TRANSFER OF TRAINING AS A FUNCTION OF TASK DIFFICULTY IN A COMPLEX CONTROL SITUATION
GENERAL DYNAMICS CORP GROTON CONN ELECTRIC BOAT DIV
Two submarines, differing with respect to their dynamic response characteristics as a function of differences in hull size, were simulated at each of two speeds slow and fast. Four groups of 20 subjects were trained on a depth-keeping task, one group on each of 4 hull-speed combinations. Following training, 3 subgroups of 5 subjects from each group were tested on the other 3 hull-speed conditions, with the remaining 5 subjects tested on the same system. This was done to determine the degree to which training on any 1 of the 4 systems transfers to the other 3 systems. It was found that, on the basis of mean time on target scores per five-trial block, the more difficult systems to control were those with the longer control lags. These were the small hull at slow speed and large hull at slow systems. It was also found that training on the most difficult control system, the large hull at slow speed system, produced generally better transfer effects than did training on any other system. Author
