Examining task demands in web interaction and age differences through episodic memory

Published: 28 August 2007 Publication History

Abstract

Motivation -- Relying on the sensitivity of memory measures to the depth of processing in a prior episode could provide a means of analysing how information is processed during Web interaction (Oulasvirta, 2004). This strategy is applied in order to examine task-related differences in Web information search activity as a function of age.
Research approach -- 26 "young" participants (mean=22.31 years) and 24 "old" participants (mean=64.54 years) accomplished several information finding tasks on Web pages in two conditions: navigation--orientation and content--orientation. Afterwards, they carried out two recognition tests.
Findings/Design -- Overall, the data indicated that the older adults performed at lower levels than the young participants for navigational search. Also, they had difficulty in recollecting episodic information concerning previously viewed Web pages, as revealed by two memory dissociations.
Originality/Value -- Experimental investigation of dual-memory processes (recollection vs. familiarity; verbatim vs. gist-based representations) lead to more sensitive measures of task-related differences and age differences than correct recognition memory performance.
Take away message -- Episodic memory measures can give an account for variations in task requirements and age-related differences in Web interaction.
