What are the three main domains of aging in gerontology?

The correct answer highlights the three main domains of aging in gerontology as biological, psychological, and social aspects. These domains provide a comprehensive framework for understanding the complexities of aging.

The biological domain encompasses the physiological changes that occur as individuals age, addressing aspects such as genetics, physical health, and the physical effects of aging processes. This includes examining age-related diseases, the decline in physical abilities, and the impacts of lifestyle factors on health.

The psychological domain focuses on the mental and emotional changes associated with aging. It explores cognitive functions, emotional well-being, and mental health challenges that can arise in later life. This domain considers how aging impacts memory, resilience, and the ability to adapt to life transitions.

Finally, the social domain emphasizes the role of social interactions, relationships, and community in the lives of older adults. It examines how social factors such as support systems, societal perceptions of aging, and isolation can influence overall well-being and quality of life.

Together, these three domains provide a holistic understanding of the aging experience and inform strategies for improving the health and quality of life for older adults. Other options fail to encompass the comprehensive aspects of aging that gerontology aims to address, as they are limited to narrower themes or specific areas of study.
