However, little research has been conducted on the differences in the visual and spatial processes involved in 3D versus 2D sketching and their effects on cognition. This study investigated potential differences in spatial and visual functions related to the use of 3D versus 2D sketching media by analyzing functional magnetic resonance imaging (fMRI) data. We recruited 20 healthy, right-handed students from the Department of Horticulture and Landscape Architecture with at least three years of experience in freehand landscape drawing. Using an Oculus Quest VR headset controller and a 12.9-inch iPad Pro with an Apple Pencil, we tested participants individually with 3D and 2D sketching, respectively. When comparing 2D and 3D sketches, our fMRI results revealed significant differences in the activation of several brain regions, including the right middle temporal gyrus, both sides of the parietal lobe, and the left middle occipital gyrus. We also compared different sketching conditions, such as lines, geometrical objects (cube), and naturalistic objects (perspective view of a tree), and found significant differences in the spatial and visual recognition of brain areas that support visual recognition, composition, and spatial perception. This finding suggests that 3D sketching environments, such as VR, may activate more visual\u2013spatial functions during sketching compared to 2D environments. The result highlights the potential of immersive sketching environments for design-related processes and spatial thinking.<\/jats:p>","DOI":"10.1371\/journal.pone.0294451","type":"journal-article","created":{"date-parts":[[2024,3,11]],"date-time":"2024-03-11T17:30:12Z","timestamp":1710178212000},"page":"e0294451","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["How three-dimensional sketching environments affect spatial thinking: A functional magnetic resonance imaging study of virtual reality"],"prefix":"10.1371","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9422-0378","authenticated-orcid":true,"given":"Yu-Hsin","family":"Tung","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6244-1977","authenticated-orcid":true,"given":"Chun-Yen","family":"Chang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,3,11]]},"reference":[{"key":"pone.0294451.ref001","author":"Aristotle","year":"1986","journal-title":"De Anima (On the Soul): Penguin Publishing Group"},{"issue":"2","key":"pone.0294451.ref002","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1080\/10400419109534381","article-title":"The dialectics of sketching","volume":"4","author":"G.
