ratio between the number of citations in a given year to any item published in that journal in the previous two years and the number of research items published in the same journal in the same two years. IF, widely acknowledged as the standard measure for scientific quality, places great emphasis on current research, favouring fast moving disciplines, while penalising slower moving topics; the ...

Personality research is usually perceived as lying towards the " softer " end of psychological inquiry, seemingly far from the " harder " neural mechanisms, processes, and neurological lesions which are the daily stuff of neuropsychology. As biologically-oriented personality psychologists, however, we have always tried to couch our proposals in brain-behavioural terms and have even offered sugg...

A major issue in cognitive science concerns how phonological, lexical and conceptual knowledge about words is represented in the human brain. Clues for the relevant linguistic categories have been sought in patients with brain lesions and in processing differences for various word categories using positron emission tomography (PET) and electrical brain activity. One useful tool in the physiolog...

Reiser directs his message to workers at opposite ends of the behavioral spectrum: biologists and analysts. For many of the readers trained in the "biopsychosocial" era, however, Dr. Reiser's conceptual thrust may fall on already sensitized ears. Considering its massive scope, the book is of modest length. It raises more questions than it answers. And with his emphasis on heuristic value, one m...

Neuropsychology includes both the psychiatric manifestations of neurological illness (primary brain-based disorders) and neurobiology of "idiopathic" psychiatric disorders. Neurological primary brain disorders provoke broad spectrum of brain pathophysiology that cause deficit sin human behaviour, and the magnitude of neurobehavioral-related problems is a world wide health concern. Speech disord...

Specific learning disabilities are a class of disorders that arise from neurodevelopmental abnormalities. The social–emotional processing disorder (SEPD), which has also been referred to as the non-verbal learning disability and the right-hemisphere learning disability, is a syndrome thought to arise from congenitally or early acquired damage to the right hemisphere.1 It is characterized by a h...

This special issue of the Archives of Clinical Neuropsychology was created to honor Ralph Reitan and his accomplishments. His death marks the end of an era in clinical neuropsychology and the loss of a major neuroscientist and psychologist. It has been said with good reason that Reitan is the founder of clinical neuropsychology, and his long career extended from its birth to the present period ...

structure. All three groups displayed negative transfer to random material in block 7, and positive transfer to block 8, which is constructed as blocks 1–6. The crucial test of transfer involves new material with different surface structure but the same abstract structure in blocks 9 and 10. The schizophrenic group showed no evidence of use of the abstract information in blocks 9 and 10, as was...

Recent neuroimaging studies have provided evidence for localized perceptual speci®city in the processing of human voice stimuli, paralleling the speci®city for human faces. This study attempted to delineate the perceptual features of human voices yielding selective processing, and to characterize its time-course. Electrophysiological recordings revealed a positive potential peaking at 320 ms po...
