Abstract	Fixed stimulus presentation times pose several methodological problems for developmental functional magnetic resonance imaging (fMRI) studies that can be avoided by self-paced study designs. Yet, methodological issues of self-paced stimulus presentation for fMRI studies are largely understudied. Therefore, we compared sensitivity, reproducibility, and reliability of neural activation of a fixed and a self-paced design for an exact, non-symbolic addition paradigm in a sample of children aged 6-12 years. Both design types were comparable in sensitivity, and the self-paced design was superior in reproducibility and reliability. Therefore, self-paced study designs seem to be a valid option for developmental fMRI studies on higher cognition. (Orig.).
