"...'youth' as an area of academic research emerged...in 1904, when social psychologist G. Stanley Hall wrote his pathbreaking two-volume tome Adolescence: Its Psychology, and Its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion, and Education, which may be credited as the beginning of youth studies..../Of course children and teenagers existed before the twentieth century began, but the social perception of the preadult population was considerably different before the early 1900s....As the modern era took hold, certain researchers like Hall (and later Havighurst, Piaget, Winnicott, Erikson, and Anna Freud) began recognizing a distinct age of specialized development between childhood and adulthood that had been initially described through characteristics of sexual development and was then later examined as a more complex sociopsychological manifestation of cultural and internal conflict."
