Who Can Participate?
Parents and guardians of infants and toddlers between the ages of six and sixteen months are invited to take part by sending us a video or videos you have recorded of your little one. This is an online study but you will need to be logged in to Google Drive to upload your videos for us. This may be via a Gmail account or a university or work account that is linked to a Google Workspace or Suite (e.g. an or account).

If you have access to the internet, you can take part from home at a time that suits you. We are seeking videos of babies and toddlers taken in their own homes, videos which show them reaching for, holding, and using the objects and toys around them. Read on to find out how to participate.


We are researchers in the School of Psychology studying how infants use their hands.


We know that parents of babies and toddlers use their phones to take lots of videos of their children. These videos are not just a way to share your baby's development and the cute things they do with your friends and family. They are actually valuable scientific data! We encourage parents to think of themselves as "citizen scientists", documenting important information about children's development.

If you are the parent of a child between six and sixteen months of age (or have saved videos of your child when they were in this age range), we would be delighted if you shared your videos with us. We are specifically looking for videos in which babies and toddlers are using their hands, for example playing with toys or feeding themselves.

We have a couple of guidelines for videos. The best videos for our purposes will have the following features:
(1) there will be just one baby in the video, and the video will have been filmed in your home (sadly we cannot accept videos with more than one baby, or videos filmed in a public place).
(2) the baby will be in the centre of the screen, facing the camera.
(3) the baby will have at least two objects around them, that they can reach (or try to reach). These could be toys, household objects, or anything else your baby could touch or hold.

You do not need to film anything new for us but you are welcome to film something according to these guidelines if you like. Videos can be of any length but we suggest that they are no longer than 30 seconds because bigger files take a long time to upload. We include some stock images below, to give you an idea of the kind of camera angle and the kind of activities your recording might include

Parents must be over 18 to participate. After you read the information sheet at the link above, you can click "Next" at the bottom of the page to agree to take part in the research and to answer a few questions about you and your child. We will ask for your email address so we can send you a link to another form where you can upload between one and three videos of your child.
