Hey everyone,
I'm the writer of the Connect Ed psych solutions, I thought I'd leave a comment regarding a few queries I've been getting from various students to help put people's minds at ease!
There seems to be a lot of debate around Question 6 of Section A, in response to this, I decided to email one of my psychology lecturers who is a leading sleep researcher. He has conducted a number of sleep deprivation studies, so I think his opinion is very valuable.
His response:
"In the context of the question you sent, the answer would be C, given that the people could go back to sleep straight away and they were only woken every hour. It wouldn’t particularly affect REM given that the REM – NREM cycle is about 90minutes. Indeed I’d suggest that you might not even see any effects even after seven nights of this, but for their purposes it would be C."
It'll be interesting to see what VCAA allows, there's still a slight chance option D might be correct, although I still personally believe option C is the one they'll accept.
Also, for question 3b if you discussed EEG that is also acceptable IMO, however, this technique is slightly more difficult to discuss in regards to the case study, which is why I didn't include them in the solutions. Although if you've justified them properly you'll be fine.
Hope everyone gained something from looking at the solutions and I hope to see you all at the Unit 4 lecture so you can smash the end of year exam too!
