Abstract:

The mission of this contract was to determine how performance in information processing tasks may be optimized. The research spanned five major topics 1. Performance in visual search and detection tasks. These studies have demonstrated substantial capacity for parallel processing of display elements. 2. Perceptualizing data displays. The use of some unconventional formats for the representation of complex sets of data has been explored. 3. Selective attention. This research on attention is consistent with the notion that attention does not operate at the earliest stages sensory or perceptual of information processing, but is restricted to later stages such as memory scanning or response selection. 4. Factors affecting stimulus comparison. The major findings have to do with strategies for comparing stimuli. 5. Short-term memory. Two experiments examined factors that affect the retrieval of well-learned items digits from short-term memory.
