  • 1. Factors affecting the accuracy of EWT AGE!
  • 2. Children are morewilling than adults to …but they are often wrong make an Dekle et al (1996) identification… Children are It’s not just children… unreliable eyewitnesses Older people also because they areperform worse on EWT more susceptible to studies than young or the post-eventmiddle-aged participants effect Old men - Which is? in particular
  • 3. Age - researchPoole & Lindsay (2001) AIM: - Source Monitoring To investigate the effect of age on the Source accuracy of EWT monitoring is whether or not someone can identify the origin of the information i.e. where they heard/saw it first
  • 4. Age - researchPROCEDURE:Children aged 3-8 – watched science demonstrationParents read children a story (which included some elementof the science demonstration and some new information)Children questioned about original sciencedemonstration, found they incorporated much of the newinformation from the parent’s story – children wereasked to identify the origin of the information (this iscalled source monitoring)The researchers were interested in whether the children couldsource monitor and distinguish between information from thescience demo and information from the story
  • 5. Age - researchFINDINGS:Older children revised their account of the sciencedemonstration and removed the post-event informationYounger children were not able to do thisCONCLUSIONS:Because the young children weren’t able to distinguishwhere the information came from, it is concluded thatchildren are poor at source monitoringIt can be implied from this that older children are morelikely to give more accurate accounts of events, whilstEWT from a young child is more likely to be lessaccurate and therefore less reliable
  • 6. Age – research evaluation What type of experiment did What’s good about this? Poole andLindsay conduct? What’s not so Who were the good participants? about Ethical considerations? this?
  • 7. Age evaluation High ecological validity For example, it was conducted in a real life natural setting This a strength because the findings can be This means thatgeneralised beyond the researchers the research were investigating real life behavioursetting and applied to real life EWT
  • 8. Age evaluationEthical Issues For example, the participants were children and therefore unable to give fully informed consentThis a strength because This means thatresearchers had the parents ofparents actively the children involved and involved were required to give consent was consent gathered
  • 9. Age evaluation Low control For example, variables such as light, time of day etc were not controlled This a weakness because it suggests that This means thatresearchers cannot the research hasestablish cause and low internal validity effect betweenthe IV and the DV
