This physical format of bound pages revolutionized reading by making text stable and easy to navigate.
What is the codex
These clickable elements interrupt linear reading and encourage jumping between ideas.
What are hyperlinks?
Digital reading often leads to lower levels of this — the ability to remember what was read.
What is retention?
This short‑form video platform is a modern example of Carr’s argument about shrinking attention spans.
What is TikTok?
Carr argues that this determines how we think — not just what we read.
What is the medium?
Carr argues that this type of reading — slow, focused, and reflective — was shaped by the book.
What is deep reading?
Carr argues that this common digital behavior — switching between tasks — weakens deep focus.
What is multitasking?
The internet encourages this fast, fragmented style of thinking that contrasts with deep reading.
What is rapid, scattered thinking?
Students often have 10–20 of these open, creating constant cognitive switching.
What are tabs?
Books encourage this slow, immersive cognitive state that digital media disrupts.
What is deep focus?
Before books, this older format made deep reading harder because it required continuous unrolling.
What is the scroll?
Online reading increases this type of mental effort because the brain must constantly decide what to click.
What is cognitive load?
Carr compares today’s digital shift to this historical invention that once reshaped human thought.
What is the printing press?
These audio formats differ: one mimics deep reading, the other mimics conversational skimming.
What are audiobooks and podcasts?
Digital media encourages this type of thinking, which prioritizes speed over depth.
What is fast processing?
The stability of printed pages helped readers build these mental structures that support comprehension.
What are mental models?
This reading pattern, common online, involves quickly scanning text instead of absorbing it.
What is skimming?
This neurological concept explains how repeated behaviors — like skimming — reshape the brain.
What is neuroplasticity?
These AI tools provide summaries that reduce the need for long‑form reading.
What are AI summary generators?
Carr says the internet trains us to expect constant stimulation, weakening this mental ability.
What is patience?
Carr says the book trained the brain to follow long, complex arguments, which strengthened this cognitive skill.
What is sustained attention?
Carr says digital environments push us toward this shallow form of processing information.
What is surface‑level processing?
Carr argues that digital media weakens this ability to stay with a single idea for an extended period.
What is sustained concentration?
This modern habit — checking your phone every few minutes — mirrors the fragmented attention Carr warns about.
What is micro‑checking?
This is the central idea of Chapter 6: the physical form of a medium shapes the way the brain processes information. Answer: What is media determinism?
