Fixed effect estimates (β) for PPD, together with corresponding CIs
| PPD | ||
|---|---|---|
| β | CI (95%) | |
| (Intercept) | +0.220 | +0.181 to +0.259 |
| Intelligibility (A) | –0.038 | –0.068 to –0.007 |

| Copresence | +0.028 | +0.008 to +0.049 |

| Intelligibility (A) × Copresence | +0.003 | –0.040 to +0.046 |
| Intelligibility (B) × Copresence | +0.018 | –0.024 to +0.060 |
| Intelligibility (A) × Task | +0.044 | +0.001 to +0.087 |
| Intelligibility (B) × Task | +0.043 | +0.001 to +0.085 |
| Copresence × Task | –0.023 | –0.047 to +0.002 |
| Intelligibility (A) × Copresence × Task | –0.002 | –0.063 to +0.059 |
| Intelligibility (B) × Copresence × Task | –0.034 | –0.094 to +0.026 |
The backward difference contrast coding resulted in two beta estimates for intelligibility, labeled contrast A (50% compared with 20%) and contrast B (80% compared with 50%). Copresence represents the difference in BPS when doing the task in the presence of another participant, compared with alone. The task estimate represents the change in PPD when actively listening, compared with passive listening.
CIs, confidence intervals; PPD, peak pupil dilation.
