Spatial Thinking vs Spatial Ability

(Lohman, 1993; McGrew, 2009)

Uttal et al., 2012; Hegarty & Waller, 2005

Ability •An aspect of “g”•Domain-general•Apprehending, encoding, and mentally manipulating three-dimensional forms

Thinking / Skills•Domain-specific•Problem – solving with space, representation, and reasoning
