Am Wochenende hat das @dgps.bsky.social Projekt zur Einheit und Vielfalt der Psychologie in Berlin getagt - es war eine tolle und intensive Zeit im Haus der Psychologie, mit Besuch der Geschäftsstelle und vielen neuen Ideen und Aha Momenten. Bin gespannt, was uns im Herbst in Göttingen erwartet!
Spent the weekend in Berlin locked into some incredible, active debates with the #DGPs young members project, followed by good food and even better company. A truly rich community that I am glad to be a part of! @dgps.bsky.social @mfjsperl.bsky.social @evagorbanenko.bsky.social
Great apes may have been laughing with a similar rhythm to modern humans for at least 15 million years, suggests a study in Communications Biology. The findings also suggest that laughter has become faster, more variable, and increasingly influenced by the situation it occurs in. #evosky 🌎🧪
Rhythm and timing in laughter reveal that human vocal plasticity falls on a hominid continuum - Communications Biology
Comparative analysis of laughter rhythm across all extant great apes reveals that isochrony is ancestral to hominids, with tempo, variability, and context-sensitivity increasing progressively toward humans, tracing a continuum of vocal plasticity.

I spent the last month obsessed with finding colors that can't be displayed on a conventional screen. This is what I found. moultano.wordpress.com/2026/06/19/w...

A recent study claimed that because we have similar structures of colour experience, these similar structures point to us all seeing the same colours. | https://bit.ly/4eTUwm7 Philosopher Keith Allen disagrees; even one instance of difference in a structure changes the relationships throughout it.
Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq

#30DayChartChallenge Day 5 - experimental I have always loved Florence Nightingale's rose diagram, doubly so since reading @infowetrust.com 's book. This diagram shows all ranked games within each category of @boardgamegeek.com, as well as top 500 & 100. Done in #rstats: github.com/drjohnrussel...
Congratulations to Ian Thornton and colleagues who published their Mainz-Linez illusion in i-Perception (@pec-ipe.bsky.social): the red dots appears to wave left and right when one looks at one of the black dots, but they actually move straight journals.sagepub.com/doi/10.1177/...
Mammals have hundreds of joints and muscles. Controlling them individually would be nearly impossible. How does the nervous system organize such complexity into coherent actions? Our new study explores this question through a natural behavior: jumping.

Short trip to the world's largest computer museum! 🖥️✨ Our department visited the HNF. We covered everything from clay tablets to quantum computing. Thanks to @karolinem.bsky.social for organizing! 👏 Our heads are spinning with ideas on where to explore next.💡 #HNF #ComputerHistory
🧠 Mit dem @dgps.bsky.social JuMi-Projekt durften wir zu Gast an der @unileipzig.bsky.social sein. 🤩 Highlights: Führung durch den Wundt-Raum mit Erich Schröger & Austausch mit Cornelia Exner. 🤩 DANKE an @evalottabrakemeier.bsky.social und an @lubaumgaertner.bsky.social für den wunderbaren Empfang! 😊
Today was the last exam for our first semester students 😉 and this is what they got. Thanks for a great teaching experience!
The strongest version of this illusion I’ve seen! Absolute head-wrecker!
2026 starts with curiosity! 🌍🐾 The first #Behaviour issue is now live: from cooperative fish and dog “smiles” 🐶 to humans in urban spaces 🏙️ – diverse species, methods & shared insights. Explore the full issue: brill.com/view/journal...
Arrived in Leipzig with @evagorbanenko.bsky.social 😌 Looking forward to the second meeting of the #DGPs young members project today!☀️
Still my favourite book for a conceptual understanding of the formal principles behind multivariate models! Great for students without extensive mathematical training (e.g. psychology majors). 📐 "The Geometry of Multivariate Statistics" by Thomas D. Wickens www.taylorfrancis.com/books/mono/1...

Happy about our new paper with Anna Pöker, @janpdehaan.bsky.social and @frankeggert.bsky.social Applying a mathematical model from behavioural ecology to an interesting field context. 🐦 Open Access available at Behaviour: brill.com/view/journal... @ipmb-tubs.bsky.social
👀 Humans scan their environment in everyday life – but how much does context matter? A study observed 45 people in three urban spots: library, study house and refectory. Scanning was highest in the refectory, lowest in the library. @janpdehaan.bsky.social @frankeggert.bsky.social
“A bird with a 10-gram brain is doing pretty much the same as a chimp with a 400-gram brain,” said Onur Güntürkün, who studies brain structures at Ruhr University Bochum in Germany. “How is it possible?”
Intelligence Evolved at Least Twice in Vertebrate Animals | Quanta Magazine
Complex neural circuits likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.
