Development Across the Lifespan offers a strong balance between research and applications. Robert Feldman offers students a chronological overview of physical, cognitive, social, and emotional development-from conception through death with his text Development Across the Lifespan . The text presents up-to-date coverage of theory and research, with an emphasis on the application of these concepts by students in their personal-and future professional-lives. The text taps into students' inherent interest in the subject of human development, encouraging them to draw connections between the material and their own experiences.
