Children who read for pleasure at the age of 10 have far higher vocabulary scores by the age of 42.

Researchers at the Institute of Education(IOE)have found that the most crazy childhood readers score far higher on vocabulary tests 30 years later.The new study suggests that children who read for pleasure carry the intellectual(智力的)benefits with them far into adulthood.

“The long-term influence of reading for pleasure on vocabulary that we have identified may be because the frequent childhood readers continued to read throughout their twenties and thirties,”says lead author Professor Alice Sullivan at the IOE.Researchers followed 9,400 British people from the age of 10 up to 42.Their vocabulary was tested using a simple quiz which asked participants to match up words to the most similar meaning.

Those who had regularly read for pleasure at 10 scored 67 percent at the age of 42,while infrequent childhood readers scored only 51 percent.

The IOE study also found that what people chose to read as adults mattered as much as how often they read.The greatest improvements between ages 16 and 42 were made by readers of ‘elegant’ fictions such as Booker Prize winning novels.And they found that readers of quality newspapers,including online versions,made more progress in vocabulary throughout their lives than those who read tabloids.

In addition,generally speaking,the adult readers who especially read broadsheets(宽幅印刷品)scored 76 percent on the assessment compared to 57 percent amongst those who didn’t.
