Practice effects occur for many cognitive tasks. They are observed not only between repeated tests, but also within sessions. They can confound the detection of treatment effects, even when compared with control groups. We present an approach to reduce the impact of within-session practice effects through inclusion and manipulation of time in linear mixed models. With an exemplary mental rotation ...
