Title: |
Task Demands and Memory
in Web Interaction |
|
Aim: |
To explore the effects of different web tasks
(locating a link, finding specific facts or dispersed information in a web
site) on information retrieval performance and memory in web interaction. |

Project
description |
While looking for information in a web site, web
elements that are processed differently acquire different statuses in memory
(Oulasvirta, 2004; Oulasvirta et al., 2005). According to the “levels of
processing” theory (Craik and Lockhart, 1972; Lockhart, 2002) memory for web
elements that are deeply processed should be better. The way information is processed and remembered
depends on the task demands. Content-oriented tasks (i.e. finding information
about a topic) demand deeper processing than navigation orientation tasks
(i.e. finding a link). In this project we propose to explore this issue by
measuring memory and task performance as a function of the level of
processing imposed by the tasks (locating a link, finding specific facts or
dispersed information in a web site). Furthermore, the dual task paradigm
will be used in order to measure the levels of processing for the different
web tasks used. |
