The random slope of perceptual speed is the estimated person-specific rate of change in the perceptual speed domain variable over time. It comes from a linear mixed effects model with perceptual speed as the longitudinal outcome. The model controls for age at baseline, sex, and years of education.
Note: Time in this model refers to years since baseline interview.
