Hi @PerPalmgren ,
It's an effect size measure described in this paper and as implemented in the afex R-package. This effect size takes into account the other terms in the specified model (including interactions), and seems to be the recommended effect size for repeated measures ANOVA because it generalized better across studies.
Kind regards,
Johnny
