Spatial frequency tuning of upright and inverted face identification.

摘要: Abstract Previous research suggests that observers use information near the eyes and eyebrows to identify both upright inverted faces [Sekuler, A. B., Gaspar, C. M., Gold, J. & Bennett, P. (2004). Inversion leads quantitative, not qualitative, changes in face processing. Current Biology, 14 (5), 391–396]. Here we ask whether more significant differences between processing exist spatial frequency domain. Thresholds were measured a 1-of-10 identification task with presented no noise, white Gaussian low-pass high-pass filtered noises various cutoff frequencies. In Experiment 1, all fronto-parallel view; 2, viewpoint varied across trials. higher for faces, but magnitude of inversion effect did vary conditions or experiments. Moreover, shapes noise-masking functions obtained noise same experiments, revealed was based on carried by 1.5 octave wide band frequencies centered approximately 7 cycles per width. Finally, individual related selectivity identification. The results indicate judgments is due subjects using different bands faces.
