1. The effect of three doses of either aspirin (1280 mg each) or dimenhydrinate (Dramamine) (100 mg each) in an 8 h period on visual processes was investigated double‐blind on sixteen volunteer subjects. 2. Tests included night‐vision, colour‐discrimination, stereoacuity and stereopsis, reaction‐time, pupil size, eye‐movements, visual evoked cortical potentials, electroencephalographs, a dial‐reading task, and a test of texture discrimination. 3. Both drugs affected colour discrimination, and dimenhydrinate degraded night‐vision, reaction‐ time, and stereopsis. 4. The effect of aspirin was minor, but the impairments produced by dimenhydrinate appear to be of practical importance.

“…The various textures were generated by manipulating the probability that adjacent dots in the matrix would be illuminated or not. Previous work with these textures (Santoro & Fender, 1976) had identified percepts of granularity (varying from fine to coarse) and of directionality (horizontal, vertical or diagonal). On the basis of this work, specific textures were selected to be discriminated.…”

A battery of visual, perceptual, and cognitive tests, believed to be important for operation of visual sonar displays, was administered to 100 sonar technicians. The measures varied from standard paper-and-pencil tests to computer-administered perceptual tasks. The results of 33 different measures on these men were compiled and subjected to a factor analysis. The factors extracted represent cohesive and reasonable groups which cut, to some extent, across testing techniques. However, all of the paper-and-pencil, perceptual-cognitive tests had high loadings on the same common factor, a result with general implications for occupational testing.

To determine which of several visual stimuli yields the greatest interhemispheric asymmetry in the visual evoked potential. Responses to these stimuli will be used as possible measures of performance capability in sonar operators. FINDINGS Pour of the five stimuli used yielded approximately equal interhemispheric asymmetries at both the occipital and parietal locations. Subjects were generally consistent in the direction of asymmetry and showed greater amplitude in the right side of the brain. APPLICATION These results will be used in a future test of the relationship of the direction and magnitude of interhemispheric asymmetry to measures of performance in sonar operators.
