🚨 Now out in @jamapsychiatry.com 🚨 Are people with depression less responsive to rewards on social media, just like in the lab? Actually…quite the opposite! 🧵 📄 Read the paper here: jamanetwork.com/journals/jam...

We also applied a transdiagnostic approach on dataset 3, and found a double dissociation: 👍 reinforcement tendency was specifically linked to anxious-depression 🤳 behavioral persistence (a measure of posting habits) was specifically linked to compulsivity

We also applied a transdiagnostic approach on dataset 3, and found a double dissociation: 👍 reinforcement tendency was specifically linked to anxious-depression 🤳 behavioral persistence (a measure of posting habits) was specifically linked to compulsivity

Altogether, the findings: ✅ highlight potential mechanisms linking social media use to mental health ✅ illustrate the importance of studying real-world behavior

The main finding: across all datasets, people with depressive psychopathology were❗️more❗️likely to be reinforced by likes This contrasts with lab findings of blunted sensitivity to rewards in depression

This suggests the link between depression and reinforcement learning might look very different in the real world, where personally meaningful, often social rewards motivate our behavior

There is a lot of concern about the impact of social media use on mental health, yet few studies examine psychological mechanisms using objective data. At the same time, computational psychiatry studies cognitive mechanisms of mental health, but the evidence largely comes from artificial tasks.

We set out to address both of these limitations with a simple idea: using social media to study the link between reinforcement learning and depression Across 3 Twitter datasets, we defined a behavioral signature of RL – reinforcement tendency – as the effect of yesterday's likes on today's posts

🚨 New preprint 🚨 Across 3 experiments (n = 3,285), we found that interacting with sycophantic (or overly agreeable) AI chatbots entrenched attitudes and led to inflated self-perceptions. Yet, people preferred sycophantic chatbots and viewed them as unbiased! osf.io/preprints/ps... Thread 🧵

I strongly believe modeling behavior will be critical for understanding mental health well enough to develop new interventions, but the gap between task-based and naturalistic behavior is MASSIVE. Some great ideas here for bridging that gap!

Such an important topic: computational psychiatry at the nexus of lab-based understanding (eg of reinforcement learning and mood) and measures of real-world behavior and mental health conditions. (Scroll to the bottom for a link open to all).

Some to-dos for the field: - identify amenable types of real-world data - integrate them into data-collection pipelines alongside lab-based tasks - assess links to mental health - assess lab-based versus real-world convergent validity of parameters - expand models to accommodate real-world data

View full thread

Finally, we explore opportunities: 👍 Testing the generalizability of in-lab computational psychiatry findings to every-day life 👍 Incorporating linguistic behavior into cognitive models using LLMs (see figure)

…and challenges of this approach: ⚠️ Noisy data ⚠️ Analytical complexity ⚠️ Data collection burden ⚠️ Ethical considerations It remains to be seen whether real-world data can better computational psychiatry.

We review recent studies that probe cognition using real-world behavior, primarily in a reinforcement learning framework. Some of these have uncovered novel links to mental health (e.g. linking depression to blunted reactivity to positive prediction errors, or higher sensitivity to social rewards)

Computational psychiatry often relies on behavior in cognitive tasks, which are simpler, less engaging and often less social than real-world environments. By contrast, real-world data have intrinsic ecological validity and allow the continuous assessment of cognition and its variation over time.

By real-world data we mean any data that reflect a person’s every-day behavior. We distinguish 3 types: - experience sampling data (active, self-report) - passive sensing data (e.g. geolocation, physiology, social proximity) - digital-behavior data (e.g. social media, texting, phone/app navigation)

🚨 New Preprint 🚨 Prolonged Isolation is associated with an increased behavioural sensitivity to ‘Likes’ on social media. 🧵 Social media rewards are inherently social—but does posting change during social isolation, when in-person social rewards are limited? It turns out, yes!
