摘要:Healthy aging is one of the most important aspects of human life as it can significantly improve its quality. Therefore, it is necessary to promote successful aging as a significant and important part of maintaining physical and mental well-being in the elderly. One of the strategies to enhance the elderly’s well-being may be also foreign language learning. The purpose of this study is to compare and discuss what effect foreign language learning (FLL) might have on subjective well-being among healthy older individuals in the Czech Republic and Poland, using factor analysis as the primary statistical method. The research sample consisted of two experimental groups of seniors; one from the Czech Republic (n = 92) and another from Poland (n = 100). The main research methods included a questionnaire survey and factor analysis. The factor analysis revealed the four significant factors and their correlations with demographic variables, whose results showed the effect of FLL on seniors’ subjective well-being. In conclusion, learning a foreign language at an older age seems to be one of the key strategies to maintain a subjective feeling of happiness at a relatively high level in elderly people without necessary pharmacological intervention.
