This report is the third six months progress report on a research program titled Parameters of Human Pattern Perception, supported under Project THEMIS. The completion of the initial methodological phase of the program is reported developments in this phase include the achievement of a capability for obtaining quantitative measures on patterns and the completion of research supporting the use and selection of a graded response for pattern identification. Empirical efforts are reported, these being directed primarily at providing a basic understanding of what features people use in pattern recognition tasks and how they use these features. The principal conclusion from these studies is that humans detect and make use of the statistical distributions of features within a set of patterns as a basis for selecting a useful set of features. Theoretical developments relating to computer simulation of human performance in a pattern recognition task are also described. Author
