Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder Jan 2018

Differences In Spatial Visualization Ability And Vividness Of Spatial Imagery Between People With And Without Aphantasia, Anita Crowder

Theses and Dissertations

Mathematics education researchers have examined the relationship between visualization and mathematics for decades (e.g., Arcavi, 2003; Bishop, 1991; Duval, 1999; Fennema & Tartre, 1985; Presmeg, 1986). Studies have linked spatial visualization ability, such as measured in mental rotation tasks, directly to mathematics self-efficacy (Pajares & Kranzler, 1995; Weckbacher & Okamoto, 2014), which in turn influences mathematics achievement (Casey, Nuttall, & Pezaris, 1997). With the important role that spatial visualization plays in learning mathematics, the recent identification of congenital aphantasia (Zeman, Dewar, & Della Sala, 2015), which is the lack of mental imagery ability, has raised new questions for mathematics education …


Symmetry Identified In 2-Dimensional Artwork Compositions Using Visuospatial Ability, Theresa Ferg Jan 2018

Symmetry Identified In 2-Dimensional Artwork Compositions Using Visuospatial Ability, Theresa Ferg

Electronic Theses and Dissertations

At the John Langdon Down Foundation A.C. in the La Escuela Mexicana de Arte Down school in Mexico City D.F., Mexico, art students with Trisomy 21 display the use of a mathematical construct in the painting compositions of their artworks. The mathematical construct is a type of symmetry and it carries a positive affect. This is important because there have been no studies that have investigated the use of the symmetry in the artwork compositions of persons with Down syndrome. The geometric construction of the artwork compositions follows the artistic principle of the Rule of Three and the division of …
