  • Electroencephalography (EEG) measures neural activation due to various cognitive processes. EEG and event-related potentials (ERPs) are widely used in studies investigating psychopathology and neural substrates of psychiatric diseases in children and adolescents. The present study aimed to review recent ERP studies in child and adolescent psychiatry. ERPs are non-invasive methods for studying synaptic functions in the brain. ERP might be a candidate biomarker in child-adolescent psychiatry, considering its ability to reflect cognitive and behavioral functions in humans. For the EEG study of psychiatric diseases in children and adolescents, several ERP components have been used, such as mismatch negativity, P300, error-related negativity (ERN), and reward positivity (RewP). Regarding executive functions and inhibition in patients with attention-deficit/hyperactivity disorder (ADHD), P300 latency, and ERN were significantly different in patients with ADHD compared to those in the healthy population. ERN showed meaningful changes in patients with anxiety disorders, such as generalized anxiety disorder, separation anxiety disorder, and obsessive-compulsive disorder. Patients with depression showed significantly attenuated RewP compared to the healthy population, which was related to the symptoms of anhedonia.

  • The purpose of this study is to examine how adolescent children's exposure experience of domestic violence influences their psycho-social maladjustment. The SPSS 10.0 for Windows was used to analyze data obtained through 589 adolescents who attend middle school in Gwangju area. Major findings are as follows: 1. Domestic violence exposure in adolescent children was considerably serious; 84.4% child abuse by parents, 66.0% witness of father-to-mother abuse. 2. Child abuse and wife abuse had close relation in occurrence and severity. 3. Internalizing problems, externalizing problems, and social competence of adolescents were different by the victim of child abuse, the witness of wife abuse, and the style of domestic violence exposure. 4. Domestic violence exposure had a positive impact on the adolescent children's psycho-social maladjustment.
