ERP manifestations of processing printed words at different psycholinguistic levels: time course and scalp distribution.(event-related potential)
May 1, 1999... INTRODUCTION Levels of Processing in Visual Word Recognition Visual word recognition is a complex process that involves several cognitive operations, such as visual encoding of letters, translation of the letters' shapes into a...

Electrophysiological signatures of visual lexical processing: open- and closed-class words.
May 1, 1999... INTRODUCTION In this paper we investigate electrophysiological manifestations of visual lexical processing, as reflected by scalp-recorded event-related brain potentials (ERPs). Our focus is on processes of language comprehension, in...

Patterns of brain activity during visual imagery of letters.
May 1, 1999... INTRODUCTION The brain mechanisms of mental imagery offer an interesting window into understanding cognitive brain functions. One question currently under debate is the degree to which imagery and sensory processing share the same neural...

The neurophysiology of backward visual masking: information analysis.
May 1, 1999... INTRODUCTION Our visual environment is constantly changing. To interact with it in real time we need to rapidly process and interpret visual stimuli. How fast our visual system can do this, and the amount of time needed at each synapse for...

Testing a computational account of category-specific deficits.
May 1, 1999... INTRODUCTION Category-specific deficits are an aspect of semantic memory that have come under considerable attention (e.g., Farah & McClelland, 1991; Gonnerman, Andersen, Devlin, Kempler, & Seidenberg, 1997; Warrington & McCarthy, 1983,...

Accessory stimulus effects on response selection: does arousal speed decision making?
May 1, 1999... INTRODUCTION According to the most popular accounts, the facilitation of voluntary reaction time (RT) by a task-irrelevant stimulus in another modality is due, at least in part, to a brief surge in arousal (Bertelson & Tisseyre, 1969;...

Interview with George A. Ojemann.(professor of Neurological Surgery at the University of Washington in Seattle)(Interview)
May 1, 1999... George A. Ojemann was born in Iowa City, and received undergraduate and medical degrees from the University of Iowa, and his neurosurgical training at the University of Washington in Seattle. He has been on the faculty of that school ever...
