This work presents two studies that aim to discover whether age can be used as a suitable metric for distinguishing in performance between individuals, or if other factors can provide a greater insight.Information retrieval tasks are used to test the performance of these factors. First a study is introduced that examines the effect that fluid intelligence and Internet usage has on individuals. Second, a larger study is reported on that examines a collection of Internet and cognitive factors in order to determine to what extent each of these metrics can account for disorientation in users.This work adds to growing evidence showing that age is not a suitable metric to distinguish between individuals within the field of human computer interaction. It shows that factors such as previous Internet experience and fluid based cognitive abilities can be used to gain a better insight into users’ reported browsing experience during information retrieval tasks.
