Frowd- Internal and external features
- Experiment 1
- 30 staff and students from Stirling University
- Target photos of 10 celebrities and 40
composites
- The images were produced by E-FIT, PRO-fit, Sketch and EvoFIT
- The images were produced by E-FIT, PRO-fit, Sketch and EvoFIT
- Three sets of composites were used
- Complete set
- Internal features
- External Features
- Complete set
- Participants were tested individually, asked to place
composite infront of correct celebrity
- Whole composites and external features scored 35%, internal 19.5%
- 30 staff and students from Stirling University
- Experiment 2
- 48 undergraduates at Stirling University
- Photo array/photo line up
- Distracter faces and foils used either very
hard or very easy.
- Composties presented one at a time along with the photo array
- Participants had to then pick out the celebrity face from
the array which matched the composite.
- Again composties were either internal or external
- Again composties were either internal or external
- Participants had to then pick out the celebrity face from
the array which matched the composite.
- Composties presented one at a time along with the photo array
- Distracter faces and foils used either very
hard or very easy.
- Composties of external features 42%, internal
19.5%
- 48 undergraduates at Stirling University
- Experiment 3
- 54 volunteers for sorting task, 8 paid witnesses
- Familiar or unfamiliar target faces were presented to witnesses who created
PRO-fit composties
- Images were then photoshopped to create internal or external composites
- These then presented to sorters as before with whole faces
- These then presented to sorters as before with whole faces
- Images were then photoshopped to create internal or external composites
- Sorting was accurate at 57%, no difference between familiar
and unfamiliar.
- External 53%, internal 32%
- External 53%, internal 32%
- 54 volunteers for sorting task, 8 paid witnesses
