| The effects of arousal and attention on central, autonomic and behavioral processes |
1971 |
1157 |
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... |
| Attention-related evoked potential correlates of precortical gating in the human visual system |
1987 |
223 |
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 |
280 |
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... |
| 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 |
201 |
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 ... |
| The relation between central and peripheral measures in a perceptual-motor task |
1968 |
178 |
A primary purpose of the present investigation was to demonstrate that certain physiological and behavioral variables tend to change concordantly with experimentally-induced changes in activation and to show further that these same variables may be s... |
| The evoked cortical potential and its relation to eye dominance, handedness, and visual field |
1968 |
212 |
Over the years numerous investigators have been concerned with the relationship of the left and right sides of the body. Studies have varied in their focus ranging from sweeping analyses of laterality to more fractionated inquiries of sidedness. The ... |
| The effects of situational anxiety, manifest anxiety and achievement on skin conductance and heart rate |
1969 |
227 |
A primary purpose of the present investigation was to show that an experimental situation requiring relatively little effort on the part of the subjects would be sufficiently arousing to cause concomitant variations in physiological responses. An add... |
| Arousal level and voluntary alpha control |
1977 |
240 |
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 |
226 |
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 ... |
| Visual-spatial selective attention and reading ability in children : a study using event-related potentials and behavioral measures |
1991 |
207 |
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... |
| Electrophysiological indicants of reading disability : a longitudinal investigation |
1991 |
204 |
This study examined the black/white discrimination abilities for letter and non-letter patterns in individuals with and without reading disability using event-related potentials (ERPs) and behavioral measures. ERP and behavioral measures, considered ... |
| Topographical distribution of visually evoked cortical potentials in relation to locus of retinal stimulation and check size |
1971 |
209 |
Visually evoked cortical potentials (VERs) to checkerboard stimulation were studied as a function of locus of retinal stimulation, check size, and relative distribution of response over the cortex. Pattern stimuli of checks subtending 7.5, 15, 30, an... |
| The visually evoked cortical potential : stimulus effects and interactions |
1971 |
231 |
The purpose of this investigation was to obtain parametric data on the effects and interactions of stimulus variables (intensity and size), retinal locus of stimulation and background adaptation level on the visually evoked cortical potential. The su... |
| Retinal processes involved in the evoked cortical potential to patterned stimuli |
1969 |
249 |
The purpose of this investigation was to study the underlying physiological processes involved in the evoked potential to patterned visual stimulation. Specifically, the study was designed to assess the role of the photopic and scotopic visual system... |
| Psychophysiological correlates of voluntary alpha control |
1975 |
180 |
To test the hypothesis that voluntary alpha control is at least partly mediated through self-induced changes in cortical activation level and bodily arousal, changes in several physiological indicants of such activity were systematically examined whi... |
