Adenoids and Diseased Tonsils: Their Effect on General Intelligence

A scientific publication written in the early 20th century. This work explores the relationship between physical conditions, specifically adenoids and diseased tonsils, and the intelligence levels of children. The text aims to provide empirical evidence regarding whether these physical afflictions affect cognitive abilities in children, an area that has seen limited experimental research. The beginning of the book introduces the purpose of the study, which is to investigate the causal relationship between adenoids and diseased tonsils and lowered intelligence levels in children. It notes the medical community's growing interest in these common childhood ailments and emphasizes the need for experimental proof rather than anecdotal evidence. Rogers outlines the study's methodology, which includes a statistical analysis and a structured approach to testing children's intelligence before and after surgical intervention for their physical defects, setting the stage for a broader examination of the findings in subsequent chapters.
