Cambridge Face Memory Test Long Form
Chapter 5
Accuracy performance from the Cambridge Face Memory Test (first three
sections) and Cambridge Face Memory Test Long Form are shown in figure 5.3. No
significant differences were observed between synaesthetes and controls on either the
CFMT [F1,25 = .023, p = .880] (Figure 5.3a) or the CFMT + [F1,25 = .095, p = .761]
(Figure 5.3b). Therefore unlike facial expression recognition, synaesthetes and
controls did not differ in their ability to memorize facial identity.
Cambridge Face Perception Test
Error scores on the eight upright and eight inverted trials were summed to
determine the total number of upright and inverted errors. A 2 (Group) x 2 (Trial
Type) ANCOVA revealed a significant effect of trial type [F1,25 = 5.81, p = .024]
which was due to an inversion effect, whereby overall participants were less accurate
on inverted (mean ± s.e.m = 70 ± 3) compared with upright trials (mean ± s.e.m =
41.5 ± 3.21). Importantly, this effect did not interact with group [F1,25 = .37, p = .549]
and no main effect of group was found [F1,25 = .253, p = .619] (Figure 5.4).
Therefore, unlike expression recognition, synaesthetes and controls did not
significantly differ in their abilities to detect another’s facial identity.
