AQA A Level Psychology Paper 2 2019 Unofficial mark scheme

If the number was very close (4700) to 5000 it is plausible that it’s 86% increase

SAMEEE!! I dont get how it would be 86 or 90???

Anyone remember the numbers for the percentage increase question???

ME TOO it was 4 marks so I was like Spearman’s Rho because independent designs, correlations data, ordinal data

the numbers were 2500 something and 4688 I think therefore 54% would be reasonable as the the first percentage was roughly half the second

Yeah that's what I got aswell. It can't be anything else because it's nominal data. It's not ordinal because the researcher calculated the difference between the ratings. So it's no longer a rating, its a nominal score x

Sameee. Cos in bio we learnt that relay n are in the cns (brain+spinal chord) and also that they connect sensory to motor. So A and A. And then motor to effector so C

the numbers were 2500 something and 4688 I think therefore 54% would be reasonable as the the first percentage was roughly half the second

I did relay , motor , relay

Same :/

ME TOO it was 4 marks so I was like Spearman’s Rho because independent designs, correlations data, ordinal data

Wait I thought it was chi squared because the data was nominal not ordinal due to the fact it was categorical and named, there was no ranking or anything so how is that ordinal data??

I got unrealated t test and 86%, the happiness questionnaire generated a score

I think im the only one confused with that sign test table. Because i know the standard thing for sign test is to minus the two numbers from each other to see if theres an improvement or not ( + or -) but the title of the table labelled the results as ' Improvement scores'. So did they already find the difference for us? Which makes no sense i know but ififefmpdoaosdjasnda. i dont think anyone understands me tbh lol

ME too!

Approaches

MCQ - Genotype I got A I think I actually don’t remember
MCQ-
Operant conditioning
I did negative and postive reinforcement increase likelihood of behaviour reproduced

Outline unconscious structure - ID - pleasures Ego- reality Superego- morality ( I missed this cause I blanked) but only 2 makes

SLT - mediational processes for tiger advert

Use SLT to see why advertiser used rugs by player and paid him-
symbolic model - identify and imitate and purchase

Percentage - sales score
I got 86.6% rounded to 90% to significant figures

Women scored less sales - how could ad be improved to increase them
Women model in advert included - same sex model - imitate and buy product

Outline and Evaluate Wundts role to psychology as a science
Answer:First to see as science Introspection - emotional and mental states study process strength - useful c hunter(2003) helped used happiness as measure
Limitation - unrealistic - Pavlov and Thorndicke already using scientific method so wundts approach ignored and limited (I’m just helping I don’t know if it’s right.


There was the different neurons in biopsych.
I got the A as relay neuron
B as the sensory neuron
C as motor neuron
I studied the neuron picture in AQA cat book

Give gland and hormone and function of endocrine system - not allowed adrenals gland or adrenaline
I said pituitary - master gland
Secrete hormones to trigger other hormones

The essay was Sam and Kieran - hemispheric lateralisation/or localisation
I said sperry and Gazaniga )1967)
Corpus callosum makes brain work as one supports Sam point
Dog and cat - visual field and findings
Could speak and say dog when presneted to right
Not speak when cat shown to left
Right hemisphere - facial recognition
Left hemisphere speech and language
Findings -

supports Kieran
Ao3 :
Split brain Barely used now
- Andrew - small sample - unrepresentative- lacks validity etc

Limitation -
Not only speak from right side - goes against Kieran and supports Sam
Turk at al (2013) found j.w can speak out of right
So disconfirms their research but Gazznagiga (1981) acknowledged that and understood

Localisation
Broca left frontal lobe - speech
wernicke left temporal lobe - understanding language
Other localised areas
Strength - apashia studies
Expressive broca
Receptive Wernixke
What I think I wrote


Research methods -
MCQ - what’s is reliability - consistency
Not used in peer review -See if research needs funding
why does scientific report used reference? Idk so no one steals their data or plagiarism - I literally don’t know

What type of hypothesis for team/independent activity -Answer: non directional as no study like it before - also it’s 2 tailed as the sign test question after the critical value table was only for 2-tailed test


Write an hypothesis for study- make sure state there will be difference between group a and b and it’s all operationalised


Sampling method and limitation - opportunity- unrepresentative bias - lacks ecological validity cannot generalise

Matched pairs design - example of variable matched and how the groups assigned
Answer: Sport ability - should’ve dont age but didn’t cause it eww students and also Couslve been gender
random allocation Specifically 1 info group a first then 1 in group b and till 10 in each group

Concurrent validity - previous research - it measures using that test like that forgot the definition with key themes

Explain why lacks validity as researcher knew who was assigned to which group Researcher bias - own aims plus flaw results etc


Use answer from 25 and explain how this could be clear with to increase internal validity Answer : Double blind design - less bias


Sign test - s value -
Answer: I think I got 3 - I forgot which way difference was

Is there significant difference
Answer - I got N as 8 and CV as 0 on table Therefore no significant as s (3) was larger than critical value of 0 at 5% significance level!

Psychology teacher copy the researcher - 30 students
What test should she use -
Answer - 4 marksMann Whitney Test of difference Design independent so unrelated Data was I think nominal or ordinal - forgot what I put The 12 marker own study for the psychology study
