Abstract: Cognitive training represents an interesting avenue to improve cognitive skills in people of different ages. While the ultimate goal of cognitive training is to transfer knowledge to cognitive processes different from those being trained, such transfer is rarely reported in the scientific literature. In fact, literature reviews indicate that the effectiveness of cognitive training appears to be specific to the training task and that further research is needed to better understand what might contribute to producing far transfer. The present thesis seeks to better understand the factors that contribute to the effectiveness of cognitive training by looking at both the content of the training program and the form that training takes. The thesis focuses firstly on the nature of the cognitive process solicited in the training program and, secondly, on training gamification. A first study concentrates on the process of distractor suppression and examines the impact of training perceptual selection and cognitive control—two distractor suppression mechanisms—on far transfer. The results show that only adaptive training based on these two mechanisms promotes transfer to working memory tasks. The aim of the second study is to isolate the role of game elements in order to target their contribution to cognitive training. This second experiment tests the hypothesis that the use of a scoring system and/or a leaderboard would increase the level of engagement in the training program and promote far transfer. Although the results refute this hypothesis, the presence of these game elements seems nonetheless to be associated with lower attrition rates. These experiments support the idea that the cognitive process being trained and the context in which training is presented each play an important role in the far transfer effect. The thesis offers a new training paradigm that appears to be effective in producing far transfer to the scientific community and highlights the value of exploiting the game elements as a maintenance factor in the repetition of a monotonous task. The thesis envisions an encouraging future where cognitive training could be used to compensate for cognitive deficits present in certain vulnerable populations.
