Abstract
The overall objective of this study was to identify and consider experimental techniques for locating and valuating data patterns and informational chunks that are meaningful to the tactical decision-maker in tasks such as the analysis of battlefield map positions. This objective is motivated by the long range need to (1) identify for a given class of problem situations the informational characteristics that constitute the basis for generating effective evaluation functions, and (2) relate the designation of meaningful units of information to the design of user-compatible data modules and data-searching and combining algorithms for tactical decision systems. More specifically, the objectives were as follows: 1. To compare the performance of battlefield experts with that of novices on the accuracy of recalling both coherent and noncoherent battlefield map positions; 2. To identify and apply experimental techniques for locating and distinguishing between the informational chunks that are formulated by the battlefield decision maker; 3. To identify the likely basic units that constitute the semantic contents of formulated chunks for specific battlefield maps; 4. To determine the comparative sizes of the average chunks for novices and experts; 5. To determine the comparative chunking frequency of novices and experts for a given battlefield scenario; 6. To determine the effect on recall, chunk size, chunk unit, and chunking frequency of varying the length of time given for viewing, processing, and assimilating the information.
