Could life experience make up for some of the effects of age on the brain? According to researchers from the School of Business Administration at the University of California, Riverside, it can and does. The research group measured a person’s decision-making ability over their entire lifespan. Using two different types of intelligence - fluid and crystallized - they found that experience and acquired knowledge from a lifetime of decision-making often offset the declining ability to learn new information. Fluid intelligence is the ability to learn and process new information. Crystallized intelligence is experience and accumulated knowledge. According to the researchers, previous studies have suggested that fluid intelligence declines as a person ages, but the studies didn’t address whether or not decision-making abilities also decline.
