Abstract:

The relative discriminability of 210 stimulus items was determined by a comparison of response time and errors in a search task in which the operator identified symbols as examples or non-examples of a prespecified target item. The characteristics of the target item relative to non-target items determined the response times to target and non-target items and the variability among non- target response times. Non-targets which were highly confusable with the target tended to increase response time and variance. Symbols were ranked according to target and non-target response times.
