Angular estimation

Abstract

In one study, 10 Ss estimated the directional trend (heading) of simulated radar trials, using different response modes; rotary switch adjustment permitted better accuracy than numerical estimation. Varying the displayed length of the simulated trials from –5₁₆ to 1½ inches had no apparent effect on estimation accuracy. 5 civilian Ss proved more accurate than 5 airmen. In a 2nd study, 20 Ss estimated the angular position of lines varying in length from ⅛ to 1 inch, using equipment which permitted switch adjustment and numerical estimation only to the nearest 10 degrees. Results were the same as before. In addition, this report notes differences in estimation accuracy and bias related to the actual angle of displayed lines over a 360-degree range, as well as biasing effects of right- vs. left-handed switch adjustment.
