“…Two retrieval interfaces were used which were validated, one as a high-complexity and the other as a low-complexity retrieval system for seniors (see, Nap et al, 2005;Nap, 2008). In that study, stress was observed when seniors performed search tasks on the high-complexity system, while no stress was observed when seniors performed search tasks on the low-complexity system.…”

“…Several scholars suggested that stress affects, and is affected by, interface use (Hamborg and Grief, 2003;Hawthorn, 2000). In particular, older users could be negatively affected by stress during computer interaction (see, Hawthorn, 2000;Nap et al, 2005), yet empirical evidence is lacking. It is still unclear which mechanisms play a role in stress during computer interaction.…”

“…Aging affects general changes (declines) in perception, cognition and movement control, which have an influence on learning and using digitised systems (Morrell et al, 2002;Neerincx et al, 2000;Xie, 2002). Seniors have been found to be slower than young adults on information retrieval tasks (Freudenthal, 2001;Nap, De Greef, and Bouwhuis, 2005), on 3D navigation using desktop systems (Sayers, 2004), and on web navigation (Neerincx et al, 2000). Not having access to or not being able to use digitised systems may put older adults at a disadvantage in terms of their ability to live independently (Czaja and Lee, 2007).…”

Self-efficacy of seniors could be negatively affected by stress during computer interaction, yet, empirical evidence is lacking. In an experiment, seniors performed tasks on low-and high-complexity search systems. Self-efficacy was manipulated by performance feedback. Results demonstrate that negative feedback increases stress and decreases self-efficacy. Furthermore, positive feedback increases seniors' self-efficacy during computer interaction and a significant effect was found of self-efficacy on stress. Perceived stress increased with decreasing self-efficacy. System complexity influenced self-efficacy; yet, no relation was found between system complexity and stress. To increase self-efficacy and to decrease stress in senior-computer interaction, it is advised to support seniors during computer interaction with positive performance feedback.

Purpose -The purpose of this paper is to identify demographic differences based on how users interact with web applications. The research is needed to develop future systems able to adapt the representation of online information to the user's specific needs and preferences improving its usability. The following question guides this quest: is there a direct relationship between age and/or gender and interaction? Design/methodology/approach -GOMS (goals, operators, methods, and selection rules) analysis was used to reduce complex interaction tasks into basic operators like pointing, dragging, typing, etc. An experiment was designed to analyse the user performance in the use of these operators through five complex tasks: point-and-click, drag-and-drop, text selection, text edition and menu selection. The sample comprises 592 individuals which took part in the experiment. The performance was analysed using multivariate regression analysis. User laterality and the the user experience were used as control variables. Findings -The factors studied are significant enough to support user classification. The analysis evidenced that men performed significantly better than women when executing interaction pointing and dragging GOMS's operators, but no significant differences arose with regard to the performance in the typing operators. Older users performed worse in all the interaction tasks. No significant performance differences were detected between left and right-handed users.Research limitations/implications -The study pretends to lay the ground for developing artificial intelligence-based classification systems (e.g. neural networks, decision trees, etc.) able to detect significant differences in user performance, classifying users according to their age, gender and laterality. Practical implications -This user profiling would drive the organisation, selection and representation of the online information according to the specific preferences and needs of each user. This would allow the design of new personalisation algorithms able to perform dynamic adaptation of user interfaces in order to improve the usability of online information systems. Originality/value -This work extends previous research on user performance under a new approach and improved accuracy. First, it relies on the combined and simultaneous analysis of ageing and gender and the use of user laterality and experience as control variables. Second, the use of the GOMS analysis allowed the design of tests that closely resemble the user interaction in online
