Locating NREM Dreaming Through Instrumental Responses
Psychophysiology - Tập 15 Số 1 - Trang 35-39 - 1978
Judith N. Brown, Rosalind Cartwright
ABSTRACTOne difficulty associated with the study of dreams has been the absence of an objective indicator of dreaming in sleep other than REM. This study explores the use of a subjective judgment and instrumental response to mark the occurrence of dreams. Content reports of 8 subjects collected under two conditions were compared. On 2 nights the experimenter determ...... hiện toàn bộ
The time course of pupil dilation evoked by visual sexual stimuli: Exploring the underlying ANS mechanisms
Psychophysiology - Tập 54 Số 10 - Trang 1444-1458 - 2017
Johannes B. Finke, Christian Eric Deuter, Xenia Hengesch, Hartmut Schächinger
AbstractThe early processing of visual sexual stimuli shows signs of automaticity. Moreover, there is evidence for sex‐specific patterns in cognitive and physiological responding to erotica. However, little is known about the time course of rapid pupillary responses to sexual stimuli and their correspondence with other measures of autonomic activity in women and me...... hiện toàn bộ
The pupil as a measure of emotional arousal and autonomic activation
Psychophysiology - Tập 45 Số 4 - Trang 602-607 - 2008
Margaret M. Bradley, Laura Miccoli, Miguel A. Escrig, Peter J. Lang
AbstractPupil diameter was monitored during picture viewing to assess effects of hedonic valence and emotional arousal on pupillary responses. Autonomic activity (heart rate and skin conductance) was concurrently measured to determine whether pupillary changes are mediated by parasympathetic or sympathetic activation. Following an initial light reflex, pupillary ch...... hiện toàn bộ
Pupil dilation indicates the coding of past prediction errors: Evidence for attentional learning theory

Significance Testing of Difference Potentials
Psychophysiology - Tập 28 Số 2 - Trang 240-244 - 1991
Donald Guthrie, Jennifer S. Buchwald
ABSTRACTThis note provides a statistical‐graphical method for the evaluation of the statistical significance of difference potentials from a group of subjects, and for the comparison of difference potentials between two groups. A table of the lengths of statistically significant intervals for various sampling interval lengths, numbers of subjects, and autocorrelati...
The Continuing Problem of False Positives in Repeated Measures ANOVA in Psychophysiology: A Multivariate Solution
Psychophysiology - Tập 24 Số 4 - Trang 479-486 - 1987
Michael W. Vasey, Julian F. Thayer
ABSTRACTViolation of the validity assumptions of repeated measures analysis of variance continues to be a problem in psychophysiology. Such violation results in positive bias for those tests involving the repeated measures factor(s), Recently it has been shown that the tests of simple interactions and multiple comparisons are even more vulnerable to bias (Boik. 198...... hiện toàn bộ
Aging and the Simon task
Psychophysiology - Tập 39 Số 1 - Trang 100-110 - 2002
Rob H. J. van der Lubbe, Rolf Verleger
A visual Simon task was used to study the influence of aging on visuospatial attention and inhibitory control processes. Responses were much slower for elderly than for young participants. The delay in trials in which stimulus and response side did not correspond as compared to when they did correspond (the Simon effect) was larger for older people, even after correcting for general slowin...... hiện toàn bộ
Influence of caffeine on selective attention in well‐rested and fatigued subjects
Psychophysiology - Tập 31 Số 6 - Trang 525-534 - 1994
Monicque M. Lorist, J. Snel, Albert Kok, G. Mulder
AbstractEffects of caffeine were studied in a visual focused selective search task in well‐rested and fatigued subjects. A dose of 200 + 50 mg caffeine or placebo, dissolved in decaffeinated coffee, was administered in a double‐blind and deceptive fashion. The task was to detect a target letter on one diagonal of a visual display designated as relevant and ignore s...... hiện toàn bộ

THE FIRST NIGHT EFFECT: AN EEG STUDYOF SLEEP
Psychophysiology - Tập 2 Số 3 - Trang 263-266 - 1966
H. W. Agnew, Wilse B. Webb, Robert L. Williams
ABSTRACTThe electroencephalographic records from 43 subjects who slept for four consecutive nights in a laboratory environment were studied in an effort to describe the First Night Effect. These records showed that the first night of laboratory sleep contains more awake periods and less Stage I‐rapid eye movement sleep. There is a delay in the onset of Stages IV an...... hiện toàn bộ
