Factorial analysis of complex psychomotor performance and related skills.

Abstract

A factor analysis of 23 test variables (16 apparatus psychomotor tests and 7 printed tests designed as possible substitutes for apparatus tests) and a flying training criterion is reported. 9 factors rotated to an orthogonal simple structure are described. There are certain broad group factors of psychomotor skill which may account for performance on a wide variety of different psychomotor tasks. Although some of the factors defined in psychomotor tests may also be sampled by printed tests, there is evidence that psychomotor tests sample some factors not covered by any other kinds of tests.
