The objective of this study was to examine group differences in fear reactivity and stress psychophysiology in infancy among children classified as having CP with CU (CP + CU), CP without CU (CP only), or no CP in later childhood. No group differences were observed in children at 6 months of age. However, at 15 months of age children with later CP + CU displayed greater high-intensity fear behavior, higher pretask and overall cortisol levels, and lower levels of HP and RSA compared to children with CP only and children with no CP.
