Usage de la tablette tactile par les personnes âgées : une approche écologique de l'évaluation et de l'aide à l'apprentissage

Abstract : In modern society, use of information and communication technologies (ICTs) is critical in order to avoid exclusion from many common modern day activities. Furthermore, longer life expectancy presents a major challenge to support dependent seniors, or those at risk of losing their independence but wish to continue living in their own home. ICTs seem particularly relevant in this context. Indeed, they promote social engagement, facilitate access to social networks, and provide a gateway to a wide range of information. Of particular interest in the present study are landline or mobile phones, and tablet computers, which are more readily portable, offer simpler functionality than most computers, and therefore are potentially very useful for aging people, included people with neurocognitive disorders. Broadly, such ICTs help to maintain and improve autonomy. Despite these potential benefits, seniors do not commonly use ICTs. Age-related physical and cognitive decline may affect the ability of older people to use ICTs. Therefore, it is essential to promote education and learning. However, an adapted and effective support could not exist without a fine evaluation of the nature of the difficulties and of the efficient cues. Consequently, we wanted to study the particular difficulties of older people in using these technologies, but also the conditions of the assistance they can benefit from. The objectif of this thesis project was to determine whether elderly encountered specific difficulties in using new ICT, in order to offert them an adapted support. A performance-based assessment and a comparison of the capacity of ICT ise of young and old adults has shown that older adults are characterized by a greater number of commission errors and a need for more precise and explicit cues, especially for the use of mobile technologies. Exploring the link between the nature of errors produced in the use of ICTs and cognitive skills indicated the determinent factor of inhibition abilities as well as episodic memory, in particular the spontaneous recovery process. These abilities were related to commission errors and not to omissions. Structuring the informative environment and automation of some basic procedures essential to the use of ICTs therefore appear as a very probable orientation to alleviate the difficulties of the elderly. Finally, participation in a tablet computer training program using the errorless learning and spaced-retrieval techniques, allowed to improve attitudes towards technologies as well as the performance when they are used.
