We report detailed investigations of the face processing abilities of four patients who had shown symptoms involving delusional misidentification. One (GC) was diagnosed as a Frégoli case, and the other three (SL, GS, and JS) by symptoms of intermetamorphosis. The face processing tasks examined their ability to recognize emotional facial expressions, identify familiar faces, match photographs of unfamiliar faces, and remember photographs of faces of unfamiliar people. The Frégoli patient (GC) was impaired at identifying familiar faces, and severely impaired at matching photographs of unfamiliar people wearing different disguises to undisguised views. Two of the intermetamorphosis patients (SL and GS) also showed impaired face processing abilities, but the third US) performed all tests at a normal level. These findings constrain conceptions of the relation between delusional misidentification, face processing impairment, and brain injury.

Investigations of two cases of the Capgras delusion found that both patients showed face-processing impairments encompassing identification of familiar faces, recognition of emotional facial expressions, and matching of unfamiliar faces. In neither case was there any impairment of recognition memory for words. These findings are consistent with the idea that the basis of the Capgras delusion lies in damage to neuro-anatomical pathways responsible for appropriate emotional reactions to familiar visual stimuli. The delusion would then represent the patient's attempt to make sense of the fact that these visual stimuli no longer have appropriate affective significance.

Face Expressions

Future thinking, which is the ability to project oneself forward in time to pre-experience an event, is intimately associated with emotions. We investigated whether emotional future thinking can activate emotional facial expressions. We invited 43 participants to imagine future scenarios, cued by the words “happy,” “sad,” and “city.” Future thinking was video recorded and analysed with a facial analysis software to classify whether facial expressions (i.e., happy, sad, angry, surprised, scared, disgusted, and neutral facial expression) of participants were neutral or emotional. Analysis demonstrated higher levels of happy facial expressions during future thinking cued by the word “happy” than “sad” or “city.” In contrast, higher levels of sad facial expressions were observed during future thinking cued by the word “sad” than “happy” or “city.” Higher levels of neutral facial expressions were observed during future thinking cued by the word “city” than “happy” or “sad.” In the three conditions, the neutral facial expressions were high compared with happy and sad facial expressions. Together, emotional future thinking, at least for future scenarios cued by “happy” and “sad,” seems to trigger the corresponding facial expression. Our study provides an original physiological window into the subjective emotional experience during future thinking.

One of the most impressive disorders following brain damage to the ventral occipitotemporal cortex is prosopagnosia, or the inability to recognize faces. Although acquired prosopagnosia with preserved general visual and memory functions is rare, several cases have been described in the neuropsychological literature and studied at the functional and neural level over the last decades. Here we tested a brain-damaged patient (PS) presenting a deficit restricted to the category of faces to clarify the nature of the missing and preserved components of the face processing system when it is selectively damaged. Following learning to identify 10 neutral and happy faces through extensive training, we investigated patient PS's recognition of faces using Bubbles, a response classification technique that sampled facial information across the faces in different bandwidths of spatial frequencies [Gosselin, F., & Schyns, P. E., Bubbles: A technique to reveal the use of information in recognition tasks. Vision Research, 41, 2261-2271, 2001]. Although PS gradually used less information (i.e., the number of bubbles) to identify faces over testing, the total information required was much larger than for normal controls and decreased less steeply with practice. Most importantly, the facial information used to identify individual faces differed between PS and controls. Specifically, in marked contrast to controls, PS did not use the optimal eye information to identify familiar faces, but instead the lower part of the face, including the mouth and the external contours, as normal observers typically do when processing unfamiliar faces. Together, the findings reported here suggest that damage to the face processing system is characterized by an inability to use the information that is optimal to judge identity, focusing instead on suboptimal information.

Expression Processing

Recognition of affect expressed in the face is disrupted when the body expresses an incongruent affect. Existing research has documented such interference for universally recognizable bodily expressions. However, it remains unknown whether learned, conventional gestures can interfere with facial expression processing. Study 1 participants (N = 62) viewed videos of facial expressions accompanied by hand gestures and reported the valence of either the face or hand. Responses were slower and less accurate when the face-hand pairing was incongruent compared to congruent. We hypothesized that hand gestures might exert an even stronger influence on facial expression processing when other routes to understanding the meaning of a facial expression, such as with sensorimotor simulation, are disrupted. Participants in Study 2 (N = 127) completed the same task, but the facial mobility of some participants was restricted, which disrupted face processing in prior work. The hand-face congruency effect from Study 1 was replicated. The facial mobility manipulation affected males only, and it did not moderate the congruency effect. The present work suggests the affective meaning of conventional gestures is processed automatically and can interfere with face perception, but perceivers do not seem to rely more on gestures when sensorimotor face processing is disrupted.

Ethical Requirement

Levinasian philosophy is characterized as a philosophy of ethical subjectivity and asymmetrical responsibility. Ethics is understood as the subject that gives itself entirely to the Other. However, the Other is never alone. His face attests to the presence of a third party who, looking at me in his eyes, cries for justice. There is no longer any question for the subject to devote himself entirely to the Other (ethical justice), to give everything to him at the risk of appearing empty-handed before the third party. How then to serve both the Other and the third party? The question of the political appears in the thought of Levinas with the emergence of the third party who, like the Other, challenges me and commands me (social justice). The third party establishes a political space. Politics is in the final analysis the place of the universalization of the ethical requirement born from face-to-face with the face of the Other.

Facial Trustworthiness

Face processing has mainly been investigated by presenting facial expressions without any contextual information. However, in everyday interactions with others, the sight of a face is often accompanied by contextual cues that are processed either visually or under different sensory modalities. Here, we tested whether the perceived trustworthiness of a face is influenced by the auditory context in which that face is embedded. In Experiment 1, participants evaluated trustworthiness from faces that were surrounded by either threatening or non-threatening auditory contexts. Results showed that faces were judged more untrustworthy when accompanied by threatening auditory information. Experiment 2 replicated the effect in a design that disentangled the effects of threatening contexts from negative contexts in general. Thus, perceiving facial trustworthiness involves a cross-modal integration of the face and the level of threat posed by the surrounding context.

The Third Reich

The Kingdom of the Serbs, Croats and Slovenes inherited a considerable number of Germans along with its ex-Habsburg territories when it was established in December 1918. The two most important German communities in inter-war Yugoslavia were the Germans of Slovenia and the Germans of the Vojvodina and Croatia-Slavonia, the so-called Donau Schwaben (Swabians). There were also scattered pockets of ethnic Germans in Bosnia-Hercegovina. The Yugoslavian ethnic Germans (Volksdeutsche), like the other Yugoslavian non-Slav minorities, were objects of discrimination by the Yugoslavian government. The Slovenian German community responded to this hostility by developing a virulent German nationalism which, after 1933, rapidly turned into Nazism. The Swabian community, on the other hand, generally tried to cooperate with the central government in Belgrade. The Swabians remained rather ambivalent toward the rising Nazi movement until the tremendous successes of the Third Reich in 1938 made Nazism irresistibly attractive. In the face of the government's anti-German policies, why did each of these German communities manifest such different attitudes towards the Yugoslav state during the inter-war period? This article will show how several factors of history, demography, and geography combined to produce the different reactions of the two groups.
