the effect of age on EWT
Brassard -found that younger children (4 year olds) were more likely to be affected by the cues given by the interviewer than older children (8 year olds).
Memon et al -found that the accuracy of 60-82 year olds dropped when identification was delayed for a week.
Parker and Carranza- found that primary school children were more likely to choose someone from a mock up line, but they were also more likely to make errors.
Yarney-compared young and old adults and found that older adults were less confident but not less acurate when recalling aconfederate.
Anastasi and Rhodes-Found that younger (18-25) and middle age (35-45) were more accurate in identifying the target faces than older adults (55-78)
Own age bias - the apparent superior performance of younger adults may have been because the faces to be recognised were from their age groups-
Anastasi and Rhodes also found that all age groups were accurate in identifying target photographs from their age group.
Brigham and Melpas - different experience hypothesis -the less contact we have with people from different age groups, the poorer our ability to discriminate between indivilduals in this groups.
Contrived studies -pps may not behave as they would in everyday life.May not take task seriously or may look for cues.
