Adults' expert face recognition is limited to the kinds of faces they encounter on a daily basis (typically upright human faces of the same race). Adults process own-race faces holistically (Le., as a gestalt) and are exquisitely sensitive to small differences among faces in the spacing of features, the shape of individual features and the outline or contour of the face (Maurer, Le Grand, & Mondloch, 2002), however this expertise does not seem to extend to faces from other races. The goal of the current study was to investigate the extent to which the mechanisms that underlie expert face processing of own-race faces extend to other-race faces. Participants from rural Pennsylvania that had minimal exposure to other-race faces were tested on a battery of tasks. They were tested on a memory task, two measures of holistic processing (the composite task and the part/whole task), two measures of spatial and featural processing (the JanelLing task and the scrambledlblurred faces task) and a test of contour processing (JanelLing task) for both own-and other-race faces. No study to date has tested the same participants on all of these tasks. Participants had minimal experience with other-race faces; they had no Chinese family members, friends or had ever traveled to an Asian country. Results from the memory task did not reveal an other-race effect. In the present study, participants also demonstrated holistic processing of both own- and other-race faces on both the composite task and the part/whole task. These findings contradict previous findings that Caucasian adults process own-race faces more holistically than other-race faces. However participants did demonstrate an own-race advantage for processing the spacing among features, consistent with two recent studies that used different manipulations of spacing cues (Hayward et al. 2007; Rhodes et al. 2006). They also demonstrated an other-race effect for the processing of individual features for the Jane/Ling task (a direct measure of featural processing) consistent with previous findings (Rhodes, Hayward, & Winkler, 2006), but not for the scrambled faces task (an indirect measure offeatural processing). There was no own-race advantage for contour processing. Thus, these results lead to the conclusion that individuals may show less sensitivity to the appearance of individual features and the spacing among them in other-race faces, despite processing other-race faces holistically.

Classifying a race from a face image can provide a strong hint to search for facial identity and criminal identification. Current facial race classification methods are confined only to constrained non-partially occluded frontal faces. Challenges remain under unconstrained environments such as partial occlusions and pose variations, low illuminations, and small scales. In the second part of the dissertation, we propose a CNN model to classify facial races with partial occlusions and pose variations. The proposed model is trained using a broad and balanced racial distributed face image dataset. The model is trained on four major human races, Caucasian, Indian, Mongolian, and Negroid. Our model is evaluated against the state-of-the-art methods on a constrained face test dataset. Also, an evaluation of the proposed model and human performance is conducted and compared on our new unconstrained facial race benchmark (CIMN) dataset. Our results show that our model achieves 95.1% of race classification accuracy in the constrained environment. Furthermore, the model achieves a comparable accuracy of race classification compared to human performance on the current challenges in the unconstrained environment.

When you look at an angry or happy face, does it matter whose face you are looking at? In particular, does it matter what that person's race is? The experiments in the current study examined how we perceive emotional faces from different races. Eye-tracking experiments demonstrated that the race of a face profoundly affects how the face is scanned for clues about the person's emotional state. For White and Asian observers, (1) the eyes of White faces are scanned more than the eyes of Black and Asian faces, (2) the right hemi-face of White faces are scanned less than the right hemi-faces of Black and Asian faces, and (3) fixations to White faces are more random than fixations to Black or Asian faces. There were also differences in fixations to male and female faces; for example, more fixations were made to the eyes of female faces. These differences may be due to differences in structure and informativeness of the faces, and may affect the attribution of emotions. A chimeric face study (in which the right and left hemi-faces expressed different emotions) tested whether or not the race of an emotional face can moderate the strength of the left visual field bias. It was harder for observers to determine the relative emotional intensity of chimeric angry Black faces than angry White faces (i.e. response times were longer); there was no difference for happy faces. Response times for relative intensity judgments were also longer for male than female faces. Eye-tracking data were also recorded and indicated that there was also a stronger leftward fixation asymmetry for angry Black faces and happy White faces. In a visual search task, the response times to displays of angry faces increased as the number of Black faces increased, indicating a greater delay in disengagement from angry Black faces relative to angry White faces. On the other hand, response times to displays of happy faces decreased as the number of black face increased. The results are discussed in terms of perceived threat, racial stereotypes, and positive and negative evaluations of members of different races.

The other-race effect (ORE) in face recognition refers to poorer recognition of other- than own-race faces. This thesis addresses two overarching questions: what causes the ORE and what are the consequences of the ORE. Concerning the cause(s) of the ORE, two specific questions are addressed: whether social-motivation or perceptual experience (contact) contributes to the ORE; and whether plasticity of face recognition for face subtypes (specific races) is greater in childhood than in adulthood. My first empirical paper (Chapter 3) investigates the ORE for Caucasian and Asian participants (N=480) in an Australian setting where socio-economic status is similar between these groups. Using both the Cambridge Face Memory Task and an old-new recognition task, motivation-to-individuate instructions did not reduce the ORE for Caucasians and Eastern-raised Asians with low interracial contact. Further, Western-raised Asians with high interracial contact showed no ORE. Results imply the cause of the ORE, in this cultural setting, is lack of interracial contact rather than lack of social-motivation. A new dual-route approach is proposed in which two potential causes of the ORE - lack of social-motivation and lack of experience - can contribute differently across varying cultural settings. Another empirical paper (Chapter 5) asks whether the effects of interracial experience arise due to contact in childhood or adulthood, again testing Caucasian and Asian participants (N=373). Correlations with self-reported contact found larger OREs were significantly associated with lower contact during childhood, but not adulthood. That is, adulthood contact was ineffective for improving other-race face recognition. The same pattern is reported for smaller within-race variations in ethnicity. Findings imply that, similar to language, the developmental course of face recognition contains a "sensitive period" of greater plasticity during childhood. A third empirical paper (Chapter 4) addresses the apparent conflict that, in real life, the ORE can have serious consequences (e.g., cases of wrongful imprisonment based on eyewitness misidentification), yet, laboratory studies show only a modest-sized mean ORE. This chapter, using an individual differences approach, investigates whether there exists a subgroup of individuals who are so poor at recognising other-race faces they are 'face blind' for other-race faces. Results indicated 8.1% of Caucasian and Eastern-raised Asian individuals (N=444) were other-race face blind. Risk factors included: being at low end of the normal range of own-race face recognition ability; and lack of interracial contact (particularly in childhood); but not lack of effort applied to individuating other-race faces. Taken together, my findings have broad theoretical and practical implications. Theoretically, results argue the cause of the ORE, at least for Caucasians and Asians in an Australian setting, is lack of perceptual experience in childhood, and not lack of social-motivation to individuate other-race people. Practically, the results argue: overcoming the ORE via real-world contact requires specifically childhood experience; simply increasing motivation is ineffective for improving other-race face recognition; and while some individuals will suffer no real-word functional consequences of the ORE, others, with other-race face blindness, would be expected to suffer severe functional problems in everyday life (e.g., failures to recognise other-race colleagues in the workplace).

Same-race faces are better discriminated and recognized than less experienced, other-races faces. This "Own-Race Bias" (ORB) has been robustly demonstrated in many psychological studies, yet the perceptual basis of this phenomenon is still not well understood. Recent face perception studies have discovered that configural properties of the face (i.e., the spatial relations among features) are processed differently than featural information, and may be directly tied to developmental experience with faces. This study examines age-related changes in the ORB and seeks to determine whether a superior developmental improvement in the perception of configural information in more experienced same-race faces contributes to the emergence of the ORB. A sample of children and adults with high-functioning autism were also included to test whether these processes differ for this population. The book is addressed to researchers interested in development, face perception, and autism.
