Pozullo Et al (Methods)

Question 1

What was the aim of the study?

Answer 1

• To investigate whether false identifications in target-absent lineups are more influenced by social pressures rather than cognitive abilities.
• To investigate if children are less able to recognize human faces than adults.

Question 2

What were the 4 predictions/hypothesis of Pozzulo’s study?

Answer 2

1. Children will be as good as adults at identifying catoon faces in target-present line ups.
2. Children will be worse than adults at identifying human faces in target-present line ups
3. Children will be worse than adults at rejecting cartoon faces in target-absent line ups
4. Children will be worse than adults at rejecting human faces in target-absent line ups

Question 3

What was the research design?

Answer 3

Lab experiment

Question 4

Name the 3 ivs

Answer 4

• Age
• Line up type
• Level of cognitive demand

Question 5

Explain the 3 ivs

Answer 5

• Age ( children vs adults)
• Line up type (Identification of target-present) (rejection of target-absent)
• Level of cognitive demand (Familarity with the target= low) (Human= high)

Low cognitive demand trials= results are due to social influences

Question 6

What was the experimental design?

Answer 6

• Age: Comaparisons between adults and children= IMD
• Line up types: Comparisons between line up types= RMD
• Level of cognitive demand: RMD

Question 7

What is the dependent varible?

Answer 7

• Whether ppts idenitfied the correct face when present
• Or the empty silhoutte if absent

Question 8

Materials used?

Answer 8

• Black and white photo arrays (tightly cropped for cartoons, head and sholder images for humans)
• Video clips
