(2018): Multicultural Facial Expression Recognition Based on Differences of Western-Caucasian and East-Asian Facial Expressions of Emotions. In: IEICE Transactions on Information and Systems 101 (5), S. 1317-1324. DOI: 10.1587/transinf.2017MVP0025
Abstract: An increasing number of psychological studies have demonstrated that the six basic expressions of emotions are not culturally universal. However, automatic facial expression recognition (FER) systems disregard these findings and assume that facial expressions are universally expressed and recognized across different cultures. Therefore, this paper presents an analysis of Western-Caucasian and East-Asian facial expressions of emotions based on visual representations and cross-cultural FER. The visual analysis builds on the Eigenfaces method, and the cross-cultural FER combines appearance and geometric features by extracting Local Fourier Coefficients (LFC) and Facial Fourier Descriptors (FFD) respectively. Furthermore, two possible solutions for FER under multicultural environments are proposed. These are based on an early race detection, and independent models for culture-specific facial expressions found by the analysis evaluation. HSV color quantization combined with LFC and FFD compose the feature extraction for race detection, whereas culture-independent models of anger, disgust and fear are analyzed for the second solution. All tests were performed using Support Vector Machines (SVM) for classification and evaluated using five standard databases. Experimental results show that both solutions overcome the accuracy of FER systems under multicultural environments. However, the approach which individually considers the culture-specific facial expressions achieved the highest recognition rate.

(2014): Art as behaviour – an ethological approach to visual and verbal art, music and architecture. In: Anthropologischer Anzeiger 71 (1), S. 3-13. DOI: 10.1127/0003-5548/2014/0371
Abstract: In recent years, the fine arts, architecture, music and literature have increasingly been examined from the vantage point of human ethology and evolutionary psychology. In 2011 the authors formed the research group 'Ethology of the Arts' concentrating on the evolution and biology of perception and behaviour. These novel approaches aim at a better understanding of the various facets represented by the arts by taking into focus possible phylogenetic adaptations, which have shaped the artistic capacities of our ancestors. Rather than culture specificity, which is stressed e.g. by cultural anthropology and numerous other disciplines, universal human tendencies to perceive, feel, think and behave are postulated. Artistic expressive behaviour is understood as an integral part of the human condition, whether expressed in ritual, visual, verbal or musical art. The Ethology of the Arts-group's research focuses on visual and verbal art, music and built environment/architecture and is designed to contribute to the incipient interdisciplinarity in the field of evolutionary art research.

(2013): On the cultural character of metaphor. Some reflections on Universality and Culture-specificity in the language and cognition of time, especially in Amerindian languages. In: REVIEW OF COGNITIVE LINGUISTICS 11 (1), S. 1-35. DOI: 10.1075/rcl.11.1.01ber
Abstract: The paper is devoted to an analysis of the relation between language and culture in the context of Conceptual Metaphor Theory (CMT). Section 2 deals in an explicitly critical way with some problems in the concept of "culture" as used in "mainstream" schools of CL. Section 3 offers a brief review of the problems involved in the studies on the concept of "time" and its metaphors. Section 4 reviews some interpretations of the concept of "time" in Amerindian cultures. Section 5 analyses the linguistic expression of time in Quechua, in an attempt to (dis)confirm the "past in front" conceptualisation proposed by some researchers for the (geographically and culturally close, but genetically unrelated) Aymara language. Some final conclusions follow.

(2013): Universal belief-desire psychology?. A dilemma for theory theory and simulation theory. In: Philosophical Psychology 26 (5), S. 744-764. DOI: 10.1080/09515089.2012.711034
Abstract: In this article we take issue with theory theory and simulation theory accounts of folk psychology committed to (i) the belief-desire (BD) model and (ii) the assumption of universality (AU). Recent studies cast doubt on the compatibility of these commitments because they reveal considerable cross-cultural differences in folk psychologies. We present both theory theory and simulation theory with the following dilemma: either (i) keep the BD-model as an account of the surface properties of specific explicit folk psychologies and give up AU in light of the cross-cultural evidence; or (ii) defend AU with respect to core capacities underlying different culture-specific folk psychologies, and explain why the BD-model will be genuinely explanatory at this level.

(2001): Cultural variation in hemifacial asymmetry of emotion expressions. In: British Journal of Social Psychology 40 (3), S. 385-398. DOI: 10.1348/014466601164885
Abstract: Photographs of hemifacial composites (left-left, right-right and normal presentation, right-left) of three cultures (Japanese, Oriental Indian and North American) disp laying six emotions (happy, sad, fear, anger, surprise, disgust) and a neutral state were administered successively (one by one) as well as simultaneously (three hemifacial photographs of an expression at a time) to observers for judgment on a 5-point scale in terms of distinctiveness of expression. Observers' judgments were treated with a culture of expressor x sex of expressor x facial presentation x emotion category mixed factorial ANOVA. Cultures did not vary for their distinctiveness of facial expressions, suggesting universality in this respect. Culture-specificity was, however, observed with respect to hemifacial asymmetry and valence of emotion expressions: (1) Japanese showed a right hemifacial bias for positive and left hemifacial bias for negative emotions; Indians and North Americans showed left hemifacial bias for all emotions, and (2) negative emotion expressions were least distinctly identifiable in Japanese faces followed by Indian and North American faces.

(2000): The concept of anger. Universal or culture specific?. In: Psychopathology 33 (4), S. 159-170. DOI: 10.1159/000029139
DOI: http://www.ncbi.nlm.nih.gov/pubmed/10867573 Abstract: I will suggest that the English word 'anger' and its counterparts in diverse languages of the world are based on concepts of anger that have a great deal of complexity. This conceptual complexity derives from several sources: (1) the metaphors and metonymies that apply to the concepts in various languages; (2) the prototypes of anger that people share in these cultures, and (3) the many different senses that the word anger and its counterparts have in different languages. We can ask: Are there any universal aspects of the concept(s) of anger? On the basis of linguistic evidence from English, Chinese, Japanese, Hungarian, Zulu and Wolof, I will suggest that there are, but I will also claim that some of the aspects are culture specific. This raises the further important question of why there is both universality and culture specificity in the conceptualization of this emotion. At stake is the issue of which of the following two contradictory claims is valid: (1) that anger is conceptualized in the same way universally, or (2) that anger is a social construction and thus varies considerably from culture to culture. I will propose a compromise view, which can be called 'body-based social constructionism', that enables us to see anger and its counterparts as both universal and culture specific.
