Abstract
  • Vertical search in Information Retrieval (IR) represents display opportunities for searcher interaction in the form of blended and non-blended results. Search behavior and preference in interacting with these results can be influenced by both design and personal, cognitive abilities. This study evaluates the relationship between cognitive ability and vertical search behavior and preference. In this lab study cognitive tests measuring perceptual speed and visual memory were administered to sixteen participants who subsequently performed four search tasks on two search engines, one with a blended display and one with a non-blended display. Cognitive tests, search logs and participant questionnaires were used to evaluate vertical search behavior and preference in cognitively high and low performers. The findings suggest that cognitive ability influences vertical search engagement and preference. The value in this research is its ability to contribute to issues of result merging, display, and interaction at a personal level in vertical search.
