JASP Raincloud plots! More transparency, clearer patterns, better science. New BRM paper by @vlott.bsky.social, @donvdbergh.bsky.social, @fbartos.bsky.social, @njudd.com, @jordyvanlangen.bsky.social, @lukekorthals.bsky.social, @rogierk.bsky.social, @ejwagenmakers.bsky.social et al.

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!

Abstract of the linked article

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!

Flux Trainee Spotlight: Jordy van Langen - Flux Society

I was allowed to introduce myself in the
@fluxsociety.bsky.social

'spotlight' series, looking forward to the conference!

Just submitted my first individual peer-review, a daunting task, but glad that I did it! Thanks for earlier mentoring @coolenilse.bsky.social @rogierk.bsky.social

presenting a poster

Presenting and discussing our CODEC project at #saa2025 @ambulatory-assessment.org in beautiful #Leuven

It was super fun to showcase and discuss some of the first results from our CODEC project with attendees at the #wearables #biomarkers symposium yesterday!

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...)

Looking forward to showcase the first results of our CODEC project on all things EMA measurement of cognitive variability in children
@saa2025leuven.bsky.social
@ambulatory-assessment.org

I'll present during poster session 1 on May 26th!

Are you doing EMA research and wonder how to go about it? In recent work we've adressed some open questions and challenges, here is a brief summary of papers and materials.

Pretty stoked about it!

our R package github.com/njudd/ggrain just hit 30K downloads, very happy to see the uptake and its utility in the scientific community over the past two years @njudd.com @rogierk.bsky.social @micahgallen.com

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

I highly recommend the eScience fellowship - it has put me in touch with some very cool (& inspiring) people in the Open Software space!

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.

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?

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

what a great tutorial Vincent, thanks from me and all the raincloud plot authors!

Don´t plot means & confidence intervals alone; your data is more than that! With easy raincloud plots in JASP you get the full picture and can draw better conclusions.

Hot off the press, my latest paper with @rogierk.bsky.social

Integrating stereotypes and factual evidence in interpersonal communication - npj Science of Learning npj Science of Learning - Integrating stereotypes and factual evidence in interpersonal communication

The study used a simple age stereotype to show that interacting with others from a young age teaches us how to quickly overcome stereotypes.

Big thanks to Saskia Koch (not on Twitter) for leading this work.

We had a blast working with @louischarron.bsky.social‬ and his team, who produced this incredible video showcasing our latest study 🎥

Stereotypes often fail to capture a person’s actual qualities. So, what helps us move beyond them in social interactions?
