Range Estimation Error as a Function of Rate of Stimulus Movement

The primary goal of this research was to study errors in stadimetric estimation. Earlier workers had hypothesized that differences in angular velocity of stimuli associated with direction of movement resulted in differences in error between incoming and outgoing stimuli. Therefore, an experiment was performed which investigated differences in range estimation error as a function of three rates of movement. The results for 6 observers showed that errors were consistent regardless of rate of movement.
