The effects of arousal and attention on central, autonomic and behavioral processes 1971 870 The present investigation was conducted primarily to clarify further the dissociative and associative effects of arousal and attention on the evoked cortical potential (ECP), contingent negative variation (CNV), heart rate (HR), and reaction time (RT...
Arousal level and voluntary alpha control 1977 55 To examine the influence of arousal level on subjects' ability to voluntarily control alpha activity level, loud unpleasant noises were presented at random intervals. The effect of this aversive stimulus situation on alpha activity level relative to ...
Evoked potentials to syllable perception and production 1977 41 The purpose of this study was to devise and test a methodology to investigate cortical activity during speech perception and production that eliminates some of the confounding variables that have existed in previous research, such as the variability ...
Attention-related evoked potential correlates of precortical gating in the human visual system 1987 9 The precortical gating hypothesis was tested by having subjects selectively attend to points in space under conditions wherein the saliency (size) of the evoking stimulus and motivation level of subjects were manipulated in an attempt to further eluc...
The influence of sensory and motor set on early attention-sensitive VERs 1987 6 The study examined whether motor set, along with perceptual set, produces precortical short-latency poststimulus effects in the visuo-motor system. Eighteen subjects participated in a spatial selective attention paradigm developed by Eason, Harter, a...
Visual-spatial selective attention and reading ability in children : a study using event-related potentials and behavioral measures 1991 4 Reading-disabled subjects have shown a pattern of visual-perceptual processing which is consistent with a deficit in the pathway that encodes transient visual information. Given that this processing stream appears to mediate spatial information, it w...
The effects of arrow direction, length of interstimulus interval, and certainty of interstimulus interval length on event related potentials occurring during the course of the interstimulus interval 1995 1 This study examined the electrophysiological correlates of the preparatory processes intervening between the presentation of an attention-directing arrow cue and the presentation of a target stimulus. A paradigm used in earlier studies by Harter and ...
