.97, and RMSEA = .05. The results are in keeping with a cross-sectional SEM analysis of the relationships among executive function, complement comprehension, and FB reasoning with a much smaller sample (N=90) by Farrant et al (2012). However, they tested EF by a card-sorting task and used a second order FB task, and they only had one measure of language, the memory for complements task. We conclude that specific aspects of language acquisition have separate direct effects on explicit FB reasoning, both concurrently and longitudinally. Likewise, inhibitory control contributes directly to performance on FB tasks. Language also contributes indirectly through effects on IC. The longitudinal SEM supports both general theories of the effects of language on FB reasoning (Astington & Baird, 2005), and the specific effects of complement syntax (de Villiers & de Villiers, 2009). It also supports a separate role for IC, as proposed by Moses (2001) and Carlson and Moses (2002).
