Correlations of age, disease duration, language composite, and perspective-taking score with performance in the sighted and color-blind conditions
| Mean (SD) | Sighted | Color blind | |
|---|---|---|---|
| Age (years) | 64.65 (9.10) | ρ = 0.21, p = 0.37 | ρ = 0.21, p = 0.37 |
| Disease duration (years) | 4.50 (3.24) | ρ = 30, p = 0.19 | ρ = 0.14, p = 0.56 |
| Language composite | 92.04 (6.72) | ρ = 0.12, p = 0.63 | ρ = 0.32, p = 0.20 |
| Perspective taking (IRI) | 17.75 (18.75) | ρ = −0.24, p = 0.36 | ρ = −0.55, p = 0.02* |
