We often create or assemble objects by following instructions or manuals. In recent years, such manuals have increasingly been accessed in digital form through devices such as smartphones or tablets. However, little is known about how the medium of a manual (paper vs. digital) influences satisfaction with the creative experience. This study investigated the effects of manual format on psychological ownership of the manual, attachment to the created product, and satisfaction with the creative process. A between-participants design was employed with manual format (paper, digital) as the independent variable. A total of 156 undergraduate students (94 men, 60 women, 2 undisclosed; M = 19.43 years, SD = 1.11) participated. Participants were instructed to create an origami (traditional Japanese paper-folding) work for 15 minutes using either a paper or a digital manual. Afterward, they evaluated the manual's ease of understanding, their psychological ownership of the manual, their attachment to the product, and their satisfaction with the creative experience. Satisfaction was also assessed one week later. Results indicated that, while no difference emerged in perceived ease of understanding between formats, the paper manual fostered stronger psychological ownership of the manual, greater attachment to the product, and higher satisfaction with the creative experience. Importantly, this effect persisted one week later. Although digitization has accelerated in recent years due to convenience and environmental concerns, these findings underscore the enduring positive role of physical media in enriching creative experiences.
