Early adverse experiences are believed to have a profound effect on inhibitory control and the underlying neural regions. In the current study, behavioral and event-related potential (ERP) data were collected during a go/no-go task from adolescents who were involved with the child welfare system due to child maltreatment ( = 129) and low-income, nonmaltreated adolescents ( = 102). The nonmaltreated adolescents were more accurate than the maltreated adolescents on the go/no-go task, particularly on the no-go trials. Paralleling the results with typically developing populations, the nonmaltreated adolescents displayed a more pronounced amplitude of the N2 during the no-go trials than during the go trials. However, the maltreated adolescents demonstrated a more pronounced amplitude of the N2 during the go trials than during the no-go trials. Furthermore, while the groups did not differ during the go trials, the nonmaltreated adolescents displayed a more negative amplitude of the N2 than the maltreated adolescents during no-go trials. In contrast, there was not a significant group difference in amplitude of the P3. Taken together, these results provide evidence that the early adverse experiences encountered by maltreated populations impact inhibitory control and the underlying neural activity in early adolescence.
早期不良经历被认为对抑制控制和相关的神经区域有深远的影响。在当前的研究中，对由于虐待儿童而被儿童福利系统介入的青少年（n = 129）和低收入、未受虐待的青少年（n = 102），在进行 Go/No-Go 任务时收集了行为和事件相关电位（ERP）数据。与受虐待的青少年相比，未受虐待的青少年在 Go/No-Go 任务中的表现更准确，尤其是在 No-Go 试次中。与典型发展人群的结果相似，未受虐待的青少年在 No-Go 试次中 N2 的振幅比在 Go 试次中更大。然而，受虐待的青少年在 Go 试次中 N2 的振幅比在 No-Go 试次中更大。此外，虽然两组在 Go 试次中没有差异，但在 No-Go 试次中，未受虐待的青少年的 N2 振幅比受虐待的青少年更负。相比之下，P3 的振幅在组间没有显著差异。综上所述，这些结果表明，受虐待人群所经历的早期不良经历会影响青少年早期的抑制控制和相关的神经活动。
