LearningRx Cary: Research History
LearningRx wasn’t born overnight. In fact, our programs were developed through a process of trial and error dating back to 1968. As you’ll read on the timeline below, even significant successes weren’t enough for LearningRx founder Dr. Ken Gibson. His formula for developing the best cognitive skills training program was always the same:
Trials + Results = More Research + More Development
It took 35 years of repeating this formula with four contiguous experimental programs before Dr. Gibson finally got the fast and unprecedented gains he was after in a one-on-one brain training company. In 2002, Dr. Gibson began franchising LearningRx, and in 2014, he founded the Gibson Institute of Cognitive Research to support further research in the field of brain training.
Here is a timeline of some of the most significant research, studies (some with and some without control groups), and developments related to LearningRx programs.
(You or your child may or may not experience the same improvements described in these studies.)
