“…The predominance of nouns is also reflected in available norm studies (Bird, Franklin, & Howard, 2001). Whenever adjectives are included in norm studies, they are either few in number (Altarriba, Bauer, & Benvenuto, 1999;Berrian, Metzler, Kroll, & Clark-Meyers, 1979;Grühn & Smith, 2008;Võ et al, 2009) or data for a small number of variables is obtained (Anderson, 1968;Bird et al, 2001;Brysbaert, Stevens, De Deyne, Voorspoels, & Storms, 2014a;Kuperman, Stadthagen-Gonzalez, & Brysbaert, 2012;Lynott & Connell, 2009;van Loon-Vervoorn, 1985). To avoid sampling bias, to allow for generalization, and to ensure that the critical lexical variables can be controlled for, norming data for a variety of words and variables are required, however (Clark & Paivio, 2004;Kousta, Vinson, & Vigliocco, 2009).…”
