Final answer:
Older adults take longer to process, store, and retrieve new information which can be mitigated through memory techniques and mental stimulation.
Step-by-step explanation:
Older adults generally take much longer to process new information, store it, and retrieve it. This is often due to a gradual decline in fluid intelligence, which includes information processing abilities, reasoning, and memory. To combat this cognitive decline, one can use memory techniques like elaborative rehearsal, the self-reference effect, and distributed practice. Experts use methods such as rehearsing information multiple times and linking new material to pre-existing knowledge to aid in memory retention. Moreover, engaging in mentally stimulating activities can reduce cognitive decline and help maintain cognitive functions.
