A Cross-Cultural Analysis of Imagined Interactions

This study compared the accuracy and confidence of Japanese and American participants on the Interpersonal Perception Task (IPT-15). The IPT contains 15 brief, real-life scenes on videotape for which there are objectively correct answers about relationships and deception. A total of 344 participants were run in a 2 (Japanese vs. American participants) × 2 (Audiovisual vs. Visual-Only presentation) × 2 (Sex of participant) design. Support was found for the hypothesized greater accuracy of Americans over Japanese, but a Culture × Presentation Modality interaction qualified the main effect of culture. Specifically, Japanese and American participants had virtually identical scores on the IPT-15 in the Visual-Only condition, but Americans' scores increased while Japanese scores decreased in the Audiovisual condition. Analyses of the confidence measures indicated that American participants were much more confident than the Japanese participants, but this difference was larger in the Audiovisual condition than in the Visual-Only condition. In addition, the prediction that women would be more accurate on the IPT, but still report lower confidence than men, was also supported. Finally, Japanese participants with moderate proficiency in spoken English were more accurate on the IPT than those with low English proficiency. The likely processes underlying these differences and the possible directions for future research are discussed.

BackgroundFrom the viewpoint of human physiological adaptability, we previously investigated seasonal variation in the amount of unabsorbed dietary carbohydrates from the intestine after breakfast in Japanese, Polish and Thai participants. In this investigation we found that there were significant seasonal variations in the amount of unabsorbed dietary carbohydrates in Japanese and Polish participants, while we could not find significant seasonal variation in Thai participants. These facts prompted us to examine seasonal variations in the respiratory quotient after an overnight fast (an indicator of the ratio of carbohydrate and fat oxidized after the last meal) with female university students living in Osaka (Japan), Poznan (Poland) and Chiang Mai (Thailand).MethodsWe enrolled 30, 33 and 32 paid participants in Japan, Poland and Thailand, respectively, and measurements were taken over the course of one full year. Fasting respiratory quotient was measured with the participants in their postabsorptive state (after 12 hours or more fasting before respiratory quotient measurement). Respiratory quotient measurements were carried out by means of indirect calorimetry using the mixing chamber method. The percent body fat was measured using an electric bioelectrical impedance analysis scale. Food intake of the participants in Osaka and Poznan were carried out by the Food Frequency Questionnaire method.ResultsThere were different seasonal variations in the fasting respiratory quotient values in the three different populations; with a significant seasonal variation in the fasting respiratory quotient values in Japanese participants, while those in Polish and Thai participants were non-significant. We found that there were significant seasonal changes in the percent body fat in the three populations but we could not find any significant correlation between the fasting respiratory quotient values and the percent body fat.ConclusionsThere were different seasonal variations in the fasting respiratory quotient values in the three different populations. There were significant seasonal changes in the percent body fat in the three populations but no significant correlation between the fasting respiratory quotient values and the percent body fat.

Healthy ageing has become a popular topic worldwide. So far, a consensus measure of healthy ageing has not been reached; and no studies have compared the magnitude of socio-economic inequality in healthy ageing outside Europe. This study aims to create a universal measure of healthy ageing and compare socio-economic inequalities in healthy ageing in the United States of America (USA), England, China and Japan. We included 10,305 American, 6,590 English, 5,930 Chinese and 1,935 Japanese participants for longitudinal analysis. A harmonised healthy ageing index (HAI) was developed to measure healthy ageing multi-dimensionally. Educational, income and wealth rank scores were derived accounting for the entire socio-economic distribution and the sample size of each category of socio-economic indicator. Associations between socio-economic rank scores and HAIs were assessed using multi-level modelling to calculate the Slope Indices of Inequality. Healthy ageing trajectories were predicted based on the full-adjusted age-cohort models. We found that education was a universally influential socio-economic predictor of healthy ageing. Moving from the highest to the lowest educational groups was associated with a 6.7 (5.2–8.2), 8.2 (6.0–10.4), 13.9 (11.4–16.3) and 6.1 per cent (3.9–8.2%) decrease in average HAI at 60 years in the USA, England, China and Japan, respectively. After 60 years, the educational inequality in healthy ageing kept increasing in the USA and China. The educational inequality in healthy ageing in China was also greater than any other socio-economic inequality in the four countries. Wealth was more influential in predicting healthy ageing inequality among American, English and Japanese participants, while income was more influential among Chinese participants. The socio-economic inequality in healthy ageing in Japan was relatively small. Chinese and American participants had worse healthy ageing profiles than Japanese and English participants.

The direction of gaze automatically and exogenously guides visual spatial attention, a phenomenon termed as the gaze-cueing effect. Although this effect arises when the duration of stimulus onset asynchrony (SOA) between a non-predictive gaze cue and the target is relatively long, no empirical research has examined the factors underlying this extended cueing effect. Two experiments compared the gaze-cueing effect at longer SOAs (700 ms) in Japanese and American participants. Cross-cultural studies on cognition suggest that Westerners tend to use a context-independent analytical strategy to process visual environments, whereas Asians use a context-dependent holistic approach. We hypothesized that Japanese participants would not demonstrate the gaze-cueing effect at longer SOAs because they are more sensitive to contextual information, such as the knowledge that the direction of a gaze is not predictive. Furthermore, we hypothesized that American participants would demonstrate the gaze-cueing effect at the long SOAs because they tend to follow gaze direction whether it is predictive or not. In Experiment 1, American participants demonstrated the gaze-cueing effect at the long SOA, indicating that their attention was driven by the central non-predictive gaze direction regardless of the SOAs. In Experiment 2, Japanese participants demonstrated no gaze-cueing effect at the long SOA, suggesting that the Japanese participants exercised voluntary control of their attention, which inhibited the gaze-cueing effect with the long SOA. Our findings suggest that the control of visual spatial attention elicited by social stimuli systematically differs between American and Japanese individuals.

We examined whether mental contrasting inhibits the pursuit of difficult goals in an Eastern culture-Japan-rooted in self-improvement. Our pilot study found that, compared with American participants, Japanese participants did not perceive a difficult situation as a cue to abandon their goal and pursue alternative objectives. Studies 1a-1c found that mental contrasting encouraged Japanese participants to pursue difficult goals. When Japanese participants perceived their own goals as unattainable, they were more likely to pursue these goals if they mentally contrasted their desired future with the inhibiting reality than if they simply imagined their desired future. Study 2 showed that mental contrasting encouraged Japanese (but not American) participants to pursue difficult goals. Study 3 evidenced the causal effect of beliefs about difficulties on the impact of mental contrasting on motivation to pursue difficult goals. Culturally formed beliefs about difficulties underlie the effect of mental contrasting on difficult goal pursuit.

We predicted and supported the prediction that a ‘preference‐expectation reversal’ would occur among Japanese but not among Americans. American and Japanese participants evaluated ideal‐typical independent and interdependent persons on the negative–positive dimension, and estimated how others would evaluate these persons. They also indicated their preference for acting like each of the target persons; that is, which of the two target persons they would prefer to act like. Both the American and Japanese participants wanted to act like the typical independent person rather than the typical interdependent person. However, the Japanese participants expected that others would evaluate the interdependent person more positively than the independent person. This preference‐expectation reversal was not observed among the American participants. Further analysis demonstrated that the American participants' personal evaluations of the two targets were consistent with their preferences. The Japanese participants' personal evaluation represented a compromise between their preferences and the expected responses of others. These results suggest that the culturally shared belief in Japan that interdependent persons would receive more positive evaluations than independent persons created an incentive for them to behave interdependently despite their preferences.

To test the argument that “face” is a fundamental cause of interpersonal conflict and explore the similarities and differences of conflict resolution between Thai and Japanese MNCs participants. Additionally, the correlation between face concerns and conflict management styles of the two cultures was examined. The research explored the Face-Negotiation theory (FN) version 2 to test that “face” is an underlying assumption and/or an explanatory mechanism for conflicts in the organization. The adapted version of Rahim Organization Conflict Inventory-II (ROCI-II) was employed to test the differences and similarities of conflict management styles. There were a total of 155 returned questionnaires. Moreover, 6 out of 155 participants were purposively selected for in-depth interviews by using Personal Attitude Construct (PAC) analysis. The findings of this research illustrated that “face” is a fundamental cause of interpersonal conflict for Thai and Japanese participants. Thais rated themselves higher for all types of face concerns: self-face, other-face, and mutual-face, than Japanese. Regarding the similarities and differences of conflict resolution, Thai participants preferred using integrating, avoiding, obliging and compromising more than Japanese participants. The relationship between face concerns and conflict management style showed that the more self-face and other-face concerned the Thai participants were, the more they reported using obliging. Additionally, the more mutual-faced concerned they were, the more they reported using integrating. Whereas for Japanese participants, the more self-face concerned they were, the more they reported using dominating. Additionally, the more other-face concerned and the more mutual-face concerned they were, the more they reported using integrating. Most of the findings from the PAC analysis (interview) supported the results of the quantitative parts (questionnaire); however, the preferences in styles of conflict resolution for Thais found some differences.

Cultural differences in the perception of positive affect intensity within an advertising context were investigated among American, Japanese, and Russian participants. Participants were asked to rate the intensity of facial expressions of positive emotions, which displayed either subtle, low intensity, or salient, high intensity expressions of positive affect. In agreement with previous findings from cross-cultural psychological research, current results demonstrate both cross-cultural agreement and differences in the perception of positive affect intensity across the three cultures. Specifically, American participants perceived high arousal (HA) images as significantly less calm than participants from the other two cultures, while the Japanese participants perceived low arousal (LA) images as significantly more excited than participants from the other cultures. The underlying mechanisms of these cultural differences were further investigated through difference scores that probed for cultural differences in perception and categorization of positive emotions. Findings indicate that rating differences are due to (1) perceptual differences in the extent to which HA images were discriminated from LA images, and (2) categorization differences in the extent to which facial expressions were grouped into affect intensity categories. Specifically, American participants revealed significantly higher perceptual differentiation between arousal levels of facial expressions in high and intermediate intensity categories. Japanese participants, on the other hand, did not discriminate between high and low arousal affect categories to the same extent as did the American and Russian participants. These findings indicate the presence of cultural differences in underlying decoding mechanisms of facial expressions of positive affect intensity. Implications of these results for global advertising are discussed.

To enhance satisfaction, the cosmetics industry needs to clearly understand consumers' descriptions of their key tactile preferences. It is difficult for researchers to understand verbal descriptions from people whose native language is different from their own. Previous research has implied that some sensory words with the same lexical meanings have been observed in different haptic exploratory procedures (HEPs). Therefore, our study aims to investigate and understand the key tactile perceptions of people from five different countries based on their descriptions and their HEPs. In Experiment 1, 1545 participants living in the US, Japan, China, Italy, and Thailand described their major tactile perceptions as efficacy in skincare, and we analysed the frequency of each word used in their answers. In Experiment 2, we confirmed the task to observe HEPs for Chinese, Italian, and Thai participants. A total of 24 participants in China, 33 participants in Italy, and 30 participants in Thailand freely explored their faces with their hands and answered which side more closely matched the major tactile adjectives. Experts classified the observed HEPs into six classifications within two categories and three contact area sizes and investigated the cultural differences. More than 2% of the Chinese, Italian, Thai, US, and Japanese participants described 33, 20, 29, 22, and 18 words, respectively, as efficacy in skincare. Verified words that described the major tactile perceptions in each native language had the same meanings as moistness, firmness, softness, smoothness, and so on. We could confirm the HEPs of these major feelings for the participants from each culture. Chinese and Thai participants' HEPs for moistness or softness were observed with a pressing movement. Conversely, Italian participants' HEPs for moistness or softness were observed with a rubbing movement. This study showed that words with the same lexical meanings evoked different HEPs. The results imply that different HEPs can provide different physical stimuli on the skin. Therefore, it is important to survey both objects and HEPs to better understand the tactile experience.

The Alzheimer’s Disease Neuroimaging Initiative showed that Japanese had significantly lower brain Aβ burden than Americans among a cognitively normal population. This cross-sectional study aimed to compare vascular disease burden, Aβ burden, and neurodegeneration between cognitively normal elderly Japanese and Americans. Japanese and American participants were matched for age (±4-year-old), sex, and Apolipoprotein E (APOE) genotype. Brain vascular disease burden and brain Aβ burden were measured using white matter lesions (WMLs) and 11C-labeled Pittsburgh Compound B (PiB) retention, respectively. Neurodegeneration was measured using hippocampal volumes and cortical thickness. A total of 95 Japanese and 95 Americans were recruited (50.5% men, mean age = 82). Compared to Americans, Japanese participants had larger WMLs, and a similar global Aβ standardized uptake value ratio (SUVR), cortical thickness and hippocampal volumes. Japanese had significantly lower regional Aβ SUVR in the anterior ventral striatum, posterior cingulate cortex, and precuneus. Cognitively normal elderly Japanese and Americans had different profiles regarding vascular disease and Aβ burden. This suggests that multiple risk factors are likely to be involved in the development of dementia. Additionally, Japanese might have a lower risk of dementia due to lower Aβ burden than Americans. Longitudinal follow-up of these cohorts is warranted to ascertain the predictive accuracy of these findings.

This study examined cognitive and affective responses of Japanese (N=199) and American participants (N=194) to the depiction of gender in a Japanese animé popular in both countries. As expected, Japanese respondents indicated more familiarity with the animation and also reported that they were fans to a greater extent than Americans. Japanese participants and males showed greater agreement with sex stereotyping in the depiction of characters. Males also showed greater liking for characters and expressed the belief that they were positive role models. American females disliked the characters, especially the female character, significantly more than all other participants. Finally, participants, regardless of country, who held conventional views of gender perceived fewer stereotypes in the depiction of the characters. Given the current interest in animé, implications of findings from viewing sex-stereotypical images and directions for future research are discussed.

This study investigated how the display rules of emotional expression apply in vocal-only communication depending on speakers’ and listeners’ cultural backgrounds and their similarities and differences. A comparison was made between Japanese and North American participants, who listened to emotional phrases spoken in their native language and a non-native language (English and Japanese, respectively). The participants were instructed to listen carefully to the recordings and judge the speakers’ true emotions. The speakers had been asked to express an emotion with their voice that was either congruent or incongruent with the emotion contained in the literal meaning of speech (ELMS), which, in English, corresponded to: “eleven-thirty,” “good afternoon,” “congratulations,” “I love it,” “I’m going to cry,” and “my heart is breaking.” The speakers spoke these utterances in neutral, happy, and sad voices. The results indicated that the Japanese listeners integrated the ELMS with the vocal emotions when the speakers were Japanese but judged the speakers’ emotions based on voice alone when the speakers were North American. This implied that Japanese participants could infer the speakers’ true emotions even when the ELMS was incongruent with vocal emotion. The results obtained from the Japanese and North American speakers and listeners were compared.

Social discounting occurs when participants share more of a reward with individuals with whom they are close to, relative to those more distant individuals. Previous social discounting studies have shown consistent effects of drug use and reward magnitude on sharing. However, previous cross-cultural social discounting studies have not incorporated reward magnitude or drug use as factors that may influence discounting. The current experiment randomized 569 American and Japanese university students into either a standard ($150; ¥15,500) or large ($1,500; ¥155,000) magnitude condition where participants made choices about allocating hypothetical rewards to individuals at varying social distances. Participants also self-reported cigarette and alcohol use. There was no social discounting difference between American and Japanese participants at the standard reward magnitude. However, American participants shared more than Japanese participants at the large reward magnitude, replicating a previous study. Only Japanese participants showed a magnitude effect. Including age, gender, or cigarette and alcohol use as covariates did not change the main findings. However, similar to previous social discounting studies, cigarette use was a significant predictor for social discounting. Cross-cultural social discounting differences between American and Japanese participants were accounted for by reward magnitude.

Social discounting is when resource allocation decreases as social distance increases. Studies fitting different quantitative models to social discounting data have shown that a q-exponential function based on Tsallis' statistics best fits loss data, whereas a hyperbolic power function best fits gain data. However, a social discounting sign effect, where losses are discounted less than equivalent gains, has not been consistently found. This study fit four different quantitative social discounting models to gain and loss data for 40 United States (US) participants. We compared quantitative model fits to previous studies collected with Japanese and German participants to determine if (1) different quantitative social discounting models best fit loss and gain data, (2) US participants discounted less gains than Japanese participants, but not losses, and (3) US participants showed the sign effect. Results showed that the q-exponential function and the hyperbolic power function best fit median loss and gain data, respectively. There were no significant absolute differences between cultures for gains or losses, and US participants showed a robust sign effect. While most results for US participants were consistent with previous data, future cross-cultural social discounting studies are needed that manipulate sign as well as reward magnitude to determine best quantitative model fits. Social discounting results are also discussed in relation to their application to important health behaviors such as smoking and obesity.

Collective memories are shared representations of a group’s past. For nations, these memories serve important purposes: they shape national identity, promote social cohesion and guide future decisions. Although extensive research has examined collective memory in Europe and the United States, less is known about countries outside these regions, such as Japan. Cultural tightness and other societal differences may influence the extent to which collective memories serve these functions. To address this issue, we first asked Japanese participants to nominate nationally important collective memories (Study 1), and then asked both Japanese and American participants to report the extent to which their country’s collective memories serve directive, social and identity functions (Study 2). Surprisingly, Japanese participants showed agreement on relatively few collective memories and rated those memories as serving these functions to a lesser degree than did Americans. These findings raise questions about how cultural tightness, institutional influences and educational systems shape collective memory and its functions. We suggest that in Japan, national identity may rely more on structural and cultural continuity than on shared recollections of specific historical events.
