In fMRI research, one often aims to examine activation in specific functional regions of interest (fROIs). Current statistical methods tend to localize fROIs inconsistently, focusing on avoiding detection of false activation. Not missing true activat

Background To increase power when analyzing fMRI data, researchers often define functional regions of interest (fROIs). It is crucial that this fROI is defined with an optimal balance between both false positives and false negatives to ensure maximal

fMRI localizer tasks are often used to define subject specific functional regions of interest (fROIs) that contain the relevant features for subsequent analyses. fROIs are typically small and show large interindividual differences in extent and effec

Instructions play an important role in daily life. Instructions specify response rules and the conditions in which these apply. In recent years, research has emphasized the importance of instructions, and an increasing number of studies have demonstr

There is increasing concern about statistical power in neuroscience research. Critically, an underpowered study has poor predictive power. That is, findings from a low-power study are unlikely to be reproducible, and thus a power analysis is a critic
