💥New paper out! Why do some people generalise threat more than others? We show that anxious people generalise more strongly, even after accounting for perceptual mistakes. A huge (!) thanks to @ondrejzika.bsky.social @nicoschuck.bsky.social and @bernhardspitzer.bsky.social

Anxiety is associated with increased generalisation of threat to similar stimuli. This paper dissociates perceptual mistakes from value generalisation and links stronger value-transfer to trait anxiety. @nicoschuck.bsky.social @ondrejzika.bsky.social www.nature.com/articles/s44...
