  • Role of spatial experience and spatial intelligence
  • Research across the disciplines
  • National attention, especially in psychology and engineering
caution
Caution
  • Gender research results can be used to examine characteristics of groups, not to predict success or failure of individuals. Ability levels can and do overlap between the sexes.

(Halpern, 2000)

spatial ability spatial intelligence
Spatial Ability/Spatial Intelligence
  • Not one ability, consists of many abilities. It is the skill in visualizing, creating, manipulating, rotating, perceiving, and remembering information in nonverbal and symbolic forms.
  • Spatial ability requires representation, rotation, and inversion of objects in 3D when they are presented in 2D.
examples of the importance and uses of spatial ability
Examples of the Importance and Uses of Spatial Ability
  • Mathematicians visualize mathematical relationships
  • Database structure, Information visualization
  • Physical scientists visualize models of the physical world
  • Diagrams and drawings
  • Solving algebraic word problems
  • Searching for numerical patterns
  • Graphing
  • Conceptualizing mathematical functions

two reasons for the report
Two Reasons for the Report
  • Long term prosperity of our Nation will increasingly rely on talented and motivated individuals who will comprise the vanguard of scientific and technological innovation.
  • Every student in the U.S. deserves the opportunity to achieve at his or her full potential.
statistics

  • Internet perceptions
  • Study approaches
  • Age
  • Gender
  • (Ford, et al. , 2001)
relevance
Relevance
  • The information retrieved was judged to be relevant if it was written for the employer.
  • If the information was about the injury from an employee perspective, it was judged to be not relevant.
retrieval effectiveness linked to
Retrieval effectiveness linked to
  • Male gender
  • Low cognitive complexity
  • Imager as opposed to verbalizer

nature or nurture
Nature or Nurture?

“It may be that even high achieving females now studying IT may be encumbered by the effects of biased training and education in their primary and secondary education of some years ago.”

Ford, et al. (2001), p. 1061

revising the visualizer verbalizer dimension
Revising the Visualizer-Verbalizer Dimension
  • Kozhevnikov, Hegarty, & Mayer. (2002) Revising the visualizer-verbalizer dimension: Evidence for two types of visualizers.
visual vs spatial imagery
Visual vs. Spatial Imagery
  • Visual imagery – representation of a visual appearance of an object
  • Spatial imagery – representation of the spatial relationship between parts of an object, the location of an object in space, and their movements and not limited to the visual modality (could be auditory or tactile)
visualizer verbalizer
Visualizer-Verbalizer
  • Visualizers with high spatial ability (spatial type) – High spatial
  • Visualizers with low spatial ability (iconic type) – – High visual, low spatial
  • Verbalizers
visualizers with low spatial ability
Visualizers with Low Spatial Ability
  • Visual artists have higher scores on visual memory tests than people with high spatial ability
  • May need help interpreting graphs because people with low spatial ability interpret graphs more literally
field independence
Field-independence
  • Connections between spatial ability and field-independence

mental rotations test
Mental Rotations Test
  • Unlike most spatial ability tests, the MRT does not correlate well to any tests of verbal ability. It is a true spatial test.

Vandenberg & Kuse, 1978

mental rotation sat m
Mental Rotation & SAT M
  • Significant relationship between mental rotation skills and SAT Mathematics scores for females (between .35 and .38)

Nuttall, Casey, & Pezaris, 2005

  • Skill in mental rotation can significantly predict SAT-M performance

individual differences in human computer interaction
Individual Differences in Human-Computer Interaction
  • Egan, D.E. (1988)
  • “Differences among people usually account for much more variability in performance than differences in system designs or differences in training procedures.”
3 rd quartile to 1st quartile compared
3rdQuartile to 1st Quartile Compared
  • Text Editing – 2:1
  • Programming – 6:1, 5:1, 4:1, 3:1, 2:1
  • Information Search – 2:1, 3:1, 4:1
  • Comparing 1st Quartile to the 4th Quartile, the range difference is even greater, as much as 30:1 for programming
predictors of difference in performance egan 1988
Predictors of Difference in Performance (Egan, 1988)
  • Experience – Often the most powerful predictor of performance
  • Some differences may be a part of selection artifact, experts begin as good students and build on positive experiences
