    Bridging the generational gap: Designing internet services for technologically-naïve older people using familiar interfaces2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Despite advances made in modern electronic devices, their use by older people is significantly lower than for younger people. They experience difficulties using devices due to a combination of physical, cognitive and ‘generational’ differences. Many studies try to adapt devices to make them more usable, but they do not consider how older people feel in terms of attitudes towards technology or their existing habits. Seven participants were interviewed about their current use of technology, as well as their attitudes to modern technology, and a personal inventory was created for each participant. The interviews generated themes relating to how participants feel that technology is not made for them, barriers to their use, and generational differences as well as arguments against modern technology use and perceived negative aspects of technology. Some design considerations were created and illustrated using features from the most commonly used devices that suited the interviewees’ attitudes, behaviours and opinions.

    Hypertension, Infection and Inflammation and their Effects on Memory and Visuospatial Skills in Ageing2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Blood pressure has previously been associated with decline in memory over time, though the exact mechanism behind this effect is uncertain. Infections, which can lead to systemic inflammation have also been linked to some cardiovascular damage to the brain, known as microbleeds, which have themselves been linked to greater declines in cognition in old age. The present study investigates whether blood pressure, a self-reported history of infection, and an indirect measure of inflammation known as the erythrocyte sedimentation rate have any association with on episodic and semantic memory and visuospatial skills in the Betula study, a Swedish longitudinal population study. The effect of elevated blood pressure (over 140 mm Hg systolic and/or 90 mm Hg diastolic), high blood sedimentation (top 33% against bottom 33% of participants), and self-reported infection were all found to not have any significant effect on episodic memory, semantic memory or visuospatial skills. Some of the possible explanations are elaborated in the discussion.
