Viceversa, a well designed website interface may simplify the access to
information and reduce both ambiguity and uncertainty. Time
needed to search for information also affects the amount of cognitive
cost the user has to bear in the interaction with the website. The
more the user has to think about how to use the website interface,
the less a sufficient amount of cognitive and perceptual resources
will be available to perform the main task. Time perception is thus
associated to mental workload (Baldauf et al., 2009). A lower
amount of time consumed to achieve a task is usually associated to
more efficient information processing and effective website design.
