| Subject: Are Commercial Brain-Training Programs Worth It? Tue Jun 21, 2016 6:11 am | |
| MONDAY, June 20, 2016 (HealthDay News) -- Brain-training programs like Lumosity or NeuroNation frequently tout scientific studies that show their products can truly sharpen a person's intellect.
But at least some of these alleged benefits might be due to a fleeting placebo effect, a new study suggests.
If people are told they are participating in a brain-boosting study, they wind up performing 5 to 10 points better on follow-up IQ tests than those left in the dark about the possible mental benefits of the exercise, researchers report.
"We think this is very strong evidence that placebo effects can lead to positive outcomes, as opposed to the training leading to positive outcomes," said lead researcher Cyrus Foroughi, a doctoral student with the department of psychology at George Mason University, in Fairfax, Va.
