Life-Span Human Development

Life-Span Human Development, 9th Edition, is a textbook that examines developmental trends and influences across the life span. Authors Carol K. Sigelman and Elizabeth A. Rider trace growth, change, and key transformations from infancy to old age.

The volume combines a topical structure at the chapter level with an age and stage organization within each chapter. Every chapter addresses a specific developmental domain, such as physical growth, cognition, or personality, and traces progress through dedicated sections for infancy, childhood, adolescence, and adulthood.

Coverage emphasizes developmental theories, their practical applications, and the interaction of nature and nurture. The 2018 edition incorporates updated research on biological and sociocultural influences alongside media resources designed to support active learning.
