• In other words, at present it is unclear what a valid setting for this parameter should be. [...]we think that it is extremely relevant to assess its influence on statistical inference. The statistical model included an experimental condition with 18 blocks with a block length of 20 s using an onset every 40 s. The same statistical analysis was performed with different image resolutions obtained within the normalization step in SPM12 followed by a subsequent spatial smoothing of 8-mm full width at half maximum.
