Is it possible to read too much and lose touch with reality? This is a question I often ponder. In 2020, I devoured nearly 100 books, which led me to explore some of the most intriguing studies on reading. The findings are compelling and suggest that, if people were aware of these insights, they would prioritize reading as a daily habit, much like brushing their teeth or hitting the gym.
Section 1.1: Enhancing Brain Connectivity through Fiction
One fascinating study conducted at Emory University in Atlanta examined how reading novels impacts brain connectivity. The research involved 21 participants—12 women and 9 men aged 19 to 27—who underwent functional magnetic resonance imaging (fMRI) scans over 19 consecutive days while reading the novel Pompeii: A Novel by Robert Harris.
The results revealed that as the story progressed, participants' arousal levels increased, peaking at the climax. Notably, three distinct cortical networks showed enhanced connectivity during the reading process. This indicates that reading not only fortifies language processing areas but also engages sensorimotor regions linked to semantics. Remarkably, brain activity persisted the following day, akin to muscle memory, particularly in the left temporal cortex associated with language.
In essence, reading novels boosts your brain's connectivity, improving your ability to process and comprehend information. This suggests that avid readers might relate better to others and navigate the world more effectively.
Section 1.2: Reading as a Shield Against Dementia
A comprehensive study led by Drs. ATC Lee, Richards, Chan, and Lam explored the correlation between intellectual activities in adulthood and dementia risk. This extensive analysis included 15,582 adults over an average of five years, revealing that 1,349 participants (8.7%) developed dementia.
The findings indicated that individuals at higher risk typically had lower educational levels and pre-existing health issues like hypertension and depression. Those who engaged in intellectual activities, such as reading, exhibited a reduced risk of dementia compared to less active individuals. The study underscores the significance of intellectual engagement in older age as a potential safeguard against dementia.
Chapter 2: The Cognitive Stimulus of Classic Literature
The first video, Reading Fiction Changes Your Brain, let me explain, elaborates on how fiction reading alters brain function and enhances connectivity.
In the second video, What Reading Does To Your Brain, viewers gain insight into the cognitive impacts of reading.
Section 2.1: The Impact of Shakespeare on Brain Activity
Research at the University of Liverpool demonstrated that engaging with Shakespeare's language can stimulate positive brain activity. Professor Davis and his colleagues monitored 20 participants using electroencephalograms while they read excerpts from Shakespeare's plays.
Shakespeare's unique style, characterized by functional shifts—using nouns as verbs—requires readers to decipher meanings contextually, thereby forging new connections between words and phrases. This process incites a spike in brain activity, akin to solving a puzzle. As Professor Davis noted, the unexpected nature of Shakespeare's language excites the brain, creating a sense of drama from simplicity.
Section 2.2: Jane Austen and Cognitive Function
A team at Stanford University investigated the interplay between reading, attention, and distraction by having participants read Jane Austen novels while inside an MRI machine. Participants navigated the text as if browsing in a bookstore, pausing to read sections more thoroughly.
The findings were enlightening: increased blood flow was observed in various brain regions, suggesting that engagement with literary texts demands coordination of complex cognitive functions. This implies that reading literature can serve as a valuable exercise for enhancing cognitive abilities and potentially treating concentration issues.
