Cognitive psychology is the study of the brains internal processes that guide behaviour; to study cognition, psychologists examine case studies of patients with damaged brains that can infer areas, and functions involved in particular processes. Patient studies have provided insights into the processes that take place within our minds, and have enabled psychologists to create models, which can be tested and fractionated. Cognitive neuropsychology has developed from cognitive psychology to become a discipline in its own right; it investigates the function and structures of the brain involved in cognitive processes and should not be confused with cognitive neuroscience, which is primarily concerned with neural structures and their functions.
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. When the internal workings of a computer are exposed, all that we see are microchips, circuit boards, hard drives and other assorted pieces, which, all work and ...

One of the major differences between humans and animals is our ability to reason and differentiate our actions from our instincts (Barrett, 2011, p. 3). Justin Barrett further explains this distinction in the first chapter of his book, Cognitive Science Religion and Theology. He explains that cognitive science recognizes the uniqueness of the human mind and focuses on explaining the thinking processes that take place(Barrett, 2011, p. 5). This may seem similar to what the field of neuroscience aims to do but, cognitive science is not as interested with the biological functions of the brain. Instead of looking at physical structures Barrett writes, that cognitive science focuses on broader processes such as perception, attention, memory, reasoning and learning (Barrett, 2011, p. 7). All of these processes interact with each other to create the big questions asked in cognitive science. Some of these big underlying questions of cognitive science are explored in this first chapter, questions such as “What is innate?” or “How are mind and bodies
I intend to explore the effects of a parietal brain injury from the perspective of a neuropsychologist; ranging from types of tests that are employed when trying to determine the extent of the damage, to gaining an understanding of how this damage will affect the rest of the brain and/or the body. I will also explore the effects of a brain injury from the perspective of the family members, and their experiences with the changes that occur during the rehabilitation process. According to The Neuropsychology Center, “neuropsychological assessment is a systematic clinical diagnostic procedure used to determine the extent of any possible behavioral deficits following diagnosed or suspected brain injury”(www.neuropsych.com). As mentioned previously, a brain injury can be the result of many types of injuries or disorders, thus a broad range of assessment procedures have been developed to encompass these possibilities.

Cognitive perspective is the thought and storing processing of the brain. It also consists of remembering, using, and learning information. In addition to this perspective, within it is cognitive neuroscience which deals with the living brain’s activity and imaging its structure.
