The study of child development then and now. Child development: scientific study of processes of change and stability from conception through adolescence. Quantitative change: change in number or amount, such as in height, weight, or size of vocabulary. Qualitative change: change in kind, structure, or organization, such as the change from nonverbal to verbal communication. Along with changes such as these, people show an underlying stability, in aspects of personality and behaviour. Forerunners of the scientific study of child development were baby biographies, journals kept to record the early development of a single child. Charles darwin: first emphasized developmental nature of infant behaviour. Darwin published an abstract of his notes on his son"s sensory, cognitive and emotional development during the first 12 months. The new science of psychology taught that people could understand themselves by learning what had influenced them as children.
