who made the multi-store model
Atkinson and Shiffrin (1968)
describe the multi-store model
information is picked up by the sensory register, if paid attention to the information is passed onto the STM where it is then stored for 18-30 seconds. if the information is rehearsed it can be transferred to the LTM which has unlimited capacity and duration. however if the information is not rehearsed whilst in the STM then retrieval failure can occur and the information can decay.
what is the AO3 of the MSM
strengths : KF case study, inspired further research
weaknesses: low ecological validity, over-simplified and vague
what are the 3 types of encoding
procedural (visual), acoustic and semantic
encoding, capacity and duration of sensory register
encoding - echoic
capacity - unlimited
duration - 250ms - 2s
encoding, capacity and duration of STM
encoding - acoustic
capacity - 5-9 items
duration - 18-30 seconds
encoding, capacity and duration of LTM
encoding - semantic
capacity - unlimited
duration - unlimited
three types of LTM
episodic - time stamped events (declarative)
semantic - encyclopedia/dictionary (declarative)
procedural - how we do things (non-declarative)
who created the working memory model
Baddeley and Hitch (1974)
describe the working memory model
central executive - dominant control
phonological loop - phonological store (inner ear) articulatory control system (inner mouth)
LTM
visuo-spatial sketchpad - dual-tasking (inner eye)
AO3 of the WMM
strengths : idea old dual-tasking is addressed
KF case study
weaknesses : still evolving (episodic buffer came along in 2000)
central executive’s role is vague
explanations for forgetting
retroactive interference - old information affecting your ability to recall new information
proactive interference - new information affecting your ability to recall old information
contextual cues - individuals are able to recall information better in the place they learnt it
factors that can affect the accuracy of eyewitness testimony
reconstructive memory, leading questions, anxiety and post-event discussion
how do you improve the accuracy of eyewitness testimonies?
through the use of cognitive interviews
the four techniques of cognitive interviews
recall everything - individual is asked to recall everything no matter how irrelevant they may deem
reinstate context - this is to return the interviewee to the emotional state they were in when the event took place to get situational context to aid memory
change order - change the order of events to aid memory
change perspective - ask the individual to recall from a different perspective to possibly aid memory
define conformity
a change in a person’s behaviour or opinion as a result of a real or imagined pressure from a person or group of people
the 3 types of conformity
internalisation - the changing of belief both publicly and privately to match the majority of the group (LONG-TERM)
identification - the changing of beliefs both publicly and privately but only in the presence of a group (short-term)
compliance - changing of behaviour to match the majority group however the beliefs do not change (temporary)
2 explanations for conformity
normative social influence - influence of people that leads us to conform due to wanting to be accepted
informational social influence - wanting to be right and looking to the group for the answer
3 factors affecting conformity
task difficulty
unanimity
group size
Asch’s line study
aim : to investigate whether social pressure would make a person conform
procedure : 123 male American undergraduates in groups of 6 with 5 confederates were asked to identify which line is most in comparison to the main line. real participant was always asked last or second to last and the confederates intentionally gave the wrong answer 12 out of 18 trials
findings : 75% conformed at least once, 36.8% conformed, 25% didn’t conform only 1% were incorrect
conclusion : most conformed to avoid rejection from majority even though they knew the right answer.
AO3 of Asch’s line study
strengths : high heuristic value, highly controlled
weaknesses : gender bias, population validity and deception
Zimbardo’s Stanford prison experiment
aim : To investigate how readily people would conform to the social roles in a simulated environment, and specifically, to investigate why ‘good people do bad things’
procedure : 24 American male undergraduates who were deemed ‘ mentally stable’ were selected and assigned roles of either prison guard or prisoner. both had uniforms and the prisoners were referred to as only their numbers in a mock prison set up in the basement of the psychology department. guards were given handcuffs and sunglasses to reinforce boundaries
findings : guards became increasingly brutal and aggressive, some admitted to enjoying their roles. The guards became more demanding of obedience and assertiveness towards the prisoners while the prisoners became more submissive
conclusion : the uniforms created a loss of personal identity and social roles had a strong influence on the individuals behaviours
AO3 of Zimbardo’s experiment
strengths :
real life application- this research changed the way actual US prisons are run
-the ppts were fully debriefed about the aims and results of the study
-highly controlled
weaknesses :
-protection from harm
-gender bias, lacks population validity
-demand characteristics, ppts knew they were participating in the study
what is the agentic state?
a mental state where we feel no personal responsibility for our behaviour because we believe we are acting for an authority figure
what is legitimacy of authority
an explanation for obedience which suggests that we are more likely to obey people who we perceive to have authority over us
Milgram’s shock experiment
aim : To observe whether people would obey a figure of authority when told to harm another person i.e. evaluating the influence of a
destructive authority figure.
procedure : 40 male volunteers were assigned either the role of a teacher or learner, ppts were asked a series of questions when the confederates got an answer wrong the ppt was asked to shock the confederate
findings : 65% continued to the highest of 450V , all continued to 300V
conclusion : ordinary people are likely to follow orders given by an authority figure
AO3 of Milgram’s shock experiment
strengths : real life application- it could reduce future obedience in response to destructive authority figures.
-high control
-ppts were fully debriefed on the real aims of the study
weaknesses : no right to withdraw, no protection from psychological harm
-gender bias
-ecological validity, tasks given are not like those we would encounter everyday
the authoritarian personality
a person with high respect for authority and is more likely to be obedient to those who hold power over them
what is social support
the presence of people who resist pressures to conform or obey can help others to do the same
resistance to social influence: what is the locus of control?
a measurement of an individuals sense of control over their lives
internal locus of control
(more control) their behaviour is caused by their own personal decisions and effort
external locus of control
(less control) behaviour is caused by luck or fate
the 3 main processes in minority influence
consistency - the influence of a minority is most effective when it is consistent and when the minority have so much passion and confidence in their point of view, it suggests to the majority that their view must somehow be valid.
commitment - engaging in quite extreme activities
flexibility - majority opinions shifts more if the minority is flexible
what is social change?
when whole societies rather than just individuals adopt new attitudes, beliefs and ways of doing things.
what is the snowball effect?
when a minority succeeds in attracting enough supporters, it is transformed into the new majority
definition of attachment
a strong reciprocal emotional bond between an infant and a primary care giver
definition of reciprocity
a two way, mutual, infant led interaction between infant and caregiver
definition of interactional synchrony
a coordinated interaction led by the infant between infant and caregiver (mirrored actions and emotions)
Schaffer and Emerson (1964) stages of attachment
aim - To identify stages of attachment
procedure - longitudinal study in which 60 infants from Glasgow were analysed in their homes with family once a month for 12 months and then again at 18 months. their interactions were analysed, the carers were interviewed and the carers had a diary to track the infants behaviours.
findings - by 7-8 months, 50% of the babies showed separation anxiety towards mothers. by 10 months, 80% had a specific attachment and 30% had multiple.
conclusion - attachments develop through a series o stages
AO3 of Schaffer and Emerson’s stages of attachment
strengths:
-longitudinal study
-ecological validity (done in a natural environment, reduces demand c)
weaknesses:
-lacks population validity (infants all came from Glasgow and possibly working class families)
-asocial stage cant be studied as objectively (infants as young as 6 months lack basic motor skills, we cannot interpret their separation anxiety as deliberate)
-lacks internal validity (uses self-report technique therefore the accuracy of the data collection may not be the best)
