Psychological Aspects of Camouflage Design and Detection: Stress and Visual Information Processing

摘要

The visual detection of a concealed target involves the interaction of object characteristics and observer-related variables. This report briefly summarises object characteristics which may affect detectability, and then concentrates upon observer variables. Some of the physical limitations of the human optical system are mentioned. An information processing theory is reviewed and adopted as a model upon which some hypotheses are based. In the case of a search of a large, complex field, automatic processing of information may lead to the selection of likely target areas, however controlled search processes may be required to scan the information in an automatically selected array.
