The degree of ' phenomenal regression ' to real velocity differs in different 

 individuals and these differences prove to be persistent and characteristic 

 of the individual concerned. It is not known whether these differences 

 are of any practical importance. They do not appear to be correlated with 

 other visual phenomenal regression effects. 



Afternoon. 

 Mr. H. G. Maule. — Movement study in industry (2.0). 



In the course of an investigation of time and motion study in the laundry 

 industry several facts have been disclosed, most of which are simply in 

 agreement with the work of previous investigators. 



Output graphs under different circumstances of work have been com- 

 pared. Instances of long periods of uninterrupted work show the usual 

 fluctuation in hourly output. A considerable falling off of output is noted 

 towards the end of a long day's work. Where morning rest-pauses are 

 given the morning output is found to be more consistent. In one instance 

 where rest-pauses were given in the morning and in the afternoon the greatest 

 consistency of output was recorded. Though this is in agreement with the 

 work of other investigators, it is contrary to the common opinion of most 

 of the workers themselves. 



A combination of time study and motion study demonstrated that, 

 in the instance where production was highest and hourly variation least, 

 the actual movements of the workers in the performance of their task was 

 the best. These workers had been given definite training at an early stage. 

 It is far more common to find that workers ' pick up ' the methods as best 

 they can. 



By means of cin^ pictures of these workers improved methods of work 

 have been shown to a large number of workers. 



In one instance prolonged training was given to a team of girls. The 

 effects of this were : (a) improved production ; (b) improved quality ; 

 (c) definite satisfaction on the part of the workers. 



In conclusion, it may be claimed that the work has demonstrated the 

 possibilities of using a combination of time studies and motion pictures 

 for the training of future operatives in repetitive jobs. 



Mr. J. H. Mitchell. — An experiment in the selection of sales managers 

 (2-45)- 



A national sales organisation had a problem concerning the selection 

 from the sales force of managers to take charge of branches in various 

 parts of the country. The work of these managers is to control a group of 

 60 to 100 salesmen engaged in door-to-door selling of vacuum cleaners. 



After a study of successful and unsuccessful managers, a method of 

 selection was involved, based on : 



(a) History before joining company and during period as salesman. 



(b) Impressions on a rated interview. 



(c) Results of mental and temperamental tests. 



Hitherto the most successful salesmen had been appointed where 

 possible to managerial positions. It was found that there was no correlation 

 between selling abihty and managerial ability.
