In the first part of the book the authors deal extensively with the development of the group Rorschach method, stressing its merit as a time-saving device and citing evidence from other investigators as to its value in the classification, selection and screening of maladjusted persons. Adequate directions for administration and for scoring are given, and numerous illustrations appear.
The second part of the book, in which an analysis of the findings of an experimental investigation is presented, is much less convincing, from both the statistical and the clinical viewpoint. The statistical procedure open to most serious challenge is the small and poorly selected sample of subjects used for standardization purposes, involving, as it does, a college group in which more than one half are medical students and nurses. With the individual Rorschach method, such a professional group is generally conceded to report more than the usual number of anatomic responses.
