An account is given of the rationale, methodology, and preliminary results of an initial research effort to develop a scheme for use as a guide in generating and applying behavioral information. Objectives are to clarify relationships between military tasks and existing psychological knowledge, indicate training problems requiring further psychological research, help formulate such research, define training needs and suitable training activities, and suggest properties of a task situation (augmented feedback, for example) which, when added to or substituted for other task properties, might improve performance. Steps for attaining these objectives are summarized, followed by combinations of manipulable characteristics (subcategory "Expectations, Sets, and Habits") with the categories of Instruction, Task Environment, and Monitored Behavior. The document also includes 12 references, a full taxonomy outline, and typical research situations as well as an example of the taxonomy in use. (LY)
