This thesis is addressed to the problem of determining
the magnitude and direction of artillery observer errors
in flashing high burst registrations with the M2 aiming
circle, The task of flashing high burst registrations was
simulated by using neon lamps to represent the visual
stimulus presented by an exploding artillery round. Nineteen
field artillery officers were used as subjects in an
experiment conducted to collect the necessary information. It was found that larger errors were committed for measurements
made in the vertical direction than for those in the
horizontal direction. Most accurate measurements were
made for flashes appearing in the first quadrant of the
aiming circle reticle and for those appearing near the
center of the reticle.
