into a spectrum of disinhibitory disorders (Cohen et al., 1997; Hada et al., 2000; Kamarajan et al., 2006; Kamarajan et al., 2005a; Pfefferbaum et al., 1991; Porjesz et al., 2005). It should be emphasized that most of the higher cognitive functions, including semantic memory or semantic working memory are dependent on basic cognitive functions, at least partially and thus we can also attribute the semantic priming deficits observed in this study to deficits in cognitive inhibition.
