Research

Research has been an integral part of MindBlaster since its beginning in the late 1990s. All students are given extensive testing before and after the 10-week program to determine if the training has been effective and to provide information that the APPA psychologists can use to make MindBlaster even better. Research has focused on: (1) the students’ performances at the time of graduation from MindBlaster, and (2) the students’ performances a year later.

Study 1. Students’ Performances at Graduation from MindBlaster: As of the Fall of 2002, over 60 students have graduated from MindBlaster. This research report is based on the first 39 graduates whose intelligences were measured with the Woodcock-Johnson Tests of Cognitive Abilities-Revised (WJR) and whose ADHD symptoms were measured with the Test of Variables of Attention (TOVA).

Summary of Findings: MindBlaster was found to improve intellectual functioning and reduce symptoms of ADHD in children and adolescents. The graduates’ intellectual abilities increased by an average of 27 percentile points from 55% to 82%. This moved the typical student from the middle of the average range to the high average range, an IQ gain from 102 to 114 on the WJRan 11-point IQ gain!

Significant improvements were also found in inattention and impulsivity for students having symptoms of ADHD, (i.e., those who placed in the lower quartile on the pre-test TOVA). Attention improved from the ADHD range to the Normal range (27 percentile points). Impulsivity also improved, going from the ADHD to the Borderline range (19 percentile points).

Conclusions: These findings offer support for the conclusion that MindBlaster can improve intellectual functioning and reduce symptoms of ADHD.

Study 2. Follow-Up Study: IQs ≥ One Year Post-Graduation: A study is ongoing of students who have been graduated from MindBlaster for approximately one year. At ≥ one year post-graduation, the students’ intelligences were retested and their parents were interviewed (see Parents' Comments). The current results are for eight students who were tested with the WJR.

Summary of Findings:

  1. From the pre-testing to post-testing at graduation from MindBlaster, these students averaged a gain of 13 IQ points (26 percentile points), which is very close to the average 12 point gain for all MindBlaster graduates.
  2. At post testing at graduation, the average IQ was 118, and at follow-up testing ≥ one year later, the average IQ was 116. This represents a decline of 2 IQ points or 3 percentile points.
  3. Compared with their IQs prior to beginning MindBlaster, the average student maintained an 11 IQ point gain ≥ one year later.

Conclusions: The students in this sample were typical of MindBlaster graduates in that they had averaged a 13 IQ point gain during the 10-week program. On average, they retained 85% of this 13 IQ point gain when retested ≥ one year after graduation. And most importantly, compared with their IQs prior to beginning MindBlaster, the average student maintained an 11 IQ point gain ≥ one year later.

These findings lend support to the conclusions that the MindBlaster cognitive training program significantly improves intellectual functioning and that these improvements last.

Study 3. MindBlaster after 12 years: In 2012 a study was conducted of 72 graduates of MindBlaster between 1999 and 2011. (Baxter, V., Kleemeier, R., and Kleemeier, C. 2/2012)* . The study found that MindBlaster yielded statistically significant gains in the areas of general intelligence, long-term memory and retrieval, visual processing, auditory processing, processing speed, and associative learning. The bottom line is that MindBlaster is a well-established, effective cognitive training program—it has stood the test of time.
Research is ongoing and these findings will be revised as additional information becomes available.
