  1. Training Mental Rotation: A Comparison of Training Spatial Visualization and Working Memory Shannon Fitzhugh Jason Chein Alexandra Morrison Nora Newcombe Thomas F. Shipley

  2. Perception and Cognition withSpatial Representations http://www.spatialintelligence.org

  3. Training • What we know about training…. • Working Memory Training improves executive function and reading comprehension • Spatial Visualization Training improves Mental Rotation, help retain women in STEM disciplines (engineering) • What we don’t know about training…. • What is the mechanism? • Is the mechanism domain general (i.e. executive functioning) or domain specific (i.e. spatial ability) • Are the profiles of change the same for all groups of people? http://www.spatialintelligence.org

  4. Experimental Design http://www.spatialintelligence.org

  5. Methods • Results as Composite Z-Score • Verbal – average z-score for all verbal assessments (Nelson Denny, operation span) • Spatial – average z-score for all spatial assessments(Paper-and-pencil MRT-A, symmetry span, Paper folding (ETS), Surface development (ETS)) • Eye-tracking

  6. Training Paradigms Feedback Feedback http://www.spatialintelligence.org “N” times – adaptive portion • Verbal WM training (adaptive complex span) Lexical decision Memory item Response “N” times – adaptive portion 4 s 1 s • Verbal STM training (adaptive simple span) No Processing Memory item Response • Spatial Visualization Training (progressive workbook;Sorby, 2003)

  7. Measures: Nelson Denny Operation span http://www.spatialintelligence.org

  9. Visualization Training Facilitates Encoding http://www.spatialintelligence.org

  10. Eye Tracking: Gaze Change Working Memory Short Term Memory Spatial Visualization http://www.spatialintelligence.org

  11. Conclusions • Memory training improves both verbal and spatial abilities (improving attention). • Visualization training improves spatial skills (Improving encoding) • Training effects and individual spatial abilities • WM improves performance on WM tasks for all groups and MRT performance for all groups • Spatial Training improves performance on spatial tasks for high and low ability only – non-rotators remain flat http://www.spatialintelligence.org
