Abstract
Latent construct structural equation modeling of tile relations among age, self-rated health, and speed was conducted with two samples, each containing 372 adults between 18 and 87 gears of age. The major resul ts were confirmed is both samples. Self-rated health, sensory-motor sp eed, perceptual speed, and reaction time speed all decreased as age in creased, but health only partially mediated the relationship between a ge and speed. There were direct effects of age on all types of speed i n addition to the indirect effects of age on speed through the self-ra ted health measures, and there were direct effects of age on perceptua l speed in addition to the indirect effects through sensory-motor spee d.
