What is "special" about face perception?

What is "special" about face perception?
by Farah, Martha J.; Wilson, Kevin D.; Drain, Maxwell; Tanaka, James N.
from Psychological Review. 1998 Jul Vol 105(3) 482-498

There is growing evidence that face recognition is "special" but less certainty concerning the way in which it is special. The authors review and compare previous proposals and their own more recent hypothesis, that faces are recognized "holistically" (i.e., using relatively less part decomposition than other types of objects). This hypothesis, which can account for a variety of data from experiments on face memory, was tested with 4 new experiments on face perception. A selective attention paradigm and a masking paradigm were used to compare the perception of faces with the perception of inverted faces, words, and houses. Evidence was found of relatively less part-based shape representation for faces. The literatures on machine vision and single unit recording in monkey temporal cortex are also reviewed for converging evidence on face representation. The neuropsychological literature is reviewed for evidence on the question of whether face representation differs in degree or kind from the representation of other types of objects.

Here we look for crowding in faces and words as a symptom of recognition by parts. Crowding describes the impairment of recognizability of a target object by neighboring objects.

Critical spacing is how far away (center to center) each flanker must be to allow recognition of the target. When spacing is smaller than critical, the presence of the flankers makes recognition of the target harder or impossible. Beyond the critical spacing, recognition is unimpaired, and additional spacing provides no further benefit.

Proportional dependence of critical spacing on eccentricity, independent of signal size, is diagnostic of crowding; the converse (proportional dependence on size, independent of eccentricity) indicates ordinary masking (Pelli, Palomares, & Majaj, 2004).

Earlier authors have used various other names for a region over which features are integrated: “integration field,” “perceptive field,” “perceptive hypercolumn,” “spatial interference zone,” “region of selection,” and “association field” (Levi, Klein, & Aitsebaomo, 1985; Toet & Levi, 1992; Latham & Whitaker, 1996; Intriligator & Cavanagh, 2001; Field, Hayes, & Hess, 1993).

Contour interpolation revealed by a dot localization paradigm.

Guttman SE, Kellman PJ.

Contour interpolation mechanisms allow perception of bounded objects despite incomplete edge information. Here, we introduce a paradigm that maps interpolated contours as they unfold over time. Observers localize dots relative to perceived boundaries of illusory, partly occluded, or control stimuli. Variations in performance with dot position and processing time reveal the location and precision of emerging contour representations. Illusory and occluded contours yielded more proficient dot localization than control stimuli containing only spatial cues, suggesting performance based on low-level representations. Further, illusory contours exhibited a distinct developmental time course, emerging over the first 120 ms of processing. These experiments establish the effectiveness of the dot localization paradigm for examining interpolated edge representations, contour microgenesis, and the underlying processing mechanisms.

脳死と尊厳死の問題から、論点はずいぶんとずれてしまった。夫、家族の問題はまだしも、大統領の介入やその背後の宗教的勢力の圧力まで、アメリカの保守層の政治的力を見せつけられた思いだ。
