This book contains a detailed manual for the use of the 'Rorschach test' in large groups, and for multiple choice. It includes instructions for the procedure and details of scoring, as well as outcomes of numerous historical studies which have endeavored to ascertain their validity. “Large Scale Rorschach Techniques” will appeal to those with a practical interest in psychological testing, and would make for a great addition to collections of allied literature. The Rorschach test is a psychological test in which subjects' perceptions of inkblots are recorded and then analyzed using psychological interpretation, complex algorithms, or both. It has been employed to detect underlying thought disorder, especially in cases where patients are reluctant to describe their thinking processes openly. Many antiquarian texts such as this are becoming increasingly rare and expensive, and it is with this in mind, that we are republishing “Large Scale Rorschach Techniques” now in an affordable, modern, high-quality edition. It comes complete with a specially commissioned new biography of the author. This book was first published in 1922.
