Abstract : The findings of research carried out under contract N00014-79-C-0550 between the Office of Naval Research, Engineering Psychology Programs and The Catholic University Human Performance Laboratory are summarized. This research investigated the role of knowledge-based or top-down processing in the perception of non-linguistic, transient signals. The experiments addressed issues in transient-pattern classification, target observation, attentional focusing, auditory induction, and computer-based performance aids. The theoretical significance and naval relevance of the research is considered.
