In so doing, they review important research on cognitive functioning, behavioral processes, personality and identity development, and overall well‑being in middle to late adulthood.   Diehl and Wahl’s three-part framework helps readers better understand that the development process is influenced by multiple factors and can take many different trajectories. Through this contextualized perspective, they examine the influence that previous life experiences, beginning in early childhood, can have on the aging process in older adults. This includes social relations, technological advances, societal perspectives on aging, and education. The authors also examine the challenges and opportunities of aging, using a strength‑based approach to promote a diverse, nuanced understanding of successful, healthy aging.   Chapters also conclude with dialogues from other experts in the field, offering multiple different perspectives on the research.
