The Mind of the Child, Part II: The Development of the Intellect, International Education: Series Edited by William T. Harris, Volume IX.

A scientific publication written in the late 19th century. The work focuses on the intellectual development of children during their formative years, emphasizing observations related to cognitive functions and the acquisition of language. It serves as a continuation of Preyer's earlier volume, exploring the interplay between innate abilities and environmental influences on a child's intellectual growth. The opening of the book introduces the concept that true intellectual development can occur independently of language, challenging the common belief that verbal communication is essential for thought. Preyer discusses the various stages of intellectual growth, detailing how children begin to form memory and engage in logical thought processes well before acquiring vocabulary. Through his detailed observations of his own child, as well as references to broader studies, Preyer emphasizes the importance of sensory experiences in shaping a child's cognitive abilities, laying the groundwork for a deeper examination of the development of speech in subsequent chapters.
