Stoked for my first APS #APS24SF! I'll be presenting on our InteractionPoweR #rstats package in an invited session on sample size planning!

Check our latest work where we assess the reliability of longitudinal MRI based data and the effect of follow-up time, number of observations, sample characteristics, and preprocessing pipeline biorxiv.org/content/10.110…

Does anyone know - what was the first study of individual differences that used an fMRI task?

We had the less common experience of going on the academic job market as couple. Tayler Sheahan and I wrote some reflections and advice about how we once again navigated our "two body problem". Hope it's helpful! davidbaranger.com/2024/08/06/nav…

Spin tests and such are great if you're comparing brain maps of distributions (mean/variance/etc). But if the maps are from regressions - use permutations!! Better error control, and can be applied to any measure type (volume, connectivity, white matter), not just the surface.

I've gotten multiple questions about how to visualize white matter tracts with the ABCD, but I don't think there's an easy way. Is it time for a ggsegAtlasTrack?

🔬The Sheahan Lab at MCW is looking for a research technician! This position is great for someone interested in gaining more neuroscience experience in the realm of itch/pain prior to applying for graduate or medical school. Please share! More info here: careers.peopleclick.com/careerscp/clie…

Woo another fun collab in the books! Enjoyed getting comfortable with multilevel log-linear models for this one.

Excited to share that this manuscript has now been published Nature Mental Health! nature.com/articles/s4422…

Remember back in 2022, when we didn't need to worry about a 2nd Trump Presidency, but were concerned about how many participants it would take to map links between personality & brain activity? (cf work by Scott Marek & Nico Dosenbach) We have good news 👇 nature.com/articles/s4200…

Question for my fellow task #fMRI folks: A frequent assumption I see (including in my own work) is that regions that are the most 'activated' in a contrast will also show the largest associations with individual differences. Is there any empirical work showing this is the case?

I'm shutting down PsyArXiv bot v2 until further notice. You can still get #Psyarxiv notifications on Bluesky.
