  1. A Theoretical Framework for Investigating Human Factors in GIS Use: The Impact of Spatial Ability, Computer Aptitude, and Cognition Tonda Bone University of North Texas Dena Johnson Tarleton State University ISECON 2007

  2. Research Gap • Current research focuses on: • Spatial abilities in context of map reading task, cognitive map construction, wayfinding experiments • GIS as presentation device rather than as a problem-solving tool • Current research does not address: • Cognitive style dimensions in context of GIS use • Computer aptitude as factor in GIS use

  3. Research Gap • We need to understand how human factors influence GIS use • For academic purposes • GIS as a learning tool • GIS design • For industry • GIS design • GIS training

  4. What is an Information System? An information system “consists of • at least one PERSON • of a certain PSYCHOLOGICAL TYPE • who faces a PROBLEM • within some ORGANIZATIONAL CONTEXT • for which he needs evidence to arrive at a solution • and that the EVIDENCE is made available to him • through some MODE OF PRESENTATION” (Mason & Mitroff, 1973, p. 475, emphasis in original, bullets added).

  5. What is a Geographic Information System (GIS)? • A spatially-referenced information system that provides tools for collecting, managing, integrating, analyzing, and displaying data that is spatially referenced (Goodchild, Egenhofer, Kemp, Mark, & Sheppard, 1999; Turk, 1990) • Includes representations of locations, as well as non-spatial data (attributes) that describe those locations • A structure incorporating 5 elements (Turk, 1990): • Data • Hardware • Software • Procedures • People

  6. Spatial Cognition • “The knowledge and internal or cognitive representation of the structure, entities, and relations of space; in other words, the internalized reflection and reconstruction of space in thought” (Hart and Moore, 1973, p. 248) • 3 distinct factors of spatial ability • Spatial visualization • Spatial manipulation • Spatial relations

  7. Spatial Visualization • Ability to mentally manipulate spatial objects and configurations without referring to one’s self as a reference point (Albert & Golledge, 1999; Hegarty & Waller, 2005; McGee, 1979) • May be important to GIS in the function of moving map layers for analysis and for display, and for performing logical operations on spatial elements

  8. Spatial Orientation • Ability to imagine how a visual stimulus or configuration looks from a different perspective (Albert & Golledge, 1993) • May be important to GIS because operators have to change perspective when dealing with 3D representations before making inferences about the data (Albert & Golledge, 1993)

  9. Spatial Relations • Involves analyzing patterns, shape, layout, hierarchy, and linkage between individual stimuli within a visual configuration (Albert & Golledge, 1993; Gilmartin & Patton, 1984; Golledge, Dougherty, & Bell, 1995 ) • May be important in GIS functions of identifying and categorizing features, recognizing spatial association

  10. Map Reading Ability • Data interaction occurs primarily through the map interface; thus, map interaction also is an important component of GIS use (Lloyd & Bunch, 2003) • How does information acquisition from maps, including internal representation, influence GIS use?

  11. Human Spatial Information Processing • Hierarchical organization and categorization • Chunking • Category theory • Cognitive mapping • Of physical space • Of virtual (computer) space

  12. Mental models and problem solving • Mental modeling process “mirrors” GIS analysis processes (Turk, 1990) • Involves inferencing, context, cognitive load, and past experiences (Allen, 1996; Ramaprasad, 1987; Rauh, Knauff, Cuss, Schlieder, and Strube, 2005; Tversky, 1993) • Using GIS to model the problem space could aid mental modeling development

  13. Cognitive Styles • Example: Need for cognition (NFC) • Cohen, Stotland, and Wolfe (1955): NFC as a need to structure one’s environment • Crossland, Herschel, Perkins, and Scudder (2000): NFC as a measure “of an individual’s internal motivation to pursue and enjoy thinking activities” (p. 17)

  14. Computer Aptitude • Refers to literacy aspects of computer and Internet technologies • Computer use is a spatial task • Affects performance on mental rotations tests(De Lisi & Cammarano, 1996; Sacuzzo, Craig, Johnson, & Larson, 1996; Terlecki & Newcombe 2005)

  15. Summary: Main Human Factors in GIS Interaction • Spatial abilities • e.g., visualization, orientation, relations • Map reading abilities • Problem solving style • Mental models • Need for cognition • Cognitive Style • Computer attitude and efficacy

  16. Future Research • Computer attitude and efficacy • User interaction in context • Mental models of GIS spatial representations • Map sketching with GIS • Psychometric studies
