基于經驗的整體加工理論認為，隨著知覺經驗的增多，人們加工面孔的專家化能力逐漸增強。其中一種表現形式為，在知覺面孔時更傾向于整體加工。該理論已經得到了一些實驗證據的支持，但未能解釋另外一些研究的發現，即對他族人群沒有長期知覺經驗的被試在加工他族面孔時也有強烈的整體加工。本研究旨在考察知覺經驗對面孔整體加工的影響，包括兩個實驗。實驗1a通過組合面孔范式測量了中國被試在辨別本族面孔、他族面孔和種族融合面孔時的組合面孔效應(即面孔整體加工強度)。結果發現，被試在知覺種族融合面孔時沒有表現出組合面孔效應，在知覺本族面孔和他族面孔時都表現出強烈的組合面孔效應。實驗1b以灰階圖重復了實驗1a。結果發現，被試在知覺種族融合面孔時仍然沒有表現出組合面孔效應，在知覺本族面孔和他族面孔時表現出強烈的組合面孔效應。實驗2通過操縱種族融合面孔的有或無，測量5 s的知覺經驗對融合面孔的組合效應的影響。結果發現，在經過短時的知覺經驗后，被試在知覺融合面孔時也表現出強烈的組合面孔效應。上述實驗結果表明，中國被試在加工本族面孔、他族面孔和種族融合面孔時所誘發組合面孔效應有顯著的、量的差別，且這種整體加工的差異不會受到面孔膚色信息的影響。在經過短時的知覺經驗后，中國被試在加工種族融合面孔時表現出強烈的整體加工。該研究的發現提示，不論是短時知覺經驗還是長期知覺經驗，知覺經驗的增加是面孔整體加工的一個關鍵要素。

It is well known that same-race faces are better discriminated and recognized than other-race faces, a phenomenon confirmed experimentally and termed in the literature for face perception as the "own-race advantage". Why do people have the bias in face processing? Some researchers claimed that the own-race advantage in discrimination is associated with interracial contact. The more visual experience with own race faces, the better discrimination within own-race faces. How visual experience affects the processing of same-race and other-race faces has yet to be determined. An influential hypothesis "experience-based holistic processing view" states that it would result from a reduced holistic processing with which we have less experience. To examine the effect of perceptual experience on holistic processing, with composite face paradigm and perceptual adaptation paradigm we investigated the composite-face effect of own-race faces, other-race faces and morphed faces during the perceptual discrimination. In the preliminary experiment, 20 Asian participants were presented with 704 color Asian-Caucasian morphed face stimuli for a race categorization task. These stimuli were generated with morphing software(MorphTM), allowing the creation of 11 blended face stimuli（from 0:100 to 100:0 for Asian:Caucasian proportions, respectively） for each of 64 Asian-Caucasian continua. In each continuum, the face that was equally often categorized as Asian and as Caucasian was identified as the ambiguous-race face. Result showed that the 52 Asian-Caucasian ambiguous faces were extracted and used as face stimuli in experiment 1a, experiment 1b and experiment 2. In Experiment 1a, we examined the holistic processing of own-race faces and other-race faces by using the composite paradigm in a two-alternative forced-choice delayed matching task. The results of Exp1 a showed that own-race faces and other-race faces are processed holistically. However, morphed faces are not processed holistically. With gray pictures as stimuli, Exp1 b replicated the same results as experiment 1a. In Experiment 2, we examined that the holistic processing of morphed faces can be induced by perceptual adaptation（5 seconds）. Results showed that the morphed faces were processed holistically after short-term perceptual adaptation. Collectively, these findings indicate that face holistic processing is modulated by perceptual experience, even the short-term perceptual adaptation may affect participants’ face holistic processing as one of the most important factors.
