The Organization for Human Brain Mapping has established an award that recognizes the best replication study and highlights OHBM’s commitment to reproducibility in neuroimaging research and helps begin to reshape the incentives towards replication.
What is a Replication Study?
A replication study is a repetition of a published study procedure with minor changes to variables assumed not to be important for the measured phenomena (this depends on the experiment, but could include demographics, scanner model, visual stimuli delivery system, analysis strategy, etc.). Replication studies usually (but not always) have a larger sample size than the original study for appropriate statistical power, and are performed by a different team than the original study (but planning of a replication study can benefit from involvement of the original researchers). Even though minor changes between the original study and its replication are inevitable they should be minimized as much as possible.
What Makes a Good Replication Study?
A good replication study is a study that addresses an important topic for the neuroimaging community. The study needs to show highest standards of experimental design, data collection and statistical analysis. Openness of experimental procedures, pre-registration, data processing and statistical analyses as well as public availability of collected data also speak in favor of a good replication study. Authors should also show maturity and thoughtfulness when discussing results of the replication and should give the original authors an appropriate platform to comment on the replication. It is also worth noting that a good replication study does not necessarily have to show the same effect as the original study. Both “successful” and “unsuccessful” replication attempts will be considered for the award. Methodological replication as well as replications that are part of a larger study will also be considered for the award.
Studies can be nominated by their authors or third parties. Studies nominated in previous editions of the award cannot be nominated again unless they have been substantially revised.
Please submit your nomination here by Friday, January 10, 2020.
The recipient will receive a cash award of $2,000 USD along with an engraved plaque. Both are presented at the OHBM Annual Meeting being held June 25-29, 2020 in Montreal, Canada. The awardee will be given the opportunity to give a brief remark during the Annual Meeting.
