606 SECTIONAL TRANSACTIONS.— J. 



Just as we distinguish general, group and special abilities, so we may distinguish 

 general, group and special educabUities. Occupations involving high-level abilities 

 rightly demand a wide education, followed by an increasingly specialised training ; 

 whereas the training for occupations involving low-level abilities should be initially 

 specific, proceeding, so far as is possible (considering here the limitations of intelligence), 

 in the reverse direction. Experimental evidence indicates that low-level motor 

 abilities show no correlation with one another, whereas the more highly co-ordinated 

 motor abiUties fall into groups, the members of which are inter-related. This and 

 their changing correlation with practice have an obvious bearing on the problems of 

 training and trainability. 



Mr. R. J. Mackay .—Some Human Aspects of Industrial Rationalisation. 



The term ' Industrial Rationalisation ' connotes the efficient localisation and 

 route-Lng of human power. Some results of experiments with vocational tests in an 

 industrial concern. Need for well-informed vocational guidance bureaux. The 

 further extension of ' Rationalisation ' should provide channels for the more suitable 

 placing of all grades of personnel. We may expect a growing industrial and com- 

 mercial absorption of types normally regarded as ' professional,' including a stronger 

 demand and more equitable reward for the scientific worker.

Dr. W. Brown. — Personality and Methods of Mental Analysis. 



The structural and d5mamic characteristics of personality have been studied and 

 elucidated in recent years by special methods of mental analysis — on the one hand by 

 quantitative methods (statistical correlations), and on the other by the qualitative 

 methods of hypnotism, psycho-analysis and other forms of what may be called ' deep 

 analysis.' In each case the inferences drawn from the method need to be carefully 

 distinguished from the method itself, and in several the influence of the experimenter 

 upon the subject needs close scrutiny and careful assessment. A definition of 

 personality and an indication of its general structure in the light of modem knowledge.

 Dr. J. Drever.— Errors in Spelling. 



Mr. A. R. Knight. — The Psychological Make-up of the Business Executive. 



Mr. A. Hudson Davies. — A Method of comparing Abilities in Colour- 

 matching. 



The method described was devised for purposes of research on selection tests 

 for printing operatives. Ordinary tests for colour-defect are not suitable for selec- 

 tion purposes, since the nature of a colour-printer's work soon discovers crude
