Background: One of the fundamental challenges for gerontological research is how to maintain and promote intact cognitive functioning in old age. Previous research revealed that high educational level, good health status, and an active lifestyle during adulthood seem to be protective against cognitive impairment in old age. However, up to now, a detailed examination of the interaction of these relations based on a broader variety of activities and considering past and current activities is missing. Objective: The present study set out to extend the literature by investigating in more detail the interactions of educational level and health status with a broad variety of past and current leisure activities in their association with cognitive functioning in a large sample of older adults with a wide age range. Methods: A total of 2,812 older adults (aged 65-101 years) served as the sample for the present study. A test on verbal abilities and one on processing speed were applied. In addition, individuals were retrospectively interviewed regarding their educational level, current general health status, and 18 leisure activities (in terms of currently performed activities and those that had been carried out at the age of 45 years). Results: Regressions indicated that engaging in more current activities and in more activities at the age of 45 years (both analyzed as an overall activity measure) was related to better cognitive performance in old age (r values up to 0.39, p values <0.001). These associations were more pronounced in individuals with a low (compared to a high) educational level. Conclusion: Present results suggest that an active lifestyle during middle adulthood may be related to better cognitive functioning in old age, particularly in individuals with a low educational level. These findings are discussed with respect to models of cognitive aging.

This paper deals with historical memory in Chile from a theoretical life course perspective. For this purpose, the topic is conceptualized on the basis of a collective and historical generation component concerning the memory of different age groups in the six municipalities of the metropolitan area of Concepción (Chile). The information was gathered by means of a standardized questionnaire, and the sample comprised individuals spread across fi ve different age groups. The results show a memory of recent history centered on national events for the whole sample, incorporating supranational elements among younger cohorts. The study confi rms the existence of both national and generational memories centered around various signifi cant socio-historical changes.

Whilst reflexive migration studies have criticised the use of categories such as ‘nationality’ and ‘second generation’ in quantitative research, several gaps on how to develop such reflexivity remain. In qualitative data, the co-construction of knowledge seems feasible during fieldwork, whereas the deductive process of quantitative research limits such interactions and is more at risk of reproducing a ‘state thought’. Through a longitudinal database, the LIVES-FORS cohort survey of the National Center of Competence in Research LIVES – Overcoming Vulnerability: Life Course Perspectives and FORS – the Swiss Centre of Expertise in Social Sciences (herafter LCS), we engage in this discussion and provide some answers. The LCS is an annual longitudinal survey that, in 2013, started following a cohort of young adults born between 1988 and 1997 who grew up in Switzerland. The underlying hypothesis of the LCS is that migrants’ descendants have access to different resources (and often a lack thereof) to Swiss natives. In this paper, we discuss both the theoretical and empirical challenges to using the categories ‘nationality’ and ‘second generation’. We show the fluidity and subjectivity of these categories. By changing the definition of the category ‘second generation’, we increased the proportion of ‘second-generation’ participants from 43 to almost 62% of the sample. Looking across the five waves of the survey, we notice a 2% unexplained variation in the first nationality mentioned by the participants and 31% missing values regarding the nationality at birth – which are both indicators that nationality is a subjective category as well as a legal one. We illustrate that the static and neutral conceptions of these categories reproduce a false and stigmatised image of migrant descendants. To avoid these pitfalls we suggest developing multilevel geographical comparisons to consider the effects of time (age and historical), to use a wider range of information in order to be more precise, to examine different nationalities instead of focusing on the traditional nationalities of labour immigrants in a given country and to explore the reasons for the lack of answers to certain questions. Thus the questionnaires should include both more flexibility in the possibilities for answers and details and more-open questions regarding sensitive issues about the definition of the self. They should be developed through a participative and bottom-up process fostering mixed methods.
