Excited to share that I’ll be starting my PhD in Clinical Psychology at @umassamherst.bsky.social, joining @katieleedg.bsky.social's lab! Grateful for the support from all my mentors. Also thrilled to announce that I was nominated for and have been awarded the Spaulding Smith Fellowship!

Huge thanks to Prof. Jutta Joormann and collaborators! I am grateful to the three reviewers who have offered very constructive feedback that has improved the manuscript!

This has broader implications beyond ER for how we study flexibility in behavior, cognition, and physiology. Using variability as a stand-in for flexibility can be misleading if context isn't modeled simultaneously. Context is the 🔑

Across daily diary and EMA designs, we used the Bray-Curtis dissimilarity index to directly assess ER–context covariation. Contrary to the assumption that variability is good, switching strategies predicted higher distress and psychopathology when the context was stable.

Most research on emotion regulation (ER) flexibility doesn't directly measure context. It just assumes that variability in ER strategies reflects flexibility. But is that actually true?

📢 New Publication Alert at JoPaCS! Many studies use variability as a proxy for flexibility across domains. Using emotion regulation as an example, we show that variability decoupled from context can be harmful volatility. Variability ≠ Flexibility. 🧵 doi.org/10.1037/abn0...

I will be sharing some exciting findings on how behavioral emotion regulation strategies are related to regulation motives and motive satisfaction at the symposium “To Strategies and Beyond!” on Friday morning. If you’re at SAS, I hope to see you there! (2/2)

Loneliness modulates social threat detection in daily life - Communications Psychology Using ecological momentary assessment and multilevel time-series models, we quantify loneliness inertia and its links to perceived social threat and social behavior, identifying dynamic patterns that ...

New paper led by SJ Shao in @commspsychol.nature.com. Across 20 days of EMA (5x daily), momentary loneliness prospectively predicted heightened social threat perception and social withdrawal. Trait loneliness amplified loneliness–rejection coupling and social disengagement @emoriebeck.bsky.social

Thrilled that this first empirical paper out of the lab is posted, led by Sandarsh Pandey, asking:

Depression (and other internalizing disorders) involve profound changes to sense of self. How can we study these differences using rigorous decision-making methods?

We present our new preprint titled "Large Language Model Hacking: Quantifying the Hidden Risks of Using LLMs for Text Annotation".
We quantify LLM hacking risk through systematic replication of 37 diverse computational social science annotation tasks.
For these tasks, we use a combined set of 2,361 realistic hypotheses that researchers might test using these annotations.
Then, we collect 13 million LLM annotations across plausible LLM configurations.
These annotations feed into 1.4 million regressions testing the hypotheses. 
For a hypothesis with no true effect (ground truth $p > 0.05$), different LLM configurations yield conflicting conclusions.
Checkmarks indicate correct statistical conclusions matching ground truth; crosses indicate LLM hacking -- incorrect conclusions due to annotation errors.
Across all experiments, LLM hacking occurs in 31-50\% of cases even with highly capable models.
Since minor configuration changes can flip scientific conclusions, from correct to incorrect, LLM hacking can be exploited to present anything as statistically significant.

🚨 New paper alert 🚨 Using LLMs as data annotators, you can produce any scientific result you want. We call this **LLM Hacking**.
