Fixing the stimulus-as-fixed-effect fallacy in task fMRI
Wellcome Open Research, 2016 AbstractMost fMRI experiments record the brain’s responses to samples of stimulus materials (e.g., faces or words). Yet the statistical modeling approaches used in fMRI research universally fail to model stimulus variability in a manner that affords population generalization--meaning that researchers’ conclusions technically apply only to the precise ...
