It's becoming clear that running online studies needs yet another set of skills (on top of java, Qualtrics, etc.) - being up-to-date on the latest GPT capabilities and how to detect their use. It's an arms race so this extra skill set shouldn't be underestimated.

Amazon Mechanical Turk (AMT/Mturk) will be shut down as of September 30th. This marks the end of an era. It laid the foundation to the now ubiquitous use of online studies in the psychological and social sciences. It also became too unreliable in recent years. Still, I'm going to miss it.

Have you ever felt like something was missing from your #fmri results? Have you been worried about potential reproducibility issues? Well, this new @natmethods.nature.com article with 40+ coauthors shows how the simple change to transparent thresholding helps both. Go Figure! rdcu.be/B4tikBETdQZa
A comparison of old and new thresholding approaches for fMRI data. The newer, transparent thresholding allows for interpreting context, more complete modeling, a reduction of biases and an increase in meaningful content. This all leads to more accurate interpretations and improved reproducibility evaluations.

I have been meaning to write a post about a preprint that I'm pretty excited about: www.biorxiv.org/content/10.6... In neuroscience we often assume that we can learn something general about “the brain” using different species. But is this true? Do monkeys even see the world the way we do?
