RECRUITING

Hippocampal and Frontoparietal Development and Inference

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The goal of this clinical trial is to test if an intervention used to manipulate memory and inference can improve our understanding of how brain development supports these abilities in healthy adolescent and adult volunteers. The main questions it aims to answer are: (1) Do hippocampus and ventromedial prefrontal cortex shift from forming simple memories for singular experiences to more complex memories that link numerous experiences together?; (2) Does an improved ability to retrieve prior memories in parietal cortex during new learning have consequences for how those memories are organized at different ages?; and (3) Does the emerging memory control supported by ventromedial prefrontal cortex development facilitate the formation of optimally-organized memory representations? Adolescent participants (13-18 years) will perform two experimental tasks during functional magnetic resonance imaging (fMRI) scanning at three timepoints (T1-T3), spaced 1.5 years apart. Researchers will compare behavioral and neuroimaging data to a separate group of adults (19-25 years) who will perform the task at a single timepoint (T1). The tasks and comparison groups will allow us to isolate the neural processes that support memory and inference behavior, and how these processes change with age.
