Which set matches the possible effects of short sleep on mood, memory and judgement described in the lesson?
- Less patience, weaker recall, poorer decision-making
- Less patience, stronger recall, more accurate decision-making
- More patience, weaker recall, more accurate decision-making
After a short night, you feel wide awake. What can you conclude?
- Your attention and judgement must be unaffected because you feel awake.
- Feeling awake alone cannot prove your thinking is unaffected.
- Your thinking must be impaired even without any signs of difficulty.
What should you remember about the length of sleep cycles?
- Sleep cycles vary in length across the night.
- Every cycle lasts exactly the same number of minutes.
- A whole night's sleep contains only one single cycle.
Which entry would be most useful in a week-long sleep log?
- Bedtime and wake time, without noting awakenings or next-day functioning
- Next-day mood and focus, without recording when or how long you slept
- Sleep and wake times, estimated sleep, next-day mood and focus
A student says, 'Only REM sleep helps learning and memory.' Which correction fits the lesson?
- Deep non-REM sleep supports memory, while REM sleep only affects mood.
- Both non-REM and REM sleep contribute to learning and memory.
- REM sleep supports memory, while non-REM sleep only restores the body.
If a hard conversation can safely wait, choosing a rested time may help you handle it.
Circle one: True False
Two students practise equally. One sleeps four hours before a test. Which explanation best connects that short night to a possible difficulty?
- Short sleep can make recall and concentration harder during the test.
- More waking time makes studied material easier to recall because there is less time to forget it.
- Equal practice protects test concentration, so sleep length should affect only physical energy.
After several short nights, a student has one better night and feels more alert. What can they reasonably conclude?
- All effects of the short nights have now disappeared completely.
- The better night could not have helped attention or mood at all.
- It may have helped, but full recovery is not proved.

Sleep and next-day judgement W1-mt_YvDXYIiyAb-s1

Less patience, weaker recall, poorer decision-making · Short sleep can make it harder to stay patient, recall information and weigh choices. The lesson does not describe improved recall or judgement as benefits of short sleep.
Feeling awake alone cannot prove your thinking is unaffected. · Feeling awake alone proves neither that thinking is unaffected nor that impairment is certain. Short sleep can affect attention and judgement.
Sleep cycles vary in length across the night. · Sleep stages repeat in cycles, but a cycle is not a fixed-length timer.
Sleep and wake times, estimated sleep, next-day mood and focus · To compare sleep with next-day functioning, record both. Estimates of actual sleep add information that bedtime and wake time alone can miss.
Both non-REM and REM sleep contribute to learning and memory. · Both non-REM and REM sleep contribute to learning and memory. Assigning memory to just one phase leaves out a contribution taught in the lesson.
True · Rest can support patience and attention. It does not guarantee agreement, and urgent safety action should not wait.
Short sleep can make recall and concentration harder during the test. · Practice matters, but sleep also supports recall and attention. Equal practice does not rule out a possible effect of short sleep during the test.
It may have helped, but full recovery is not proved. · One better night can help. Feeling more alert does not establish that every effect of repeated short sleep has gone.
