Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Differences in dimensional indicators (valence and arousal) measured by facial expression analysis software (FaceReader) between VMC and FTF conditions (VMC effect). For each indicator, the overall intensity mean throughout the interview and the event-based intensity mean (defined as FaceReader score 0.26 or above) are estimated using Bayesian analysis, with 95% credible intervals calculated at both individual and group levels. | — |
Secondary
| Measure | Time frame |
|---|---|
| (1) VMC effect on categorical indicators (six basic emotion scores: happiness, sadness, fear, anger, disgust, and surprise) measured by FaceReader, estimated using Bayesian analysis with 95% credible intervals. (2) Frequency and duration of emotional expression events per condition, reported as descriptive statistics (median, interquartile range). (3) Participants' subjective experiences related to differences in emotional expression between VMC and FTF conditions, explored through semi-structured interviews and analyzed using thematic analysis. | — |
