We may appear more aloof or be more impatient, may self-isolate, have more typos, may freeze or overwork to numb the pain, or find fear, memory, or hope in unexpected moments.

- Reposted by Parnian RafeiJOB ALERT: I am offering a 4-year funded PhD opportunity. The position is specifically linked to the project “Assessing the balance between goal-directed and habitual processing through the course of learning". The project is about learning habits and include eye tracking and pupillometry...
- Reposted by Parnian Rafei🚨 New publication: How to improve conceptual clarity in psychological science? Thrilled to see this article with @ruimata.bsky.social out. We discuss how LLMs can be leveraged to map, clarify, and generate psychological measures and constructs. Open access article: doi.org/10.1177/0963...
- Reposted by Parnian RafeiLooks interesting! We have been facing this exact issue - finding big inconsistencies across different LLMs rating the same text.
- 🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**. Paper: arxiv.org/pdf/2509.08825
- Reposted by Parnian RafeiThis 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)
- Reposted by Parnian RafeiExcited to share this new preprint on the Predictive Modelling of Depression Treatment Response using Individual Symptoms and Latent Factors with @clairegillan.bsky.social fresh up on @medrxivpreprint.bsky.social www.medrxiv.org/content/10.1...
- Reposted by Parnian RafeiOut today in Molecular Psychiatry our paper on multiverse computational factor modeling (i.e. a lotta lotta factor analyses). Thread below for the full rundown. Last PhD paper from @celinef.bsky.social YOU'RE FREE!! www.nature.com/articles/s41...
- Interested in the structure of psychopathology? We have a new preprint for you osf.io/preprints/ps... led by @celinef.bsky.social "Mechanistic arbitration between candidate dimensions of psychopathology"
- Reposted by Parnian RafeiPhotovoice Exhibition 29th - 31st October at Trinity Business school led by Dr. Claire Howlin. ‘How Music and Arts Support Neurodiversity’ will showcase photos and stories from neurodivergent adults about how creativity helps them thrive. Join us for the LAUNCH Oct 30th @dancingresearch.bsky.social

- Reposted by Parnian RafeiHey everybody! @drjuliawester.bsky.social and I have a new paper! We surveyed over 800 scientists, science communicators, and science educators who use social media. Conclusion: Scientists no longer find Twitter useful or pleasant, and many have switched to Bluesky! 🧪🌎🦑 doi.org/10.1093/icb/...
- Reposted by Parnian RafeiNew preprint from the lab on habit learning in compulsivity from the fantastic @kellydonegan.bsky.social! ✅ N=1000, ✅ pre-registered, ✅ within-person crossover design...we study individual differences in habit learning using the Neureka App
- 🚨PREPRINT ALERT🚨 Why do some people get stuck doing things that no longer make sense, or are even harmful? Our new study shows compulsivity isn’t just about weakened goal-directed control; people high in compulsivity also form stronger habits 📄: osf.io/preprints/ps... #PaperFairy #Habits #CogSci

- Reposted by Parnian RafeiNew preprint! Habits should get stronger with more practice, right? Well, this crucial result has been difficult to reproduce in human labs. In an instant classic, de Wit (2018) showed 5 failures in obtaining more evidence of habits in conditions with more training -as compared to little trained
- Reposted by Parnian RafeiIn February 2024, I wrote Scientific Reports about a published meta-analysis claiming that mindfulness interventions affect neural plasticity, 'cementing the neuropsychological basis of mindfulness-based interventions'. The paper was retracted yesterday—here a little summary of the process.🧵
- Reposted by Parnian RafeiYou happen to be at #CPConf2025 and interested in habitual processes and how they contribute to compulsivity? We've gathered data from 180 individuals across three different compulsion types including phone-checking (not reflected in the DSM!). Come visit me at poster 2.46!
- Reposted by Parnian RafeiExperimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
- Reposted by Parnian Rafei@glassybrain.bsky.social (Vanessa Teckentrup) will present "Understanding habitual properties of compulsivity using moment-to-moment experience sampling in daily life" with 6 weeks of EMA data tracking OCD, Binge-Eating and Phone-checking compulsions!📱https://osf.io/preprints/psyarxiv/yvhua_v1
- Reposted by Parnian Rafei@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!
- 🚨 New paper alert! Do time constraints reveal habitual behaviour? 🤔 We directly compared two major paradigms in the habit research field (Outcome Devaluation vs Response Remapping) under identical training and forced-response conditions 🧠 ⏲️ ⌨️ preprint: osf.io/preprints/ps...
- We observed: same S–R–O training, opposite habit expression patterns between paradigms! 🤯 habitual responses increased with more time in Outcome Devaluation – Remapping replicated classic findings: habits peaked under time pressure and faded with time 👇 www.nature.com/articles/s41...
- We argue that these tasks probe distinct cognitive processes: 🔁 Response Remapping → automatic response preparation 🛑 Outcome Devaluation → response inhibition (& S–O knowledge!) (lab-developed) #Habits aren’t one thing 👏 they're task-, context-, and process-dependent! www.nature.com/articles/s41...
