How can I remember what type of brain waves are in each sleep stage?

BAT'D

Awake- beta.
NREM 1- alpha.
NREM 2- theta.
NREM 3-theta and delta.
NREM 4-delta (has to be 50% to be stage 4)
 
And then REM is beta like waves. Hope that helps.

Can a conclusion be drawn and the hypothesis supported if the results were statistically significant, although a convenience sampling was used which was not representative of the population?

A conclusion consists of either supporting or rejecting a hypothesis- so basically you can always draw a conclusion. If the results are significant, you can say that there's evidence that the hypothesis is supported, BUT, you cannot generalise the results to the population as you've used a convenience sample. My teacher says that when you use a convenience sample, say that the results can't be generalised but also say; if the researcher could generalise, then...

Could someone please give me a simple explanation on how and why the HPA axis is activated? Thank you xx :-*

I also need some strengths and limitations of Lazarus and Folkman's transactional model of stress and coping! xxxx

The HPA axis is activated when there is a prolonged stress response (e.g stress experienced in the lead up to exams).
The presentation of a stressor stimulates the hypothalamus to release a hormone that in turn stimulates the pituitary gland. The pituitary gland releases a hormone called ACTH which travels through the bloodstream to the adrenal cortex. The adrenal cortex then releases the stress hormone cortisol which is involved in energising the body and causing heightened arousal. Prolonged release of cortisol causes an immunodeficiency thus causes a person to become ill. That's kind of why people get sick physically when they're stressed.  Hope that helps.

Strengths:


-Unlike the fight/flight and HPA axis, this model uses a cognitive approach to explain stress especially one that we can have control over.
-Explains why individuals have differing responses to stress; There is variability.
-By including a reappraisal process, this model accounts for the fact that our perception of stress may change.
-Proposes different methods of coping, managing psychological responses to stressors.
-Used human subjects.

Limitations:

-Difficult to test through experimental research because of subjectivity and variability.
-The primary and secondary appraisals often occur simultaneously and are therefore difficult to isolate in research.
-Does not account for the fact that a stress response can occur without having an appraisal.

Can someone please help with some questions from the 2014 paper?

Mikaela, a healthy adult female, is learning Italian for the first time.
Question 5
As she forms new memories of the Italian language, Mikaela is most likely to experience an increase in
A. the size of her amygdala.
B. gamma-amino butyric acid (GABA) levels.
C. the number of neurons in her hippocampus.
D. the number of neural connections in her temporal lobe.

I put C but the answer is D. Can someone explain why?

Also,

Question 18.
One of the complex tasks required Madeleine to complete a jigsaw puzzle.
During this task, the lobe of the brain that would show the greatest neuronal activation would be the
A. left frontal lobe.
B. left occipital lobe.
C. right parietal lobe.
D. right temporal lobe.

Answer is C. Can someone explain this as well. I said A.

Lastly, has someone completed the research methods section of this exam that got full marks or close to full marks?

THANKS so much!!

Q5. Good to see you immediately ruled out A and B. This question more or less is taking a plasticity perspective. Because she is an adult it is likely that pretty much all neural proliferation has occured. The main change at the synapse in learning is sprouting of dendritic connections, not proliferation (since this is characteristic of developmental plast).
Q18. I think they've thrown you with the word 'complex', which is good that you've linked this to option A. However, as you should know, the parietal lobe is critical to spatial reasoning (ie fitting a jigsaw piece into a puzzle by spatial recognition that its shape is complementary. It's easy to remember the function of this lobe because patients with damage to it have spatial neglect (obviously it must be linked to spatial awareness). As for the hemispheric choice, well the right is primarily dominant for spatial reasoning, and the left hemi controls more logical tasks like maths (doing a jigsaw doesn't require much ground-breaking thought, more just recognition of shapes and position.
Can't help on the research question, I only got 3 marks for the final 10 mark question...otherwise I could help on the hypothesis and stat question but I think you sound like you'd be okay with that! :)

Makes super sense thanks heaaaps your explanations are great! :D
And about that research question, it was the 10 marker that I struggled with as well. The last part about the p-value interpretation of results just wasn't explained well for me in the examiner report... Apparently no one got a full mark for that section, but then how to people get 50 SS...

I know this question has been asked a lot, but can someone please double confirm with me that you will not lose marks if you correctly operationalize a hypothesis when it asks for a research hypothesis?

It show's the percentage of people that got full marks (not the number of people, there's more than 100 people that did psych last year  ;) ). So there would of been a few that would of gotten full marks, but not enough to represent a rounded percentage of the state.

I know this question has been asked a lot, but can someone please double confirm with me that you will not lose marks if you correctly operationalize a hypothesis when it asks for a research hypothesis?
If you operationalize, you must do it correctly or you will lose marks, if you don't than that's fine, vcaa stated they only will only require a research hypothesis.

For section C, would it be okay to structure your writing in terms of the dot points they give you? So for each dot point, you use it as a subheading?

Certainly, as long as you elaborate a lot and make it informative. Personally however, I just write it in paragraphs so I can link ideas easily.

Can someone please help me with the strengths and limitations for the theories of forgetting? At least for Ebbinghaus forgetting curve? Thanks :)

How would you set up section c for the exam? Do you need to write an introduction or just go straight into listing the IVs and DVs etc.?
