Our PhD student Petronela Sušienková recently returned from a several-month internship at Finland’s second largest university – the University of Turku. She collaborated on the FinnBrain longitudinal cohort study, where she had the opportunity to familiarize herself with a multidisciplinary approach to longitudinal research and the measurement of biological, neuroimaging, behavioral, and psychological variables during child development. In her main project, she worked on preprocessing and analyzing heart rate variability data within a complex task focused on reading and self-regulation in 5th-grade participants.
