Studies paper 3 Flashcards
Maass and Köhnken
86 psych students
Woman holding pen/syringe
Independent groups choose woman from lineup
Remembered less facial detail the greater their fear of injections
Syringe condition -poor identification
Cook and Wilding
Carried out to see if ppl remember more when they hear something from a well known voice or voice they have heard only once.
Found little difference
Anderson and Dill
Aim investigate effects of video game violence
Procedure 1. Survey to link likelihood of playing games with admitting to aggressive bhr.
2 lab exp 210ppt. Matched on high to low irritability one group plays violent another plays nonviolent. Violent condition more aggressive (noise blast)
Viovideograms more harmful than violent tv
More interactive and identifies with game person
Evaluate Anderson dill
S
2 different research methods e.g. - reliable same results
Replicable explain
W
Measures of aggression not standardised, did not find sig. Results in all their measures
A & D looked immediately after so unable to see whether effect is long lasting
Yarmey
Aim - effectiveness of ewt in males and females in terms of photo identification.
Procedure - 215 m and 375 f ,age range18-70, approached by target (look jewellery/ask directions), 2mins later f researcher asks to take part, either ask on spot or 4hrs later.
16 phys characteristic questionnaire confidence rating on 7pt scale then given 6photos asked to identify target
Results - 49% identified correctly, 62% said target not there correctly
Conclusion - cast doubts on assumption that jurors should accept ewt
Evaluate Yarmey
S
Support haber and haber findings (50% accurate) so reliable
Carried out in natural environment-ecological validity
Range of ages generalizable and controls explain
W
Found age better identified than height & weight, contradicts Yuille and cutshall so not all studies support one another.
Photo lineup not same as real one -task lacks validity
Focuses on situation where ppt has met and spoken, not always the case for eyewitness, so should only be applied to similar situations
Loftus & Palmer exp 1
Aim - see if phrasing would affect estimates of speed.
Procedure - 45 students shown 7 films each film lasting 5-30 secs. After every film given questionnaire, critical question was asking estimate of speeds.
Results smashed 40.8mph contacted 31.8mph
Conclusion leading questions can affect answer
Loftus and Palmer exp 2
Procedure 150 ppt shown film with multiple car accident
Questionnaire asked ppt speed of car using word smashed and another hit.
One week later asked did you see any broken glass
Results smashed gave more yes answers
Conclusion way question asked can affect answer given. Verbal labels cause shift in memory to fit with label.
Evaluation loftus and Palmer
S
Lab exp with clear controls (pps watch same film, same questions with one word change)
Estimates of speed are quantitative no need for interpretation so study is objective.
W
Not same emotional strain between watching and actually witnessing so not valid
Students as ppt not generalizable
Demand characteristics since students can work out hypothesis and answered accordingly
Yuille and cutshall
Aim record ewt and examine accuracy of witness verbatim accounts, compare police vs researcher interviews
Procedure 20/21 witnesses contacted and 13 agreed to ppt, interviewed by police and by researchers 4/5 months later, 2 misleading questions (a/the broken headlight&yellow 1/4 panel)
Results researchers more detail than police 84.56% central witnesses accurate than peripheral 79.31 remained similar after 4 months. Misleading question had little effect.
Conclusion may have been investigating flashbulb memory ewt should not entirely be rejected.
Evaluate Yuille and cutshall
S
Field study with real witness valid than the lab exps. Such as loftus and Palmer
Careful scoring procedures research compared with police so reliable
W
Could be flashbulb - different to what the lab studies were testing, cannot generalize to criticize
Scoring quali into quanti data always involve bias due to interpretation involved (how many action details)
Jahoda
Studied Ashanti boys.
Kwadwo born on a Monday labelled quiet and peaceful
Kwadku born weds. Aggressive
Weds. Ppl higher arrest rate 22%
Evaluate jahoda
S
Valid from court records
Difference in name is clear
W
Not replicated
Could be other factors besides the name
Madon
Aim look at sfp in natural situation outside educ. Setting, whether accuracy of mom expc. Limit sfp
Procedure 505 mother child pairs
Longitudinal (questionnaire and interview)
Baseline measures is mother expectation of child future alcohol use(confidentiality guaranteed)
18mnth follow up -measure of child’s alcohol use
Results 52% relationship between mom expc and child alcohol use down to accurate maternal expectation, 48% down to sel fulfilling effects
Conclu high self esteem kids more susceptible to sfp and sfp are helpful rather than harmful
Evaluate madon
S
Expc are naturally occurring more valid
Longitudinal design to show cause and effect to a certain extent (measured moms expc first)
W
Natural studies do not show cause and effect the way experiments do, SFP involves cause of bhr.
Rosenthal and Jacobson
Pupils did IQ test
Randomly selected students about to bloom
Teachers thought predictions from IQ test but isn’t
Labelled about to bloom improved IQ score
Concluded teachers may treat differently special attention pupils more confident and so did better
Evaluate rosenthal
S
Well controlled (teachers don’t know random IQ results)
Replicable carefully planned
W
Not ethical to choose children not every kid receives special attention bcos of study
Ainsworth
Aim to observe attachment types between mom and babies
Structured obs. Film and observed through 1way mirror
66% securely attached 22%anxious avoid. 12%anx. Resis.
Jin mi kyoung studied Korean vs American proportions of ATt types are similar across cultures
Grossman more avoidant in Germany than Baltimore
