Changes in Mental Traits with Age Determined by Annual Re-Tests is a book written by Brooks Fowler Dell in 1921. The book examines the changes in mental traits that occur as people age, using annual re-tests to track these changes over time. The author presents data and analysis from a study of over 200 individuals, ranging in age from 10 to 70 years old, who were tested annually for a period of 10 years. The book explores various mental traits, such as memory, attention, and reasoning ability, and how these traits change over time. The author also discusses the implications of these changes for education and other areas of life. This book provides valuable insights into the aging process and how it affects cognitive abilities, making it a useful resource for researchers, educators, and anyone interested in understanding the human mind.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
