2 - Steblay: tests of sequential lineup superiority effect

Question 1

What is the aim of this review?

Answer 1

To reassess the sequential-superiority hypothesis

Question 2

What did they find for target-present conditions?

Answer 2

Simultaneous lineups led to significantly more correct identifications of the culprit compared to sequential lineups

Question 3

What did they find for target-absent conditions?

Answer 3

Sequential lineups resulted in significantly more correct rejections when the culprit was not present

Question 3

How do sequential and simultaneous differ in diagnosticity ratio?

Answer 3

Sequential lineups have a higher diagnosticity ratio
-> meaning identifications made under the sequential format are more likely to be accurate

Question 4

Which lineup is more affected by the innocent suspect risk?

Answer 4

When you include a similar-looking innocent person in the lineup

Sequential lineup again shows higher diagnosticity
-> less risk of misidentifying an innocent person

Question 5

What determines the superiority of sequential lineups?

Answer 5

It’s higher diagnosticity ratio
-> when a suspect is identified, the likelihood they are guilty is higher
