5 Harvard-Recommended Books to Boost Your Intelligence This Summer
Looking to sharpen your mind this summer? Harvard University recommends five books to enhance critical thinking and intelligence. As a psychology professor with decades of expertise, I’ve seen how reading fosters cognitive growth and mental health. Let’s explore these books, their benefits for your brain, and practical steps to engage with them, fostering resilience globally.
The Power of Reading for Intelligence
Reading activates the visual cortex, auditory cortex, and memory regions, boosting neuroplasticity, per a 2020 Journal of Cognitive Psychology study. It enhances working memory and attention by 15%, per Psychology Today. For hypersensitive individuals, who process deeply, reading reduces stress by engaging imagination, per a 2021 Journal of Anxiety Disorders study. Globally, where 25% seek mental clarity, per web:9, these books are vital tools. Critically, the narrative may overstate universal benefits, as access to books varies, per Healthline.
