has shown that social perception of wealth has the ability to modulate the effect: when the targets were seen as impoverished, the difference in facial recognition disappeared. Integration of cross-race effect theories Prototypes Individuals develop and store a face prototype each time they encounter a face unique to ones he or she has previously encountered (usually ones that differ in features compared to his or her ethnic group). From their studies, researchers have concluded that when an individual belonging to an ethnicity that differs from his or her own, he or she forms a prototype and reserves it for future use, if and when necessary. The prototype view raises concern, however, because individuals storing these unique faces may ignore the fact that everyone has features that may be only special to his or her makeup, and may not apply to everyone belonging to that particular ethnic group or race; thus, this results in more false alarms during eyewitness testimony or identifying perpetrators in lineups. Race-feature theory Deeper study of the cross-race effect has demonstrated two types of processing for the recognition of faces: featural and holistic. It has been found that holistic processing (which occurs beyond individual parts of the face) is more commonly used in same-race situations, but there is an experience effect, which means that as a person gains more experience with those of a particular race, he or she will begin to use more holistic processing. Featural processing is much more commonly used with an unfamiliar stimulus or face. In his 1996 study, researchers noticed that when looking at ethnicity, in-group faces are processed without acknowledgement of ethnic-specific details and features. People code faces that deviate from the norm of their ethnic group through the absence or presence of distinctive ethnic features. This is supported by the finding that the classification of other-race faces tends to be faster than same-race faces. This suggests that race seems to be a more perceptually salient feature than other more discerning facial features when the face belongs to a different race. Some eye tracking studies found tentative evidence for such a hypothesis by demonstrating that people look at different facial features in same- versus other-race faces. The general trend observed is that people fixate the eyes of a face with higher probability if it belongs to the same ethnic group as the observer her- or himself. Other studies found stable differences
