Note. Beta-coefficient and p-Values of the mixed linear regression models to in-degree, out-degree and centrality of pronouns in semantic graph models and their normalized frequencies with the fixed effect of sessional progression and random effect of participants. Pronouns were classified into four categories representing the speaker (I– including I, me, my, etc.), interlocutor (You– including you, yours, yourself, etc.), speech participants (We– including, we, us, ours, etc.), and others (They– including she, he, they, hers, his, their, etc.). Significant results are tagged with asterisk. Results that survive Bonferroni correction for multiple comparisons are tagged with ^Bonf. (corrected α = 0.004 for graph features and 0.0125 for normalized frequency comparisons).
