Abstract
Some research results have
documented the phenomenon that
interactivity of media helped improving
human information processing. That is,
when people have control on information
they acquire, their information processing
performance is enhanced (Klayman, 1988;
Kuhn & Ho, 1980; Ariely, 2000). On the
Internet, there are two ways of information
control, “push“ and “pull”, which provides
higher information control for people than
the former. Does this imply that the “pull”
way of information control will affect
human information processing more
positively than the “push” way? If it is so,
is the effect similar for people with
different degree of expertise on the
information they process?
As suggested by prevalent research results of cognitive psychology: people actively
bring out the information stored in
memory when they process new
information at hand (Chase & Simon,
1973; Kahneman & Tversky, 1972). If the
knowledge of the information searcher is
not enough to lead his/her attention to
focus on relevant information, then the
“pull” way of control would not be as
effective as used by experts. When experts
are given freedom to search information at
their own choice, they are more efficient
in search information because they focus
their attention on relevant information. On
the other, when information searcher does
not have enough knowledge to be on the
right track, the “push” way might be
useful to “push” the relevant information
into his/her attention and hopefully, further
onto deeper processing, such as memory.
In another word, the effect of different
degrees of information control inherited in
“pull” and “push” on the Internet could be
different for people with different
expertise. For further investigation on this
issue, this research proposal is offered.
