There are approximately one billion adult illiterates in the world. Adult literacy programs in developing countries are often ineffectual and rather limited outcomes. To improve outcomes, much emphasis has been given to empowering nongovernmental organizations, increasing learner motivation, and reinforcing social benefits. This book summarizes the pertinent cognitive and neuropsychological research using layman terms and attempts to apply it to the acquisition of adult literacy. It presents issues and ideas on designing adult literacy programs that support human memory functions as understood in 2003.
