Therefore, these differences were followed up with ANOVA tests (Table 1). For the Principal Persona, significant effects of Persona description variants were found for all the Persona perception dimensions. For the Student Persona, all but the Clarity dimension showed significant effects of the Persona description variants, and for the Teacher Persona, only the dimensions of Completeness, Credibility, and Likability showed significant effects. Significant ANOVA tests were, similar to the procedure in the clinical context, followed up with pairwise comparisons, reported in the Supplementary Materials (Tables S8-S10). For the Principal Persona, all the pairwise comparisons showed significant differences between the Persona description variants in all the Persona perception dimensions. The Clarity, Credibility, Empathy, and Likability dimensions were most favorably perceived for the Bard variant of the Persona description, while for the Completeness dimension, \begin{table}
