Locating NREM Dreaming Through Instrumental Responses
Psychophysiology - Tập 15 Số 1 - Trang 35-39 - 1978
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 determined the time of
the awakening an...
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
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 men. To study pupil
dilation as an ...
The pupil as a measure of emotional arousal and autonomic activation
Psychophysiology - Tập 45 Số 4 - Trang 602-607 - 2008
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 changes were larger when viewing
em...
Pupil dilation indicates the coding of past prediction errors: Evidence for attentional learning theory
Psychophysiology - Tập 55 Số 4 - 2018
AbstractThe attentional learning theory of Pearce and Hall () predicts more
attention to uncertain cues that have caused a high prediction error in the
past. We examined how the cue‐elicited pupil dilation during associative
learning was linked to such error‐driven attentional processes. In three
experiments, participants were trained to acquire associations between different
cues and their appeti...
Significance Testing of Difference Potentials
Psychophysiology - Tập 28 Số 2 - Trang 240-244 - 1991
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 autocorrelation parameters is presented.
The Continuing Problem of False Positives in Repeated Measures ANOVA in Psychophysiology: A Multivariate Solution
Psychophysiology - Tập 24 Số 4 - Trang 479-486 - 1987
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. 1981; Mitzel & Games, 1981).

Aging and the Simon task
Psychophysiology - Tập 39 Số 1 - Trang 100-110 - 2002
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
slowing due to...
Influence of caffeine on selective attention in well‐rested and fatigued subjects
Psychophysiology - Tập 31 Số 6 - Trang 525-534 - 1994
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 stimuli presented on the
irrelevan...

THE FIRST NIGHT EFFECT: AN EEG STUDYOF SLEEP
Psychophysiology - Tập 2 Số 3 - Trang 263-266 - 1966
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 and I‐REM and the sleep is
more cha...
