Toward a Computational Neuropsychology of Cognitive Flexibility

Computational and neurobiological mechanisms underlying cognitive flexibility.

The ability to switch between multiple tasks is central to flexible behavior. Although switching between tasks is readily accomplished, a well established consequence of task switching (TS) is behavioral slowing. The source of this switch cost and the contribution of cognitive control to its resolution remain highly controversial. Here, we tested whether proactive interference arising from memo...

Introduction to special issue on computational modelling in cognitive neuropsychology.

Recently, Cognitive Neuropsychology altered the statement of the journal’s aims that appears in every issue, the new material expressing an interest in publishing “computational modelling research that is informed by consideration of neuropsychological phenomena”. The journal’s interest in computational models, however, is anything but recent. When Cognitive Neuropsychology was in its first dec...

Cognitive Neuropsychology

Parts of the left ventral visual pathway are engaged selectively during the perception of words, letterstrings, and even single letters. While studies have shown overlap between activations for letters and characters across writing systems, they adopted group analyses with very limited spatial resolution, or used words and letterstrings, which have been shown to activate different regions from ...

Cognitive Neuropsychology and Computational Modelling: The Contribution of Computational Neuroscience to Understanding the Mind

Towards a computational neuropsychology of action.

From a computational perspective, the act of using a tool and making a movement involves solving three kinds of problems: we need to learn the costs that are associated with our actions as well as the rewards that we may experience at various sensory states. We need to learn how our motor commands produce changes in things that we can sense. Finally, we must learn how to actually produce the mo...
