Frontiers in Education, 2(62). doi: 10.3389/feduc.2017.00062 This study with 178 students ages 5-18 investigated whether ThinkRx and ReadRx clinician-delivered cognitive training programs reduced academic difficulties and oppositional behavior for school-age children with learning struggles compared to a control group. Results indicated there were statistically significant differences overall between the intervention groups and the control group on all measures of academic difficulties. Both intervention groups saw a reduction in academic difficulty ratings following training while the control group saw an increase in academic difficulty during a comparable time interval. Both intervention groups achieved statistically significant changes on objective cognitive test measures as well. Link to study: https://www.frontiersin.org/articles/10.3389/feduc.2017.00062/full

The current study examined the cognitive outcomes following ThinkRx, a clinician-delivered cognitive rehabilitation training program for soldiers recovering from traumatic brain injury (TBI) and acquired brain injury (ABI). In a retrospective chart review, we examined cognitive outcomes of 11 cases who had completed an average of 80 hours of ThinkRx cognitive rehabilitation training delivered by clinicians and supplemented with digital training exercises. Outcome measures included scores from six cognitive skill batteries on the Woodcock Johnson – III Tests of Cognitive Abilities. Participants achieved gains in all cognitive skills tested and achieved statistically significant changes in long-term memory, processing speed, auditory processing, and fluid reasoning with very large effect sizes. Clinically significant changes in multiple cognitive skills were also noted across cases. Link to article: http://journal.frontiersin.org/article/10.3389/fpsyg.2017.00825/full

In a randomized controlled study, the effects of a one-on-one cognitive training program on IQ, memory, visual and auditory processing, processing speed, reasoning, and attention for students ages 8-14 were examined. Participants were randomly assigned to either an experimental group to complete 60 hours of cognitive training or to a wait-list control group. The purpose of the study was to examine changes in general intelligence and individual cognitive skills after completing cognitive training with ThinkRx, a LearningRx program. Results showed statistically significant differences between groups on all outcome measures except for attention. Implications, limitations, and suggestions for future research are examined.

Journal of Experimental Education: Learning, Instruction, and Cognition, 84(3), 600-620. doi: 10.1080/00220973.2015.1065218. This article describes two trials testing the efficacy of the LearningRx one-on-one cognitive training program and its computer-based version (Brainskills) in laboratory and school settings. Study 1 tested Brainskills in a laboratory setting with 322 middle school students. Paired t-tests revealed significant gains on all cognitive measures and math performance after 3 weeks of training. Study 2, a randomized control study, included 225 high school students randomly assigned to one of three conditions: LearningRx, Brainskills, or study hall (control) in a school setting for a 15-week training period. Univariate ANCOVAs revealed significantly higher scores for the treatment groups compared with controls on working memory, logic and reasoning, and three of four math attitude measures.

The purpose of this study was to investigate the effectiveness of the comprehensive cognitive training program, ThinkRx. Sixty-one children (ages 6-18) were given pretest and post-test cognitive assessments. Thirty-one students completed a 24-week cognitive training program in a LearningRx center. A matched control group of thirty children did not receive training. Multiple regression analyses indicated that treatment group membership was a statistically significant predictor of outcomes in long-term memory, logic and reasoning, working memory, processing speed, auditory processing, and Word Attack. The treatment group realized significantly greater gains in six of seven cognitive measures. Link to study: http://www.covd.org/?page=VDR_1_2
Moore, A.L., Carpenter, D.M., Ledbetter, C., & Miller, T.M. (2016). Clinician-delivered cognitive training for children with ADHD: Transfer effects on cognitive and behavior from the ThinkRx randomized controlled trial. Manuscript in second peer review.
In a randomized controlled study, we examined the effects of a one-on-one cognitive training program on memory, visual and auditory processing, processing speed, reasoning, attention, overall IQ score, and behavior for students ages 8-14 with ADHD. Results included greater pretest to post-test change scores on all variables for the treatment group versus the control group with statistically significant differences noted in working memory, long-term memory, logic and reasoning, auditory processing, and IQ score. Qualitative outcomes included far transfer to cognition and behavior as reported by participants, parents, and clinicians.
Moore, A.L., Carpenter, D.M., Miller, T.M., & Ledbetter, C., (2017). Transfer Effects from Two Methods of Delivering Cognitive Training to Children with Learning Struggles: A Randomized Controlled Trial. Manuscript in peer review.
In a randomized controlled trial assessing equivalence of parallel groups of children ages 8-14, we compared cognitive and behavioral outcomes between a group who received 60 hours of ThinkRx cognitive training delivered one-on-one by a clinician (n = 20) versus a group of children who received 30 hours of ThinkRx delivered by a clinician and the remaining 30 hours through digital training procedures (n = 18). Results showed no significant differences between groups on tests of working memory, logic and reasoning, auditory processing, visual processing, processing speed, or overall IQ score. Behavioral outcomes were similar between both delivery methods. These results suggest that both delivery models are efficacious interventions for children with learning struggles.
Moore, A.L., Ledbetter, C., & Carpenter, D. (2017). MRI and neuropsychological outcomes following cognitive rehabilitation training in traumatic brain injury: A Multiple case study. Presented at Society for Neuroscience, November 2017, Washington, DC.
Using a multiple case study design, we examined neural connectivity changes with fMRI and changes in IQ score, working memory, long-term memory, visual & auditory processing, processing speed, attention, reasoning, and everyday functioning following 60 hours of cognitive training for 5 clients with Traumatic Brain Injury. Results from the Woodcock Johnson IV -Tests of Cognitive Abilities showed increases in IQ score for all cases (n = 5), with a mean increase of 21 points. All cases achieved gains in long-term memory, processing speed, logic and reasoning, and auditory processing; and four of five cases gained on visual processing and working memory. mTBI participants exhibited significant training-induced changes in neural connectivity. Normalization of the Default Mode Network (DMN) was evident in the severe TBI case along with the appearance of anti-correlations and decreased hyperconnectivity.
Moore, A.L., & Ledbetter, C. (2017). Beyond Attention: Memory and Processing Speed Deficits Dominate Cognitive Profiles in ADHD Across the Lifespan. Presented at American Psychological Association Annual Convention, August 2017, Washington, D.C.
The objective of this study was to examine the cognitive profiles of a large sample of children and adults with Attention Deficit Hyperactivity Disorder (n = 5,417). We collected scores on the Woodcock Johnson III – Tests of Cognitive Abilities administered to children and adults with ADHD at 79 cognitive therapy centers between 2010 and 2015. Deficits were identified in comparison to the standardization sample as standard scores under the 38th percentile. Results indicated that although deficits in broad attention were present, there were even larger deficits in working memory, long-term memory, and processing speed. The results suggest that interventions for children and adults with ADHD should be aimed at not only the remediation of attentional difficulties but also at enhancing memory and processing speed.

Ledbetter, C., Faison, M.O., & Patterson, J. (2016). Correlation of cognitive training gains and resting state functional connectivity. Presented at Society for Neuroscience, November 2016, San Diego, CA.
In a randomized controlled trial, 30 high school students were randomly assigned to ThinkRx cognitive training (n = 11), Brainskills digital training (n = 12), or a control group (n = 7). Resting state MRI results showed training-induced gains in global efficiency associated with visual processing, auditory processing, contextual associations, the default mode network, and the cerebellum. For all seven cognitive skills measured, changes in resting state functional connections correlated with changes in performance on the test. Link to results
Moore, A.L., Ledbetter, C., & Carpenter, D.M. (2016). Intensive, metronome-based, 1-on-1 cognitive training improves cognitive skills in children. Presented at Society for Neuroscience, November 2016, San Diego, CA.
In a 2-phase randomized controlled trial, we examined the efficacy of ThinkRx cognitive training on IQ score, working memory, long-term memory, visual & auditory processing, processing speed, and reasoning for children ages 8-14 in a clinic setting. Then, we examined the differences between two methods of delivering ThinkRx. Phase 1 training effects included significant pretest to post-test gains on all measures, and a mean gain of 21 points in IQ score for the trained group. Phase 2 training effects included significant pretest to post-test gains on all measures, and a mean gain of 22 points in IQ score for the second trained group. Pairwise comparisons only indicated a significant difference between the two delivery methods on long-term memory. Link to results
DISSERTATIONS AND TECHNICAL REPORTS
Moore, A. (2015). Achievement Outcomes for LearningRx Students: Math and Reading Achievement Before and After Cognitive Training.
This study analyzed reading and math achievement outcomes for more than 6,000 students who completed a ReadRx or MathRx training program at LearningRx between 2008 and 2014. To assess differential effects of each program and to control for placebo effects, the ReadRx students served as the control group for the MathRx program and the MathRx students served as the control group for the ReadRx program. We measured the opposite skills from which the students were trained. The MathRx students made twice the gains in math and the ReadRx students made twice the gains in reading. In a subset of students who provided state reading achievement test results, 91% percent of the students who completed the ReadRx program showed improvement on state reading achievement tests after the intervention. See the results of the study.
Doctoral Dissertation Examines Real-Life Benefits of Cognitive Training
Dr. Edward Jedlicka used an observational survey completed by parents to evaluate whether LearningRx brain training produced noticeable, real-life improvements in their children, especially in the areas of cognitive skills, academic success, and oppositional behavior. Read the dissertation. Associated manuscript was published in 2017.
Doctoral Dissertation Examines the Profiles of Cognitive Trainers Associated with Success for Students
Dr. Amy Moore studied characteristics of 150 cognitive trainers that predicted outcomes for 1,195 clients with and without ADHD. After examining the predictive value of trainer personality, degree level, degree field, certification level, and pre-hire cognitive screening score on client gains in long-term memory, working memory, processing speed, and general intelligence, she found that no trainer profile held practical significance. Dr. Moore concluded that the intervention itself may be more important than the characteristics of the person delivering it. Read the dissertation.
