Book excerpt: A cognitive psychologist explores how smartphones, pop-up ads, and other distractions are impacting our attention spans—and what we can do to improve concentration. We are in the midst of an attention crisis—caused in large part by our smartphones. The a constant stream of information is making it harder and hard to concentrate. In this book, attention expert and cognitive psychologist Stefan Van der Stigchel explains how concentration works and offers advice on how to stay focused in a world of beeping smartphones, channel surfing, live-tweeting, pop-up ads, and other distractions. The good news is that we now know more about brain and behavior than ever before, and Van der Stigchel draws on the latest scientific findings to explain: • How the battle for our attention began long before the digital era • Why our phones are so addictive • The importance of working memory and how to increase its capacity • Why multitasking is bad for our concentration—as seen in the Best Picture debacle at the 2017 Oscars • The positive effects of taking “tech breaks”, meditation, and daydreaming • And much more! We can win the battle for our attention, Van der Stigchel argues, if we have the knowledge and the tools to do it.
