Running head: THE YIN AND YANG OF CULTURAL NEUROSCIENCE The Yin and Yang of Cultural Neuroscience in Design Lisa D. Harper University of Baltimore IDIA 640 1 THE YIN AND YANG OF CULTURAL NEUROSCIENCE Abstract Culture is not innate but learned. It defines the boundaries between groups of people and touches every aspect of life. Language and social communication are innate, yet influenced by culture. This paper focuses on the role of culture in shaping cognitive and neurological processes: particularly, as concern differences between Westerners and East Asians. Two wellknown cultural models used in cross-cultural design studies are examined. Both are seen to be useful, but incomplete. Of greater explanatory and predictive power is a recently proposed theoretical framework that accounts for cultural differences and similarities in brain and behavioral responses. 2 THE YIN AND YANG OF CULTURAL NEUROSCIENCE 3 The Yin and Yang of Cultural Neuroscience in Design As of June 30, 2010, more than 70% percent of internet users are native speakers of some language other than English (Internet World Stats, 2010). Nearly 30% of those users are from East Asia (China, Japan, and Korea). Not surprisingly, website designers are increasingly concerned with cross-cultural audiences. This is largely due to globalization and international market forces. Web site designers and usability professionals have, in recent years, begun to explore the idea of culture-centered design. It is very clear that websites from other countries or cultures vary. There are often differences in terms of color, style, use of media, layout, menus, and so on. Designers hypothesize that some of these differences may be systematic and endemic to particular cultures. In the past, localization for international audiences concerned adaptation (e.g., translation) of web sites for foreign speakers. Today, a more sophisticated understanding of culture drives designers to better understand how foreign audiences may engage and interact with online content. The next section discusses two prominent cultural models used in crosscultural design analyses. Following, recent findings in cognitive psychology and neuroscience are discussed. Finally, design implications are raised. Cross-cultural design is a rich area of investigation of global consequence, but it’s a discipline still in its infancy. Cultural Models In 1971, cultural anthropologist Edward T. Hall published an influential book, “Beyond Culture,” in which he discusses the effect of culture on communication. "Intelligence is ... paying attention to the right things. The linear quality of a language inevitably results in accentuating some things at the expense of others" (Hall, 1971, p. 87). He suggests that selective attention is not limited to visual perception or linguistic phenomenon, but is characteristic of THE YIN AND YANG OF CULTURAL NEUROSCIENCE 4 culture, as well. In Hall’s model, some information is conveyed in the message and some in the context (situational or cultural). In high-context (HC) message, most of the information is either in external or internal (mental) context, while very little is in the coded, linguistic part of the message. By contrast, a low context (LC) communication encodes information more explicitly in the message. Western cultures are considered relatively LC communicators, while Asian cultures are considered relatively HC communicators. Hall goes on to describe properties of LC cultures and HC cultures. For instance, in HC cultures, the sense of shared community and interdependence is strong while in LC cultures, people tend to be more individualistic with a stronger sense of personal agency. Social scientist, Geert Hofstede approached the study of culture quite differently. He defined culture in terms of explicitly held beliefs and values. As such, he used survey questions to get at cultural values and attitudes. Based on surveys from 57 countries in which IBM had employees, he defined five dimensions of culture relating to national work value propositions: perception of small (e.g., democratic) versus large (e.g., autocratic) power distances; individualism versus collectivism; masculinity versus femininity; weak versus strong uncertainty avoidance; long versus short term orientation (Hofstede, 2001). Importantly, these cultural differences describe averages or tendencies and not characteristics of individuals. Hofstede argued that people embody "mental programs" developed in the family and reinforced in schools and organizations (Hofstede, 2001). These programs contain components of national culture. Though, Hofstede and Hall may have shared many observations in common, they developed very different models and methods – as one might expect from researchers working across different disciplines (Cardon, 2008). Cross-Cultural Design THE YIN AND YANG OF CULTURAL NEUROSCIENCE 5 Marcus and Gould (2000) published an influential work in Interactions suggesting cultural models be used to study cross-cultural digital design. Looking at Hofstede's five dimensions, the authors examined a number of university websites from countries studied in Hofstede's original analysis. This spurned a rash of activity in design analysis. In 2005, Würtz produced an exploratory cross-cultural analysis (using elements of both Hall and Hofstede) of various localizations of the McDonald’s website. She hypothesized that people in “high context cultures” are more likely to adopt visual effects to convey their messages than people from “low context cultures”. She believed the study provided support for her hypothesis, but was careful not to draw too many conclusions from her study. Soon after, other studies were published. Usinier & Roulin (2001), Cyr & Trevor-Smith (2004), Callahan (2005), Kralisch, Berendt & Eisend (2005), Stengers, Baetens, Boers & Troyer (2005) all produced studies using either models from Hofstede, Hall, or a combination. Each study produced a number of hypotheses (e.g., “the pages making up LC websites are expected to be consistent in their layout and color schemes, whereas pages in HC websites are expected to be diverse”; “the relative frequency of images of [university] faculty is correlated positively with country scores on the [Hofstede] power distance dimension”). Each hypothesis linked to either HC / LC or a Hofstede dimension. Results were primarily analyzed in terms human-annotated coding of website features1. Stengers et al. (2005) was the only study to not validate proposed hypotheses. Through a follow-up survey to web masters from the sites they studied, they found that respondents indicated “substantial receptivity to external influences toward periodic redesigns” (p. 30). 1 Kralisch, Berendt, and Eisend (2005) actually looked at server logs to determine user navigation behavior. Otherwise, they followed the same basic research method as the other authors. THE YIN AND YANG OF CULTURAL NEUROSCIENCE 6 There is a significant problem with the method followed above. None of the studies above addressed the issue of whether an LC annotator can make a fair judgment of foreign cultural values and beliefs based on observable characteristics of website design. More to the point, it is not possible to test such broadly defined hypotheses while factoring out other variables. Not surprisingly, most of the hypotheses were “validated,” adding to the wealth of pseudo-support generated by related such studies. This is not to say that the observations, or even conclusions, about cross-cultural design were invalid. The point is that such studies do not follow the scientific method and cannot be considered empirical evidence in support of the underlying models. Context in cognition Dong and Lee (2008) carried out a focused design study by looking at how Chinese, Korean, and American participants viewed webpages. They performed an eye-tracking study following cognitive psychological literature of Nisbett (2001). They saw different viewing patterns between East Asian and American subjects on a news page with a 9x9 grid layout. East Asians tended to scan the whole page the while Westerners read from center to periphery of the page. Recent work in cognitive psychology has provided a very compelling argument for contrasting the analytic thinking of Westerners to holistic thinking of those from the Far East. In general, analytic thinking patterns are contrasted with holistic thinking in the following manner (Nisbett, 2001): Analytic Holistic "Individualistic" or "independent" "Collectivist" or "interdependent" Rhetoric and debate Harmonious relations THE YIN AND YANG OF CULTURAL NEUROSCIENCE Atomic and logical 7 Contextual and dialectic Through careful experimentation, cognitive psychologists find cultural influences affecting: Perception and attention – East Asians seem to be more sensitive to contextual changes than to focal object changes. They attend to the field in which a salient object is located. This has been validated in numerous studies including those that consider effects in change-blindness (Masuda & Nisbett, 2006) and social versus non-social focal objects (Masuda & Nisbett, 2001). Categorization and reasoning – East Asians tend to categorize objects on the basis of relationships versus taxonomic “rules” (Nisbett & Masuda, 2003). For example, a cow may be categorized with grass versus a pig, since cows eat grass. They also look for dialectical schemas in making judgments about the behavior of objects and individuals (Nisbett & Masuda, 2003). Cultural Neuroscience There is new evidence supporting the notion that cultural values and experiences affect and shape neurocognitive processes (Hedden, Ketay, Aron, Markus, Gabrieli, 2008; Chaio 2010). Culture influences patterns of selective attention and may even shape neural structure (Park and Huang, 2010). Brain imaging studies confirm and are in agreement with cognitive studies and the analytic/holistic dichotomy of mind (Goh et al., 2007; Goh & Park, 2009). Indeed, culture may influence brain patterns even in terms of memory, emotion, and reasoning (Gutchess & Indek, 2009). Kitayama and Park (2010) propose a theoretical framework for understanding culturemind interaction. They distinguish between three components, or layers, of culture. THE YIN AND YANG OF CULTURAL NEUROSCIENCE 8 1. Explicit shared values 2. “Cultural tasks” (conventions, routines and shared scripts for action) which are intended to achieve culture’s primary values (e.g., equality) 3. Implicit psychological and neural tendencies that align with the culture’s values. These tendencies align because underlying neural activities are culturally patterned and reinforced. This framework effectively accounts for observations from the social sciences but with much more explanatory and predictive power. Implications for Cross-Cultural Design Schmid-Isler (2000) made the comment that Chinese homepages tend to divide the screen into many independently focused spaces. In contrast, “western style prefers a focused layout, with a picture as the visual attractor and center” (p. 4; fig 1 below). This seems to be in accordance with Dong and Lee’s assessment of cognitive reading style. Figure 1. Nanjing (jlonline.com) and New York Times homepages (Isler-Schmid, 2000) THE YIN AND YANG OF CULTURAL NEUROSCIENCE 9 Figure 2. New York Times circa Nov 2010 Yet in 2010, views of the NYT homepage show a dramatic shift (fig 2). The same American site contains many more spaces. Clearly, other factors are at play. Culture is complex and we have much yet to learn. Based on research presented above, when evaluating a design for a multi-cultural (particularly, East Asian) website, it's important to take into account: The relative importance and role of context (e.g., image content and framing) The manner in which people of different cultures read (e.g., layout) Semantic categorization (e.g., menus and content categories); and, Cultural values, as expressed in many ways THE YIN AND YANG OF CULTURAL NEUROSCIENCE 10 Webpage design should be carried out according to the target audience's specific cognitive style to the extent possible.
