Science Corner Vol. 2: Working Memory Training Physically Changes Brain for the Better, fMRI Neuroimaging Study Finds

NACD Science Corner

Last summer, a group of researchers
 published a study in Frontiers in Human Neuroscience in which they
used fMRI technology to show
auditory working memory training
 (such as the auditory sequential processing activities in Simply Smarter) resulted in physical changes 
to the brain. In addition to showing
 auditory working memory can be
 trained, this research was able to demonstrate such training is more
than just learning a skill, but literally 
transforms the brain and the mind. These findings are consistent with Bob 
Doman and NACD’s 40+ years of experience in the development of tools for building processing and working memory. The researchers also found that physically altering the brain did not take very much time—only eight training sessions in 2 weeks!

Over the course of two weeks, a group of normal, healthy college students had a total of only eight training sessions that consisted of performing auditory working memory activities. Previously, they had taken part in an fMRI pretest alongside a matched control group; and at the end of the two-week training, they took part in an fMRI posttest that was conducted in the same manner as the pretest. The tests measured brain activation of all the participants as they performed auditory and visual working memory tasks and control tasks. When the fMRI posttest data was compared to pretest data, measured changes in the brain were observed in certain brain sections of the “fronto-parietal working memory network” for the treatment group but not the control group. These physical changes were also accompanied by an improvement in the performance of auditory memory tasks.

Other findings concluded that auditory training by itself did not significantly enhance visual functioning and vice versa, which is again consistent with NACD’s methodology of addressing both auditory and visual sequential processing.
