In broad outline my research aims to understand the neural and neuromodular underpinnings of cognitive control in humans. This involves the investigation of all kinds of factors that might predict, impair, or enhance people’s control abilities, such genetic disposition, videogame practice, drug use, stress, emotions, intelligence, working memory capacity, hormones, bilingualism, dopaminergic baseline levels, or religious belief. Combining a cognitive neuroscience perspective with a focus on individual differences, I study, by means of a wide range of computerized tasks, whether and how cognitive control processes and their neurobiological mechanisms are affected by these factors. A central theme in this research is how different aspects and subsystems of cognitive control (such as maintenance and flexibility, top-down bias and inhibition) can be disentangled and how the underlying processes interact to regulate thought and action. Given the importance of dopamine in this regulation, I have a strong focus on neuromodulation, which seems to be responsible for the dynamics of human cognition and the adaptivity of cognitive control.
