Multiple studies have shown a critical band of spatial frequencies (SF),
involving mostly low-spatial frequencies, in face identification. However,
it is unknown whether the use of this critical band is modulated by
individual differences in face identification. Thus, the aim of the present
study is to investigate whether inter-individual variation in face
identification, measured with the Cambridge Face Memory Test–Chinese
(CFMT-Chi), influences the use of SF information during an old-new face
recognition memory task. In the latter task, our participants recognised
unfiltered faces more accurately compared to spatial frequency filtered
faces, that were all equated for low-level visibility. Faces retaining only
low SF were recognised with comparable (above chance) accuracy to those
retaining only high SF. This suggests that both low and high SF information
are equally important for face recognition. Furthermore, scores in the
CFMT-Chi did not predict performances in all conditions. These findings
suggest that face recognition abilities do not modulate the critical band
of SF used for face recognition
