“…While work with young children often uses just error rates (e.g., Montgomery & Koeltzow, 2010; Sabbagh, Xu, Carlson, Moses, & Lee, 2006) , research with older children and adults frequently relies on response times (e.g., Prencipe et al, 2011). Moreover, prior work has demonstrated that error rates and cumulative response time are strongly correlated (Kramer, Lagattuta, & Sayfan, 2015; Lagattuta et al, 2011), and both have been associated with advanced ToM (Kennedy et al, 2015; Lagattuta et al, 2010, 2014). …”
