... Among the various general cognitive abilities (e.g., language ability and episodic memory: Naito, 2003;Ruffman, Slade & Crowe, 2002), measures of IQ are considered as major confounding factors in studying ToM (Yirmiya, Solomonica-Levi, Shulman & Pilowsky, 1996). However, the findings regarding the associations between performance on ToM tasks and measures of IQ are rather equivocal in various clinical populations (e.g., schizophrenia, autistic spectrum disorders) and healthy controls (e.g., Bora, Yucel & Pantelis, 2009;Brune, 2003;Buitelaar, van der Wees, Swaab-Barneveld & van der Gaag, 1999;Harrington, Siegert & McClure, 2005;Hur, Byun, Shin et al., 2013;Ozonoff et al., 1991;Peterson & Miller, 2012;Pickup, 2008;Sprong, Schothorst, Vos, Hox & van Engeland, 2007;Yirmiya, Sigman, Kasari & Mundy, 1992). Of interest, verbal IQ has been associated with performance on the RMET (Ahmed & Stephen Miller, 2011;Golan, Baron-Cohen, Hill & Golan, 2006;Kenyon, Samarawickrema, Dejong et al., 2012;Peterson & Miller, 2012;Stanford, Messinger, Malaspina & Corcoran, 2011). ...
