New work involving leading UK neuropsychologist Susan Gathercole indicates that brain training has no lasting effects.
Based on claims that this could enhance IQ, reading and math, the researchers randomized children to intensive "brain training" of working memory. The trial was large (over 450 6-year olds) and well controlled, and at one and two year follow ups found… "no improvements in reading, spelling or mathematics".
WM training is being urged (and even paid for) as an intervention for children. The new data say this should end.

Some research has shown small associations between "grit" and academic achievement. These have been from small, selected samples, but the results have been widely cited as showing that "Grit outweighs IQ". What do large, well controlled studies suggest?
A new paper from the lab of lifetime awardee Robert Plomin and written by 2014 prize winner Kaili Rimfeld, data from 4,500 16-year-old twins show that grit predicted just one half of one percent (0.5%) of variance in high-stakes school results. This was dwarfed by the effects of IQ. Conscientiousness and ...
ISIR researchers Dr Rosalind Arden and Dr Mark J Adams have been studying intelligence in dogs, with fascinating symmetries between human and dog IQ suggesting that dogs may be good participants for research on IQ and perhaps research on preventing dementia (if dog-IQ scores could be used as a marker of cognitive decline in our sadly shorter-lived friends).
Food writer Felicity Cloack thought the idea interesting enough to run her own in-house replication and present the research through this lens to Guardian readers. Worth a read!
ISIR president-elect Rich Haier discusses brain-imaging, genetics, the environment, and the future of IQ with psychology today.
Biosketch: Ruth examines high-IQ as a potential risk factor for various disorders and diseases. She is especially interested in studying and advocating for those who possess dual exceptionalities in intellectual ability and disability.
Her present research involves the recruitment of over 3700 American Mensa members, who test within or above the 98th percentile of intelligence, to examine a potential interplay between high cognitive ability, affective disorders (mood and anxiety), and immune and inflammatory dysregulations such as allergies, autoimmune disease and ...
