Final answer:
Age-related changes in general task performance include declines in physical abilities, such as stamina and strength, as well as cognitive abilities, such as fluid intelligence and memory. Engaging in mentally and physically stimulating activities can help delay cognitive decline.
Step-by-step explanation:
As individuals age, there are several age-related changes that can affect general task performance. Some of these changes include declines in stamina, strength, reflex times, and the senses. For example, muscle mass and mobility decrease, vision and hearing may decline, and reaction time slows down. Additionally, cognitive abilities can be affected, such as a decline in fluid intelligence and memory.
Research has found that engaging in mentally and physically stimulating activities can help delay cognitive decline and reduce the risk of mild cognitive impairment and dementia. It is important for older adults to stay mentally and physically active in order to maintain good physical and cognitive health as they age.
