The Baby Laughter project

Main Project Information
Goal Help researchers understand what makes babies laugh.
Task Submit simple field report describing how you made a baby laugh!
Where Online only

Psychologists at Birkbeck Babylab wants to know what makes babies laugh. We think babies are going to be laughing at things that they are just starting to understand. (Once you know that dogs are supposed to go ‘woof’, a dog that goes ‘miaow’ is only going to be hilarious.) With enough detailed observations from enough babies at different ages we can paint a cheerful picture of what they understand at different ages.

So if you’ve made a baby laugh recently we’d like to hear about it. If you haven’t made a baby laugh recently, go and find one and get to work. It's fun but it's also science!
