Deficiency and Delinquency: An Interpretation of Mental Testing

In undertaking in 1912 to examine the mental development of delinquents for the clinic started and supported by the Juvenile Protective League of Minneapolis, in connection with the Juvenile Court, I soon became convinced that a safer method for evaluating the limit of feeble-...

11. CHAPTER I. INTRODUCTION

As an interpretation of the results which have been obtained with mental tests, this book lies between the topics of deficiency and delinquency. It is an attempt to discover the...

12. CHAPTER II. THE FUNCTIONS OF A SCALE IN DIAGNOSIS

Whatever form the definition of feeble-mindedness may take, in this country at least[3] the concept has become quite firmly established as describing the condition of those who...

13. CHAPTER III. THE PERCENTAGE DEFINITION OF INTELLECTUAL DEFICIENCY

In order to direct attention to the quantitative description of intellectual deficiency which is here proposed, let us state the percentage definition in its most general form....

14. CHAPTER IV. WHAT PERCENTAGE IS FEEBLE-MINDED

At first it seems like a hopeless task to try to bring harmony out of the confused estimates of the proportion of the feeble-minded in modern society. Authoritative estimates by...

15. CHAPTER V. ADAPTING THE PERCENTAGE DEFINITION TO THE BINET SCALE

Sufficiently large random groups have not been tested with any development scale to make the determination of the borderline on the scale more than tentative. Such borderlines m...

16. CHAPTER VI. DELINQUENTS TESTING DEFICIENT

We are now in a position to evaluate the Binet examinations of delinquents. Let us first note our results for a group of 123 consecutive cases at the Hennepin County Detention H...

17. CHAPTER VII. CHECKING THE BINET DIAGNOSIS BY OTHER METHODS

The Binet scale in its various forms provides only part of the objective evidence as to the mental inferiority of delinquents, although it affords the best means at present of i...

18. CHAPTER VIII. SCHOOL RETARDATION AMONG DELINQUENTS

Besides the estimates of deficiency based on tests, the school records may furnish valuable objective evidence about mental retardation among delinquents. The school environment...

19. CHAPTER IX. COMPARISON OF THE SCHOOL TEST AND THE BINET TEST

There has been considerable discussion of the question whether psychological testing should be expected to conform to the ranking of pupils in school. This discussion however, d...

20. CHAPTER X. BAD SCHOOL ADJUSTMENT AS A CAUSE OF DELINQUENCY

The comparison of the Binet and school tests for our group of serious delinquents suggests another important comparison. Many delinquents are found to be apparently wrongly plac...

21. CHAPTER XI. DEFICIENCY AS A CAUSE OF DELINQUENCY

In a preceding chapter we have shown the frequency of tested deficiency among various types of delinquents. We may now further consider the significance of this association of d...

22. CHAPTER XII. SUMMARY AND SUGGESTIONS

1. In our attempt to interpret the volume of results concerning tested delinquents, we have accepted the common conception that the feeble-minded are those who, through lack of...

23. CHAPTER XIII. THE THEORY OF THE MEASUREMENT OF MENTAL DEVELOPMENT

In defining the borderline of feeble-mindedness it will be found that certain assumptions are usually tacitly made as to the form of the curves of normal and retarded developmen...

24. CHAPTER XIV. QUANTITATIVE DEFINITIONS OF THE BORDERLINE

On the basis of the detailed conception of the developmental curves and distributions of ability at different ages, which we have been considering, we can now compare the percen...
