on perceived physical and mental health, level of extraversion, and level of activity. The associations between activity level and each variable were examined by comparing results with low, moderate, and high activity levels of extraverted individuals. Findings of this study reveal that there is a strong, positive correlation between extraversion and activity level, with participants indicating that a high activity level was most likely paired with the perception of good mental and physical health. Another study analyzed the aging population's ability to "describe a friend" by utilizing the theory of mind, which describes an individual's capacity to understand other people by ascribing mental states to them. This research aimed to investigate the relationship between activity level, older people's social relationships, and their associated theory of mind. 72 participants aged 60–79 from northern Italy were recruited to describe their best friend, with stories being transcribed and coded based on the level of detailed vocabulary used. This was followed with a questionnaire that examined the participants' activity level and cognitive functioning. Findings revealed that, although data was variable among the sample group, there was a slight positive correlation between high activity level, high affinity to social relationships, and ability to utilize theory of mind. A different qualitative study aimed to investigate the impact of an intergenerational exchange between undergraduate students and nursing home residents on the social engagement and self-esteem of the elderly. 13 older adult participants residing in an assisted living community in the rural Rocky Mountains were surveyed about their preferences of entertainment from childhood. From this survey, undergraduate researchers chose and viewed two movies with their paired participants. Nursing home residents were then interviewed about their level of enjoyment or disdain from the movie-viewing experience. Results of this study show a positive correlation among meaningful intergenerational exchanges, use of activity theory, and social engagement in the aging population. Overall, these research findings, among others, have provided important evidence for social scientists to inform policy making and service provision that supports active aging.
