Social Approach
The Key Question
How can the social approach to psychology help explain the atrocities of Abu Ghraib in 2004?
Use theories of obedience and prejudice to explain the behaviour shown by guards and prisoners after the events of 9/11
Always relate any theories or psychological concepts to the above contemporary issue.
Use the work of Milgram, Tajfel, Sherif, Latane and Zimbardo amongst others
Social Psychology
Theories of Obedience
Definition of Obedience
The Agency Theory (Milgram 1965)
Describe (4xA01)
● Blind obedience● Moral strain● Perception of authority figure● Actions are the responsibility of another● Agentic v autonomous obedience
The Social Impact Theory (Latane 1981)
Describe (4xAO1)
● SxIxN● Strength of Impact● Immediacy of Impact● Number of Sources
Explain genocide using the agency theory of obedience
Extend your explanation to include the Social Impact Theory

The Key Social Question
What caused the behaviour of prisoners and guards in Abu Ghraib 2004?
Ensure clarity through the use of paragraphs
Describe the issue (4 AO1s) using 4-6 clearly differing points of fact

Use the work of
Bartlett, Loftus, Atkinson/Shiffrin, Allport/Postman amongst others to view both sides of this argument
Theories of memory
Multi Store Model of Memory - Atkinson and Shiffrin (1968)
Diagram
General description
● 3 stores ● Maintenance rehearsal to keep the thought in STM
● Elaborative rehearsal to store a thought as an engram. This transfers from the STM to the LTM (structural change to brain)
● Retrieval from LTM to STM if the engram is being ‘worked with’ and is required
Features of each store – Task, Capacity, Duration
Short Term Sensory Store
(STSS)
● Acts as a buffer system for the vast incoming stimuli (Task)
●
●
Short Term Memory
(STM)
●
● Capacity of 5-9 items (Capacity)
●
Long Term
Memory
(LTM)

Analysis of qualitative data
Qualitative data comes from open questions or un/semi structured interviews. It is a way of taking rich, in depth data and attempting to give it some sort of measurement to allow reliable analysis.
e.g How prejudiced is this individual from the transcript/question response?
Thematic analysis is the most common form of analysis in qualitative research . It emphasizes pinpointing, examining, and recording patterns (or "themes") within data.
Themes are patterns across data sets that are important to the description of a phenomenon and are associated to a specific research question. The themes become the categories for analysis.
Thematic analysis is performed through the process of coding in six phases to create established, meaningful patterns.
These phases are:
● familiarization with data, ● generating initial codes, ● searching for themes among codes, ● reviewing themes, ● defining and naming themes, ● and producing the final report●
Below is an article written by an American attorney. You have to decide to what extent it could be considered racist.
● http://www.amren.com/features/2014/05/confessions-of-a-public-defender/Research definitions of racism and generate 3 initial codes (key pointers of casual racism)
Read the article once to familiarise yourself and then as a pair colour code the argument.
Score the article as below
A – Racist (Red)
B – Undecided (Yellow)
C – Not racist (Green)
To what extent is the article racist?

When evaluating, consider strengths and weaknesses. Base these on two spectrums
Ecological Validity
(To what extent the findings are representative of real life scenarios)
Consider
● The mundane realism of the task(s) in the experiment. Are they normal day to day activities
● The artificiality of the settingLow ___________________________________________________ High

Extraneous Variables
Give examples of the following
Participant variables
Situational variables
Controls
A psychologist must attempt to ensure that any possible extraneous variables are controlled to avoid a confounding variable affecting the results.
Draw a diagram below to show this process and then explain how a confounding variable could affect the results of a memory test on colour identification of 5 year olds.

Operationalisation of the independent and dependent variables
The op of the IV
The IV is the aspect of change between conditions or groups
For example
Condition – Using imagery to improve memory recall
Groups – Older peoples performance in memory recall
The operationalisation of the IV considers how you would introduce this change
For example
Imagery – Is operationalised by attaching a corresponding photo of the word to the list to be recalled
Age – Is operationalised by grouping all people 18 years and over as older, and 17 and below as younger
The operationalisation of the IV must be absolutely specific to the experiment at hand
Operationalise the following IVs when considering an experiment into memory recall of a list of 20 words
● The time of day____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
● Ethnicity
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
● Climate____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
The operationalisation (op) of the DV
After the IV has been introduced, (the cause), we then measure the effect. The way in which you measure the results is known as the op of the DV. It must
● Clearly state what you are measuring● How you will measure it
● And what scale of measurement you will be using eg number of correctly recalled words between 0 – 20
Operationalise the following dependent variables
1. Prejudice
2. Aggression
3. Independence
4. Obesity
Hypotheses
A hypothesis is a statement of what will or will not happen.
It is a prediction of what you believe or do not believe will occur to the DV when the IV is introduced.
Experimental or alternate hypothesis
If you are conducting a laboratory, field or natural experiment, then you state
‘The experimental hypothesis is …’
If you are conducting a non- experimental study such as an observation or survey, then you state
‘The alternate hypothesis is …’
Directional or non-directional hypothesis
A directional hypothesis states the IV will affect the DV in one definite way. This is known as a one tailed hypothesis
E.g. The one tailed experimental hypothesis is that a rainy day will lower the happiness rating of people
A non-directional hypothesis states the IV will affect the DV, but is unsure which. This is known as a two tailed hypothesis
E.g. The two tailed experimental hypothesis is that a rainy day will affect the happiness rating of people
The null hypothesis
A null hypothesis states that there will be no significant effect of the IV on the DV
E.g. The null hypothesis is that a rainy day will have no significant effect on the happiness rating of people
Effect of Results on the Hypothesis
Using either descriptive or inferential statistics, you accept or reject your one or two tailed hypothesis.
If you accept either the one/two tailed, you reject the null
If you reject either the one/two tailed, you must accept the null

Experimental and research design
Independent Groups
When the sample of participants is split into 2 or more groups
The control group (DV measured) and experimental group (IV introduced, DV measured)
E.g. Short participants throw and catch a ball against a wall. Tall participants do the same. The op of the DV is how many are caught. The op of the IV is in cms. Short is 170 cms and below, tall is 171 cms and above
Matched Pairs
This is the same as independent groups but where a possibly confounding participant variable is controlled.
E.g. The average IQ of group A matches the average IQ of group B when the sample is split and tested on learning a new language either online or with a teacher
Repeated Measures
When the sample group remains whole but carries out the control test followed by the experimental test (or vice versa)
E.g. The group learn French online followed by Italian with a teacher over 2 x 60 hour courses
Outline one possible experiment you could carry out using independent groups
Outline one where you feel matched pairs would be preferable
Outline one where repeated measures would need to be employed
Order Effects
Using repeated measures has one main weakness. Order effects
They occur when condition A influences the results in test B
Example One
Practice effect…where performance in test A improves or hinders performance in test B
Explain a detrimental effect using the recall of words in a list (control) and similar words with corresponding images (experimental)
Example Two
Fatigue effect … where performance in test B hinders performance in test A due to either physical or psychological tiredness. Explain using a physiological IV on a psychological DV
In order to control possible order effects which could confound results and damage the internal validity of results, the following techniques are used.
Counterbalancing
Split the sample in half
Group 1 carry out test A then B
Group 2 carry out test B then A
This balances any possible positive or negative effects on the D.V
Randomisation
This can operate should there be more than 2 conditions
A-B-C, C-A-B, B-C-A
This aids validity to a greater extent as all possible combinations lessen order effects.
A = words only B = images only C = words and images only
Situational and Participant Variables
These extraneous variables occur more often when there is less control over the experiment. They lower the internal reliability of any study.
Experiments
Laboratory Field Natural
<--------------------------------------------------------------------------------------------------------
High Reliability less Reliability Low Reliability
Examples of Situational Variables Examples of Participant Variables
Reliability
The extent to which a study could be identically replicated
Validity
The extent to which the operationalisation of the variables (IV and DV) measure what they intended to measure.
Thought
Is it possible to have one without the other in terms of reliability and validity?
Answer this fully and correctly and you are a fully-fledged member of the clever party
Research the following
Researcher effects
What are they?
Give examples
Demand Characteristics
What are they?
Give examples
Draw a diagram to show how researchers attempt to protect the IV’s effect on the DV
Inferential Statistics
● Statistical analysis of raw results ● Testing to what extent the results may be down to chance● Offering a statement of probability and certainty regarding the hypothesis
Levels of significance
p < 99% or 0.01 states that there is a 1% chance that the results were down to chance and not the result of the IV on the DV (the cause on the effect)
p < 95% or 0.05 states that there is a 5% chance that the results were down to chance and not the result of the IV on the DV (the cause on the effect)
Statistical analysis must be stringent to at least 95% certainty to accept an experimental/alternate hypothesis. If it does not reach this level, the null hypothesis must be accepted.
For particularly sensitive research, such as anti-psychotic drugs, testing must be much more rigorous than p > 0.01
Which test should I use?
Follow the 3 D method. Consider the study at hand and answer the following questions
Difference or Correlation
Is this a test of cause and effect, or strength of association between variables?
Design
Is this independent groups/matched pairs or repeated measures?
Data
Is the raw data nominal or ordinal?
Nominal data – Tally data, basic data
Ordinal/Interval data – The data can be rank ordered from the lowest to highest score
If it is a one tailed hypothesis, we test to p > 95% or p < 0.05If it is a two tailed hypothesis, we split the rejection of the hypothesis into two, as there are two possible outcomes. p here
would only be p > 90% or 0.10
Observed and Critical Values
The critical value is the point at which a hypothesis can be accepted or rejected. It is a purely statistical point and has nothing to do with the behavioural element of
many studies.
Hypothesis testing for reliability
1. Decide which test is appropriate for your study (3Ds)2. Gather your raw data and calculate the observed value. This can be done easily
online although the exam will ask for some aspect of the test to be completed manually.
3. Have your hypothesis at hand4. Remember how many participants (N) took part
5. Decide which level of significance you wish to test for6. Go to the correct statistical table, compare the observed and critical values, and
claim (or otherwise) significance of results7. If the results are significant, accept the directional hypothesis. If they are not, reject it
and accept the null hypothesisWhich Test?
Type I Error
A type I error occurs when one rejects the null hypothesis when it is true. The probability of a type I error is the level of significance of the test of hypothesis, and is denoted by *alpha* (a).
Type II Error
A type II error occurs when one rejects the alternative hypothesis (fails to reject the null hypothesis) when the alternative hypothesis is true. The probability of a type II error is
denoted by *beta* (b)

The Learning Approach
The Observation
● ensure that observations relate to an aspect of learnedbehaviour, such as behaviour of different sexes, drivingcharacteristics, age-related behaviour, politeness and
helping behaviour
● ensure that observations enable the gathering of bothqualitative and quantitative data (including the use of note
