Check-reading as a function of pointer symmetry and uniform alignment

Abstract

Check-reading of aircraft instruments is done to assure a normal indication. Four patterns of sixteen-dial panels employing the principles of uniform alignment, pointer symmetry, and subgroup pointer pattern were tested under tachistoscopic viewing conditions with 48 naive male Ss. Each pattern was prepared in 19 stimulus panels. Pointer symmetry and uniform alignment facilitate check-reading, and are superior to subgrouping. Check-reading improves with a relatively short amount of practice, and some transfer exists between panels with different pointer positions.
