Research

Our research focus is on cognitive and social-cognitive development in the first years after birth, with a particular interest in learning and memory.
These are some of the specific topics we are currently investigating:

Infants spend the majority of their time asleep. Nevertheless, surprisingly little was known about the effects of sleep on early learning and memory until recently. Some recent studies have shown that sleep supports memory functioning early in life already. Building on these findings we are investigating if sleep is relevant for selectivity in remembering and for qualitative changes in early memories.

The range of media targeted at children has increased rapidly over the last decades: Tablets, smartphones, television and other devices offer a range of different possibilities for viewing, interacting, and playing to younger and older children. The drawbacks and opportunities of media use in the first years of life are not completely understood. It is well established, however, that it is more difficult for infants to learn new behaviours from media compared to learning in real-life social interactions. We are examining which factors could support infants in transferring knowledge offered in media to the 3-D world.

Experiences made during the first years of life are thought to be crucial for long-term human development. If children grow up in stressful circumstances this can have consequences for their cognitive development, too. We are examining how potentially stressful life events are related to how flexibly infants and young children deal with requirements for behavioral change in learning tasks.

Pregnancy and birth bring with them many changes and challenges that can be stressful. Impaired maternal well-being can have consequences for infant behaviour and development. Recent studies suggest that maternal repetitive negative thinking could be a relevant underlying mechanism to explain relations between maternal mental health and infant development. We are aiming to investigate this possibility further and to identify suitable targets for interventions.

Past research has shown that infants effectively discriminate a range of different faces until about 6 months of age. From then, infants’ face processing skills increasingly reflect their everyday visual experiences and they become attuned to those types of faces (e.g., in terms of species, ethnicity) that they frequently see. We are studying this phenomenon of perceptual narrowing further and ask if infants with versus without siblings vary in their face processing of child faces over time.

Preschoolers often adapt their behavior to different situations and people. We are interested in the way they change their affect and behavior, when the perform different activities with different caregivers. We moreover strive to investigate whether different adults (for example mother and grandmother) behave differently with their child or grandchild, respectively.
