The document is concerned with the premise that complex equipment cannot be used and maintained effectively without the ability to understand technical manuals. In addition to textual material, such manuals contain information in graphic form, such as line drawings, photographs, and engineering diagrams. In the context of transferring American military equipment to the Armed Forces of the Republic of Vietnam, certain abilities related to interpreting technical graphic material were investigated. A sample of 82 Vietnamese Air Force technicians served as subjects in several experiments. The men performed less effectively than American controls in several measures of spatial aptitude which involved the ability to comprehend graphic conventions. Recommendations are made which include the development of special training methods to overcome deficiencies in interpreting technical illustrations.
