Significant values for the whole brain corrected for multiple comparisons for the pre- and postchange at P-corr < 0.05 are presented. The significant activity presented is masked from flexible factorial models that test the assignment-by-time interaction, and values were significant when tested in paired sample t tests to account for the between- and within-subject nature of the data. dACC, dorsal anterior cingulate cortex; SSB, sugar-sweetened beverage; vmPFC, ventromedial prefontal cortex.
Coordinates presented in Montreal Neurological Institute space.
Cohen’s d was calculated as a measure of pre- and posteffect size, which was then transformed to r because this is a universal measure of effect size (29).
No significant effects were observed with the (pre)receipt of both juices − (pre)tasteless solution receipt − (post)receipt of both juices − (post)tasteless solution receipt contrast.
