Bruce and Young (1998) EWT

Aim: To examine the ability of pps to identify faces from videos security devices 

Method: pps watched 10 video clips twice of members of uni deot coming in and out of a building 

  • They then were shown pictures of people faces they had to say whether they had seen them or not using a scale:Independant Variable 
  • Some pps knew the members of staff 
  • Some pps didnt know the staff
  • Some were police officers

Results: The pps who knew the people on video were good at identifying the from the pictures. 2 other groups found it difficult to identify the people they saw or did not see on the video clips

Conclusion: Familarity with the target on the video clip had a large effect on identification

Evaluation: +Study wa well controlled, Burton can be confident that the familiarity affected the ratings given for each picture

- Less pps could make it difficult to generalise. Could be pps variable in each group affecting the ratings rather han familairty

- Rating system is subjective, rating of 5 from 1 pps may not be the same rating of 5 from another
