THE EFFECT OF CONVEX MIRROR DISTROTION ON ACUITY AND SIZE DISCRIMINATION TASKS

Six 3 x 5 inch convex mirrors of varying optical quality were tested under simulated twilight conditions for accuracy and reaction time on acuity and size discrimination tasks. Subjects were 12 male and female college students ages 17 - 21 and 12 employed males and females between ages 45 - 62. Sex yielded a minor difference; older subjects worked more slowly and made more errors. The first-surface mirror with good cosmetic appearance was best for the size discrimination task; the first-surface mirror with fair cosmetic quality was best for the acuity task. The results were discussed in regard to rear-view vision with a convex mirror positioned on the right-front fender of a car.
