Length is the total number of letters summed across both items in each pair; Frequency is the average log lemma frequency across each pair, based on the American National Corpus (Reppen et al., 2005); Age of acquisition is the average across each pair in years from Kuperman et al. (2012); Concreteness is the average across each pair obtained from the MRC database (Coltheart, 1981).
