| Abstract: | Child maltreatment is linked to distinct neurophysiological patterns and social‐emotional vulnerability. Relations among maltreatment, relative resting frontal alpha asymmetry, shyness, and psychopathology were examined prospectively. Adolescent girls (age 14–16) who experienced child maltreatment (N = 55) were compared to nonmaltreated controls (N = 25), and returned for 6‐ and 12‐month follow‐ups. Among participants exhibiting relative right frontal asymmetry, maltreated adolescents reported higher shyness than controls at Time 1. Low‐stable and high‐stable shyness trajectories were observed for maltreated participants. Compared to low shy, participants in high‐shy trajectory reported at Time 3: higher neuroticism and generalized anxiety; and lower extraversion if they also exhibited relative right frontal asymmetry. Thus, right frontal brain activity and shyness are involved in social‐emotional vulnerability of adolescents who experienced child maltreatment. |
