A project investigated the feasibility of training spatial visualization to facilitate transfer among tasks requiring these abilities and thus reduce training time and increase personnel flexibility. Eighty undergraduate college students participated in a study of from one to five days duration. Experimental subjects received extensive practice with feedback provided on a set of tasks known to require spatial visualization. Control subjects received no practice. All subjects were tested on two transfer tasks which were dissimilar to the training tasks but which required proficiency in spatial visualization for successful task performance. Results indicated that training did not significantly enhanced spatial visualization as measured by a standard ability test administered before and after training. There was no evidence that performance on the transfer tasks was affected significantly as a result of training, i.e., there was no transfer of training. Furthermore, there was no differential retention between trained and untrained groups. (Examples of training tasks are appended.) (Author/YLB)
