This study investigated whether or not two different types of response oral versus written on a battery of visual perceptual tasks result in significant differences in performance in submarine school students. Secondly, the study compared their written performance to the performance in a past research investigation with submarine sonar operators using the same battery. The visual perceptual and cognitive tasks included a broad selection of visual perceptual abilities, such a speed of closures, flexibility of closure, spatial orientation perceptual speed, and induction. Several non-perceptual measures were compared with sonar operators study, including the General Classification Test GCT, Arithmetic Test, and age. The submarine school students demonstrated similar performance in the two response modalities on all but one of the visual perceptual and cognitive tests. Only the flexibility of closure task, as measured by ETSs Hidden Pattern Test, showed a significant difference in performance the written response produced a significantly higher level of performance than the oral responses for the students. Also, their performance on several of the visual perceptual and cognitive tasks, as well as on a non- perceptual variable, was significantly different from that of the sonar operators.
