Preregistration In Science

Making Science great again

Why is it important to preregister research studies? According to associate professor Matthias Mittner, at the research group for cognitive neurosciences at UiT the Arctic University of Norway, there are good reasons for doing this:

  1. You can get good feedback from reviewers on an early stage.
  2. You get a time stamp on your idea.
  3. The result is more trustworthy, and you avoid data drudging,  like p-fishing, or post hoc storytelling/HARKing (hypothesizing after the results are known).
  4. You also increase the credibility of the reports you produce.

Open Science, preregistration and mind-wandering

In this podcast episode of Open Science Talk, Matthias talks to us through his experience with the Open Science Framework(OSF), and how it has helped his projects.

One of them, a replication study on the increasing propensity to mind-wander by transcranial direct current stimulation, was mentioned in our podcast. But the result of the study was never mentioned.

The research groups findings show support against a stimulation effect on self‐reported mind‐wandering scores.

Here is their conclusion as written in their abstract on the published report:

“Finally, even when combining data from both the original and replication studies, we could not find evidence for an effect of anodal stimulation. Our results underline the importance of designing studies with sufficient power to detect evidence for or against behavioural effects of non‐invasive brain stimulation techniques, preferentially using robust Bayesian statistics in preregistered reports”.
