Not a co-author, but a major influence -- big thanks to @dominikdeffner.bsky.social et al., whose prior modelling work and shared GitHub repo were foundational to this study:

Overall, our study shows how computational modelling can link observed behaviour to hidden cognitive mechanisms, and probe their generalisability -- we hope this encourages wider use of these approaches in animal cognition research! 🌐📝⚙️🧠

Using cognitive model estimates, we ran simulations where material rewards varied. Payoff structure -- not (dis)satisfaction -- drove social material choice. But bigger rewards didn’t mean more copying. So, preliminary insights into how material-use strategies may generalise e.g., in tool use.

We link males' material choices to two asocial and two social latent learning parameters -- their decisions are dynamic! -- to provide the first formal mechanistic evidence for the cognitive basis of birds’ nest building ⚙️🧠

Zebbie nest-builders seem to *copy-if-dissatisfied* with prior material-experience, particularly at 1st choice -- this suggests they recognise the utility of social information.
