“…Perhaps, the word task was different enough from sonar and equally novel for both groups of subjects, such that no differences were found. Similar results (no group differences) have been found in other sonar simulation studies using comparison groups (Kobus, Lewandowski, & Flood, 1987;Lewandowski, Kobus, Flood, & Hoyer, 1988).…”

A group of 20 experienced sonar operators (SO) was compared with a group of 20 non-operators (NO) on a computerized word decision task. The subjects had to respond quickly and accurately in determining whether a word/words presented visually and/or aurally (at the same time) was/were related to a given category (i.e., animals). Response speed, decision accuracy, and recall of words related and unrelated to the categories were recorded. Results indicated no group differences in any of the dependent measures, thus experience in a bimodal input situation did not provide sonar operators with a performance advantage on the experimental task. All 40 subjects performed faster and more accurately when the information was presented visually, and the words were related to a given category. Subjects performed about as quickly and accurately when the same word (related to the category) was presented concurrently in both modalities, however, recall of these words was significantly higher than all other conditions. Overall, the data are consistent with other studies which demonstrate no loss and some gain in the bimodal redundant (same word) condition. This study is one of the first to demonstrate an enhancement in higher level cognitive performance (such as memory recall) in a bimodal task.

“…IQ tests were not administered, but previous research with this population revealed average to above average mental abilities (Lewandowski, Kobus, & Flood, 1987). The range of this group's educational level was from 14 to 20 years (M = 14.2 yrs.…”

“…Further, Kobus, Lewandowski, and Flood (1987) administered a battery of cognitive and personality tests to experienced operators and trainees. They found that experienced operators had better perceptual-organizational abilities, greater attention to visual details and less anxiety (state) than inexperienced subjects.…”
