Culturally non-preferred cognitive tasks require compensatory attention: A functional near infrared spectroscopy (fNIRS)investigation
(2015-01-01) Murata, Asuka; Park, Jiyoung; Kovelman, Ioulia; Hu, Xiaosu; Kitayama, Shinobu
Previous work shows that as compared to European Americans, Asians are more holistic (or less focused) in perceptual processing. Drawing on this evidence, we expected that extra attention control would be recruited to perform focused processing for Asians and holistic processing for European Americans. Eight Asian American and 13 European American young adults judged whether a given framed-line was the same in length as the framed-line shown on the previous trial on the basis of either an absolute or relative criterion. Their brain activities were monitored with functional near infrared spectroscopy. As predicted, Asian Americans showed an increased activation in the parietal regions during the absolute (vs. relative) task, whereas European Americans showed an increased activation in the same regions during the relative (vs. absolute) task. No comparable pattern was observed for performance. The current work provides further evidence for compensatory attention that is engaged during culturally non-preferred tasks.
Self-talk as a regulatory mechanism: How you do it matters

Does the language people use to refer to the self during introspection influence how they think, feel, and behave under social stress? If so, do these effects extend to socially anxious people who are particularly vulnerable to such stress? Seven studies explored these questions (total N = 585). Studies 1a and 1b were proof-of-principle studies. They demonstrated that using non-first-person pronouns and one's own name (rather than first-person pronouns) during introspection enhances self-distancing. Studies 2 and 3 examined the implications of these different types of self-talk for regulating stress surrounding making good first impressions (Study 2) and public speaking (Study 3). Compared with the first-person group, the non-first-person group performed better according to objective raters in both studies. They also displayed less distress (Studies 2 and 3) and engaged in less maladaptive postevent processing (Study 3). Studies 4 and 5 examined how these different forms of self-talk influence the way people appraise social-anxiety-provoking events. They demonstrated that non-first-person language use (compared with first-person language use) leads people to appraise future stressors in more challenging and less threatening terms. Finally, a meta-analysis (Study 6) indicated that none of these findings were moderated by trait social anxiety, highlighting their translational potential. Together, these findings demonstrate that small shifts in the language people use to refer to the self during introspection consequentially influence their ability to regulate their thoughts, feelings, and behavior under social stress, even for vulnerable individuals.
Expression of anger and ill health in two cultures: an examination of inflammation and cardiovascular risk
(2015-01-01) Kitayama, Shinobu; Park, Jiyoung; Boylan, Jennifer Morozink; Miyamoto, Yuri; Levine, Cynthia S.; Markus, Hazel Rose; Karasawa, Mayumi; Coe, Christopher L.; Kawakami, Norito; Love, Gayle D.; Ryff, Carol D.
Expression of anger is associated with biological health risk (BHR) in Western cultures. However, recent evidence documenting culturally divergent functions of the expression of anger suggests that its link with BHR may be moderated by culture. To test this prediction, we examined large probability samples of both Japanese and Americans using multiple measures of BHR, including pro-inflammatory markers (interleukin-6 and C-reactive protein) and indices of cardiovascular malfunction (systolic blood pressure and ratio of total to HDL cholesterol). We found that the link between greater expression of anger and increased BHR was robust for Americans. As predicted, however, this association was diametrically reversed for Japanese, among whom greater expression of anger predicted reduced BHR. These patterns were unique to the expressive facet of anger and remained after we controlled for age, gender, health status, health behaviors, social status, and reported experience of negative emotions. Implications for sociocultural modulation of bio-physiological responses are discussed.
Cultural neuroscience of the self: understanding the social grounding of the brain
(2010-01-01) Kitayama, Shinobu; Park, Jiyoung
Cultural neuroscience is an interdisciplinary field of research that investigates interrelations among culture, mind and the brain. Drawing on both the growing body of scientific evidence on cultural variation in psychological processes and the recent development of social and cognitive neuroscience, this emerging field of research aspires to understand how culture as an amalgam of values, meanings, conventions, and artifacts that constitute daily social realities might interact with the mind and its underlying brain pathways of each individual member of the culture. In this article, following a brief review of studies that demonstrate the surprising degree to which brain processes are malleably shaped by cultural tools and practices, the authors discuss cultural variation in brain processes involved in self-representations, cognition, emotion and motivation. They then propose (i) that primary values of culture such as independence and interdependence are reflected in the compositions of cultural tasks (i.e. daily routines designed to accomplish the cultural values) and further (ii) that active and sustained engagement in these tasks yields culturally patterned neural activities of the brain, thereby laying the ground for the embodied construction of the self and identity. Implications for research on culture and the brain are discussed.
Subjective and objective hierarchies and their relations to psychological well-being: A U.S./Japan comparison
(2014-01-01) Curhan, Katherine B.; Levine, Cynthia S.; Markus, Hazel Rose; Park, Jiyoung; Karasawa, Mayumi; Love, Gayle D.; Coe, Christopher L.; Miyamoto, Yuri; Ryff, Carol D.
Hierarchy can be conceptualized as objective social status (e.g., education level) or subjective social status (i.e., one's own judgment of one's status). Both forms predict well-being. This is the first investigation of the relative strength of these hierarchy-well-being relationships in the U.S. and Japan, cultural contexts with different normative ideas about how social status is understood and conferred. In probability samples of Japanese (N=1027) and U.S. (N=1805) adults, subjective social status more strongly predicted life satisfaction, positive affect, sense of purpose, and self acceptance in the U.S. than in Japan. In contrast, objective social status more strongly predicted life satisfaction, positive relations with others, and self acceptance in Japan than in the U.S. These differences reflect divergent cultural models of self. The emphasis on independence characteristic of the U.S. affords credence to one's own judgment (subjective status) and the interdependence characteristic of Japan to what others can observe (objective status).
Cultural variation in implicit independence: An extension of Kitayama et al.
(2015-01-01) Park, Jiyoung; Uchida, Yukiko; Kitayama, Shinobu
Previous research shows that European Americans are consistently more independent (or less interdependent) than Japanese when implicit indices are used to assess independence (vs. interdependence). The present work extended this evidence by including a novel implicit association test (IAT), as an index of implicit attitude towards independence and interdependence. Consistent with the previous findings, as compared to Japanese, Americans were significantly higher in multiple indices of implicit independence (vs. interdependence) including personal (vs. social) self-definition, experience of disengaging (vs. engaging) emotions and personal (vs. social) form of happiness. Furthermore, as compared to Japanese, Americans had a significantly more positive implicit attitude towards independence assessed with the IAT. As also observed in the previous research, explicit measures showed inconsistent cross-cultural patterns. Lastly, we observed little statistical within-culture coherence among the implicit measures of independence (vs. interdependence), consistent with a view that the implicit indices capture alternative ways for individuals to achieve the cultural mandate of independence or interdependence.
Interdependent selves show face-induced facilitation of error processing: Cultural neuroscience of self-threat.
(2014-01-01) Park, Jiyoung; Kitayama, Shinobu
The fundamentally social nature of humans is revealed in their exquisitely high sensitivity to potentially negative evaluations held by others. At present, however, little is known about neurocortical correlates of the response to such social-evaluative threat. Here, we addressed this issue by showing that mere exposure to an image of a watching face is sufficient to automatically evoke a social-evaluative threat for those who are relatively high in interdependent self-construal. Both European American and Asian participants performed a flanker task while primed with a face (vs control) image. The relative increase of the error-related negativity (ERN) in the face (vs control) priming condition became more pronounced as a function of interdependent (vs independent) self-construal. Relative to European Americans, Asians were more interdependent and, as predicted, they showed a reliably stronger ERN in the face (vs control) priming condition. Our findings suggest that the ERN can serve as a robust empirical marker of self-threat that is closely modulated by socio-cultural variables.
Social status and anger expression: the cultural moderation hypothesis

Individuals with lower social status have been reported to express more anger, but this evidence comes mostly from Western cultures. Here, we used representative samples of American and Japanese adults and tested the hypothesis that the association between social status and anger expression depends on whether anger serves primarily to vent frustration, as in the United States, or to display authority, as in Japan. Consistent with the assumption that lower social standing is associated with greater frustration stemming from life adversities and blocked goals, Americans with lower social status expressed more anger, with the relationship mediated by the extent of frustration. In contrast, consistent with the assumption that higher social standing affords a privilege to display anger, Japanese with higher social status expressed more anger, with the relationship mediated by decision-making authority. As expected, anger expression was predicted by subjective social status among Americans and by objective social status among Japanese. Implications for the dynamic construction of anger and anger expression are discussed.
Negative emotions predict elevated Interleukin-6 in the United States but not in Japan
(2013-01-01) Park, Jiyoung; Boylan, Jennifer Morozink; Coe, Christopher L.; Curhan, Katherine B.; Levine, Cynthia S.; Markus, Hazel Rose; Kitayama, Shinobu; Kawakami, Norito; Karasawa, Mayumi; Love, Gayle; Ryff, Carol D.
Previous studies conducted in Western cultures have shown that negative emotions predict higher levels of pro-inflammatory biomarkers, specifically interleukin-6 (IL-6). This link between negative emotions and IL-6 may be specific to Western cultures where negative emotions are perceived to be problematic and thus may not extend to Eastern cultures where negative emotions are seen as acceptable and normal. Using samples of 1044 American and 382 Japanese middle-aged and older adults, we investigated whether the relationship between negative emotions and IL-6 varies by cultural context. Negative emotions predicted higher IL-6 among American adults, whereas no association was evident among Japanese adults. Furthermore, the interaction between culture and negative emotions remained even after controlling for demographic variables, psychological factors (positive emotions, neuroticism, extraversion), health behaviors (smoking status, alcohol consumption), and health status (chronic conditions, BMI). These findings highlight the role of cultural context in shaping how negative emotions affect inflammatory physiology and underscore the importance of cultural ideas and practices relevant to negative emotions for understanding of the interplay between psychology, physiology, and health.
Error-related brain activity reveals self-centric motivation: Culture matters
(2013-01-01) Kitayama, Shinobu; Park, Jiyoung
To secure the interest of the personal self (vs. social others) is considered a fundamental human motive, but the nature of the motivation to secure the self-interest is not well understood. To address this issue, we assessed electrocortical responses of European Americans and Asians as they performed a flanker task while instructed to earn as many reward points as possible either for the self or for their same-sex friend. For European Americans, error-related negativity (ERN)-an event-related-potential component contingent on error responses--was significantly greater in the self condition than in the friend condition. Moreover, post-error slowing--an index of cognitive control to reduce errors--was observed in the self condition but not in the friend condition. Neither of these self-centric effects was observed among Asians, consistent with prior cross-cultural behavioral evidence. Interdependent self-construal mediated the effect of culture on the ERN self-centric effect. Our findings provide the first evidence for a neural correlate of self-centric motivation, which becomes more salient outside of interdependent social relations.
