💥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

In this project, we will measure people's sense of control and their need to exert control in individuals with #eatingdisorders (and #OCD) over a month, applying #computationalmodelling to explore how control-related processes change and persist over time ⏳ and how this relates to symptom severity 🧠

Excited to receive the @britishacademy.bsky.social's Early Career Researcher Seed Grant for our project “Understanding the dynamics of control in eating disorders” 🌀🌱 with @alexandrapike.bsky.social

Metabolic Contributions to Learning and Feeling: Why They Matter and How to Make the Most of Them

Thoroughly enjoyed writing a commentary on a great paper by @hugofleming.bsky.social et al for @biologicalpsych.bsky.social:GOS, focusing on how to further explore metabolic contributions to learning and feeling using real-time data and interventional designs:

In factor analysis, why does the commonly used CNG method nearly always land at 3 factors when applied to anx/depr/ocd scales?

TLDR: There tends to be one factor/component with a large eigenvalue. In these cases, almost inevitably and somewhat arbitrarily, the procedure selects 3 factors 👇

Why do some people feel a “not-quite-right” sensation before they pick their skin?

The first ever systematic review on interoception and skin-picking disorder explores how bodily cues and affective touch might help explain the urge.

Action repetition biases choice in context-dependent decision-making - Communications Psychology This study shows that decision biases previously attributed to value normalization (e.g. relative value learning or range normalization) are better explained by action repetition. Repeating an action ...

Very happy that this is out www.nature.com/articles/s44.... Together with @stefankiebel.bsky.social we show that decision biases in context-dependent decision making, previously attributed to different forms of value normalization, are very well explained by habit-like action repetition.

Out now in Translational Psychiatry! www.nature.com/articles/s41...

Impaired goal-directed planning in transdiagnostic compulsivity is explained by uncertainty about learned task structure Diminished use of goal-directed (“model-based”) decision-making is a hallmark of transdiagnostic compulsivity, promoting an over-reliance on inflexible and habitual behaviours. However, the origin of ...

Sookud and colleagues found that individuals with higher compulsivity and intrusive thoughts develop a less certain internal understanding of the external world, and this mediates the link between symptoms and goal-directed behaviors.

Really excited to have had the opportunity to write this article !

IU is one of my main research areas so I really enjoyed writing about this paper 😊

JOB 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...

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...

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)

Taken together, our results advance our understanding of the dynamics of fun in realistic environments. They also emphasize the importance of using realistic, game-like environments together with highly-controlled experiments to advance our theories of human motivation & learning.

Congrats Ondrej & failte to Eire ☘️

🚨 I am over the moon 🌓 to announce that I am joining University College Dublin @ucddublin.bsky.social as an Assistant Professor this fall to start the Uncertain Mind (UMI) lab 💫

I am looking for PhD/Postdoc candidates to join (more below 👇 ). Please RT as the deadline is pretty soon 🙏

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...

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

People higher in compulsivity made the most habit errors - suggesting stronger habit formation 🏋️‍♀️

… but so did younger adults, men & those with more education! Because habits aren’t 'bad'. They’re efficient ✅. Until they're not 🚧.

Time-dependent competition between goal-directed and habitual response preparation - Nature Human Behaviour Hardwick et al. show that habits in human behaviour consist of automatic preparation of an action in response to a trigger. Even though we can learn to control habits to perform different action respo...

Similar to the lab-based version, we found more habits following extended training. And this effect was time-dependent ⏱️, with habits being revealed when you have to act fast

Introducing ... 🥁🥁🥁... COGQUEST

Training habits = lots of trials + multiple in-lab visits. Burdensome & inaccessible 🥱🚫 That’s why we gamified a habit task via @clairegillan.bsky.social's Neureka app

1000 people trained habits over a week, while also reporting on their mental health. All without stepping foot inside the lab!

🚨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

New 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
