Cognitive psychologists investigate processes using case studies of brain-damaged patients, these are then analysed to build models that represent normal cognitive processes. This essay will examine the contribution case studies have made to the development of cognitive neuropsychology as a discipline in its own right and draw attention to issues surrounding the use of brain damaged patients to infer cognitive functions and processes. At the same time, it will evaluate the contribution that case studies have made to our understanding of cognitive processes.
Cognitive processes are the unseen systems used by our minds to complete tasks such as solving problems, recognising an object, or learning a language. These unseen mental processes take place in the brain, which is a complex piece of equipment often compared to a computer.

- Brain Damage and Behavior The history of modern neurology, neuropsychology, and related disciplines is closely associated with the theory that different parts of the brain serve different functions (Finger, 1994). During experimentation scientist discovered relatively three common causes that lead to brain damage. Lesions are one of these contributors to brain damage; a lesion is an obstruction to an organ or tissue that has been inflicted via tumor, physical head trauma, or injury.

- Conflict and Resolution in Herbert's Discipline George Herbert’s struggle to be humble enough to fully accept God’s undying love can be located within each of his poems.
