The purpose of this research is to explore the relationship between parental attachment and state nostalgia by examining the effect of parental attachment priming (secure or insecure) on state nostalgia and four nostalgia cognitive appraisals. We expect that priming a secure, parental attachment will cause an increase in state nostalgia and nostalgia-based cognitive appraisals (H1), and priming an insecure, parental attachment will cause a decrease in nostalgia-based cognitive appraisals (H2).
