“…Lexical variables refer to "word properties, such as word frequency and concreteness, which reflect differences in the way in which words are represented in long-term or lexical memory" (Stuart & Hulme, 2009, p. 157). Lexical effects include the better recall of high-frequency words over lowfrequency words (the word frequency effect; see, e.g., Hulme, Stuart, Brown, & Morin, 2003;Roodenrys & Quinlan, 2000), of words over nonwords (the lexicality effect; see, e.g., Hulme, Maughan, & Brown, 1991;Multhaup, Balota, & Cowan, 1996), of concrete words over abstract words (the effect of word concreteness or imageability; see, e.g., Miller & Roodenrys, 2009;Walker & Hulme, 1999), and of semantically related words over unrelated words (the effect of semantic similarity; see, e.g., Poirier & Saint-Aubin, 1995;Tse, 2009). Saint-Aubin and Poirier (1999) showed that lexical variables modulate item retention.…”
