Um it's in one of the green boxes.

Grivas is the best book...

[Darren]

Apparently oxford is better with the new topics

[Slumdawg]

Just be thankful none of you have to deal with heinemann. It's actually sickening to see the amount of stuff they leave out and the amount of junk they put in.

An adolescents sleep cycle is relatively different to that of other periods due to the fact many suffer from Delayed sleep phase shift syndrome, which is the inability to reset the sleep/wake shift cycle to match external time cues. Therefore adolescents biological timing system (known as the circadian rhythm) is disrupted to the point where their peak awakeness and alertness is shifted forwards. The reason for adolescents being susceptible to DSPSS is owed to the demanding lifestyles they lead which requires them to wake and sleep at strict times. (Such as school, work etc.)
Ultimately adolescents body clock is shifted forward one or two hours, making it difficult to sleep at normal times and wake at normal times. Research also suggests melatonin (sleep hormone) is secreted at unusual times for adolescents.

Unsure about the second question, that would come in handy though to add to my notes.

Sleep recovery patterns.. I would probably answer it by stating we usually sleep additional hours over each day to gradually compensate for loss sleep. REM rebound would cause more REM during sleep, loss of NREM sleep would see more slow wave sleep. (3/4 Delta waves)

[iNerd]

Interesting first answer - we have to actually know DSPS? That was in a green box - I ignored it!

Yes, 2nd Q needs answering!

After how many days are the effects of sleep deprivation likely to be evident?

For third one be careful. We don't have to FULLY compensate for lost hours of sleep. I was more unsure of whether 'microsleeps' will count as 'sleep recovery' patterns. REM Rebound sounds correct.

Exactly... we don't fully compensate for lost hours of sleep, thats why we are prone to gradually build up compensation rather than sleeping all at once to instantly rectify it. Say you slept for 4 hours in one night; the next night you'd be more prone to sleeping for longer than the stock-standard 8 hours, probably 10 or so. It's not exact but it's relative.

Ah what I meant was if you lost 8 hours sleep you don't have to catch up on all 8. So using your example you would sleep 12 instead of 8 hours to catch up however you're still missing 4 but that's okay!

(all hypothetical) figures!

EDIT: I just realised that by my figures you suffered total sleep deprivation the first day (missed out on 8hours) and the next day you'd spend 12 to recover BUT THE THIRD DAY you don't need to spend 8+4 (12) but back to your normal 8...

[burbs]

I think its 3-4 days

[Darren]

@atar, wtf? lol

[iNerd]

@atar, wtf? lol

Mhmm yeah...it makes sense in a weird, twisted way.

Basically you don't have to catch up on all lost hours but you sleep longer the next night and than return to normal.

I'd say the effects of sleep deprivation are evident after one nights sleep deprivation considering a person who hasn't slept is already more irritable, lethargic, tired, etc. than someone who has slept. So I'd say 1 night sleep deprivation is enough to show some effects already (although they are usually quite minor), the more serious effects tend to occur after 3-4 nights without sleep.

I'd agree with this too.

17 year olds need 9 to 10 hours sleep?! Damnn no wonder I've been really tired lately LOL

Yep - most folk our age are actually chronically fatigued - with disastrous results in many areas such as road safety.

Do you guys have to learn about the biological side of why adolescents tend to sleep later? Basically it results in the poorer regulation of melatonin (a hormone involved in the regulation of sleep), which is released later in the night in adolescents.

Actually, Dr Karl has written about it here: http://www.abc.net.au/science/articles/2007/05/03/1913123.htm

[iNerd]

Yes we learn about the biological aspect - interesting article!

My main concern was with the 'include research to support these theories'.

[a/b]

Has anyone had a media analysis SAC? Mine is on States of Consciousness and Sleep. Do I need to know anything on Research methods and how should I go about studying for it?

Thanks guys
