Clinical and experimental approaches to varieties of memory

Abstract

Memory is described as a complex aspect of cognitive functioning. Memory is dependent upon input from the sensory modalities; it relies upon the passage of time; and it requires intervening processes for initial acquisition and subsequent access. Based upon questions posed concerning the relationship between clinical and experimental advances in memory and memory disorders, an example is given to illustrate the influence of research upon techniques for diagnosis and rehabilitation. Suggestions are provided about how to approach answering other related questions in neuropsychology. An integrated program is suggested with the aim of bringing together findings from neuroanatomy, neurochemistry, and neurobehavior. Emphasis is placed upon integrating results of research based upon human and nonhuman models of disordered memory and other cognitive functions. Neuroanatomical systems important for performing delayed-reaction tasks are reviewed, as are results of delayed response and delayed alternation testing in several human populations with neurological dysfunction suggestive of frontal lobe damage.
