Age differences in electrocortical reactivity to fearful faces following aversive conditioning in youth.

•We tested an aversive conditioning (AC) model for youth’s attention bias development.•Facilitated attention was assessed using the late positive potential (LPP).•AC resulted in less attention (smaller LPP) to fear faces among younger children.•AC resulted in greater attention (larger LPP) to fear faces among older children.•Period of development may impact attention bias development among youth.
