Streszczenie:
We examined user behavior on information search
tasks at two levels of complexity. Users were divided
into two levels of 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
and switched their search tactic by significantly
decreasing individual documents they visited.
