| الوصف: | The ability to flexibly adapt behavior in the light of changing contextual demands is crucial for successful goal pursuit. With age, children become increasingly able to flexibly switch between tasks but show poorer switching performance even in late childhood. Given the crucial role of cognitive flexibility in daily life, such as the ability to shift to a new strategy to solve a problem when the previous one did not work, studies have aimed to improve cognitive flexibility with training in children. A key question for the effectiveness of these interventions is understanding why children show lower cognitive flexibility than adults. In this dissertation, I shed new light on this question, by investigating 8–11-year-old children using behavioral measures in combination with measures of univariate activation, multivariate decoding, and task-related connectivity based on data from functional magnetic resonance imaging (fMRI). In Papers 1 & 2, I first addressed the question of which neural processes support the development of cognitive flexibility. In Paper 3, I examined how these neural processes change with training. I have prefaced the three papers with a synopsis in which I outline the theoretical framework of the dissertation and summarize the current empirical findings. Finally, I summarize the results of the empirical part of this dissertation and discuss their contribution to our understanding of the development of cognitive flexibility. Flexibly switching between tasks comes at a cost, evident in decreased accuracy and increased response times. Specifically, compared to performing single tasks in isolation, task switching poses greater demands on maintaining and managing multiple task sets, thus eliciting so-called mixing costs. Additionally, a switch to a different task compared to a repetition of the same one requires the inhibition of the previously relevant task set and updating the newly relevant one, resulting in so-called switch costs. Previous research has demonstrated that mixing and switch ... |
