Yayın Cognitive functions among healthy older adults using online social networking(Routledge, 2023-07-04) Yıldırım, Elif; Ögel Balaban, HaleOnline social network sites provide possibilities to enhance social relationships and engage in cognitive activities for older adults. The present study aimed to investigate the relationship between the use of one social network site, Facebook, and cognitive functions in older adults considering different dimensions of Facebook use together with different cognitive functions. Seventy healthy older adults completed the use of Facebook form, Multidimensional Scale of Perceived Social Support, and Social Network Index. Their cognitive functions were measured with Digit Span Tasks, Free and Cued Selective Reminding Test, Letter and Category Fluency Tests, Stroop Test, Digit Symbol Substitution Test, and Trail Making Test (TMT-A and TMT-B). After controlling for age, gender, education level, we found that Facebook users performed better on TMT-A compared to non-users. Among Facebook users, the length of having an account, the network size, the daily duration of use, and the frequency of active and passive use correlated with cognitive performance after controlling offline sociality. These findings, which need confirmation by experimental and longitudinal studies, suggested that being connected to a larger network via more prolonged and active use of social media might be associated with higher cognitive functioning.Yayın Cognitive reserve and aging: impacts on theory of mind and executive functions(Routledge, 2025-03) Şandor, Serra; Hıdıroğlu Ongun, Ceren; Yıldırım, ElifAim: This study examines the effects of cognitive reserve (CR) on Executive Functions (EF) and Theory of Mind (ToM). While CR is suggested to mitigate age-related cognitive decline, its relationship with social cognition remains limited and inconsistent in the literature. It was hypothesized that the effect of CR on ToM might be indirect, mediated by EF and working memory. Methods: 225 cognitively healthy participants were included. CR was measured with the Cognitive Reserve Index Questionnaire, EF with verbal fluency and the Stroop Test, and WM using digit span tasks. Structural Equation Modeling was used to analyze the relationships among CR, EF, WM, and SC, controlling for age and gender. Results: CR was significantly associated with both RMET and FPRT performances. Mediation analysis revealed the direct effects of CR on RMET performance, while the effects on FPRT performance were mediated by executive functions. WM had a partial mediating effect on EF and ToM, but did not directly influence FPRT. Education was most strongly associated with RMET performance, while leisure activities were linked to FPRT performance. Conclusion: These findings suggest that CR indirectly supports ToM by enhancing EF and highlight the importance of interventions aimed at strengthening executive control to support social cognition in aging.
