“…Based on previous studies ( Diamond, 2002 ; Sowell et al, 2004 ; Crone et al, 2006a , b ; Durston et al, 2006 ; Luciana and Collins, 2012 ; Ferdinand and Kray, 2014 ; Gennatas et al, 2017 ), which suggested that the biological structure and the psychological function of the frontal lobes differed markedly between the children and adults, we predicted that compared to adults, children might show a different pattern of ERP response to the informative value of feedback. Particularly, children might be less sensitive to the informative value of negative feedback, since they were more likely to be driven by positive feedback ( Somsen, 2007 ; van der Veen et al, 2008 ; Zhuang et al, 2017 ). In addition, based on the results of the two studies in our laboratory ( Li et al, 2011 ; Huang et al, 2013 ), we predicted that the processes of informative value of feedback for children might be observed at the left sites.…”
