😍 Our latest is out now in @commspsychol.nature.com. 🤩 We show with Bayesian modelling and experimental manipulation of uncertainty that developmental differences in social influence depend on differences in the internal uncertainty people have about their choice doi.org/10.1038/s442...

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology
Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.

"Individual differences in speed–accuracy trade-off influence social decision-making in dyads" 🚨Our paper has been published in Proceedings of the Royal Society B doi.org/10.1098/rspb... w/ Alan Tump @alantump.bsky.social, Ralf Kurvers @ralfkurvers.bsky.social @royalsocietypublishing.org 1/ 🧵👇
Abstract: Speed–accuracy trade-offs are a fundamental aspect of decision-making, requiring individuals to balance collecting more information against making faster decisions. Although speed–accuracy trade-offs have been studied at the individual level, their role in human decision-making in social settings remains poorly understood—even though faster, and possibly more error-prone, decisions often have more social influence than slower decisions. We examined how individual differences in speed–accuracy trade-off preferences shape decision-making in pairs, using an interactive online experiment and drift–diffusion modelling. Participants first performed a perceptual task alone, allowing us to estimate their individual drift rates and decision thresholds, the key cognitive determinants of speed–accuracy trade-off preferences. They then performed the task in pairs, sharing decisions in real-time. Pair accuracy depended on the faster (and thus more error-prone) member, and not on the slower (but more accurate) member. Social decisions were not worse than individual ones because faster members increased their thresholds in the social condition and became more accurate, while slower members incorporated less social information. These findings show that individuals adjusted their social information use to the speed–accuracy trade-off preferences of their partners, highlighting the importance of such individual differences for understanding social behaviour.

Romanticisation of mental health problems in adolescence: what's the deal with that? 🌟 NEW PREPRINT by Awa Ndour and me 🌟 (Romanticise = to portray something as more desirable or positive than it really is) Brief summary below (🧵) osf.io/preprints/os... #PsychSciSky #DevPsychSky #ClinPsychSky
Romanticisation is the perception and portrayal of a phenomenon as more attractive, interesting, cool, profound or desirable than it really is. There are concerns that mental health problems are increasingly romanticised, particularly among adolescents, but there is limited research on this topic. This narrative review investigated: (1) what romanticisation is in the context of adolescent mental health problems, (2) why adolescents might romanticise mental health problems, (3) the implications of romanticising mental health problems in adolescence, and (4) what interventions might reduce this phenomenon. Sixty-one publications were reviewed, including qualitative and quantitative analyses, cross-sectional and longitudinal self-report studies and conceptual reviews. Most investigated romanticisation of mental health problems online. Identity formation, popular media influences and peer influences arose as potential explanatory factors. Negative outcomes to romanticisation were indicated
