Conversations With Children [PDF ebook] 

This is Volume XII of thirty-two in a collection on Developmental Psychology. Originally published in 1936, this study looks at the conversations of the authors’ own children that were recorded as they grew up. Over time they realised they were unusually rich material for investigation into child- psychology was contained in them, and despite the intimate nature of the material formulated this work.
