Dyslexic children often experience difficulty with phonetic decoding. Researchers and educators use nonsense words – also called nonwords or psuedowords – as a tool to assess phonetic decoding ability.
These meaningless words are sequences of letters that follow simple and pronounced but unimportant phonetic rules – like bif or yom or mig. You can also hop over to this website to know more about nonsense words.
Many schools also have tools to measure early reading skills, which includes a test to decipher nonsense. It makes sense to include gibberish for evaluation purposes. There are many tutors available in Charlotte that also provide the facility of decoding nonsense word assessment test.
At least in theory, this can help determine whether a child's reading difficulties are due to phonetic coding difficulties or other causes such as visual or superficial dyslexia.
Since this is a skill that children are now testing, it has become a skill that is increasingly being taught directly.
The point of testing a child's ability to decipher nonsense is to assess their ability to quickly decipher an unfamiliar letter sequence. However, if children were previously exposed to the same letter pattern through worksheets or training, it cannot be determined whether the child's performance on the test was due to phonetic skills or memorization.
