English abstract

Assessing cognitive load on web search is useful in examining which search system features, search tasks types and phases are more cognitively difficult for the searchers. It is also helpful in examining how individual differences among searchers (e.g. cognitive abilities) affect the search process. This investigation examined cognitive load from the perspective of primary and secondary task performance. A controlled web search study was conducted with 48 participants. The primary task performance components were found to be significantly related to the subjective task difficulty. However, the relationship between subjective task difficulty and the secondary task performance measures was weaker than expected. The results indicate that the dual-task approach needs to be used with caution.
