Unless otherwise stated all reported results were significant at p < .001 whole brain voxel-wise uncorrected, and p < .05 cluster-level family wise error (FWE) corrected. Contrasts of parameter estimates are displayed on slices of the MNI canonical brain in Figs. 3, 4, and 5.
