Experimental Studies of Mental Defectives is a book written by John Edward Wallace Wallin in 1912. The book is a critique of the Binet-Simon tests, which were widely used at the time to measure intelligence in children. Wallin argues that the tests are flawed and do not accurately measure intelligence in children with mental disabilities.In addition to his critique of the Binet-Simon tests, Wallin also provides a contribution to the psychology of epilepsy. He conducts a series of experiments on children with epilepsy and analyzes their mental abilities. Wallin's research suggests that children with epilepsy may have different cognitive processes than children without epilepsy.The book is divided into several sections, each focusing on a different aspect of Wallin's research. He begins by discussing the history and development of the Binet-Simon tests, and then critiques their validity. Wallin then moves on to his experiments with children with epilepsy, discussing his methods and findings.Overall, Experimental Studies of Mental Defectives is an important work in the history of psychology. Wallin's critique of the Binet-Simon tests helped pave the way for the development of more accurate intelligence tests, and his research on epilepsy contributed to a better understanding of the condition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
