General

My current research mainly focuses on children’s gestures and speech when they learn about Science & Technology tasks. Inspired by dynamic systems theory and ecological psychology, I research how children’s gestures and speech change over time, within a task. Furthermore, I investigate how learning emerges from children’s interactions with the environmental properties of a task. I research both individual and dyadic learning. I’m currently a PhD student and teacher at the University of Groningen.

Methods that I use include video-recording of children’s task performance and coding their gestures and speech, movement tracking using either video-recordings or motion trackers, and audio-recording. Analyses focus on non-linear development, such as Recurrence Quantification Analysis (RQA).
 
Other projects that I’m involved in are related to gesture-speech coupling in general, and to communication of deafblind children.
