BabyX is an interactive AI model of an 18 month old.
It was originally launched in 2013, by then Auckland University researcher Mark Sagar.
Over the last 10 years it's been developed and improved, to the point it's now suitable for academic research into early childhood development
It allows researchers to do work that would be impossible or unethical on real human participants.
University of Auckland psychologist Florian Bednarski is taking advantage of those possibilities to conduct groundbreaking research.
