So from my understanding REM sleep in adolescence is about 20% of sleep, and it comprises 15-20% of sleep for the elderly, so what would you say for adults? Just under 20%?

proportion of REM sleep is pretty stable from adolescence onwards, leveling off at about 20%, so yeah, just a little bit under 20% should be fine :)

Q: Can we be examined on Korsakoff's?

And also, I'm not sure why D is the answer, I thought it was C...

Dr Jackson is conducting an experiment investigating the effects sleep deprivation has on our ability to
remember a list of ten nonsense syllables. He has conducted three similar experiments, each time using
the same group of participants. Which ethical principle is he not adhering to?
A. Integrity
B. Respect for persons
C. Beneficence
D. Justice

The answers say: The correct answer is D. Justice requires that researchers should ensure that there is a fair distribution of benefits and burdens within a population of research interest, as well as for any individual participant. Dr Jackson is not adhering to this ethical principle as he is using the same group of participants for each experiment, therefore unfairly burdening a specific group of people within a population.

I thought "a fair distribution of benefits and burdens" is Benefience?
Can someone please explain the difference?

Yes, Korsakoff's has a chance of appearing on the exam.

Beneficence is involved in whether the potential benefits of the research justify any risk, what risks of harm could arise in the proposed research, and informed consent.
Justice, however, discusses what is the justification for selecting a person or group of people as participants over other people, and whether they are representative of other people intended to benefit from the research. There isn't really any justification for using the same group in each experiment.

I came across this question on a trial exam:

In 1932 British psychologist Frederick Bartlett believed that Ebbinghaus studied memory in
an artificial way. Explain what Bartlett meant by this, and state how his research overcame the
weakness he saw in Ebbinghaus' work.
(2 marks)

Could we be examined on Bartlett?

I doubt it would be a major part of the exam, but  I think it's not impossible that it could appear somewhere. No harm reading up on it before tomorrow I guess.

This was how the question was answered..Might help you get a brief idea on what he did

Bartlett believed that by using nonsense syllables, Ebbinghaus ignored important variables
such as the influence of prior experience, which play a part in everyday human memory.
(1 mark) Bartlett had participants read a story/essay or look at a picture. They would then be
asked to recall/describe the passage/picture (1 mark).

Does sleep deprivation affect simple or complex tasks?! I'm having a mental blank. I'm pretty sure it's simple tasks but can anyone clarify?

Yes, it is only simple tasks. As in a difficulty doing them while complex tasks are relatively unaffected.
