The study, published online Tuesday by the journal Nature, tracked 11,430 participants through a six-week online study. The participants were divided into three groups: the first group undertook basic reasoning, planning and problem-solving activities (such as choosing the “odd one out” of a group of four objects); the second completed more complex exercises of memory, attention, math and visual-spatial processing, which were designed to mimic popular “brain-training” computer games and programs; and the control group was asked to use the Internet to research answers to trivia questions.-
Ummm, that’s a horrid “control”, as they are also exercising higher brain functions. A better one would be watching TV or ideally, doing nothing during the training time.
