Sarah Babkirk is a fifth year PhD candidate in behavioral and cognitive neuroscience at CUNY Graduate Center in New York City. The Association for Psychological Science Student Caucus (APSSC) Student Grant will be used to compensate children and families who participate in Sarah’s dissertation study examining the development of emotion regulation. This study integrates neural correlates, behavioral measures, and ecologically valid social context to identify core emotion regulation capacities in 5- to- 8- year olds. In particular, the late positive potential (LPP), a scalp-recorded event-related potential (ERP) has been shown to be related to ER capacity and positive mental health outcomes across the lifespan. This between-groups study will also systematically manipulate social context by introducing maternal emotional scaffolding to bootstrap child emotion regulation while ERPs are recorded. The outcomes of this project have to potential to establish support for the use of the LPP as a neurophysiological indicator of child emotion regulation and demonstrate that social context influences child regulatory success.
