How To Improve Spatial Skill: Converging on Mechanism Alexandra Morrison Temple University Acknowledgements Spatial Intelligence Learning Center & Temple University Neurocognition Lab Nora Newcombe Jason Chein Tim Shipley Graduate Students Alexandra Morrison Shannon Fitzhugh Research Staff Dominique Dumay Mike Demers Danielle Eagan Adrienne Villagomez 3 Questions • Why Train Spatial Skills? • How can we train spatial skills? • What are the results of different training approaches? – In progress data Why Spatial? How did you get to San Diego for Aera? Pack a Suitcase? Read a map? Navigate a busy airport? Why Spatial? Scientific Thought and Communication • STEM Disciplines – – – – Science Technology Engineering Math Why Spatial? Predicts choice of STEM Major – Higher spatial ability is associated with choice of STEM major (Hedges and Chung) • Controlling for IQ & SES • Equal in gender – SATM also related to choice of STEM discipline (Shae, Lubinski, & Benbow, 2001) How can we train spatial skills? • Two Approaches – Strategy 1: Train Spatial Skills – Domain Specific Approach – Strategy 2: Train shared mental resources – Domain general Approach Approach 1: Train Domain Specific Skills • Can train spatial skills by 1. Familiarizing participants with spatial stimuli A. B. 2. geometric shapes Shepard-Metzler Cubes Practice spatial Transformations Approach 1: Example of Domain Specific Spatial Training • Wright, Thompson, Ganis, Newcombe, & Kosslyn, 2008 – Trained in either mental rotation or paper folding – Transferred to nontrained spatial but not verbal task – Results domain specific but not task specific Approach 2:Domain General Training • Repetitive mental exercise improves general cognitive abilities •Small scientific literature supports this Approach 2: Domain General Cognitive Training An emerging science of cognitive training … Demonstrates 1. Performance also relies on general cognitive abilities 2. General cognitive abilities are both malleable & trainable. Approach 2: Working Memory Training • • • WM capacity is a domaingeneral resource WM capacity predicts performance in a broad range of tasks(e.g., Kane et al., 2004) Successfully trained •Klingberg, 2002 & 2005 • Vaerhaghen, 2004 • Jaeggi, 2008 Language Comp. Fluid Verbal Intelligence Reasoning Problem Solving WM Spatial Reasoning Working Memory vs. Short Term Memory • Working Memory (WM) – Simultaneous storage and processing • Short Term Memory (STM) – Storage only What do we find when we compare types of training? • Our goals 1. Look at the malleability of spatial skills 2. Contrast different Cognitive Training Paradigms Domain Specific Spatial Visualization Training Verbal Short Term Memory Training Domain General Verbal Working Memory Training 3. Determine Transfer Patterns Training Methods Overview Pre-test of cognitive skill level Spatial Visualization Training Working Memory Training Short Term Memory Training Post-test of cognitive skill level Cognitive Assessment Battery – MRT-A (Peters, 1995) – Solid Object Mental Rotation Test (Fitzhugh, Shipley, Newcombe & Dumay (in prep.) – Spatial/Verbal STM • Storage only – Spatial/Verbal WM • Storage + processing – Verbal Reasoning • Non-sense syllogisms, Inference – Cognitive Control • Stroop – Spatial Reasoning • Paper Folding, Surface Development – Reading Comprehension • Nelson Denny Training Regimes • 5 days a week – 30 min per day • 4 weeks of training • Trained at home while guided by lab staff Training Type 1: Spatial Visualization Training • Domain Specific Spatial Training • Introduction to 3D Visualization (Sorby, 1996) – Focus on transforming 3D objects into 2D representations • • • • Isomorphic – 2D perspective rendering Orthographic – 2D flat projections Surface Development Rotation about one axis Working Memory Training C Glib X • Domain general task Foot •Storage + Processing T Prust P Mile •Adaptive Difficulty Short Term Memory Training C • Domain Specific Verbal **** X • Storage only **** – 4s interval T **** P **** • Adaptive difficulty Results of In Progress Study (n=91) • Examine the following Questions: Do different types of training yield different results? What is the impact of each training type on: 1. Spatial Skills 2. STM (storage only) 3. WM (storage and information processing) Differential Effects of Training Does the type of Training Matter?

Summary Working Memory Training – WM training transfers to non-trained domains • WM training spatial visualization measures • Also transferred to cognitive control measure Summary Short Term Memory Training – Transfer to verbal tasks – Some Transfer to spatial tasks • May approximate WM training at longer list lengths (Unsworth & Engle, 2007) Future Directions • Trivia Training Control Group • Examine eye movement data – Looks like Spatial training and WM may improve by different mechanisms • 3 month follow-up – Are improvements stable?
