The Psychology of Individual Differences
For a number of years the writer has given courses on the psychology of individual differences to students in liberal arts and in education who wished to obtain a general knowledge of individual differences without the necessity of taking several courses in statistics and mental measurement. This volume is directly the outgrowth of that experience. It aims to give, especially for the benefit of the elementary student, an introduction to the problems, the methods, the results, and the applications of the psychology of individual differences. The point of view is essentially biological, experimental, and statistical, and but little attention has been given to pathology and psychoanalysis. Individual differences in acquired traits are discussed to some extent, but the field primarily considered is differences in native traits.
