As individuals from different nations increasingly interact with each other, research on national in-group favoritism becomes particularly vital. In a cross-national, large-scale study (N = 915) including representative samples from four Latin American nations (Chile, Peru, Colombia, Venezuela) and the USA, we explore differences regarding nationality-based in-group favoritism. In-group favoritism is assessed through differences in prosocial behavior toward persons from the own nation as compared to persons from other nations in fully incentivized one-shot dictator games. We find strong evidence for national in-group favoritism for the overall sample, but also significant differences among national subsamples. Latin Americans show more national in-group favoritism compared to US Americans (interacting with Latin Americans). While US Americans mainly follow an equal split norm (for both in- and out-group interactions), Latin Americans do so only in in-group interactions. The magnitude of in-group favoritism increases with social distance toward the out-group.

Theories of trust distinguish general trust in situations of social uncertainty from assurance-based trust in committed, long-term relationships. This study investigates European-Japanese differences using the Centipede game, in which two players choose between cooperation and defection. The game models repeated reciprocal interactions, necessitating assurance-based trust to sustain cooperation. We included game conditions offering players the option of purchasing commitment-enhancing tools to increase social certainty. Japanese participants were more cooperative than Europeans, confirming higher assurance-based trust, and also purchased more commitment-enhancing tools, demonstrating their preferences for social certainty. Purchase of commitment-enhancing tools improved cooperativeness in both groups. However, if co-players refused tool purchase, the Japanese appeared to interpret this as non-cooperative intent and cooperativeness in the respective games decreased.

Research has demonstrated that holding a young subjective age (i.e. feeling younger than one's chronological age) has been associated with various positive aspects of physical and psychological health. However, little is known about how such associations differ between cultural sub-groups within a given society. Accordingly, the current study focused on the Israeli component of the Survey of Health, Ageing and Retirement in Europe (SHARE-Israel) and aimed to explore the moderating role of culture on the association between subjective age and objective physical health, subjective physical health and psychological health. Data were collected from 1,793 respondents, who were classified into three groups: veteran Israeli Jews, immigrants from the former Soviet Union and Israeli Arab citizens. Age ranged from 50 to 105 (mean = 69.65, standard deviation = 9.49). All participants rated their subjective age and filled out scales examining six dimensions covering psychological health, as well as objective and subjective physical health. Across all examined dimensions, an older subjective age was associated with unfavourable health outcomes. For the majority of health dimensions, the subjective age–health links were most prominent among Israeli Arabs. Results are discussed from both a general societal standpoint (i.e. group differences in access to health services), as well as from the individual's specific role in his or her culture and society.

This study investigates the changes in social network types among older adults in South Korea, and it examines whether, and to what extent, these changes influence their health and psychological wellbeing. Data were obtained from the Korean Longitudinal Study of Ageing. The sample was restricted to respondents over 65 years of age who participated in both the 2006 and 2008 surveys (N = 3,501). The social network types for both years were derived by Latent Class Analysis. Changes in network types over time were then identified. A series of multivariate regression analyses were conducted to examine the effects of social network changes on self-rated health, depressive symptoms and life satisfaction. Restricted, Family, Friend and Diverse network types were derived in each wave of the study. Although the direction of social network changes was not always towards the Restricted type, the Restricted network was the most prevalent and stable type among older Koreans. Older adults who remained in or transitioned to restricted types of social networks were more likely to have poor self-rated health, higher levels of depressive symptoms and lower levels of life satisfaction. This study adds to the limited body of literature on longitudinal network typology, and it expands the knowledge of social network types among older adults in diverse social and cultural contexts.

Background: Many minority ethnic (ME) older adults face several culturally associated and systemic barriers to timely dementia diagnoses that may result in delays to dementia care-seeking. We aimed to develop and propose a model illustrating variables that influence dementia care-seeking among ME older adults.

Methods: We conducted a literature review on the effects of these barriers on diagnostic delays and impairment levels at initial evaluation. We also strived to provide a basis for the Sociocultural Health Belief Model (SHBM) to guide future research and service planning pertaining to culture and dementia care-seeking.

Results: There was consistent evidence that ME older adults with dementia tended to have greater diagnostic delays and higher levels of cognitive impairment and behavioral and psychological symptoms of dementia at initial evaluation than their non-Hispanic White counterparts. We also found several barriers to dementia care-seeking among ME groups. These barriers included lower levels of acculturation and accurate knowledge about dementia, more culturally associated beliefs about dementia, such as the perception of memory loss as normal aging and stigma associated with dementia, and health system barriers.

Conclusions: The SHBM provides an empirically based conceptual framework for examining cross-cultural differences in dementia care-seeking among diverse groups. We provide recommendations for future research, such as the need for research with more diverse ethnic subgroups and the examination of group-specific cultural values. We conclude with a discussion of the clinical and service implications of our review, including potential interventions aimed at facilitating timely dementia diagnoses among ME older adults.

Loneliness is experienced in many cultures. To properly assess cross-cultural differences, attention should be paid to the level, determinants, and measurement of loneliness. However, cross-cultural studies have rarely taken into account more than one of these. Differences in the level of loneliness were hypothesized on the basis of national differences in partnership, kinship, and friendship, which were assumed to be related to cultural standards within a society. Differences were examined among married and widowed older adults aged 70 to 89 years living independently in the Netherlands (N = 1,847), Tuscany, Italy (N = 562), and Manitoba, Canada (N = 1,134). Loneliness was measured with an 11-item scale. The Manitobans were high on emotional loneliness and the Tuscans were high on social loneliness. Partner status excepted, the determinants were nearly the same across the three locations. Differential item functioning (DIF) related to the three locations was observed for most items. Interactions with gender and the availability of a partner relationship were observed.

This article provides a commentary on a set of five other articles reporting European and Canadian studies of loneliness among seniors. It places those works involving Canadian, Dutch, Finnish, and Welsh samples in the larger context of research on loneliness; offers reflections on the methods and findings reported in the articles; and addresses the question, Is loneliness universal? Points of similarity in the articles are identified and possible ways of reconciling discrepant findings regarding age trends and gender differences are put forward. A discrepancy model of loneliness is used as a key framework for explaining several points, including why objective social isolation and loneliness don't always go together.

The aim of this postal survey was to highlight differences in temperament and behaviour between 32 toddlers in Japanese families living temporarily in London and 36 in British families, all in London. Mothers completed questionnaires about demography, perinatal events, and their child's temperament and behaviour. UK toddlers were described as exhibiting fewer behavioural symptoms than Japanese toddlers. Significantly more of the Japanese toddlers scored above the cutoff on the Behaviour Check List, indicating higher levels of behavioural disturbance. An interesting item is ‘sleeping with parent’, which occurs commonly in Japanese families and is considered to be normal for that culture. On the Toddler Temperament Scale the Japanese toddlers proved more distractable and more intense than the UK toddlers when age had been allowed for. It was of interest that Japanese girls proved more distractable than Japanese boys and UK girls. Possible explanations for the differences are advanced.
