The Cambridge Face Memory Test: Results for neurologically intact individuals and an investigation of its validity using inverted face stimuli and prosopagnosic participants
Section snippets
Stimuli
The faces are those of men in their 20s and early 30s, and each individual was photographed in the same range of poses and lighting conditions. Men's faces were used, because men and women perform equivalently with men's faces whereas women show an advantage with women's faces (Lewin & Herlitz, 2002; McKelvie, 1987, McKelvie et al., 1993). All faces were cropped so that no hair was visible and facial blemishes were removed. The men posed with neutral expressions.
Six individuals were chosen as
Results
In this section, we discuss the results from our normal participants. Following this, we discuss two conditions aimed at determining whether our test effectively measures face recognition. We do this by first administering the test when all faces are presented inverted, and by giving the test in its upright version to prosopagnosic individuals.
Discussion
We created a new test of face memory in hopes that it can supplement standardized tests of face recognition. The results discussed in the previous section are very encouraging. Fig. 8 displays performance on the three sections of the test for the three conditions. First consider the upright percent correct. Because these scores are far off of the floor and the ceiling, the test can assess a wide range of abilities. Each of the top five possible scores (68–72) was achieved by only one
