AbstractParents of atypically developing children such as parents of children with ASD, attention deficit hyperactivity disorder, and intellectual disability experience higher levels of parenting stress than parents of typically developing children. However, whether they possess enhanced emotional negativity bias was unclear. In the present study, 28 parents of typically developing children and 29 parents of atypically developing children were recruited. The emotional Stroop task and event‐related potentials were adopted to measure their emotional negativity bias, in which participants were required to respond to the borders' color of face pictures. Behaviorally, the impact of parenting stress on emotional negativity bias was not found. At the electrophysiological level, the P2 differential amplitude (negative minus positive) was greater in parents of atypically developing children than in parents of typically developing children, reflecting an enhanced early attentional bias toward negative faces. N2 amplitude for the emotionally negative face was smaller than the positive face in parents of atypically developing children, indicating a too weak attentional control to inhibit distractors. Furthermore, sustained attention to negative faces was observed in parents of atypically developing children, that is, the emotionally negative face elicited greater frontal P3 (300 ~ 500 ms) than the positive faces. These findings revealed that compared to parents of typically developing children, parents of atypically developing children owned an enhanced emotional negativity bias at the early and late stages of information processing.
