"In psychology there are many fruitful modes of analysis, and human nature is so complex that every possible way of studying it should be welcomed. Our own approach, which was described in the introduction to the first volume of our report, Studies in Deceit, requires the isolation of certain types of behavior, so far as these are exhibited in intelligent response to certain types of situations, for the purpose of discovering functional tendencies and their interrelations. In schematic form, the objects of our study described in Volume I are as follows: (1) Mental contents and skills--the so-called intellectual factors, (2) Desires, opinions, attitudes, motives--the so-called dynamic factors, (3) Social behavior--the performance factors, and (4) Self-control--the relation of these factors to one another and to social-self-integration. The fourth item represents the concrete reality which we hope to understand better from our study of the first three groups of facts. The present volume sets forth the methods and results of our investigation of two other types of behavior, each of which, as in the case of deceit, ranges theoretically from a condition of unsatisfactory adjustment to one of satisfactory adjustment. The first couplet, which we have for convenience called "service," contrasts work for self and work for others. The second couplet, for which we now use the term "self-control" in a special sense, contrasts the tendency to continue an approved act with resistance to the tendency to engage in an interesting but disapproved act. As we proceed various names will be attached to these behaviors, and they will be described in detail. We may refer to them tentatively as cooperation, charity, persistence, and inhibition"--Introduction. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
