Final answer:
The statement that successful aging was a uni-dimensional concept from the late 1990s is false. The idea has evolved over time, with contributions by scholars since the 1960s, acknowledging the complex interplay of biological, psychological, and social factors.
Step-by-step explanation:
The statement that successful aging was a uni-dimensional concept articulated in the late 1990s is False. The concept of successful aging has been discussed and refined over the years, with significant contributions from various scholars. In particular, Havighurst in the early 1960s already proposed ideas around 'successful aging', and the Baltes and Baltes in 1990 further developed a multidimensional perspective in their research. The understanding of aging has evolved to include a broad range of factors including biological, psychological, and social aspects. Aging is not viewed as a simplistic, single-pathway process, but rather a complex interplay of various elements that define how an individual ages 'successfully.' Understanding this intricate process requires considering diverse factors such as genetics, lifestyle, social connections, and personal attitudes toward aging.
