ABSTRACT
This chapter describes across four sections with topics covered including: intelligence testing, classroom observations, interpretation of material, varying effects of the environment and interviewing techniques. It provides a detailed study of mental development and education in adolescent girls in the 1930’s as well as considering how important it can be to have a psychologist in the classroom. Many of the replies in the Postcard Sorting suggested that there were girls whose interests were still entirely in the concrete and personal; they were not interested in experience, but in particular experiences, they could pick out the cards they liked and disliked. But there were other girls, often of equivalent test intelligence, who could make judgments in their replies, judgments of considerable subtlety which showed that they were really interested in generalizing their experience.
