The error-related negativity (ERN; Cavanagh & Shackman, 2015; Moser, Moran, Schroder, Donnellan, & Yeung, 2013; Weinberg, Dieterich, & Riesel, 2016) is a negative deflection in the event-related potential (ERP) that occurs approximately 50ms after an error response. ERN has been used as a biomarker for anxiety; individual differences in anxiety are related to increased ERN amplitude (Moser et al, 2013; Olvet and Hajcak, 2008; Simons, 2010; Vaidyanathan et al., 2012; Weinberg et al., 2012b). ERN has also been found to be heritable in a study measuring ERN and CRN in monozygotic and dizygotic adolescent twin pairs (Anokhin, Golosheykin & Heath, 2008). The current study aims to further understand the relationship Between ERN in adolescents and their mothers. A Flanker task (Eriksen and Eriksen, 1974), was administered to 23 adolescents between the ages of 11-14 and their mothers. Results showed a significant correlation of diff-ERN (the difference in ERP-value between error and correct trials) at in adolescents and their mothers (r = 0.489, p < .05). The relationship of anxiety between mothers and their children may indicate a need for prevention of anxiety development in adolescents if their mothers are anxious.
