Campagnoni & Ehrlich Study
Results, continued
- Found a strong correlation between visualization ability and search time.
- Interestingly, most of the extra time seemed to be spent by the poorer visualizers in returning to the top level node rather than just going up one level
Commentary
- The study is flawed by not allowing query formulation
- Also, should test conditions in which users forced to use analytic vs browsing, rather than just observing their choices.
