By Dr. JOHN B. WATSON, 



Professor of Psychology, Johns Hopkins University, Baltimore. 



429 Pages. lUustrated. $8.00. 



HIGH AND ADTANCED SCHOOLS. 



A TEXT FROni THE MODERN VIEWPOINT: — Every teacher of Psychology, whether 

 or not he may favor the study of the subject from the objective standpoint, will read it 

 with profound interest. From beginning to end a constructive attitude is maintained and, 

 where possible, the material employed has been gathered by objective methods. No field, 

 however, at present belonging to psychology, is neglected. 



The text takes the position that psychology is a scientiflo study of human behavior, of 

 the acts that man does through his original nature and hence apart from training, the acts 

 which he can later do by reason of the putting on and retaining suitable habits. The 

 importance of studying the individual in the light of his instructive equipment, the en- 

 vironment in which he has had to grow up, the system of habit which he has had to put 

 on, and the stability of his emotional life are all emphasized. 



The illustrations in the anatomical section have been prepared with great care and a 

 number of the drawings were made under the direct supervision of Max Broedel.

 thorough course in psychology, is not adequately treated in general texts. This volume 

 covers the subject in a broad and systematic way and is a suitable textbook for courses in 

 child psycholgy, mental diagnosis, mental development and education of children. It is of 

 special value to teachers and school administrators, as it gives a thorough discussion of 

 many of their fundamental problems. It gives the student an understanding of just how 

 the most modern applications are made, in some very important instances, and a definite 

 idea of the results achieved. The volume makes an excellent text tor supplementing a 

 course in general psychology or in any special branch where the scientific treatment of 

 intelligence is regarded as important.
