Assessing Web interaction with recollection: Age-related and task-related differences

The current study examined how young (n = 26; mean = 22.31 years) and older Internet users (n = 24; mean = 64.54 years) performed when they had to select and recollect information displayed in Web pages. Content-oriented and navigation-oriented information-finding tasks were used during the study phase. At test, the method made use of two recognition paradigms designed to assess recollection and the nature of representations in memory: namely, the remember/know procedure and a forced-choice recognition procedure which made it possible to compare the retrieval of detailed (verbatim-based) and semantic (gist-based) representations. The evidence from both procedures suggested that remembering was less contextualised in older participants. Furthermore, the idea that content-oriented searches impose greater processing demands than navigation-oriented searches in Web pages was confirmed for both age groups. Interestingly, the older Internet users experienced more difficulties in finding targets in navigation-oriented searches than in content-oriented searches. (C) 2011 Elsevier Ltd. All rights reserved.
