Quality of life in nonorganic and organic sleep disorders: II. Correlation with objective and subjective quality of sleep and awakening.

OBJECTIVE: The purpose of this study of 100 patients suffering from sleep-disorders was to determine correlations between their subjective health-related quality of life (HRQoL) and objective variables in sleep initiation and maintenance, sleep ...

A cross-modal weapon focus effect: The influence of a weapons presence on memory for auditory information.

To examine whether a weapons presence impairs witnesses memory for auditory information (as it impairs memory for visual information), we conducted two experiments in which undergraduates watched one version of a videotape depicting a male target who ...

Circadian fluctuation of time perception in healthy human subjects.

Previous studies suggested that various psychophysiological factors have influences on human time perception. In particular, working memory loads, time of day, body temperature, and mood were known as important modifiers of time perception. The purpose ...

A naturalistic visual scanning approach to assess selective attention in major depressive disorder.

Cognitive biases in information processing play an important role in the etiology and maintenance of emotional disorders. A new methodology to measure attentional biases is presented; this approach encourages subjects to scan and re-scan images with ...

Effects of unilateral pallidotomy on voluntary movement, and simple and choice reaction times in Parkinsons disease.

We studied the effects of unilateral pallidotomy on motor execution and reaction times in patients with moderately advanced Parkinsons disease (PD). Twelve consecutive patients (7 men, 5 women; all right-handed) underwent left-side microelectrode-guided ...

Do video sounds interfere with auditory event-related potentials?

To make the electroencephalogram (EEG) recording procedure more tolerable, listeners have been allowed in some experiments to watch an audible video while their auditory P1, N1, P2, and mismatch negativity (MMN) event-related potentials (ERPs) to ...

Internal versus external attention in social anxiety: an investigation using a novel paradigm.

Several cognitive models propose that social anxiety is associated with increased self-focused attention. Indirect evidence for this hypothesis has been provided by questionnaire studies, and by cognitive psychology paradigms that have demonstrated ...

Attention maintains mental extrapolation of target position: irrelevant distractors eliminate forward displacement after implied motion.

Observers judgments of the final position of a moving target are typically shifted in the direction of implied motion ("representational momentum"). The role of attention is unclear: visual attention may be necessary to maintain or halt target ...

Age-related slowing of digit symbol substitution revisited: what do longitudinal age changes reflect?

A previous investigation reported that cross-sectional age differences in Digit Symbol Substitution (DSS) test performance reflect declines in perceptual processing speed. Support for the tenability of the processing speed hypothesis requires examining ...

Contrasting two accounts of anxiety-linked attentional bias: selective attention to varying levels of stimulus threat intensity.

Previous research has established that clinical anxiety patients and nonclinical populations with high levels of anxiety vulnerability characteristically orient attention toward moderately threatening stimuli. In contrast, populations with low levels of ...
