Key publications on child development from Dr Sam Wass and the BabyDevLab at the University of East London. Full, up-to-date publication lists are available on Google Scholar and Researchgate. Resources for researchers are also available, with articles on methods, analysis and the big picture. An overview of collaborators can be found here. A description of Sam’s current 5-year European Research Council Fellowship project, on how infants’ biological rhythms entrain to the social and physical environment during early life, can be found here.
How stress influences attention and learning in children
My research has investigated relationships between physiological stress during early child development. Recently, I have been working on new techniques to model how children’s stress states spontaneously fluctuate in real-world naturalistic settings.

How children’s stress, attention and learning are influenced by people around them
I investigate how stress and attention emerge as shared states during parent-child interaction by recording brain activity and physiology in parents and children concurrently during free-flowing interactions.

How children’s stress, attention and learning are influenced by their environment
These papers examine how noisy and unpredictable early-life environments can affect the early development of cognitive and affective control.

Attention and stress in atypical children
In addition to examining the relationship between physiological stress and attention in typical children, we also study atypical populations, such as children with ADHD and Rett Syndrome.
