Makes perfect sense! so responses here can be a consequence of failure of contingency detection rather than the dissociation of the response from its outcome representation (similar to our findings about reduced S–O knowledge leading to habit-like responses rather than action slips) 💡

Very cool paper! 🙌 Interesting that most participants accurately detected changes in contingency relationships, so the results are unrelated to understanding the task requirements

This article is now published in @plosone.org. journals.plos.org/plosone/arti... New analysis added: seemingly habitual responses are explained because contingency deg didn't work for some participants (in line with recent outcome dev results in our lab and in @clairegillan.bsky.social lab)
The degraded contingency test fails to detect habit induction in humans
In experimental psychology and behavioral neuroscience, habits are considered stimulus-response (S-R) associations formed through extended reward training. Accordingly, habits are assessed using one o...

The good news? If there’s more than one mechanism driving compulsive behaviour, there’s likely more than one way to intervene! We talk about this in our @cp-trendscognsci.bsky.social review @eikekofi.bsky.social @parnianrafei.bsky.social

Leveraging cognitive neuroscience for making and breaking real-world habits
Habits are the behavioral output of two brain systems. A stimulus–response (S–R) system
that encourages us to efficiently repeat well-practiced actions in familiar settings,
and a goal-directed system...

Very interesting findings that add relevant context to our results in this recent preprint (osf.io/preprints/ps...) about outcome devaluation protocol knowledge (lack thereof), which could be easily mistaken with "habitual responding"!

@kellydonegan.bsky.social will present "Compulsivity is associated with an increase in stimulus- response habit learning"📱,which we are 🤏 close to pre-printing. So 🙏 give us your thoughts and ideas!
