The works of Shakespeare and Wordsworth are “rocket-boosters” to the brain and better therapy than self-help books, researchers will say this week.

Scientists, psychologists and English academics at Liverpool University have found that reading the works of the Bard and other classical writers has a beneficial effect on the mind, catches the reader’s attention and cause moments of self-reflection.

Using scanners, they monitored the brain activity of volunteers as they read works by William Shakespeare, William Wordsworth, T.S Eliot and others.

They then “translated” the texts into more “straightforward”, modern language and again monitored the readers’ brains as they read the words.

Scans showed that the more “challenging” prose (散文)and poetry set off far more electrical activity in the brain than the more pedestrian versions.

Scientists were able to study the brain activity as it responded to each word and record how it “lit up” as the readers encountered unusual words, surprising phrases or difficult sentence structure.

This “lighting up” of the mind lasts longer than the initial electrical spark, shifting the brain to a higher gear, encouraging further reading.

The research also found that reading poetry, in particular, increases activity in the right hemisphere (半球)of the brain, an area concerned with “autobiographical memory”, helping the reader to reflect on and reappraise their own experiences in light of what they have read. The academics said this meant the classics were more useful than self-help books.

Philip Davis, an English professor who has worked on the study with the university’s magnetic resonance centre, will tell a conference this week: “Serious literature acts like a rocket-booster to the brain.

"The research shows the power of literature to shift mental pathways, to create new thoughts, shapes and connections in the young and the elderly alike.”
