VISUAL AFTER-IMAGES AS A SOURCE OF INFORMATION.
Abstract
The report is one of 3 evaluations of differently proposed methods for increasing the ability of individuals to report the contents of briefly exposed visual displays. In this case concern was with the ability of observers to extract data from induced retinal after-images as a means of increasing the display exposure time in single glimpse situations. It was found that observers can use after-image data, and that the gain in reporting to be expected will be greatest for those situations where, without after-images, reporting is most difficult, that is, under conditions of high display load or very short exposure time. The benefit demonstrated was associated primarily with the positive after-image; however, the negative after-image was not ruled out as a persistent data source. (Author)
