Psychologists! What's your diagnosis?

What did everyone think about the stage 4 sleep question?

[KeyMan]

The two characteristics I wrote were:

Very difficult to wake someone up in that stage.
If woken up, the person will experience post-awakening lag called sleep inertia.

[melaniej]

Yeah I said Parasympathetic as well. And the associated changes could have been things such as return heart rate to normal, etc etc

And as for stage 4 sleep...
well obviously low freq high amp

and the 2 characteristics
deepest sleep, hard to wake up from!
and i said that it occurs towards the beginning of sleep, not at the end of it

[cathtacular]

i said it slants down to figure b (on the left) because... shit, you were right. damn it! arghhhhhhhh

Thanks mel. I had the same as you.

[sonnypls]

meh i wrote, sleep walking and sleep talking can occur during this stage.

You could also say that periods of stage 3/4 sleep reduce as the night goes on, leading to greater time spent in REM.

[moshi]

phew i was stressing about the parasympathetic one...i said the RR rate would fall due to bronchi contracting in the lungs, and that HR would also fall
sleep - i said sleep phenomena can occur in that stage, and that it occurs less often as the night progresses

[cathtacular]

i wrote

hard to wake up
and sleep phenomenon can occur, is that not right?

[thelovecatsx]

What did everyone think about the stage 4 sleep question?

i put sleep phenomenon occurs and it's the deepest sleep, therefore being hardest to wake up from.
i'm thinking sleep phenomenon may have not been right. 

[Nick]

Yeah that's fine. It would have been best to specify though- sleep talking, walking and night terrors.

[Hughie]

did anyone find it long?

Damn i wrote that then put a line through my answer and changed it to Delta waves being dominant and sleep pehnomena,

Do you think they would consider my crossed out answer?

[moshi]

they don't always occur, but they can...so hopefully our answer was correct
what about the variables in the case study question? i said the results would be difficult to generalise to the wider population, but that was a guess and i'm not quite sure

I doubt it, but you've probably already provided enough to attain the marks anyway.
