The idea of BLT is that you administer the light when the individual would usually be asleep, shifting their sleep-wake cycle.
Your first example refers to DELAYED circadian rhythm phase disorder (such as with adolescence). Administer BLT at around 6am or in the morning when the individual would usually be asleep, allowing them to stay awake during that time and shifting their sleep-wake cycle FORWARD to the desirable time.

Second example is ADVANCED circadian rhythm phase disorder (shift work/jet lag when travelling west/elderly sleep patterns). Administer BLT at 6pm, when the individual is close to going asleep. This allows them to continue to stay awake when they would usually be asleep, shifting their sleep-wake cycle BACKWARDS to the time they should be going to sleep.

This helped a lot! Thank you!

Yes. Remember that alcohol is a depressant, and that a meditative state can be considered an ASC

Do altered states of consciousness mostly show theta brain waves?

Nah, but having theta waves suggests that the person MAY be in an ASC
Eg rem sleep is an ASC but has beta-like waves

I hope the 10-marker is on neurons, memory or something like that and NOT sleep :/

If you prepare for the worst you'll be able to cope with anything that happens :)
Might want to quickly brush up your understand as doubtless there'll be questions about sleep somewhere

Do we have to know about the role of the suprachiasmatic nucleus and 'zeitgebers' in sleep or is that too much information and not needed?

Yes definitely the suprachiasmatic nucleus (about how it detects incoming light and sends the information to the pineal gland where a decision is made about how much melatonin is to be released.
I'm not too sure about zeitgebers however the concept is not too difficult and they can just be described as environmental time cues.

I would assume yes since it is involved in the resistance stage of the GAS model as well as important in the way cortisol is secreted.

Is the freeze response due to activation of the sympathetic nervous system or the parasympathetic nervous system?

Psych VCAA 2015 exam question 10c??
Students could gain one mark for identifying punishment (or negative punishment) as the learning
principle. Positive punishment was not an acceptable response (this relates to application of an
negative stimulus, rather than taking away a desired stimulus). The act of taking away a desired
activity/positive reinforcer as a consequence for an undesirable behaviour (i.e. not completing
homework) is what makes this punishment, rather than negative reinforcement. Students could
then gain another mark if they explained how punishing the undesirable behaviour (i.e. not doing
homework) might be effective in producing the desired response. This aspect of the question
focused on motivating a desired response. The best response to this aspect of the question was to
indicate that punishment of the undesirable behaviour may motivate Najida to do her homework so
as to avoid this punishment.

Is the answer produced by vcaa contradicting?? Can't tell whether it's saying negative reinforcement or punishment is the answer? Can someone explain please? THANK YOU!!

Yes, but don't worry! All you need to know is that during stress, the hypothalamus stimulates the pituitary gland to release ACTH (a hormone) which travels through the blood stream, stimulating the adrenal gland to release cortisol. This response takes a few minutes to occur, but is very long lasting.
