Resting frontal EEG asymmetry in children: meta-analyses of the effects of psychosocial risk factors and associations with internalizing and externalizing behavior.

摘要: Asymmetry of frontal cortical electroencephalogram (EEG) activity in children is influenced by the social environment and considered a marker vulnerability to emotional behavioral problems. To determine reliability these associations, we used meta-analysis test whether variation resting EEG asymmetry consistently associated with (a) having experienced psychosocial risk (e.g., parental depression or maltreatment) (b) internalizing externalizing behavior outcomes ranging from newborns adolescents. Three meta-analyses including 38 studies (N = 2,523) 50 pertinent effect sizes were carried out. The included analyses reported associations between (k = 20; predominantly maternal as factor) well (k = 20) (k = 10) outcomes. Psychosocial was significantly greater relative right asymmetry, an size d = .36 (p < .01), effects being stronger girls. A non-significant relation observed symptoms (d = .19, p = .08), whereas no association left (d = .04, p = .79). Greater appears be fairly consistent presence familial stressors but power directly predict problems modest.
