On a step-by-step basis, we take the reader through all important aspects of study design – including the specification of hypotheses, sampling plan, analysis plan, and preprocessing pipeline – and thus provide guidance in planning a state-of-the-art fNIRS study. 2/7
To support researchers, we developed the "Preregistration for fNIRS Research (PRE-fNIRS) Template", adapting the established PRP-QUANT towards fNIRS research-specific needs and adding examples for fNIRS-specific items. 3/7
Lastly, anyone who sees room for further improvement of PRE-fNIRS (version 1), you are welcome to make suggestions to an open document that we created for feedback that we will consider for any future version. 7/7
