Applied Quiz: Presentations And Everyday Traits

A second set of questions on this chapter, weighted toward applying the ideas rather than recalling them. Each one gives you a situation and asks you to name what is happening.

1. A boy does homework for forty minutes at the kitchen table and completes about twelve minutes of math. He says he was working the whole time; his father sees a half-empty worksheet and concludes he goofed off. Who is right?

  1. The father — output is the only honest measure of effort
  2. Both are reporting honestly; repeated captures plus the re-entry toll of rebuilding "where was I" consumed the hour
  3. The son, because homework at a kitchen table cannot be measured in output
  4. Neither, since forty minutes is too short a window to judge
Show Answer

The correct answer is B. This is the chapter's Omar example, and its point is that both people are reporting honestly from different sides of the same hour. The dishwasher clicks, a sister opens the fridge, someone else's phone buzzes — each capture costs a few seconds, but each return costs a working-memory rebuild, and those rebuilds eat the hour. That is why the fixes in Chapter 9 target the captures — headphones, phone in another room, cleared table — rather than demanding better recovery.

2. A mother's son was diagnosed combined-presentation at eight. At sixteen he sits calmly through dinner, so she wonders whether he is outgrowing it — while his grades collapse from missed assignments. What is the accurate reading?

  1. He is outgrowing it, and the grades are a separate problem
  2. The original diagnosis was probably wrong, since presentations do not change
  3. His presentation has shifted toward inattentive — the visible half faded and the invisible half is now running the show
  4. He should be re-diagnosed with a new condition to match the new picture
Show Answer

The correct answer is C. The DSM-5 deliberately renamed subtypes to presentations because longitudinal research showed the same person moving between pictures with age — typically a hyperactive-impulsive child becoming a combined teen and then an inattentive-looking adult. This is Nora's example: he hasn't grown out of anything. Families who know presentations shift keep watching the right things. Options A and B misread the shift, and option D treats a shifting presentation as a different condition.

3. A relative says: "She can't have ADHD — I've watched her focus on her art for four hours." What does this chapter say?

  1. Uneven-by-situation is exactly what the condition looks like; consistency is what would be surprising
  2. The relative has identified a genuine contradiction worth raising with the clinician
  3. Four hours of focus rules out the inattentive presentation specifically
  4. The observation is irrelevant, since hobbies do not involve attention
Show Answer

The correct answer is A. Situational variability is the signature of ADHD, not evidence against it. Interest, novelty, urgency, one-on-one attention, and immediate feedback all raise the reward system's pull and lower the load, so symptoms genuinely shrink in situations that supply them. The chapter puts the reply in the reader's hands directly. Option D is wrong — sustained artistic focus is very much attention, which is the whole point.

4. A parent tells a teenager: "You wrote a perfect essay last week, so I know you can do this." Why does this land badly?

  1. It reveals the parent has been monitoring grades too closely
  2. Praise of past work always reduces motivation
  3. Teenagers reject encouragement on principle
  4. It converts a best-ever performance into the new minimum standard, so encouragement lands as accusation
Show Answer

The correct answer is D. The chapter names this directly: the good day gets weaponized. Because regulation is inconsistent by nature — sleep, load, and interest move daily — a great day means conditions lined up, not that a new floor was set. The useful move is asking which conditions lined up, so they can be arranged on purpose, and the chapter notes that question is half of Chapter 9. Options B and C overgeneralize about praise and teenagers rather than naming the mechanism.

5. Someone needs to leave at 6:00 and starts getting ready at 5:52, sincerely believing showering, dressing, and finding shoes fits in eight minutes — the same belief as last time. What fix follows from the mechanism?

  1. Make time visible and external — clocks, timers, and an alarm at the start of getting ready rather than at departure
  2. Ask her to try harder to be realistic about time
  3. Set the departure time earlier without telling her
  4. Accept that lateness is fixed and plan around it permanently
Show Answer

The correct answer is A. Dana's eight-minute belief goes unrevised because the feel of duration never updates the way a visible clock would force it to. That is the shape of the fix, and Chapter 10 builds it. Option B asks the damaged faculty to repair itself. Option C is a workaround built on deception that leaves the mechanism untouched. Option D gives up on a problem the book treats as solvable with external structure.

6. A partner is deep in a project. Which approach to interrupting fits what the chapter says about hyperfocus?

  1. Interrupt immediately and firmly, since the absorption is a choice
  2. Never interrupt, since interruption always causes harm
  3. Use a negotiated protocol — a shoulder tap plus a five-minute warning, rather than a shouted demand from another room
  4. Wait silently until they emerge, however long it takes
Show Answer

The correct answer is C. Being yanked out of hyperfocus is genuinely jarring and often triggers a snap that reads as hostility, so the chapter recommends a negotiated protocol precisely to prevent a nightly fight. Note the framing: hyperfocus is the regulation coin's other face — the spotlight that resists steering toward dull tasks also resists steering away from gripping ones. Option A treats it as chosen. Options B and D make the household unworkable in the other direction.

7. In one week a woman forgets a dentist appointment made three weeks earlier, remembers her nephew's birthday on seeing a cake in a window, and forgets what her partner said while she was mid-email. Sorting this by "does she care?" produces noise. What sorts it cleanly?

  1. Sorting by how recently each commitment was made
  2. Sorting by cue availability — what was externalized, and what fired at the right moment
  3. Sorting by which people she is closest to
  4. Sorting by how much each item would cost if forgotten
Show Answer

The correct answer is B. Rosa's week is built to make this point: the dentist was time-based prospective memory with no reminder (the least reliable kind), the birthday was event-based and cued (it fired perfectly), and the partner's words were never encoded because working memory was full. Forgetfulness is selective by cue, not by importance — she loves the nephew and the partner equally, and the dentist mattered most. The chapter suggests doing this sorting together over a real week to end the "you'd remember if you cared" fight.

8. Twenty pleasant minutes of Legos end with "time for bath," and a meltdown follows. What actually triggered it?

  1. A dislike of bathing that has been building
  2. Deliberate testing of the parent's authority
  3. Overtiredness at the end of the day
  4. The unbudgeted gear-shift — surprise transitions cost the most, which is why warnings and countdowns pay the toll in advance
Show Answer

The correct answer is D. The chapter is explicit that the trigger wasn't bath, it was the transition. Cognitive flexibility's daily face is that transitions cost extra and surprise transitions cost most, so warnings, countdowns, and ritualized transitions work by paying that cost in advance. Options A and B read the meltdown as being about the bath or about defiance, which is exactly the misread the chapter is correcting.

9. A husband finally gets an unplanned Saturday. By 10 am his wife has reorganized a closet, proposed a day trip, and started two loads of laundry, visibly agitated by the calm he finds restorative. What is the accurate reading?

  1. She is rejecting rest, or rejecting him
  2. Unstructured stillness registers as under-arousal, and her system escapes the discomfort through motion
  3. She is avoiding a conversation she does not want to have
  4. She has not scheduled enough leisure activities to know how to relax
Show Answer

The correct answer is B. Restlessness in adults rarely looks like pacing — it looks like structural motion: overfilled calendars, side projects, difficulty with slow evenings. The chapter's advice is that couples who understand this negotiate rather than fight about whose Saturday is correct: restful-for-her can be a hike he joins, and restful-for-him gets protected windows she plans around. Option A is precisely the misread the example exists to correct.

10. Someone has had twelve browser tabs open for a week comparing toasters, and an RSVP has aged into rudeness. Which unlocks fit the mechanism?

  1. More research, so the correct choice becomes obvious
  2. Waiting for motivation to arrive naturally
  3. Structural moves — shrink the option set, set a decision deadline, or make the choice reversible
  4. Removing the deadline so the pressure eases
Show Answer

The correct answer is C. Decision paralysis happens because comparing options runs entirely in working memory while every option's downsides pull at attention, so the practical unlocks are structural rather than motivational: fewer options, a deadline, or "pick one; we can change it." Option A adds load to the exact system that is stalled. Option D removes the urgency that would eventually push the decision through.
