These differences have led to It has been long recognized that individuals with aphasia have considerable debate about the nature of the functional deficits of lexical processing impairments. Particular focus has been on the these individuals and their underlying neurobiological substrates. two classical clinical types, Broca’s and Wernicke’s aphasia, with Given that word recognition calls on many different aspects of the goal of understanding the neurobiological substrates of word cognitive processing, impairments of any of these aspects could recognition.

  • Neuropsychologica the Past and Future of Neuropsychology
    REVIEW ARTICLE ACTA Vol. 4, No. 1/2, 2006, 1-12 NEUROPSYCHOLOGICA THE PAST AND FUTURE OF NEUROPSYCHOLOGY J.M. Glozman Moscow State University, Moscow, Russia Key words: locationalism, anti-locationalism, dynamic brain systems, Lurian neuropsychology SUMMARY The history of neuropsychology can be conceived in three conceptually and chronologically overlapping phases. The first phase, dominated by the dialectic between locationism and holism (antilocationism), focused on reduc- ing the human mind to the activity of neural processors (locationism), or of the brain as a whole (holism). In the second phase, marked by the introduction of Luria's concept of dynamic systems, mind is derived from the interaction of dynamic neural systems, whose components are dispersed both horizontally and vertically, and the concept of syndrome becomes prominent. In the third phase, neuropsychologists have begun to look at the brain as part of a whole human being, who lives in a particular ecosphere and comes into contact with other human beings. This last phase, which also draws inspiration from Luria's work, has pushed neuropsychology into new fields of inquiry, such as per- sonality and family dynamics. It has also been marked by a shift from product- based to process-based neuropsychology, and the emergence of quality of life as a goal and outcome measure in neuropsychological rehabilitation. INTRODUCTION All over the world contemporary neuropsychology is demonstrating a gene- ral tendency to replace state-based neuropsychology, which relates the brain- damaged individual's symptoms to the precise location of cerebral lesions, with a more dynamic, process-based neuropsychology, which analyzes the dynamics of the brain-behavior interaction (Tupper & Cicerone 1990, Glozman 1999a).

  • Cognition and Aphasia: a Discussion and a Study
    Journal of Communication Disorders 35 22002) 171±186 Cognition and aphasia: a discussion and a study Nancy Helm-Estabrooks* Harold Goodglass Aphasia Research Center Ð 12A, Boston Veterans Administration Medical Center, Boston University School ofMedicine, 150 South Huntington Avenue, Boston, MA 02130, USA Received 23 October 2001; received in revised form 18 December 2001; accepted 18 December 2001 Abstract The relation between other aspects of cognition and language status of individuals with aphasia is not well-established, although there is some evidence that integrity of non- linguistic skills of attention, memory, executive function and visuospatial skills can not be predicted on the basis of aphasia severity. At the same time, there is a growing realization among rehabilitation specialists, based on clinical experience and preliminary studies, that all domains of cognition are important to aphasia therapy outcomes. This paper describes a new study of the relation between linguistic and nonlinguistic skill in a group of individuals with aphasia. No signi®cant relationship was found between linguistic and nonlinguistic skills, and between nonlinguistic skills and age, education or time post onset. Instead, individual pro®les of strengths and weaknesses were found. The implications of these ®ndings for management of aphasia patients is discussed. Learning outcomes: Readers of this papers will be able to: list ®ve primary domains of cognition and relate each to an aspect of aphasia therapy; describe at least three studies that examined the relation between cognition and aphasia; describe four nonlinguistic tasks of cognition that can be used with a wide range of aphasia patients. # 2002 Elsevier Science Inc.
