Even though disgust and fear are both negative emotions, they are characterized by different physiology and action tendencies. The aim of this study was to examine whether fear- and disgust-evoking images would produce different attention bias effects, specifically those related to attention (dis)engagement. Participants were asked to identify a target(More)
To examine the time course and automaticity of our attention bias towards attractive opposite sex faces, event-related potentials (ERPs) were recorded from 20 males and 20 females while they carried out a covert orienting task. Faces that were high, low or average in attractiveness, were presented in focus of attention, but were unrelated to task goals.(More)
We investigated whether directed forgetting as elicited by the item-cueing method results solely from differential rehearsal of to-be-remembered vs. to-be-forgotten words or, additionally, from inhibitory processes that actively impair retrieval of to-be-forgotten words. During study, participants (N=24) were instructed to remember half of a series of(More)
The aim of this study was to investigate whether information processing persists during general anesthesia, and if so, to determine the relationship between the degree of cognitive processing measured during anesthesia and the presence or absence of intraoperative memories measured after anesthesia. Subjects were 12 patients, undergoing cardiac surgery with(More)
This study sought to establish a method of quantifying subjective perceptions of sleep against perceptions of life-quality and mood, using amended versions of the Pittsburgh sleep diary (PghSD) and quality of life of insomniacs (QOLI) questionnaire. Diaries and questionnaires were self-completed in participants' homes. Outpatients with a DSM-IV diagnosis of(More)
This study sought to investigate whether first-degree relatives of depressed patients report, and react to, sleep perceptions in the same way as the depressed group. Our previous research suggested that depressed individuals may experience greater sleep 'distress' than healthy individuals; we wished to explore whether this was also apparent in their nearest(More)
The present study examined the electrophysiological correlates of intentional forgetting using the item-method directed forgetting paradigm. Participants (N=23) studied a series of words each followed by either a "remember" cue (TBR) or a "forget" cue (TBF) and then undertook an old/new recognition memory test for which they were requested to endorse(More)
To investigate the incidence and manner of auditory information processing during a state of presumed unconsciousness event-related brain potentials (ERPs) were studied in 41 patients undergoing cardiac surgery with propofol/alfentanil anesthesia. The ERPs were recorded during auditory oddball tasks administered before and within several periods of the(More)
To identify alterations in elementary cognitive operations according to dimensions of depression, two stages of information processing, namely the response choice and the motor preparation stages, were explored using an event-related potential paradigm in two subgroups of depressed patients (retarded and blunted affect versus anxious-agitated and impulsive)(More)
