A description of the perceptual/psychomotor ability requirements for performing the tasks of various Air Force career fields was sought. An analysis of the literature relating to taxonomies, measurement considerations and job analyses yielded a taxonomy containing thirteen perceptual/psychomotor classes along with techniques for collecting the required data. The methods were first tested in two career fields, revised, and then were applied in a large scale data acquisition effort which included thirty-five Air Force career fields. This work included over eight hundred job incumbents at ten Air Force bases. High and low perceptual/psychomotor ability requirements were determined for each of the thirty-five Air Force career fields. Indexes of profile similarity indicated that the perceptual/psychomotor requirements for most career fields are, in part, unique. A factor analysis of the data indicated that the perceptual/psychomotor ability taxonomy can be described by three factors: visual, auditory, and manual factors. The conclusions of the study point to (1) the adequacy of the taxonomy for describing the perceptual psychomotor requirements of Air Force career fields, (2) the utility of the technique employed for future investlgations of this sort, (3) the partially unique perceptual/psychomotor requirements for various Air Force career fields, and (4) the adequacy of the present effort as a basis for perceptual/psychomotor test development for use as an aid in career selection and classification.
