Prediction of vocational proficiency in three machine operations

Abstract

Learning curves of 190 women operators in trimming, covering, and hemming operations in knitting mills showed an early sharp rise, negative acceleration, plateaus, and a point beyond which little improvement occurred. Those who left the company were found to be less proficient in trimming and hemming than those who remained at work. The reliabilities of production records were not high; reasons for this are advanced. Early proficiency is not a very good measure for prediction of later proficiency. Speed of learning in each operation is closely related to average hourly output. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
