“…Tattling can be essentially defined as the reporting of another person's violation of a normative expectation to a third party, a behavior emerging as early as 18 months of age (Dunn & Munn, 1985). It has been widely documented in several settings, varying from family (Ross, Smith, Spielmacher, & Recchia, 2004) to preschool and other educational (Chiu Loke, Heyman, Forgie, McCarthy, & Lee, 2011;Ingram & Bering, 2010;Lancelotta & Vaughn, 1989) environments as well as to controlled experimental settings tattling between siblings reduces significantly from ages 4 to 6. It is proposed that by the time children reach adolescence such a behavior could render negative consequences from peers as well as adults and would therefore be used less frequently and in a covert manner (Friman et al, 2004;Ingram & Bering, 2010).…”
