“…In addition, children employ the NOM‐marked argument typically as the actor of an event (e.g., Lee & Cho, 2009) and acquire the NOM earlier and use it more reliably than the ACC (e.g., Cho, 1982; Jin, Kim, & Song, 2015). These reports suggest the asymmetric development of knowledge about case markers, which is consistent with the findings in many case‐marking languages (e.g., Dittmar et al., 2008; Strotseva‐Feinschmidt, Schipke, Gunter, Brauer, & Friederici, 2019). This is attributable to input properties: a stronger association (measured by ∆P ) between the NOM and the agent role (and vice versa) than that between the ACC and the theme role (and vice versa) for the transitive construction (Shin, 2020).…”
