Spatial ability is "the aptitude needed to mentally process three-dimensional images of objects." (Fleisig et al. 2004).


"There is evidence which indicates that strong spatial skills are required for achievement in science, technology, engineering and mathematics (STEM) careers. Many people, including science and engineering professors, view such skills as important for success in fields like engineering." (Gutierrez, Dominguez, & Gonzalez, 2015)


"The level of spatial performance someone is capable of may change over time. You are likely to gain in performance through practice, training, and learning, but you may also lose in standing relative to others if they acquire more experience that supports their performance or make more progress in their intellectual development." (Johns Hopkins University, 2018)

If you wish to improve or retain the level of your spatial ability, hidden shapes will be the best option for you.
