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
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%
82%. This moved the typical student from the middle of the
average range to the high average range, an IQ gain from
to 114 on the WJR—an 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). Click

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:
- 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.
- 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.
- 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.
