Study: Edublox Improves Processing Speed of ADHD and Dyslexic Students

Processing-Speed

Some kids are naturally fast.  They run, talk, complete homework assignments and do all sorts of things at a rate that seems appropriate for their age. Other kids don’t, or, perhaps it would be fairer to say they can’t. These are kids who may have what are known as processing speed deficits. 

Processing speed involves one or more of the following functions: the amount of time it takes to perceive information, process information and/or formulate or enact a response. Another way to define processing speed is to say that it’s the time required to perform an intellectual task or the amount of work that can be completed within a certain period of time. Even more simply, processing speed could be defined as how long it takes to get stuff done.

There are three main components of processing speed:

  • visual processing: how quickly a student’s eyes perceive information and relay it to the brain (such as reading directions or noticing a teacher’s hand gestures)
  • auditory processing: how quickly a student hears a stimulus and reacts to it (such as following oral instructions or participating in a discussion)
  • motor speed: how strong a student’s fine motor agility is, leading to academic fluency (such as filling out timed math worksheets)
    .

Processing speed is one of the main elements of the cognitive process, which is why it is one of the most important skills in learning, academic performance, intellectual development, reasoning, and experience.

Slow processing speed and learning disabilities

Slow processing speed is not a formal learning disability, but it can play a part in learning and attention issues like dyslexia, ADHD, dysgraphia, dyscalculia, and auditory processing disorder.

When a student has slow processing speed, certain academic tasks can take them longer than the average student. According to the authors of Bright Kids Who Can’t Keep Up, “processing speed does interact with other areas of cognitive functioning by negatively impacting the ability to quickly come up with an answer, retrieve information from long-term memory, and remember what you’re supposed to be doing at a given time” (Braaten and Willoughby, 2014, p.4).

Evidence suggests that processing speed problems are a major underlying factor in both reading disability and ADHD, as the two disorders often go hand in hand (Shanahan et al., 2006). Studies also suggest the slow reading and slow motor responses often seen in those with dyslexia may be related to poorer processing speed (Stoodley and Stein, 2006).

Improving processing speed

The key to improving processing speed lies in making stronger connections in the brain, which allow brain signals to travel at higher speeds. To investigate the effectiveness of Edublox in improving processing speed, educational specialist Dr. Lee DeLorge in Ohio put the program to the test. Sixty-seven students aged 5 to 18 with ADHD, dyslexia, dyscalculia and non-specific learning disabilities participated in her study. Ninety-four percent of the learners improved significantly. Results were as follows:
.

  • Thirty-five students with ADHD showed a combined increase of 52.45 percent, from a pre-test average of 37.24 percent to a post-test average of 89.69 percent.
  • Thirteen dyslexic students showed a combined increase of 46.76 percent, from a pre-test average of 41.31 percent to a post-test average of 88.07 percent.
  • Two students were diagnosed with dyscalculia and showed a combined increase of 57.38 percent, from a pre-test average of 39.76 percent to a post-test average of 97.14 percent.
  • The remaining learners were non-specific learning-disabled and showed a combined increase of 64.14 percent, from a pre-test average of 30.40 percent to a post-test average of 94.54 percent.

Interview

In an interview that was broadcast in February 2011 on WKYC, a television station located in Cleveland, Ohio, Dr. DeLorge explained what cognitive skills are and how Edublox methodology strengthens a child’s cognitive skills.
