The present study tested C-section and vaginally born adults on six tasks: a visual search task, the Attention Network Task, the Sustained Attention to Response Task, the Stroop Task, the Trail Making Test, and an n-back task. Adults born via C-section were less accurate on target-absent conditions in the visual search task. No other tests showed significant differences based on birth method. Additionally, whole-brain voxel-based morphometry analysis was conducted on the anatomical magnetic resonance imaging data of adults to identify potential effects of C-section birth on cortical grey-matter integrity.
