This study examined the possible effects of short-term practice during each trial of a digital compensatory control task with and without input preview. The results for 8 subjects showed that the RMS error performance varied substantially between blocks, the extent of which depended on the reference input variance, the autocorrelated nature of the input and on whether or not preview was provided. The only consistent and significant performance improvement due to practice occurred early during the practice period (between Blocks 1 and 2 of the total of five blocks).
