The study also investigated the roles of sex and spatial working memory (SWM). Participants completed two MR tasks, a Windows Mental Rotation (WMR) test and the Seria-Think\u2013MR (STI-MR) test, assessing generalization. Each task was administered before and after a single mediation session. Four major findings emerged. (a) Children who received individualized motoric mediation demonstrated significantly greater MR gains than control children on both tasks. (b) The intervention produced a generalization effect, with improvements observed even on the structurally distinct STI-MR task. (c) No significant sex differences or sex-related interactions were found. (d) The positive pre-intervention correlation between SWM and WMR weakened after mediation, suggesting reduced reliance on WM resources following the acquisition of more efficient MR strategies. Across both tasks, a consistent Degree of Rotation \u00d7 Time interaction indicated disproportionately larger gains at higher rotation angles, and children showed evidence of strategic reframing, particularly in interpreting 270\u00b0 rotations as equivalent to 90\u00b0 in the opposite direction. These findings support the theoretical framework of Structural Cognitive Modifiability and highlight the potential of motoric mediation to foster flexible spatial strategies. The results also underscore the educational value of integrating spatially rich, hands-on activities into early curricula and demonstrate the diagnostic utility of DA for identifying children\u2019s learning potential. Implications, limitations, and directions for future research are discussed.<\/jats:p>","DOI":"10.3390\/jintelligence14080162","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T01:43:27Z","timestamp":1785721407000},"page":"162","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cognitive Modifiability of Mental Rotation: Effects of Mediation, Sex, and Working Memory Among Third-Grade Students"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4291-4495","authenticated-orcid":false,"given":"David","family":"Tzuriel","sequence":"first","affiliation":[{"name":"Faculty of Education, Bar-Ilan University, 2 Anna Webb Street, Ramat Gan 5290002, Israel"},{"name":"Learning Disabilities Department, Talpiot Academic College, 7 Yotveta Street, Holon 5850019, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7626-8754","authenticated-orcid":false,"given":"Ravit","family":"Hozez Sagi","sequence":"additional","affiliation":[{"name":"School of Education, Ariel University, 65 Ramat HaGolan Street, Ariel 4077625, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Beckner, A.
