A contribution to manual aptitude measurement in industry

Abstract

A study was made of the relationship of the O'Connor finger and tweezer dexterity tests and the success of workers in a watch factory. Performance on the tests was expressed in terms of time score, rate of improvement, and ratings on quality of performance. Only the first and third measures yielded useful predictions of job success.
