The latest version of Sigmund, the #AI #research assistant, is able to fully control the #OpenSesame interface. This allows you to build #psychology experiments entirely through conversation. This is no AI slop, but real functionality with real benefits! Tutorial 👉 osdoc.cogsci.nl/4.1/tutorial...

We used a brain "pinging" again and found that distractor suppression is reactive rather than proactive, meaning attention is first drawn to the distractor before being suppressed.
Neural mechanisms of learned suppression uncovered by probing the hidden attentional priority map
Learned suppression of distractor locations in visual search emerges through reactive mechanisms that involve initial spatial selection prior to suppression.

Are humans really the only rational animals? Our NEW PAPER 🎉 out in @science.org suggests otherwise! In a large collaboration led with my joint first author @hanna-schleihauf.bsky.social, we show that “Chimpanzees rationally revise their beliefs” 🧵
Chimpanzees rationally revise their beliefs
The selective revision of beliefs in light of new evidence has been considered one of the hallmarks of human-level rationality. However, tests of this ability in other species are lacking. We examined...

Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
Concurrent selection of internal goals and external sensations during visual search
Internal and external selection processes can codevelop in time to yield efficient search behavior.
