My research interests fall into three broad categories encompassing infant cognitive and social development, computational models of cognition and the use of computer games to collect rich data with high ecological validity.
My primary empirical work involves behavioural research with infants. My PhD investigated the earliest emergence of concepts and abstract reasoning in infancy. My post-doctoral work has looked at the statistical processes underlying language learning and how infants acquire a sense of time. Neural network models provide an excellent a framework for understanding learning and development. I am developing computational models of the various cognitive processes that I study. In addition, I will shortly be commencing a large scale survey of laughter in early childhood.
Finally, I develop computer game based testing as methodology for collecting rich and relevant data from a range of participants. In my PhD I wrote a 3D video game to test children’s category learning abilities. More recently, I have started an ambitious project to use smartphone games to track the cognitive and emotional affects of adult alcohol and drug use. See http://yourbrainondrugs.net/about

In my PhD, I studied the origins of concept formation in infancy. How do babies learn to find patterns and regularities in the world.. all these small furry animals are dogs, those ones are cats, this one specifically is Spot and this one Felix and collectively they're all pets. And they're also mammals, animals, things you might expect to meet in the home or see in cartoons. And having got all that sorted, you now have to learn to classify people, food, toys, furniture, vehicles, emotions, abstract relations. And all this while trying to learn a first language from scratch at the same. Gosh, it's complicated being a baby. No wonder they're bursting into tears all the time. You can learn more about it here.
