Abstract
The effect of subliminal and supraliminal accessory stimulation (white noise) on a visual detection task was determined through the use of the Theory of Signal Detection (SDT). Both the most extreme level of subliminal stimulation (–15 db) and the most extreme level of supraliminal stimulation (+15 db) resulted in the greatest increase in sensitivity ( d′) but neither had any effect on S's criteria (Beta).Keywords
