Effects of working memory capacity on users' search effort
Jacek Gwizdka · 2013
We examined user behavior on information search tasks at two levels of complexity. Users were divided into two groups according to their working memory span (WM). The results show that in more demanding task conditions both user groups change behavior, but they differ in how they change it. High-WM user performed more actions to find more information, while low-WM users changed their behavior by significantly decreasing the number of documents they visited.
