Professional Differences: A Comparative Study of Visualization Task Performance and Spatial Ability Across...

Area of Science:

• Cognitive Science
• Human-Computer Interaction
• Information Visualization

Background:

• Visualization design often overlooks individual differences in cognitive abilities and personality traits.
• Understanding how domain-specific expertise influences visualization interaction is crucial for effective design.

Purpose of the Study:

• To investigate variations in visualization task performance across different academic domains (chemistry, computer science, education).
• To explore the relationship between cognitive abilities, specifically spatial ability, and visualization task performance.
• To bridge domain-specific visualization needs with cognitive and perceptual factors.

Main Methods:

• An online study involving over 60 domain experts performing tasks with pie charts, isocontour plots, and 3D scatterplots.
• Assessment of visualization task performance (correctness) and correlation with a standardized spatial ability test.
• Analysis of participant confidence and strategy comments to understand engagement nuances.

Main Results:

• Task performance varied significantly by profession for complex visualizations (isocontour plots, 3D scatterplots), but not for pie charts.
• Visualization correctness was found to correlate positively with spatial ability.
• Significant differences in spatial ability were observed among the participating professions.

Conclusions:

• Disciplinary differences extend beyond data and tasks to encompass how effectively individuals engage with visualizations, influenced by cognitive traits.
• Visualization design should consider domain-specific expertise and individual cognitive variations, such as spatial ability.
• Focusing solely on performance metrics neglects crucial aspects of user engagement and strategy, suggesting a need for more nuanced design approaches.
