""Crossroads In The Mind Of Man: A Study Of Differentiable Mental Abilities"" is a comprehensive and scholarly work by Truman L. Kelley that explores the differentiable mental abilities of human beings. The book is divided into three parts, each of which delves into a different aspect of human cognition. The first part focuses on the nature of intelligence, including its definition, measurement, and theories of its development. The second part examines the role of language in human cognition, including the relationship between language and thought, the acquisition of language, and the different types of language processing. The third and final part of the book explores the differentiable mental abilities of humans, including perception, memory, attention, and problem-solving. Throughout the book, Kelley draws on a wide range of research in psychology, linguistics, and neuroscience to provide a comprehensive and insightful analysis of the human mind. This book is an essential resource for anyone interested in understanding the complex workings of the human mind and the differentiable mental abilities that make us uniquely human.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
