Fig. 1 –

Significant group differences for discriminant features. All group differences are significant at p < .05 after Benjamini-Hochberg correction for False discovery rate of .05. Most Y-axis labels were omitted to lighten the plot. Imageability, Dominance, Frequency, Concreteness are based on Likert scales from the psycholinguistic databases listed in Section 2.5.1. Proportion of Uncertainties is the ratio of number of uncertainties in the transcript divided by the total number of words. Nouns/number of roots is the ratio of number of nouns divided by the number of sentence roots in the transcript. Number of left children/number of roots is the ratio of number of left children divided by number of sentence roots in the transcripts. Brunet’s W index results from the equation in Table A1 and yields an inverted scale: a higher Brunet’s W index corresponds to lower lexical diversity. Mention of the drink is plotted as the percentage of transcripts in which the drink was mentioned.
