Can You Do Two Things at Once?

People say they multitask. Mostly they do not. The brain can run two tasks together only if at least one is automatic. Walking and talking works because walking is automatic for an adult. Reading and listening to speech does not, because both need the same language system. What feels like multitasking is usually rapid switching. Each switch costs time — a fraction of a second to disengage and re-engage — and the costs add up. In experiments, people doing two tasks alternately take substantially longer in total than doing them one after the other, and make more errors. They also do not notice. Switching feels efficient because you are busy the whole time. The practical conclusion is unpopular but consistent: for anything demanding, doing one thing at a time is faster.

  1. 1. Why does reading while listening to speech not work?
  2. 2. What does "disengage" mean?
  3. 3. What does "automatic" mean here?
  4. 4. What does each switch cost?

What Sleep Is For

Sleep is not switching off. Parts of the brain are busier asleep than awake. Two claims are well supported. The first is that sleep consolidates memory: during deep sleep, the day's experiences are replayed and moved from short-term storage into long-term. Interrupt deep sleep and recall of the previous day drops measurably. The second is that sleep clears waste. The spaces between brain cells widen during sleep, and fluid washes through, removing proteins that build up while awake. A third claim — that a particular number of hours suits everybody — is not supported. Need varies with age and between individuals, and self-reported sleep is unreliable. Teenagers are a special case. Their body clocks genuinely shift later at puberty, which is a biological fact rather than a preference, and school start times mostly ignore it.

  1. 1. What happens to recall when deep sleep is interrupted?
  2. 2. What does "self-reported" mean, and why does the author mention it?
  3. 3. What shifts in teenagers at puberty?
  4. 4. What happens to the spaces between brain cells during sleep?

Answer key — Self-Correct in a Dense Text

Set 23. Prints on its own sheet.

  1. 1.1. Both need the same language system. 2. To disengage is to stop attending to a task, which costs a fraction of a second at every switch. 3. Done without conscious attention, like walking for an adult. 4. A fraction of a second to disengage and re-engage.
  2. 2.1. It drops measurably. 2. Given by people about themselves — the author mentions it because it makes sleep data unreliable. 3. Their body clocks shift later. 4. They widen, and fluid washes through.
