This study examined patterns of frontal lobe asymmetry in relation to individual differences in emotion regulation in 5–7 year old children. Temperament (as measured with parent report on the Child Behavior Questionnaire (CBQ; Rothbart, 1995) and attachment security (as measured with the Separation Anxiety Test (SAT; Kaplan, 1985) were examined in a sample of 67 children. Alpha (6–12 Hz) power (μv<super>2</super>/Hz) was examined using electroencephalogram (EEG) at mid-frontal sites (F3 and 174) during three stimulus conditions: Post-maternal separation, happy/sad, and separation/reunion. It was expected that while temperamental differences would be related to frontal asymmetry during all stimulus conditions, attachment security differences would only be related to patterns of frontal asymmetry when the attachment system was activated (e.g. post-maternal separation, separation/reunion). Results indicated (1) a significant main effect of temperamental negative affect in most stimulus conditions, showing that low negative affect was associated with increased right-frontal activity; (2) a main effect of attachment security in the reunion stimulus condition, showing that subjects with insecure attachment were more likely to show increased left-frontal activity; (3) a temperament by attachment interaction in all three conditions, showing that insecure groups rated as high in negative affect showed the greatest degree of asymmetry (lateralized to the left) due to a decrease in right-frontal activity during stimulus presentation; (4) a significant main effect of age all three stimulus conditions, showing a dramatic shift in frontal activation patterns between 5 and 7.5 years of age. Younger children showed stronger left-frontal asymmetry at baseline, but in response to the stimulus conditions showed a decrease in left frontal activation while the older children showed an increase in left frontal activation. These findings are among the first to find a systematic relation between attachment security and frontal lobe activation patterns. The results highlight the importance of emotional context when interpreting frontal lobe activation patterns as indicative of differences in emotion regulation, and indicate that further research is needed on normative developmental changes in both frontal lobe asymmetry and emotion regulation.
