The third edition of Infancy is a comprehensive and accessible core text for courses in infant development and early childhood development. Gross guides students through a child's developmental stages from birth and up to the first three years of life. Rich in research, the text explores the role of infant development studies and highlights how far we have come in our understanding of a child's first years. Gross's sensitive and engaging teaching voice seamlessly weaves together research and theory with current issues of diversity and culture, prompting students to apply concepts to their own lives and explore the broader implications upon public policies. Updates to the Third Edition include: - Chapter 7 has been split into two separate chapters on play and learning, and cognitive science, respectively. - Chapter 12 has been folded into the other chapters to better integrate the content on music, media, and technology. - A new design highlights updated figures and tables, engaging chapter-opening vignettes, and other pedagogy. - Revised ancillaries include an instructor's manual and test bank as well as new PowerPoint slides and a new Companion Website for students.
