“…For example, women (Davis, 1999;Dudycha & Dudycha, 1933;Mullen, 1994) reported earlier first memories than men in some studies, but in other studies (Peterson & Nguyen, 2010;Peterson, Smorti, & Tani, 2008;Peterson, Wang, & Hou, 2009;Wang & Conway, 2004;West & Bauer, 1999) no gender difference was found.
