Our In-Depth Research & Development
Over Three Decades of Brain Training & Testing
LearningRx® wasn’t born overnight. In fact, the company and its programs encompass a long development 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 that Dr. Gibson finally got the fast and unprecedented gains he was after in a one-on-one brain training company. Here is a timeline of some of the most significant research, studies (some with and some without control groups), and developments related to his work in cognitive skills training.

The Launch of Master The Code, the Foundation Of ReadRx (2000-2001)
2001 — Dr. Gibson analyzes the results of studies using PACE and the Master the Code (MTC) Reading Program, reporting gains of 4.8 years on the Woodcock-Johnson Tests of Cognitive Abilities, 6.1 years on the Woodcock Reading Mastery Tests of Visual-Auditory Learning, a 2.7-year gain on the Woodcock Reading Mastery Word Attack Test, and 3.4 years on the Lindamood Auditory Conceptualization Test.
2000 — Dr. Gibson creates the Master the Code (MTC) Reading Program based on the research from a 10-year federal government $60 million project to gather the results of 130 reading programs.
The Birth of PACE—Processing And Cognitive Enhancement (1994-1999)
1998 — Dr. Gibson takes PACE to Florida, training six fourth- and fifth-graders at Jubilee Christian Academy in Pensacola. The control study examines cognitive skills improvements in the Detroit Tests of Learning Aptitude-3 after 30 hours of PACE training. The results for the experimental group show gains in visual processing of 2.7 years, memory of 3.9 years, and auditory processing of 3.9 years compared to the control group gains of 2.3, 1.0, and 1.0 years respectively. After the fourth- and fifth-graders completed their training, they each trained a first-grade student for one hour per day for eight weeks. The six first-graders in the control group (no training) had average gains of 1.0, 1.5, and 1.5 years for visual processing, memory, and auditory processing respectively whereas the four first-graders receiving training had average gains of 3.8, 2.9, and 2.9 years for visual processing, memory, and auditory processing respectively.
1997 — A study of 166 children and adults who completed PACE training finds increased post-test gains when using TONI-2 measurements. The average change in nonverbal IQ score for 103 clients whose pre-test scores were below age was 2.93 years. The average change in nonverbal IQ score for the 63 clients whose pre-test scores were two or more years below age was 3.28 years.
1996 — A study of 174 children and adults who completed PACE training finds increased post-test gains when using TONI-2 measurements. The average change in nonverbal IQ score for the 65 clients whose pre-test score was greater than 100 was 9.89 points. The average change in nonverbal IQ score for the 91 clients whose pre-test score was less or equal to 100 was 28.15 points.
1995 — Dr. Gibson evaluates the pre- and post-test data from an optometrist in Great Falls, Montana, who used the visual processing and cognitive training program. Of the clients whose cognitive skills were scored “below age” on the pre-test, there is an average nonverbal IQ score increase of 3.12 years. For those clients whose cognitive skills were scored “two or more years below age” on the pre-test, there is an average nonverbal IQ score increase of 4.55 years.
1995 — Using the pre- and post-test data from both VIP and PACE clients, Dr. Gibson writes a report on the effectiveness of the VIP and PACE Cognitive and Processing Training Programs. (Both programs are 10 weeks in length consisting of 30 hours of one-on-one training and prescribed home activities.) For the first time, results are measured using IQ tests. The results of the TONI-2 (Test of Nonverbal Intelligence) measure a 15-point increase in IQ score, and the Structure of Intelligence (SOI) and the Detroit Test of Learning Aptitudes measure a 12- to 15-point increase in IQ score. The report also includes data from a small controlled study (n = 37) showing composite gains of 2.2 years with a treatment group in Indiana and 2.8 years with a group in Illinois, versus no gains in the control group.
1994 — Testing is upgraded to nationally recognized tools like the Woodcock-Johnson tests, the Comprehensive Test of Phonological Processing (CTOPP), and the Detroit Test of Learning Aptitude.
1994 — Dr. Gibson collaborates with Doug Smith, PhD. of the Department of Psychology of Southern Illinois University, to do a study on cognitive training.
1994 — After reviewing the results of the VIP program over the past seven years and learning much more about cognitive skills, Dr. Gibson decides to develop a new program that eliminated some visual procedures but added auditory processing, long- and short-term memory, and logic and reasoning training. The new program is called PACE: Processing And Cognitive Enhancement, and it is initially introduced exclusively through psychologists. The results are impressive—beyond anything to date—so PACE is later opened to physicians, educators, optometrists, and others.
Assembling a Team of Cognitive and Motor Skills Experts (1975-1993)
1992 — Dr. Gibson does an observational study of 35 clients’ pre- and post-test data sent (from optometrists) using the TONI-2. Again, the results show remarkable improvement in cognitive skills.
In addition, he uses a five-point scale to include the clients’ parents’ observations (i.e., subjective measurement). These included the effectiveness of the program (3.9), the value in terms of time and money (4.0), and the rating on learning (attention = 3.7, behavior = 3.4, accuracy = 3.6, speed = 3.6, energy = 3.6, and self-esteem = 4.1).
1988 — After collecting data on 288 clients from eight of the optometrists using the VIP Program, Dr. Gibson discovered that the program was increasing IQ score (using TONI-2: Test Of Nonverbal Intelligence). However, he saw only minimal improvement in reading, which pushes Dr. Gibson to do more research on reading.
1986 — Incorporating everything he has learned over the one-year hiatus, Dr. Gibson launches the Vision Improvement Program (VIP), a 10-week, 30-hour program of mostly visual processing with some traditional visual therapy. Using four different measures (including the SOI-LA Structure of Intellect and Learning Abilities Test) to measure short-term memory, logic, visual-motor, processing speed, and selective attention, Dr. Gibson determines that his program is resulting in an average of 2.9 skill years of improvement. This is twice the improvement of the previous program, but within one-quarter of the time. Other optometrists begin to learn about the impressive results and eventually, Dr. Gibson licenses the program to more than 200 optometrists in the U.S.
1985: As part of his research and continued pursuit of excellence in the field of cognitive skills training, Dr. Gibson learns from Dr. Robert Pepper, the optometrist for the Portland Trailblazers, who introduces him to the importance of loading and adding intensity to the training of specific skills. This, combined with sequencing, immediate feedback, targeting specific skills, and making sure training is fun had been the hallmark of Dr. Gibson’s cognitive training.
1985 — Unhappy with the program being just “better than average,” Dr. Gibson discontinues his learning center for an entire year to do more research. The research includes three main components: reading research, studying training methods, and understanding computer games.
1975 — Despite the impressive reading gains at his chain of preschools, Dr. Gibson is convinced that there is more room to improve other cognitive skills involved in learning. He assembles a team of experts—in auditory processing, fine motor skills, and early education—to complement his expertise in visual processing and visual training. Together, the team develops a strong program in perception and sensory-motor training and they open The Learning Center. The results showed about twice the gain as what was being achieved in the average special education program.
The Early Years: Trial and Error (1968-1974)
1972 — Dr. Gibson begins looking at preschools for his daughter Kim. When he is unable to find anything that he feels will advance her learning, he starts his own preschool using teaching machines, sensory-motor training, and a reading program. The preschoolers who were in the program for two years entered kindergarten reading at a second-grade level.
1968 — Dr. Gibson opens his first pediatric optometry practice with the goal of helping kids with learning and reading problems. He soon learns that only a small percentage of children’s learning struggles are caused by poor vision. He then starts researching how we process visual information.
