  • 1. PSYA1: Cognitive Psychology Memory Age & Eye Witness Testimony Miss Russell
  • 2. Thinking Ladder… To & what the own age bias is. To research into how age affects EWT. To Loftus’ research into the effect of age into EWT.
  • 3. How will I know if I am learning? By the end of the lesson… E Will be able to define the own age bias. C Will be able to explain how age affects EWT. A Will be able to evaluate research into the effects of age on EWT.
  • 4. Read the article on a child eye witness. What does this suggest about children as eye witnesses? How reliable are they? Warning There is some potentially traumatic material in the article. If you feel uncomfortable, leave the article and think about the potential flaws of using children as eye witnesses.
  • 5. Look in your envelope. There are lots of cards with different pieces of research into age and EWT. Sort them into research that suggests older eye witnesses are more accurate, and research that suggests younger witnesses are accurate. Summarise the findings in your table. Older EW’s are most accurate Younger EW’s are most accurate How conclusive is the evidence? Why might this be?
  • 6. Can you think of any methodological evaluation points of any of these findings? Hint: What about ethical issues regarding children?
  • 7. The majority of studies have tested college age students who were asked to identify same age targets. Studies which have tested older adults have also used college students as targets. Anastasi & Rhodes (2006) used individuals from three age groups. They had to rate 24 individuals (from different age groups) for attractiveness. Later they were presented with 48 photos: 24 they had seen previously, and 24 distractors.
  • 8. Young Photos Middle Aged Photos Older Photos Young Participants 90 87 85 Middle Aged Participants 85 93 87 Older 56 62 Participants % of correct recognition in each age group. 66 What do these results imply about age of the participant and age of the target?
  • 9. Apparent age effects may be due to the fact that people do best when asked to identify people of their own age group. Perhaps this is because we have more contact with people who are a similar age to us. The lesser experience we have, the greater the own age bias. When we encounter people of our own age group more regularly we become better at processing those faces and therefore have better memory for them.
  • 10. Summarise the Own Age Bias and supporting research in your workbook.
  • 11. : Factors Affecting Eye Witnesses   You’re a psychologist advising the police on how to deal with their witnesses. An old woman and young man have just been witnesses to a middle aged man holding a store up with a gun. The old woman was behind the gun-man in the queue but the young man was outside the shop and could only see through the top half of a window. With reference to this situation, advise the police on what problems they might encounter and fill in the simple advice grid below so they can work with it easily and come back to it when they need to revise their knowledge. Look at the table in your booklet. Try to summarise all the information you have learned over the past few lessons on factors which influence EWT.
  • 12. To what extent does age influence the accuracy of eyewitness accounts? (12 marks)
  • 13. And finally – Using Psychological research, answer the following question. How does age influence the accuracy of EWT (4 marks). Now Peer Assess your answers. Swap your answers and mark them out of 4.
