BACKGROUND Hypochondriacal attitudes were associated with cognitions not related to illness: Social fears, low self-esteem, and reduced warm glow effect, i.e. less positive appraisal of familiar stimuli. Only a single study had investigated the correlation of hypochondriacal attitudes with the warm glow effect so far and the present study aimed to(More)
The relation between hypochondriacal attitudes, thermal pain threshold, and attentional bias toward pain was examined in a non-clinical population (N = 28). Attentional bias was operationalized with a concentration-performance test, which subjects performed while connected to a pain stimulator. Subjects were informed that they would receive a painful(More)
BACKGROUND Pitch identification had yielded unique response patterns compared to other auditory skills. Selecting one out of numerous pitches distinguished this task from detecting a pitch ascent. Encoding of numerous stimuli had activated the intraparietal sulcus in the visual domain. Therefore, we hypothesized that numerosity encoding during pitch(More)
BACKGROUND Cognitive deficits are a substantial burden in clinical depression. The present study considered dysfunction in the right-hemispheric attention network in depression, examining alertness and visuospatial attention. METHODS Three computerized visuospatial attention tests and an alertness test were administered to 16 depressive patients and 16(More)
Aggressive behavior is associated with dysfunctions in an affective regulation network encompassing amygdala and prefrontal areas such as orbitofrontal (OFC), anterior cingulate (ACC), and dorsolateral prefrontal cortex (DLPFC). In particular, prefrontal regions have been postulated to control amygdala activity by inhibitory projections, and this process(More)
The indoleamines serotonin and melatonin (MT) affected visual processing such as choice reaction. This study determined whether the indoleamines influence the processing of auditory stimuli. Serotonergic activity was increased using citalopram (CIT). We compared effects of single doses of 40 mg CIT, 1 mg MT, and placebo (randomized double-blind, cross-over(More)
BACKGROUND Due to the unique neural projections of the olfactory system, odours have the ability to directly influence affective processes. Furthermore, it has been shown that emotional states can influence various non-emotional cognitive tasks, such as memory and planning. However, the link between emotional and cognitive processes is still not fully(More)
This study aimed to develop tests for differentiating auditory perception skills, e.g., to test drug effects. In Exp. 1 (N = 60), discrimination of succeeding frequencies, frequency identification assessed by a choice reaction task, and the perception of pitch contour assessed by frequency deviants in binaural melodies showed zero partial correlations. In(More)
Previous findings suggested that hypochondriacal attitudes could originate from a pessimistic trait independent of illness-related thoughts. We hypothesised that hypochondriacal attitudes correlated with a general cognitive tendency towards negative interpretations and reduced familiarisation. Healthy non-patients were invited to participate. The sum score(More)
