Lesson 6: Sleep DeprivationEXAM QUESTION
How can task performance be impaired by sleep
deprivation? (2 marks)
Saturday, 28 January 2012
Model Response:
Performance on complex, intellectual tasks is not impaired, whereas an individual’s ability to follow simple routines, as well as vigilance, attentiveness and mood, can be affected. Low level boring tasks are the most
likely to be affected, as deprivation may affect motivation rather than ability.

Sleep pattern shifts over the lifespan
~Most people your age get about 8 hours~Research shows that adolescents need 9 or 10 hours
~Many people report not being able to get to sleep quickly, not getting enough sleep and difficulty getting
up in the morning~Biological factors – rhythms – regulate when we sleep
and wake through the release of hormones that make us tired
~Our sleep-wake cycle is called a circadian rhythm – this means about a day

So why are you tired?During adolescence your sleep-wake cycle is shifted biologically (through the release of hormones) to make you require about 2
hours more sleep!But our school and work day does not really allow for this! (that’s
shit)As we consistently get less than optimum sleep we create a sleep
debt – this compounds like a fine you haven't payed – it gets bigger and bigger
As a result you try to catch up on the weekend! But then you go to bed later and compound the problem!
Research shows that less than 8 hours has a negative impact on cognitive function
