Five studies with nearly 500 subjects recruited from the university, the work place, and from rehabilitation clinics served to investigate the perception of emotional events in everyday life. Physiological parameters (heart rate, physical activity, additional heart rate) and psychological parameters (excitement, enjoyment) were assessed simultaneously(More)
Additional heart rate as an indicator of emotional arousal was monitored throughout the day with a special ambulatory device. Fifty female students received acoustic feedback every 10-20 min. The feedback was based either on events (additional heart rate present) or was random without additional heart rate. Following the feedback the subjects were asked to(More)
Heart rate is a well-established indicator of emotional arousal and can serve to detect emotional events. One difficulty, however, is in separating emotional heart rate increases from those increases due to physical activity. On-line analysis of both heart rate and physical activity (recorded with motion detectors) with a portable minicomputer may be able(More)
This study of 50 female students (mean age 23) investigated the level of acute and chronic subjective stress, objective strain of everyday university life, and behavior (time budget during a normal day). Physiological parameters, behavioral activities, and psychological parameters were assessed simultaneously both while at the university and at home using a(More)
This study, using 12 train drivers on a high speed track and 11 drivers on a mountain track, tried to differentiate between the physical, emotional, mental, and subjective workload components imposed on the drivers during work. With the simultaneous recording and on-line analysis of heart rate and physical activity, the emotional component in terms of the(More)
Schizophrenic patients and their first-degree relatives exhibit deficits in the anti-saccade task. In the present study, anti-saccade task performance was examined in subjects with 'high' and 'low' expressions of the schizotypal personality trait. For that purpose, the SPQ-G, the German adaptation of the Schizotypal Personality Questionnaire (SPQ; Raine,(More)
Several hypotheses describe the phenomenon asymptomatic myocardial infarction (MI) blockade of afferent cardiac nerves, pain inhibition by endogenous opioids, and insufficient severity of myocardial ischaemia. Psychological factors, however, are rarely considered. The present study involved 35 asymptomatic (AMI) and 35 symptomatic patients (SMI) selected(More)
This study of 29 blue and 57 white collar workers (mean age 50 and 51 yr) investigated behavior and the level of subjective stress and objective strain during work and leisure time. Physiological and psychological parameters as well as behavioral activities were assessed simultaneously using a special ambulatory monitoring device capable of storing 23 h(More)
ECG and physical activity (recorded with motion detectors) were continuously monitored during 23 hours in 31 male cardiac patients (81% with myocardial infarction). According to the occurrence of ventricular arrhythmias (VA) or ischemic episodes (IE), each patient was grouped in one of three diagnostic categories: neither VA nor IE, VA with or without IE,(More)
Relationships between the time series of five physiological sleep parameters were examined and related to sleep quality. Twenty-eight male coronary patients participated in the investigation. Recordings were carried out with a mobile device consisting of two Medilog 4-24 recorders and one DMI-recorder assessing five biosignals: EEG, EOG, EMG, ECG and body(More)
