Abstract:

The status of an investigation into a novel method for the collection of visual performance data is described. This technique, called the fluctuation limen method, has obvious advantages in certain psychophysical investigations owing to the rapidity with which thresholds can be estimated. Instrumentation for efficient data collection has been devised, and some preliminary studies were made to evaluate the method in terms of absolute values obtained by its use, as well as to determine the effects of training. Other studies are needed to assess the method in terms of the critria which have been enumerated. While the data are fragmentary, all indications are that the technique deserves further study as a possible means for the rapid collection of visual performance data. Author
