WHALE Pilot Study
Exposure to early adversity (EA) profoundly increases risk for psychopathology, making exposure to EA a central public health concern. The profound and long-lasting effect that EA has on mental health makes it an important area of inquiry for prevention and intervention efforts. The pilot study assessed deprivation, threat and behavioral performance in children between 4 and 7 years old. Our recruitment strategy is aimed at identifying children with a range of exposure to maltreatment, neglect, and learning opportunities. The pilot study recruited 65 children to complete behavioral tasks (fear conditioning, working memory task, cognitive control task, reward task). Parents completed a diagnostic structured interview to assess psychopathology in the child. Children completed interviews assessing exposure to violence and neglect. To date, we have found evidence for differential roles of deprivation, threat, and parent emotion socialization as predicting child performance in the current study. We also found that fear learning can predict risk for PTSD symptoms following Hurricane Florence, a traumatic event for some families in the sample.

This study investigates how different early life experiences impact brain development. We are seeking children from diverse backgrounds to better understand how a child’s environment can shape the brain. The study consists of three visits. For the first visit, research assistants from our lab will visit participants at their home. For the second visit, families will come to our laboratory on the UNC campus. For the final visit, children will complete an MRI scan at UNC that will take no more than one hour. Participants will be compensated for their time for all visits.
We are looking for participants within the age range of 4-6. If you are interested in participating in this study, please contact us.
