Psychological scientist Dr. Randall Engle of the Georgia Institute of Technology published new research in the Oct. 8, 2013, edition of the journal Psychological Science that proves there is no gain in intelligence from “brain training” programs.
Brain training does increase working memory capacity and can lead to improvements in memory, the speed of memory recall, the ability to eliminate distractions when concentrating, and the ability to multitask. Brain training cannot increase a person’s innate ability to reason, the ability to produce novel solutions to complex problems, or the ability to infer relationships between pairs of variables or groups of variables.
Engle tested his theory on 55 undergraduate students. The participants underwent a 23 day regimen of brain training. All participants were paid to assure maximum attention was given to the training.
No method of brain training increased or improved intelligence. Brain training was found to be most effective in producing higher levels of multitasking ability during distractions in the trial participants.
The research indicates you are born with the intelligence you have and cannot increase it. You can increase knowledge. Brain training does increase memory ability and the capacity to perform more than one task at a time successfully even while being distracted.
