Abstract:

Mans 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.
