The reported frequency values are logarithmic function values of the lemma counts from the Dutch version of the CELEX database (Baayen et al., 1993). For the determination of the age of acquisition, subjects were asked to estimate the age at which they had first learned the stimulus word. Familiarity and imageability ratings were scored on 7 point Likert-type scales (De Deyne et al., 2008). Correlation coefficients (Corr. coeff., p value) were calculated between the similarity matrix of the 24 stimuli and the dissimilarity matrices of the stimuli based on the differences in absolute values of their lexical parameters.
