Working memory training is intended to improve a person's working memory. Working memory is a central intellectual faculty, linked to IQ, ageing, and mental health. It has been claimed that working memory training programs are effective means, not only for treating attention-deficit/hyperactivity disorder (ADHD) and other cognitive disorders, but to improve intelligence and to enhance cognitive functioning in typically developing children and healthy adults. 23 studies with 30 group comparisons, show that clinical memory training programs produce reliable short-term improvements in working memory skills in children and adults with ADHD. Yet, the study results differ with regard to conclusive evidence that such effects can be maintained long-term without additional follow-up training. There is also no convincing evidence of the effect of working memory training to other skills such as nonverbal and verbal ability, inhibitory processes in attention, word decoding, and arithmetic. While most studies show clinical relevance of working memory training programs for ADHD population, they cast doubt that these program should be considered as methods of enhancing cognitive functioning in children and adults without working memory deficiencies.
