Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Paired-samples tests revealed reliable pre–post differences across facial, vocal, and lexical emotion signals (e.g., facial anger and surprise; vocal anger and happiness; all p < .05), not confined to any single emotion. → Hung-Yue Suen and Kuo-En Hung 2026

q2 · i? · design · r2
Descriptive paired-samples analyses of facial, vocal, and lexical emotion patterns in the 30-day field study (N = 204); the article reports significance without effect sizes and characterizes the changes as suggesting potential regulation of emotional expression.
"Paired-samples tests revealed reliable pre–post differences across facial, vocal, and lexical signals, encompassing both negative and high-arousal expressions reflected in facial cues, vocal delivery, and word usage (e.g., facial anger and surprise; vocal anger and happiness; affectively charged lexical patterns; all p < .05)."

- Adult learners using the closed-loop ITS improved significantly across all seven BARS presentation dimensions over a 30-day practice window (Cohen's d = 0.39–0.90) — related
- Text-based emotional expression in student responses showed no statistically significant differences between Emotion ON and OFF conditions — related
- In a within-subject user study, participants showed longer positive facial expressions under the emotion-aware (Emotion ON) tutoring condition — related
- Detection-oriented emotion AI faces contextual under-interpretation: emotional signals lack stable meanings independent of person, task, culture, and situation — related
