What The Research Says

Hear from those who have studied N-Back.

Jacky AU

National Library of Medicine

"We included 20 studies in our analyses that met our criteria and found a small but significant positive effect of nback training on improving fluide intelligence."

Dan Hurley

The New York Times

"In a follow-up to their 2008 study in young adults, Jaeggi, Buschkuehl and their colleagues published a paper last year that described the effects of N-back training in 76 elementary- and middle-school children from a broad range of social and economic backgrounds. Only those children who improved substantially on the N-back training had gains in fluid intelligence."

Tiina Salminen

Nature

"After 16 training sessions, the dual n-back training group showed improved performance accompanied by increased functional connectivity of the ventral DMN in the right inferior frontal gyrus, which correlated with improvements in working memory."
