1/6 Excited to launch my blog! First post: Using Bayesian hierarchical models to rescue "unreliable" cognitive tasks. The dot-probe task serves as my case study 🧠📊 cogpsychreserve.netlify.app/posts/dotprobe…

Hey researchers, bloggers, everyone interested in fertility data! We recently added lots of new data at Our World in Data on fertility rates, ages at childbirth, twin birth rates, birth seasonality, and more. Here's a thread of what you can find on the site! 🧵

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. 🧵

Want a simple illustration of how results can be incredibly sensitive in small samples? Here you go! This visualization provides raincloud plots with N=20 (on the left) & N=500 (right). There is no difference between the two conditions other than the N. Statistical power
