Wrote for @psyche.co about disinhibition – the trait that brings chaos and frustration, but can also (sometimes) spark charm and boldness. Check it out!

Hey #SRP2025! Curious about how context shapes impulsive action and inaction in daily life? Come chat with me about our findings!

Eg, if someone always has low values for emotion and impulsivity, with a person-specific cutoff of 85%, they would still have 15% “intense” values even though they never reported truly intense emotion/impulsivity.

It would also be cool to look at different thresholds for emotion and impulsivity.

Thank you! In our exploratory analyses in the first sample (the other five were preregistered), we tried person-specific thresholds but the direction of correlations was reversed. Person-specific cutoffs remove individual differences and the core question here is an individual differences one.

Co-occurring and covarying are different things. Nice to see others taking up this position. Super cool proof-of-concept with emotional impulsivity from @jananmost.bsky.social, @drsarahsperry.bsky.social, @kevinmking.bsky.social, and @aidangcw.bsky.social.

These findings have implications for the measurement of momentary urgency, and potentially for the articulation of other intense and dynamic events in the moment, such as binge drinking, suicidality, and reactivity. 11/n

Our results (summarized in the table below) suggest that the cooccurrence of intense instances of emotion and impulsivity was more strongly associated with trait scores of urgency and impulsivity relative to the traditional emotion-impulsivity covariance approach. 10/n

With ecological momentary assessment data from five preregistered samples and one exploratory sample, we proposed, and found support for, an alternative approach to more adequately capture urgency in the moment. 9/n

Would we really want to say that Person A was highly urgent and Person B was not? 8/n

In contrast, take Person B, whose reports of emotion and impulsivity are highly variable. Although they often report intense emotion and impulsivity that frequently cooccur, due to the irregularity of scores, they would have a relatively weaker emotion-impulsivity correlation. 7/n

Take Person A, whose reports of momentary impulsivity and emotion always hover in the low range near zero. To the extent that they fluctuate together, this person would have a strong covariance of emotion and impulsivity even though their reports never enter the intense range. 6/n

Let’s look at an example in the figure below. 5/n

More recent work studying urgency in the moment as the covariation of emotion and impulsivity has largely found small, nonsignificant associations with trait scores of urgency. Why might that be? 4/n

Urgency is a facet of impulsivity defined as the tendency to engage in rash action when experiencing strong emotions. Although urgency is defined as a dynamic, if-then process, the bulk of past work has used cross-sectional dispositional measures to study urgency. 3/n

Data from 1,186 participants across six independent samples suggested that the cooccurrence of intense instances of momentary emotion and impulsivity may be a better articulation of momentary urgency than the commonly used emotion-impulsivity covariation approach. 2/n

What is urgency and how should we best assess it in the moment? A thread 🧵 1/n

Hey folks! I'll be teaching two workshops in May on Structural Equation Modeling!

One course is introductory (May 7-9): smart-workshops.com/intro-sem-info

The other is on longitudinal models (May 14-16): smart-workshops.com/long-sem-info

🙏Please RT and share! 🙏

Let met tell you more...

Very excited to share our new paper, “Additive and Interactive Relations of Personality and Cognition with Externalizing Behaviors,” now accepted at Clinical Psych Science!

Thank you!

Huge thanks to my collaborators (@vizecolin.bsky.social, @siennarose.bsky.social, @whitneyringwald.bsky.social & @aidangcw.bsky.social) for all their help, support, and mostly, their patience.

For associations between individual HiTOP-PRO scales (there's 87 of them!) and daily experiences and behaviors check out the preprint!

The HiTOP-PRO domains correlated with individual differences in daily outcomes as expected, with overall positive correlations with negative affect and stress, and negative links with positive affect, energy, and sleep quality. Associations with social interaction outcomes were less robust.

We also see the emergence of new factors, like Grandiosity/Dominance, capturing experiences of well-being, domineering, and exhibitionism, and Rarity/Psychosis, marked by psychosis-like and rare experiences.

There are some key departures, mainly for historically understudied constructs like anankastia, eating problems, and grandiosity.

We see individual factors for Eating and Sexual Problems, perhaps due to measurement density, raising questions about the utility of representing such narrow factors.
