Recognition of unfamiliar faces across viewpoints
MetadataShow full item record
The present study investigated two main areas of face recognition. The first aim was to provide supportive evidence for the distinctiveness/fluency account of memory dissociation. Specifically, it hoped to find that: 1) rating faces for distinctiveness elicited more remember responses, and 2) sorting faces into categories elicited more know responses. Results showed a trend consistent with these predictions but this was not significant (p=0.288), and the null hypothesis was accepted. The second aim was to find supportive evidence for the so-called ‘mid-profile’ advantage in face recognition. The mid-profile was investigated in both same-angle (i.e., same angle at study and test) and different-angle (i.e., frontal at test and mid-profile at study or vice versa) conditions. This effect was not found in the same-angle data although the results showed the expected trend (p=0.08). In the different-angle data, recognition performance was found to be significantly better when faces were studied at frontal and tested at mid-profile view than when studied at mid-profile and tested at frontal view (p<0.05). This last effect has been interpreted as showing a test-view advantage for the mid-profile perspective.
