Researchers at the University of Oslo in Norway examined working-memory treatments across 23 different studies. They found that working-memory training improved performance on tasks related to the training itself, but did not affect more general cognitive performance, such as verbal skills, attention, reading or arithmetic. The findings suggest that working-memory training does not improve cognition, boost IQ or improve attention-deficit hyperactivity disorder or dyslexia.
