A research initiative as well as a doctoral program in developmental cognitive neuroscience has been developed in the Department of Psychology at the University of Houston. Developmental cognitive neuroscience can be defined as the study of cognitive processes and their neurological bases in the developing organism. Researchers in this area are attempting to understand the development of such cognitive processes as perception, speech, language, reading, attention, thinking, memory, and emotions. They are using the latest imaging, electrophysiological, and neurochemical techniques to determine the neural correlates of these processes. Animal models are also employed by some of these researchers to further our understanding of the developing brain and disorders of development.
Internationally there continues to be an emphasis on neuroscience research that culminated in the Decade of the Brain in the United States in the 1990s. There is no sign of this emphasis abating. Indeed, it would be difficult to find a major research university or medical school without a neuroscience initiative that is multi-disciplinary in nature. There appears to be an increased emphasis politically and in the health care system on child health and development. As a result, there are tremendous funding opportunities for researchers in developmental cognitive neuroscience. For instance, the National Institute of Neurological Disorders and Stroke (NINDS) and the National Institute of Child Health and Human Development (NICHD) have set up a joint committee to review grant applications involving research with children. NINDS and NICHD are currently inviting exploratory/developmental research grant applications to facilitate the translation of fundamental neurobiology to pediatric brain disorders of anomalous development, neurodegeneration, and injury with emphasis on cross-discipline collaborations, novel hypotheses, and unique approaches. This research is so important. Assumptions are sometimes made about the developing organism that are both incorrect and disastrous for children. For instance, it was a long-held belief in the clinical community that the consequences of a brain injury were less serious for children than adults because the child's brain is more plastic and adapts more easily. On the basis of this belief policy makers even argued that car seats for children need not be mandatory since they would recover better from brain damage. We now know that this belief was incorrect, that damage to the developing organism may prevent cognitive processes that should develop at later stages from developing normally and that the consequences are sometimes more serious in the long term. While cognitive processes and their neural underpinnings need to be understood in children in order to facilitate their development, such research can also help adults. For instance, adults who have difficulty with cognitive processing may benefit from strategies derived from our understanding of how these processes develop normally in children. We intend to take a life-span approach to many of the problems investigated.
Positions for well-trained individuals in developmental cognitive neuroscience are likely to continue to be available in academic departments of psychology and education as well as in medical schools and other research facilities.
The University of Houston is a recognized leader internationally in the education and training of clinical neuropsychologists as well as individuals in the subspecialty of clinical child neuropsychology. This is in large part because of the resources already available in the Department of Psychology and the Texas Medical Center in terms of research programs and practicum experiences with individuals throughout the lifespan (ie., babies, children, adolescents, and adults). There is perhaps one of the largest concentrations of neuropsychologists having research and clinical interests in developmental cognitive neuroscience in the country. Quite a few of these individuals have an international reputation for scholarship and have been very successful in attracting external funding, for instance, from the National Institutes of Health, the Centers for Disease Control, and the National Science Foundation.
Developmental cognitive neuroscience would bring together under one research initiative clinical neuropsychologists, cognitive psychologists, developmental psychologists, statisticians, engineers, and physicians, for instance. This initiative would give them access to graduate students seeking research training in this area and potentially should lead to more extensive collaborations with program affiliated faculty. Collaborations with individuals at the University of Texas – Houston Health Sciences Center, Baylor College of Medicine are already well established. Additionally, collaborations with the cognitive psychology program at Rice University could result as well as collaborations with individuals in other departments at the University of Houston.
The addition of several key individuals with a theoretical approach to the study of developmental aspects of cognition as related to the developing nervous system will increase our national and international prominence in this area. Excellence funding from the State of Texas is being used to hire new faculty.
