Now online at @NatMentHealth ✨✨ Leveraging a computational psychiatry approach, we found that #autism-related traits are specifically associated with reduced observational learning through reduced goal emulation.

Huge thanks to co-authors for endless brainstorming sessions to help make sense of this (messy) data: @QianyingWu1, @seokyoung_min, Weilun Ding, @jeffcockburn, and John O'Doherty. (8/n).

This work constitutes a proof-of-concept that, especially with large-scale online studies, heterogeneity should be embraced rather than ignored, though more work is needed to test and improve classification/clustering approaches and their relevance to psychopathology (7/n).

Finally, we provide some insights into the potential relevance of this classification to transdiagnostic symptom dimensions, with groups differing significantly along autism-related traits and trait anxiety, typically associated in the population (and in our sample). (6/n)

To examine heterogeneity, we classified participants into 5 groups based on which model explained each participant’s data best, rather than assuming a ‘best-model fits all’. We found that groups differed in all key behavioral signatures, thus validating our classification (5/n)

We then performed robust simulations and posterior predictive checks to ensure each model could be appropriately recovered and captured expected behavioral signatures in the data. (4/n)

We fit a set of 5 parsimonious models to the data to capture individual strategies: experiential learning (EL) only, observational learning (OL) only, fixed mixture, dynamic arbitration, and a baseline model containing non-learning heuristics. (3/n)

We first showed (and replicated) that participants’ behavior is a mixture of the two strategies, and varies with changes in uncertainty in the environment, consistent with theories of arbitration. Yet, we found huge individual differences that we wanted to further examine. (2/n)

A bit late on this, but our new paper is out in @NatureComms : In this study, we embraced the noisiness on large-scale online data to characterize heterogeneity in experiential vs observational learning strategies. (1/n).

Truly enjoyed my first @AutismINSAR conference #INSAR2024 - such an inspiring mix of basic science, clinical research and amplifying autistic voices!.If you are interested in the heterogeneity of autism, consider submitting a paper to this upcoming @PNeuroscience special issue 👇.
