Eligibility criteria

For babies between 4 and 8 months of age, who haven't participated in the "Biologische Beweging Studie" (the Dutch version of the same experiment).

Duration 10 minutes

Unfortunately, we are not able to provide compensation for your participation, but we hope you and your child will have fun in helping science together!

What happens

In this study, your baby will see several short videos. First, we will either present a woman making hand gestures, such as playing peek-a-boo, or we will show rotating machine gears. Then, we will display two videos side by side that will show moving points. While in one of the videos the points resemble a person moving in the dark, in the other the points will be moving randomly. Which video will your baby prefer to look at more?

What we're studying

Human movements are an important source of social information for babies. Babies can distinguish human movements from non-human movements very early on, even if the movements are partially hidden or abstract. In this study, we want to see if babies can recognize human movements when they are represented by points corresponding to human joints moving in the dark. We are also trying to discover whether the context within which babies observe the moving point displays influences their ability. By answering these questions, we will be able to understand more about how infants’ social skills develop, in particular, to what extent the recognition and preference for human movement is automatic.
