What is the Multistore memory model ?
Three memory stores. Sensory, STM, LTM To get information from Sensory to STM š”Ŗ PAY ATTENTION
To get information to remain in STM store š”Ŗ maintenance rehearsal
To get information from STM to LTM š”Ŗ Elaborative rehearsal
in what memory store can memory be displaced?
in the STM (short term memory)
can memory be retrieved?
yes
What are the critisisms of the multistore memory model
Ignores individual differences: e.g. some people have a large capacity
Oversimplified: oversimplifies the STM and LTM like its only one large store
Too much emphasis on rehearsal: doesnāt explain things like trauma
Clive Wearing case study (APRC)
Wilson, Kopelman and Kapur (2008) intended to report on the case of Clive Wearing who suffered severe anterograde and retrograde amnesia.
A longitudinal case study covering 21 years was conducted. The research gathered qualitative and quantitative data
The researcher used neuropsychological tests: such as IQ tests, tests of verbal fluency and a digit span test to test his long and short term memory.
MRI scans were used to see the amount of damage to Cliveās brain
Critisisms of Clive Wearing case study
Unethical: repeatedly using him as a subject over the 21 years as it would have been very distressing to CW.
Non-confidential: Although the authors refer to the patient as CW, they identify him by his first name and give enough personal background to make it clear who CW is. Therefore his identity was not kept private.
Cannot generalise: Clive may not have truly understood the study on him due to the extent of his brain damage ācannot generalise results as unique case
Summerise the reconstructive theory
The theory that memories are not exact copies of what is encoded and stored but are affected by prior experience and prior knowledge in the form of schema
What is confabulation?
making things up but not with the intention to deceive people.
critisms of the Reconstructive theory
Reductionist
Doesnāt explain how memories are processed
vague: The concept of schema is too hypothetical
Too many extraneous variables: during āwar of the ghostsā study standardised instructions not given
What was the aim of Braun et al study 1
To see whether autobiographically-focused
advertising could directly affect how consumers
remember a prior childhood experience.
What was the procedure of Braun et al study 1
week 1: ālife events inventoryā and filler tasks
week 2: participants again were given either the
Disney advert or non Disney advert and ālife events
inventoryā again.
What were the results of the Braun et al study 1
65% of participants in the experimental group
who received the autobiographical advert
mentioned memories of Disney world
90% of participants in the Disney advert group
showed an increase in their score on the life events
inventory in week 2 for the critical question
Critisisms of the Braun et al study 1
Age bias: students from USA
Not ethical: manipulated peoples memory
Study lacked ecological validity
What was the aim of Braun et al study 2
To see whether false information in an advertisement could make participants think that those events had happened to them as a child
What was the procedure of Braun et al study 2
Participants in the experimental group were given 2 different types of false information.
first advert: suggested meeting Bugs bunny second advert: suggested shaken hands with Ariel The control group:received a Disney advert which contained factual information
Participants then completed the life events inventory
What was the results of Braun et al study 2
The autobiographical adverts were more involving for participants than the non autobiographical one.
All three groups increased their confidence that they shook hands with their favourite TV character but higher in the experimental condition.
summarise the Situational factors theory
Situational factors theory: Proposes behavior is influenced by external circumstances rather than internal traits or characteristics. It emphasizes the impact of the environment on individual actions.
summarise the Dispositional factors theory
Dispositional factors theory suggests behavior is influenced by internal traits like personality, rather than external factors like situations.
What are the EXTERNAL FACTORS that explain why people conform.
Obedience= If a member of authority is present we are more likely to follow an instruction
Culture= Collectivist cultures are more pro-social. Individualistic cultures are less pro-social
Collective/crowd behaviour= Collective behaviour includes crowds, mobs, and riots. Crowds are a group of people who share a common concern in close proximity of each other. š”Ŗ leads to deindividuation
Normative/informational conformity= Normative conformity is you want to be liked. Informational conformity is you want to be right.
What are the DISPOSITIONAL FACTORS that explain why people conform.
Self Esteem- the greater the self esteem the lower the chances of being influenced
Locus of Control- High internal locus of control (feel they control their lives)= Less likely to be influenced and vice versa
Authoritarian Personality- People with Authoritarian personality are more likely to be influence and show obedience
Morality- People are most pro-social during higher stages of moral development
The Brain- People with dysfunctional hippocampus (affects self-esteem) and pre-frontal cortex (affects morality) may affect how influenced they are by others.
Critisisms of the Situational factors theory
over generalisations- Critics argue that the situational factors theory oversimplifies behavior by focusing solely on external factors, neglecting individual differences and personal agency.
Critisisms of the Dispositional factors theory
over generalisations- Challenges the theory's oversimplification of behavior, neglect of situational influences, and failure to account for individual differences.
subjective- difficult to test
What is the aim of Bickman study 1
To see if social power is associated with uniform
What is the procedure of Bickman study 1
Field experiment in New York ā confederate either wearing guards uniform, milkman's uniform or dressed as a civilian. Pedestrians were approached and asked to : pick up a paper bag, give a dime to a stranger for parking or stand at another bus stop pole.
What is the results of Bickman study 1
Participants listened more when the confederate was dressed as a guard
summarise Bickman study 2
Field experiment testing obedience to authority. the two IVās were surveillance vs non-surveillance.
Participants more likely to comply with a request from a person in a uniform.
summarise Bickman study 3A
A questionnaire was given with 29 different scenarios. Students were asked if the requests within the questionnaire were ālegitimateā or not depending on if it was asked by guard, civilian or milkman.
Critisisms of Bickman study 1, 2 and 3A
Lack of generalizability
Small sample sizes
Potential bias in data collection
Cultral Bias
Gender bias
What were the aims of the Natcen Mark Duggan study
The study aimed to see what had triggered the riots and the extent and nature of the youth involvement
What were the posedures of the Natcen Mark Duggan study
Data was gathered just 5 weeks after the riots had taken place Participants were interviewed individually, or in groups of 2 or 4. Full informed consent was gained and confidentiality was protected. 36 Tottenham participants were interviewed they varied in ages, ethnicities, work status and gender, with the vast majority still being in education.
What were the results of the Natcen Mark Duggan study
4 categories were created of different people involved in the riots. Watchers, Rioters, Looters, Non-involved
What were the conclution of the Natcen Mark Duggan study
Researchers identified ānudgeā factors (encouraging factors) and ātugā factors (discouraging factors). The researchers then divided these nudge and tug factors into dispositional (individual) and situational (social) factors.
Cririsisms of the Natcen Mark Duggan study
cant make generalisations- as only small proportion of people involved in riots - It was hardto recruit participants
Social desirable responses āMemory is unreliable
Summerise Freuds theory of dreaming
Freud believed dreams were repressed urges from the unconscious mind and that dreams were wish fulfilments of our deepest darkest wishes that couldnāt be fulfilled in real life. Freud claimed dreams have a manifest content and latent content.
What is Manafest content?
manifest content is the actual content of a dream
What is Latent content?
latent content the underlying meaning of the dream.
Criticisms of Freuds theory on dreaming
too subjective- different interpritations on dreams
The theory is difficult to test āThe theory id based on unreliable research and dreams are difficult to test
ReductionistāThe theory only relates to wish fulfilment when dreams can be more than that e.g. nightmares or things we are worried about.
What was the Aim of the Wolfman study
To try to reveal the latent content of the wolfmanās dream about wolves
What was the procedure of the Wolfman study
Longitudinal case study with interviews
What was the result of the Wolfman study
As a young child wolfman witnessed his parents having sex. The wolf symbolised his father. There was a Christmas theme surrounding the dream too e.g. white snow represented white bedsheets. Wolves represented the presents under the tree. Wolfman feared he would be castrated by his father
What was the conclution of the Wolfman study
Freud suggested that the wolfman repressed his fears (being castrated) and wishes (wanting to be seduced by his father) and this latent content was displaced into the manifest content within his dreams.
Critisisms of the Wolfman study
Reductionist- Cant make generalisations as this case study is only about the wolfman
Cannot objectively test- wolfman is unrepresentative due to his mental health issues
Inaccuracies in wolfman's dreams āmaybe wolfman didnāt accurately recall his dreams.
Sumerise the Activation synthesis hypothesis
Dreams are meaningless. The only reason people have dreams is because of random brain activity.
Signals arise from the pons (bundle of neurons) š”Ŗ This activates the limbic system (emotions)š”Ŗsignals travel to the occipital lobe (visuals) š”Ŗ Cerebral cortex stimulated (makes sense of brain activity by creating dreams)
what is the pons
It is a group of nerves that function as a connection between the cerebrum and cerebellum
what is the limbic system
the part of the brain involved in our behavioural and emotional responses
what is the occipital lobe
where you process visual stimuli from the external world while also assigning meaning to visual perceptions.
what it the Cerebral cortex
processing activities such as perception, language, memory, thinking and problem-solving.
Critisisms of the Activation synthesis hypothesis
Some people have recurring dreams of a similar theme, suggesting dreams arenāt completely random
This theory suggests that dreams are only activated in REM sleep but other research suggests dreamscan occur in non-REM sleep too.
too reductionist- dreams are complex and shouldnāt be reduced to just neuronal processes.
What were the aims of Williams study
To try to reveal the latent content of the wolfmanās dream about wolves
What were the prosedures of Williams study
12 participants (American students aged 23-45) ā participants Kept a dream journal (self-report) - 60 daydreams and 60 night dreams collected according to the number of number of lines
Experiment lasted 1 term āThe DV: bizarreness density was recorded according to locus and type of bizarreness āThree separate judges recorded the score in order to increase inter-rater reliability.
What were the results of Williams study
Significant difference between mean density scores for dreams and fantasies (the mean for dreams being 3X higher in bizarreness). -The most significant difference was on discontinuity. -The judges were 88.7% accurate on guessing if the report was a dream or fantasy (therefore the two must involve different cognitive activities)
What were the conclusion of Williams study
The bizarreness of dreams correlates with brain activity during REM sleep which is why dreams contain more ābizarrenessā ā night Dreaming and day fantasies involve two completely different types of brain activities. āBoth during night dreaming or daydreaming individuals donāt register external stimuli
Critisisms of Williams study
social desirability bias
lack of control over independent variable- (how can they only record dreams in REM sleep?) difficult to generalise- (12 participants and most were female)
lacks construct validity
