Subclaims¶

q2 i? Factor analysis identified three unique imagery factors — imagery quality, imagery speed and imagery self-report — where the CHC theory represents imagery as a single factor. → Jeffrey Buckley 2018 q2 i? Individuals differ both in the degree they are affected by visual illusions and in which illusions affect them, supporting five illusion factors. → Jeffrey Buckley 2018 (2)

Evidence¶

Jeffrey Buckley 2018¶

Jeffrey Buckley, Niall Seery, Donal Canty. (2018). A Heuristic Framework of Spatial Ability: a Review and Synthesis of Spatial Factor Literature to Support its Translation into STEM Education. Educational Psychology Review. https://doi.org/10.1007/s10648-018-9432-z

q2 · i? · review · r2

The review reports an extensive factor-analytic study following Carroll's recommendation, in which "Burton and Fogarty (2003) identified three unique imagery factors"; the self-report factor is described as a measure of belief of capacity, not an objective measure of the imagery factor.

"Burton and Fogarty (2003) identified three unique imagery factors which they posited as imagery quality, imagery speed and imagery self-report."

q2 · i? · review · r2

The review reports Coren et al.'s factor-analytic results, which Carroll described as a major factor-analytic study, supporting five individual illusion factors based on valid measures built from illusion geometry and behavioural effects.

"The findings suggest that individuals differ not only in the degree they are affected by visual illusions but also by which illusions affect them and include shape and direction illusions, size contrast illusions, overestimation illusions, underestimation illusions and frame of reference illusions."

• Twin and factor-analytic studies support a unitary single-factor model of spatial ability, as the review reports — related
