Effort choices are sensitive to prior learning Motivated behaviour relies on both learning and effort-based decision-making, yet these processes are often studied in isolation. We developed a novel paradigm combining probabilistic associative lear...

My first post into the bsky void, the first preprint of my PhD! A novel task to bridge learning and effort decision-making.

Of course, we find that effort choice is sensitive to prior learning, but this integration of beliefs into action is affected by anhedonia.

Code and data are available online (github.com/EddieBWXiao/...). Huge thanks to my amazing and dedicated supervisor, Noham, who has been a great mentor since my third year as an undergraduate.

This finding extended previous work on cognitive effort (doi.org/10.1016/j.co...), and we additionally quantified the subjective value of progress feedback. An exploratory analysis showed that people with higher social apathy scores were less progress-seeking 🤔 (3/3)

We developed the Ore Mining Task, where people made alternating button clicks to lift valuable minerals. Participants were offered two stations to work in, one with a progress bar and one without. Modelling suggested that people were willing to work more in exchange for progress feedback… (2/3)

My pre-PhD work with @noham-wolpe.bsky.social is finally out! doi.org/10.1037/mot0000411

How does progress feedback influence effort-based decision-making? Our study involved a novel effort manipulation designed for online testing and mouse-tracking. The results came with a twist on apathy… (🧵1/3)

🚨Thrilled to share a new paper on emotion ensemble processing in anxiety.

Threat biases arose in dual fashion, such that individuals with anxiety displayed:
• an attentional bias indicating threat avoidance
• a judgemental bias favouring threat

Neurochemical markers of uncertainty processing in humans How individuals process and respond to uncertainty has important implications for cognition and mental health. Here we use computational phenotyping to examine individualised 'uncertainty fingerprints...

New preprint alert! How do we process uncertainty, and how do neurometabolites shape this?🧠Here we combine computational modeling + 7T MRS to answer these questions: www.biorxiv.org/content/10.1...
