based analysis or Statistical Parametric Mapping (SPM) yields inconsistent results across studies. It is difficult to challenge the validity
of SPM results in published works and review submissions because the nature
of the immense datasets that underlie VBA results prohibits its presentation
in journals. In this abstract we use a
simple data set to explore sources of type I errors in areas that often yield
positive results and present findings that can serve as a guide for
critiquing these SPM presentations.
