I had such a blast presenting the last project of my PhD for a flash talk and a poster at #Flux2025

Grey and white matter are not two separate tissues and we found that adversity is associated significantly differently with grey and white matter measures showing the importance of looking at both!

New paper for anyone working with data:
Better data viz - for free, in few clicks.

Below, all N = 111, M = 0.04, SD = 0.27.
One-sided t-tests vs. 0 yield: t(110) = 1.67, p = .049.

Use raincloud plots. Or risk wrong conclusions!
Plot w/ @jaspstats.bsky.social today!

Are you an international early career scholar considering spending time in the Netherlands? We likely have capacity to host a Marie Curie Fellow if you are interested. Our lab (lifespancognitivedynamics.com) works on modeling cognitive change in early or later life, at short and long timescales.

A pleasant surprise this morning to hear that I am one of the 2025 @fluxsociety.bsky.social Travel Award recipients.

Very much looking forward to the conference this September in Dublin, where I will present the first batch of results from our CODEC study (doi.org/10.1186/s403...)

📢 The SAA program is live at www.saa2025.com/Program and it’s almost too good to be true — but it is true!
So many incredible symposia, paper sessions, and posters to choose from that you’re guaranteed some FOMO! 🤯

Beautiful scenery last weekend during the #sallandtrail 50 miler #ultramarathon

result: 07:48:02, 6th overall!

Pretty stoked about it!

Tutorial on exploring ecological momentary assessment data is online at AMPPS, with:
- Accessible ways to visualize data for better understanding
- Models to get some first insights
- Further reading boxes for more advanced topics
- Reproducible pipeline you can run over your own data

honestly Current Biology has been the best place for me to get inspired. Badass, high quality science of all disciplines

The Raincloud Quartet (new pre-print)

All N = 111, M = 0.04, SD = 0.27.
One-sided t-tests vs. 0 yield: t(110) = 1.67, p = .049.

Only raincloud plots reveal the qualitative differences, preventing the drawing of inappropriate conclusions.

How did we create the quartet?
Where are data & code?
🧵👇
Four raincloud plots: a normal distribution, bimodal, skewed, and one riddled with outliers. Popular sample statistics are identical so that mere plotting of the identical means and confidence intervals would miss these qualitative differences. abstract of pre-print

with `ggrain` you can just select rain.side = 'l' | 'r'

we have a full tutorial here: www.njudd.com/raincloud-gg...

Looking for pointers on a publicly available longitudinal dataset with the following characteristics: 4 waves (or more), 4 cognitive domains/constructs/tests (or more), easy to access (no multimonth legal wrangling), N>100. Concrete suggestions much appreciated! #PsychSciSky

1/3 From now on its easy to import and analyze #ESM / #EMA m-Path data in R! Lara Navarrete and Koen Niemeijer created an amazing R package to:
- Import m-Path data in R
- Preprocess
- Check participant response behavior
- Transform variables
- Analyze
- Link data with other #ESM/#EMA R packages
