Effect of Vibration upon Speed of Perception while Reading Six Point Print
Miles Albert Tinker · The Journal of Educational Research · 1953
READING IN any situation where there is vibration of the reading material, as on a train, is apt to become an annoying experience. It would seem that the blurring caused by the vibration introduces a se vere visual task that may induce visual fatigue. In an initial experi ment, Tinker (4) found that vibration retarded speed of perception by 5.19 percent when reading 10.point book type. This was a significant reduction in efficiency. The typography involved was an optimal printing arrangement. The question arises whether the deleterious effects of vibration are increased when the typography is non-optimal. The specific problem in this experiment is to investigate the effect of vibration upon speed of perception while reading material printed in six point Roman (ordinary type) and six point italic type.
