The first T-test column shows the p-values of the test between action words and abstract words; the second T-test column shows the p-values for the test between all words combined and pseudo-words. Log frequency values were obtained from the WebCelex database (http://celex.mpi.nl); SemD values obtained from Paul Hoffman and Tim Rogers (personal communication; see Hoffman, Rogers, & Lambon Ralph, 2011). All other measures retrieved from the English Lexicon Project database (http://elexicon.wustl.edu), Balota et al. (2007).
