In China, the innovative development of education for older people is an important response to the aging population, and an important way to meet the spiritual, cultural, and social needs of older people. Current academic research mainly focuses on the social factors that affect the participation of older people in education and there are few empirical studies on the individual psychological characteristics of older adult learning behavior. This study takes a positive psychology approach to the exploration of the factors influencing the participation of older adults in education in a number of universities of the Third Age in Fujian Province, China. The study is based on curriculum preferences and frequency of participation in extracurricular activities. The results show that the personality traits of extraversion and neuroticism, as well as gender, age, level of educational attainment, and family economic status significantly affect frequency of participation in extracurricular activities and the curriculum preferences of older learners. The results of this study suggest that we can strengthen personality matching to promote the learning enthusiasm of older people in education, and adhere to the demand-oriented to promote the Third age education curriculum personalized. Furthermore, we should increase the scope for popularizing Third age education, improve the accessibility of education for the older people, accelerate the integration of older adult education with the Internet, innovate the form of older adult education, and then promote the development of customized curricula.
