Recent research in predicting aviator performance in flight training from measures of divided attention performance has emphasized the need for the development and refinement of testing methods, investigation of the range and consistency of the individual differences associated with the measures, and the relationship of these measures with scores on existing paper-and-pencil tests currently used for selection of aviators. The goals of this study were to investigate (1) test-retest reliability coefficients of single and dual-task performance-measures over separate test days, (2) the range and consistency of individual differences in the measures and degree of relationship of the attention scores to scores on a standard set of aviation selection tests, including the Academic Qualification Test (AQT), Mechanical Comprehension Test (MCT), Spatial Apperception Test (SAT), and Biographical Inventory (BI). The investigation of these relationships is an important initial step in planning subsequent investigations of the validity of these attention measures as predictors of performance in various phases of naval aviation training. Test-retest reliability is important in ensuring that changes in subject motivational levels, physiological states, or rate of skill acquisition do not bias the measurement of the skills being assessed from day to day. Relationships between single- and dual-task performance are important in determining the independence of time-sharing of the candidate from separate task performance capability. The correlation of attention measures with the paper-and-pencil tests will determine the feasibility of continuing the investigation of these measures as independent predictors of aviator performance.
