Final answer:
Cognitive well-being is the domain that includes lifelong learning and developing skills, as it involves learning, memory, and creativity. This aspect of well-being is essential for maintaining cognitive abilities throughout the lifespan and contributes to positive aging.
Step-by-step explanation:
The core domain that includes lifelong learning and developing skills is Cognitive well-being. This encompasses the continuous growth in areas such as learning, attention, memory, language, thinking, reasoning, and creativity. Developmental psychologists have identified this as one of the three developmental domains where humans grow and evolve from infancy through late adulthood, alongside physical and psychosocial development.
Cognitive well-being is crucial because unlike our physical abilities, which peak in our mid-20s and then begin to decline, cognitive abilities can remain steady or even improve throughout our lives.
Activities that keep the mind active, such as learning new skills, engaging in intellectual discussions, and solving complex problems, contribute to maintaining good cognitive health and can delay the onset of cognitive decline. This domain is fundamental for psychosocial tasks, like finding meaning in life through work and family, and for elderly wellness, which encompasses social connectedness, cultural roles, and meaningful activities.
As evidenced by the lifespan development literature, fostering cognitive well-being through lifelong learning and skill development is integral to positive aging and longevity.
