A Theoretical Framework for Investigating Human Factors in GIS Use: The Impact of
Spatial Ability, Computer Aptitude, and Cognition
(2)
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
(3)
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).

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)
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)
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)
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)
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)
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
(11)
11
Human Spatial Information
Processing
• Hierarchical organization and categorization
• Chunking
• Category theory
• Cognitive mapping
• Of physical space
(12)
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)
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)
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)
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
(16)
16
Future Research
• Computer attitude and efficacy
• User interaction in context
• Mental models of GIS spatial
representations
• Map sketching with GIS
