We invite you to participate in a research to investigate the capability of using EEG (Electroencephalogram) for Dyslexia Detection. This study is part of my PhD in Information Technology, supervised by Dr. Mohd Fairuz Shiratuddin and Associate Prof. Dr. Kevin Wong at Murdoch University.
Nature and Purpose of the Study
The common practice of dyslexia detection is based on behavioural aspects such as reading, writing and IQ skills, which are external symptoms.
The aim of this study is to investigate how EEG can be used to detect dyslexia by looking into internal symptoms through brain wave patterns. The final outcome will be a framework for analysis and classification between dyslexics and non-dyslexics through a computer analysis of EEG.
If you consent to take part in this research, it is important that you understand the purpose of the study and the tasks you will be asked to complete. Please make sure that you ask any questions you may have, and that all your questions have been answered to your satisfaction before you agree to participate.
What the Study will Involve
Inclusion and Exclusion Criteria
The research will not recruit any participants who have any medical history relating to epilepsy and other seizure disorders as an extra precaution.
This is because EEG may cause a seizure for people with epilepsy and other seizure disorders, for the stimuli presented during the test, such as a flashing light. This is caused by the stimuli and not by the EEG. Although this research does not involve having to present such stimuli as an extra precaution, it will exclude participants falling to this category.
- 18 years and over.
Since the handedness has an effect on the EEG activities between the right-handed and left-handed subjects (Andrew Ng & Leong, 2014; Provins & Cunliffe, 1972), this research will be using only right-handed subject to keep the data consistent
- Have normal or corrected to normal vision or hearing.
Fluent in English reading and writing – English is your first language or studied in English medium for over 5 years.
The research includes having to perform reading and writing related tasks in English.
Test Group (Dyslexics)
- Diagnosed as dyslexic by a psychologist
Control Group (Non-dyslexics)
- Healthy individuals free from motor or neurological conditions such as Dyslexia, ADHD (Attention Deficit Hyperactivity Disorder), and Autism etc.
If you decide to participate in this research, you will be asked to complete the following tasks while the EEG recordings are being captured. It is estimated that the tasks will take approximately 45 to 60 minutes.
What is the device involved?
EEG is a test that detects electrical activity in your brain using small, flat metal discs (electrodes) attached to your scalp. It is a completely non-invasive and non-hazardous imaging technique that allows us to measure the tiny electrical currents produced by the brain during a certain task. It is a very safe test; it records signals coming from the brain and at no time is any electrical current put into the brain or body.
What are the tasks asked to complete?
- Relaxed state
- Reading related tasks – words and nonsense words
- Writing related tasks – writing, typing and copying words
- Rapid Automized Naming – Naming familiar things such as letter, digits, objects and colours quickly
- Browsing the web
- Interpreting tables or graphs or charts
- Look at a number and key it on to the phone to make a call
Voluntary Participation and Withdrawal from the Research
Your participation in this research is entirely voluntary. You may withdraw at any time without discrimination or prejudice. All information is treated as confidential and no names or other details that might identify you will be used in any publication arising from the research. If you withdraw, all information you have provided will be destroyed.
Benefits of the Research
It is possible that there may be no direct benefit to you from participation in this research. While there is no guarantee that you will personally benefit, the knowledge gained from your participation may help to introduce an improved framework for analysis and classification between dyslexics and non-dyslexics through a computer analysis of Electroencephalogram (EEG), thus complementing the current dyslexia detection techniques.
If you have any questions about this project please feel free to contact either myself, Harshani Perera on H.Perera@murdoch.edu.au or my supervisor, Dr. Mohd Fairuz Shiratuddin, F.Shiratuddin@murdoch.edu.au .My supervisor and I are happy to discuss with you any concerns you may have about this research.
Once we have analysed the information and completed the research, we will put a summary of our findings on our website.
If you are willing to consent to participation in this research, please read the Consent Form.
