Abstract

Man's ability to estimate weights was determined for two lifting conditions: direct manual lifting and remote lifting by means of an Argonne National Laboratory Model 8 Master-Slave Manipulator. The effect of interpolated weight-lifting experience upon absolute judgments of weight was also examined. Results show that: (a) means of estimates made by subjects who lift weights remotely are greater than means of estimates made by subjects who lift the same weights directly; (b) subjects tend to underestimate weights lifted directly; (c) estimates for the remote-lifting condition, even though more accurate on the average, are more variable; and (d) the tendency for subjects to underestimate weights which follow heavier weights and overestimate those which follow lighter weights is more pronounced for direct lifting than for remote lifting.
