Something of interest- studies have found that young children who can easily repeat back made-up words are likely to acquire a good vocabulary. Researchers have also found that non-word repetition at age four is a good predictor of vocabulary and reading skills at age five. Difficulty in repeating non-words might indicate future problems with regard to learning foreign languages and acquiring vocabulary.
Simple test for slightly older children– Ask your child to repeat back each of the listed non words immediately after you say it. Good scores by age group match the scores of relatively high achieving children of high socioeconomic status from Cambridge, England.
