In this volume are brought together the principal experimental 

 studies of animal intelligence made by Professor Thorndike, and 

 a discussion of the general laws of animal intellect and behavior, 

 which have been demonstrated by recent work in animal psychol- 

 ogy. These studies have a twofold interest. In the first place 

 since they represent the first deliberate and extended application 

 of the experimental method in animal psychology, they are a 

 most useful introduction to the later literature of that subject. 

 They mark the change from books of general argumentation on 

 the basis of common experience interpreted in terms of the faculty 

 psychology, to monographs reporting detailed and often highly 

 technical experiments interpreted in terms of original and ac- 

 quired connections between situation and response. 



In the second place, since they represent the point of view and 

 the method of present animal psychology, but in the case of very 

 general and simple problems, they are useful also as readings for 

 students who need a general acquaintance with some samples of 

 experimental work in this field. 



The work includes chapters on The Study of Consciousness 

 and The Study of Behavior ; Animal Intelligence ; The Instinctive 

 Reactions of Young Chicks ; The Psychology of Fishes ; The 

 Mental Life of the Monkeys ; Laws and Hypotheses of Behavior, 

 and the Evolution of the Human Intellect.
