22 male, college-age Ss performed a force-reproduction task in which extent of movement was not a factor. For each trial S pushed the handle of the apparatus until the standard force was reached, held the standard 3 sec., released the handle, and then immediately regrasped the handle and attempted to reproduce the standard force. Each S had 4 trials at each of 4 standards, 1 kg., 2 kg., 3 kg., and 4 kg. The constant error was recorded for each trial. Analysis of variance indicated no significant effects of block or trial, and no interaction. It was concluded that with the range of standards used, the size of the standard did not affect the size of the constant error.
