Researchers at Sussex University have found that repetition is more likely to help them improve their reading skills. "What we think is happening with reading is that each time a child hears the book, they are picking up new information," said psychologist Dr Jessica Horst, who conducted the research. She added: "We know that children who watch the same television programme over and over again do better in comprehension tests afterwards." The researchers devised an experiment with three-year-olds in which they were exposed to two new words to test the theory.
