Research
A Study on Dyslexic Students in Holland
Background
28 students (aged 13-17) were divided into three groups.
Group 1: 10 students diagnosed with dyslexia, receiving remedial education and auditory stimulation (Johansen IAS).
Group 2: 10 students diagnosed with dyslexia, receiving remedial education but without auditory stimulation.
Group 3: 8 non-dyslexic students.
The groups were matched on age, gender, I.Q., reading comprehension and mathematics/ calculation.
Significant differences were present between Groups 1 & 2 and Group 3 in technical reading (decoding) and spelling.
Methodology
Group 1 students listened to individually customised Johansen IAS CDs for 10 minutes per day, 5 days a week over a period of 15 to 18 months.
A battery of assessments was carried out on all three groups before and after Group 1 received auditory stimulation (Johansen IAS) and again on Group 1 10 months after completion of the programme. The skills tested included:
- Technical Reading (decoding)
- Reading comprehension
- Spelling
- Writing/ Copying
- Visual Memory
- Auditory Memory
- Phonemic Analysis
- Rapid Naming
- Pure-tone monaural and binaural listening audiometry
- Dichotic listening
Parent and Student questionnaires were also completed
Results
Immediately following Johansen IAS statistically significant improvements were seen in Group 1 compared to Group 2 and Group 3 students in:
- Technical Reading
- Spelling
- Phonemic Analysis
- Visual Memory
- Rapid Naming
- Audiometry
At follow-up 10 months later improvements were seen (some of which were statistically significant) in:
- Reading comprehension
- Writing/ copying
- Auditory Memory
Parent and student questionnaires reported improvements in attention and coordination.
Commentary
The results of this study support the belief that Johansen IAS can improve underlying skills which are often found to be weak in dyslexic students. Further studies with similar groups of students are ongoing.
We hope this study will be published in the not too distant future.
