Development at the interface between the individual and the environment

How do infants begin to understand and interact with the world around them? Which are the critical cognitive and neural mechanisms at the side of the individual and how do these mechanisms act in concert with the experiences that young children gather in the interaction with their physical, social, and cultural environment? We investigate human development from a dynamic developmental systems perspective, aiming to understand the complex interplay between individual and environmental factors. Our research can roughly be sorted along three lines, (1) early (socio-)cognitive development, (2) neural learning mechanisms, as well as (3) early social and cultural learning.

Early (socio-)cognitive development

With behavioral, eye-tracking, and neurophysiological (EEG) Methods we investigate infants' early understanding about their social and physical environment. For example we investigate the principal mechanisms that drive human prosocial development, infants’ early normative understanding, as well as the development of early emerging concepts about the physical world.

Neuronal learning mechanisms

In electroencephalographic (EEG) studies we addresses how infants, children and adults sample novel information from their environment and build up lasting memories. Specifically, we are interested how neural mechanisms develop and change from infancy to adulthood. Our focus lies on neural oscillation, which form the bedrock of neural communication and learning processes. Finally, we use rhythmic visual stimulation methods to modify neural learning processes and thereby promote human learning.

Early social and cultural learning

Through behavioral measures we assess early interaction experiences that young children make in their social and cultural environment and how those shape early human development. For example, we observe, in standardized and ecological settings, how parents teach novel activities, transmit social values and how they guide their children's attention.
