Pozullo Et al (Methods) Flashcards
1
Q
What was the aim of the study?
A
- 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.
2
Q
What were the 4 predictions/hypothesis of Pozzulo’s study?
A
- Children will be as good as adults at identifying catoon faces in target-present line ups.
- Children will be worse than adults at identifying human faces in target-present line ups
- Children will be worse than adults at rejecting cartoon faces in target-absent line ups
- Children will be worse than adults at rejecting human faces in target-absent line ups
3
Q
What was the research design?
A
Lab experiment
4
Q
Name the 3 ivs
A
- Age
- Line up type
- Level of cognitive demand
5
Q
Explain the 3 ivs
A
- 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
6
Q
What was the experimental design?
A
- Age: Comaparisons between adults and children= IMD
- Line up types: Comparisons between line up types= RMD
- Level of cognitive demand: RMD
7
Q
What is the dependent varible?
A
- Whether ppts idenitfied the correct face when present
- Or the empty silhoutte if absent
8
Q
Materials used?
A
- Black and white photo arrays (tightly cropped for cartoons, head and sholder images for humans)
- Video clips
