Phenoscreen of NeuroDevelopment (PoND) Study Sarah Shivsankar and Emma Condy, Ph.D.

Introduction This study will use a Phenoscreen approach (Doyle et al., 2021) to study restricted and repetitive behaviors (RRBs) in toddlerhood. RRBs are seen in typical development and neurodevelopmental disorders (e.g., ASD). Effortful control, an element of temperament, is an early precursor to inhibition and emotion regulation which are thought to relate to RRB development. Using the Rothbart Temperament Scales and the RBS-EC, we will investigate how these two behaviors interact over time in early childhood.
