The ability to modulate behaviour in a goal directed manner, is fundamental to all aspects of life. To become goal directed, attention must be configured to bias perception and action in favour of the current directive. This competitive process allows expansive possibilities to be moulded into coherent purposeful behaviour. It allows intention to become action. The following thesis can be broken down into two parts. The first part is comprised of three empirical chapters that examine the functional consequences and neural underpinnings of impaired attentional control following stroke. The second part is comprised of two empirical chapters aimed at more specific experimental questions. These chapters propose novel paradigms aimed at answering finer grained questions regarding the structure of attentional control. Part I: Chapter 2 examines the functional consequences for patients with impaired attentional control. Chapter 3 takes a subset of patients from the previous chapter and uses a voxel-based lesion-symptom mapping approach to examine damage associated with impaired attentional control. Chapter 4 utilises a BiFactor model to examine whether executive dysfunction manifests differentially after frontal and posterior damage. Part II: Chapter 5 proposes a novel paradigm that allows better dissociation of errors associated with the breakdown of goal directed behaviour. Chapter 6 examines how attention is distributed during concurrent processing and maintenance activities.
