Question

Crystallized intelligence, which is the accumulation of knowledge and skills gained through experience, does increase steadily over the adult years and declines only modestly in late adulthood. In contrast, fluid intelligence, which involves abstract reasoning and problem-solving skills, tends to peak in early adulthood and decline gradually thereafter. Selective attention, the ability to focus on one task while ignoring distractions, may become more difficult with age, while divided attention, the ability to attend to and process multiple streams of information, may actually improve with practice and experience. Finally, the capacity of working memory, the ability to hold and manipulate information in the mind for brief periods of time, generally declines with age.
