Plasma prolactin levels are sensitive to dopamine and serotonin function, and fatigue. Low cortisol, dopamine and/or serotonin may be involved in burnout and detachment.
In this double-blind within-subject study, we treated 9 female burnout subjects and 9 controls with 35 mg cortisol and placebo orally. We measured state affect and plasma prolactin...
Previous results suggest that both cortisol mobilization and the error-related negativity (ERN/Ne) reflect goal engagement, i.e. the mobilization and allocation of attentional and physiological resources. Personality measures of negative affectivity have been associated both to high cortisol levels and large ERN/Ne amplitudes. However, measures of...
Although the focus of the discussion regarding the significance of the error related negatively (ERN/Ne) has been on the cognitive factors reflected in this component, there is now a growing body of research that describes influences of motivation, affective style and other factors of personality on ERN/Ne amplitude. The present study was conducted...
In this study we examined whether the effects of mental fatigue on behaviour are due to reduced action monitoring as indexed by the error related negativity (Ne/ERN), N2 and contingent negative variation (CNV) event-related potential (ERP) components. Therefore, we had subjects perform a task, which required a high degree of action monitoring, cont...
The effects of mental fatigue on attention were assessed. Subjects performed a visual attention task for 3 h without rest. Subjective levels of fatigue, performance measures and EEG were recorded. Subjective fatigue ratings, as well as theta and lower-alpha EEG band power increased, suggesting that the 3 h of task performance resulted in an increas...
The acute effects of cortisol (35mg) administration in 11 healthy male volunteers on resting frontal EEG asymmetry measured in the alpha band were investigated, using a within-subjects double-blind design. Results were indicative of a relative increase of right frontal activity with cortisol. This pattern of activity is similar to the deviant patte...
In a recent study we investigated the acute effects of cortisol administration in healthy male volunteers on free recall of pleasant, unpleasant, and neutral nouns using a between-subjects double-blind placebo-controlled design. The volunteers were administered 10 mg of hydrocortisone or placebo between 9:00 and 10:30. Two hours after administratio...
When drivers perform additional tasks while driving, research shows conflicting results: primary driving performance may deteriorate but adaptive changes such as reducing driving speed have also been noted. We hypothesized that the nature of the secondary task may be important: drivers may give more priority to tasks that serve goals of the driving...

To stress or relax: neurochemical aspects of activity and rest
M. Tops, M.M. Lorist, A.A. Wijers & T.F. Meijman, Gedrag & Organisatie, volume 17, February 2004, nr. 1, pp. 32-42.
In this paper we formulate ideas about acute and chronic fatigue (especially burnout) in terms of brain neur...
To present the available empirical evidence for the assumed position of the concept of work related fatigue as: (1) short term effect of the working day; and (2) an intermediate variable between work demands and the development of subjective health complaints and sickness absence.
Results from six single occupation studies, conducted between 1996 a...
We tested whether behavioural manifestations of mental fatigue may be linked to compromised executive control, which refers to the ability to regulate perceptual and motor processes for goal-directed behaviour. In complex tasks, compromised executive control may become manifest as decreased flexibility and sub-optimal planning. In the study we use...
The present study investigated the acute effects of cortisol administration in normal healthy male volunteers on immediate free recall and recognition of pleasant, unpleasant, and neutral nouns using a between-subjects double-blind design. Two hours after cortisol (10 mg) or placebo administration, impaired recall and recognition of neutral and ple...
During fatiguing submaximal contractions a constant force production can be obtained at the cost of an increasing central command intensity. Little is known about the interaction between the underlying central mechanisms driving motor behaviour and cognitive functions. To address this issue, subjects performed four tasks: an auditory choice reactio...
This cross-sectional questionnaire study presents a multi-level analysis on 2565 workers in 188 departments in 36 organizations in the Netherlands. A three-level model is used in which individual workers are nested within departments, which in turn are nested within organizations. Research questions concern (1) the amount and distribution of varian...
An experiment was carried out in a driving simulator in order to study time-on-task effects in driving with special attention to distance keeping and hazard avoidance performance. As expected, increases of fatigue in the course of sustained performance were associated with a deterioration of perceptual-motor performance and an increase of safety ma...
The effects of variables derived from a work stress theory (the effort-reward imbalance theory) on the power in the high frequency (HF_HRV) band of heart rate (0.14-0.40 Hz) throughout a work day, were determined using multilevel analysis. Explanatory variables were analysed at two levels: at the lowest level (within-day level), the effects of posi...
The purpose of this cross-sectional study with repeated measurements was to find out to what extent neuroendocrine reactivity during work and neuroendocrine recovery from work, and work characteristics, are related to subjective need for recovery and perceived health status.
Neuroendocrine reactivity and recovery were studied in 59 subjects by meas...
The effects of mental fatigue on planning and preparation for future actions were examined, using a task switching paradigm. Fatigue was induced by "time on task," with subjects performing a switch task continuously for 2 hr. Subjects had to alternate between tasks on every second trial, so that a new task set was required on every second trial. Ma...
The purpose of this study was to examine the extent to which the type or nature (physical, mental or mixed mental and physical) of work and work characteristics is related to the course of neuroendocrine reactivity and recovery from work.
Neuroendocrine reactivity and recovery were studied by measuring the urinary excretion of adrenaline, noradrena...
Car drivers appear to reduce their driving speed in high task demand situations. Summala's [Safety Sci. 22 (1996) 103–117]; [in: J.A. Rothengatter, & E. Carbonell Vaya (Eds.), Traffic and Transport Psychology: Theory and Application, Pergamon, Oxford, 1997, pp. 41–52] model of behavioural adaptation (MBA) also assumes that drivers increase speed in...
To review occupational health, laboratory, and sports literature on neuroendocrine reactivity and recovery from mental, combined mental and physical, or physical tasks.
A systematic literature search was performed in eight databases. Studies with catecholamines or cortisol as effect variables measured in blood, urine, or saliva were included.
After...
This study investigates the hypothesis that long lasting mental work demands are reflected in after-effects on attention demanding post-test probe tasks. Sixteen subjects were engaged in 2 simulated workdays consisting of mentally demanding tasks. On the difficult day the afternoon consisted of highly demanding information processing tasks; on the...
The effects of explanatory variables derived from a work stress model (the effort-reward imbalance model) on salivary cortisol were assessed. A multilevel analysis was used to distinguish the effects of single occasion and multiple occasion measurements of work stress and effect on cortisol. The single (or cross-sectional) factors include Effort-Re...
Presents an obituary for Bert Mulder, who lost his struggle with illness on 12 December 1999. His fascination with the neural basis of cognition and action led Mulder to found one of the first laboratories in The Netherlands for research on event-related brain potentials. Bert Mulder was a convinced and true cognitive neuroscientist and one of the...
Driving is a task that requires the timely detection of critical events and relevant changes in traffic circumstances. Adaptation of speed and safety margins allows drivers to control the time available to react to potential hazards. One of the basic safety margins in driving is the time headway preserved with respect to cars ahead. To avoid rear-e...
The present study was designed to elucidate the effect of depressive symptomatology on the cortisol response to strenuous exercise. Thirteen healthy, post-menopausal women participated in this study. The results show that acute bicycle exercise activates the hypothalamic-pituitary-adrenal (HPA) axis resulting in rapid increases in plasma cortisol....

Two experiments were carried out in a driving simulator in order to study driving behaviour in reduced visibility conditions. Both studies show that drivers maintain larger time headways when preview is limited. The results suggest that the adaptation of time headway was related to difficulty of anticipation rather than perceptual degradation due t...

Mental fatigue was studied by analysing performance and mental effort in a memory search task in relation to the temporal structuring of preceding work periods.Performance was measured by reaction time and error rate. Mental effort was measured via spectral analysis of the 0.10 Hz component in the heart rhythm signal.It was shown that subjects prot...
The main objective is to describe the potential health and work problems of the aging employees in the Dutch working population. In this way, we can identify groups at extra risk of specific health problems.
In The Netherlands, occupational health services gather questionnaire data about work and health as part of periodical occupational health sur...
In the demand-control model (see T. Theorell & R. A. Karasek, 1996), it is hypothesized that workers in active jobs (high demands-high decision latitude) can exert effective coping strategies when confronted with environmental stessors. Thus, when exposed to similar levels of a chemical agent, lower concentrations of this agent in blood could be ex...
Used the passive-active dimension of the job demand–control model (T. Theorell and R. A. Karasek, see record 83:28881) to examine the impact of behavioral factors on the exposure to and actual uptake of airborne lead in 2 lead exposed populations of male workers (18 from an electric accumulator factors and 18 from a lead smeltery) and to ascertain...
To investigate to what extent vocational rehabilitation and working on a trial basis have an impact on employment after rehabilitation.
Follow-up survey, conducted in 1991, among all patients, aged 14 to 64, who were treated between 1984 and 1987.

Absenteeism, turnover and disability, and relationships between them have been studied among city bus drivers in the Netherlands. The theoretical framework for the study was a cumulative process model of work and health. Absenteeism among these drivers was two to three times as high as the national average, while the risk of disablement was more th...
The ultimate goal of occupational health practice and research with respect to the use of chemical substances at work is the prevention of adverse effects (Samuels 1986). Contrary to well-controlled experimental dose-effect studies, one is confronted in practice with a multitude of effect-modifying variables, influencing not only the dose but also...

... In a study with a sample of bus-drivers, a negative correlation was found between time demands and safety. Drivers either had a preference for being on schedule, and thus tended to pay less attention to the requirement to drive safely, or they had a preference for driving safely and, therefore, paid less attention to the requirement to stay on schedule (Meijman and Kompier, 1998). ...
... Dat strookt met het gegeven dat cortisol in de hersenen vooral dopaminerge activiteit stimuleert (Dalman et al., 2006). Dopamine is een modulator van energetisch gedrag en van een waargenomen kosten-baten (effortreward) balans (Salamone et al., 1999;Tops et al., 2004;Walton et al., 2003). Soms roept langduriger cortisoltoediening bij sommige mensen depressieve gevoelens op (maar vaker toegenomen gevoelens van energie). ...

... Contemporary research into physiological and physical health correlates of stress began in the 1920s and 1930s with the work of Cannon (1929Cannon ( , 1931 and Selye (1936). Since then much has been published in this area (e.g., Kawakami & Haratani, 1999;Landsbergis et al., 1995;Meijman et al., 1995). A large body of data has been accumulated concerning physiological responses in people exposed to stressors in laboratories. ...

... Older workers showed less fatigue than the young during the first two nights, while the opposite age-related pattern was subsequently observed. It may be that our results reflect an average situation, thus masking possible age-related temporal differences in the way workers cope with atypical work hours (De Zwart and Meijman, 1996). ...
... Hieruit kunnen we concluderen dat het bij ziekteverzuim gaat over de belastbaarheid (bijvoorbeeld vaardigheden en capaciteiten) en houding (motivatie om zich in te zetten) in relatie tot wat van de werknemer wordt gevraagd (werkbelasting). Ziekteverzuim kan dus worden gezien in termen van een gebrek aan evenwicht tussen de werknemer en zijn of haar omgeving (Van Dijk et al., 1990). ...

... A number of studies have reported that psychological states, such as motivation and pressure to participate in the rehabilitation program, affect a patient's engagement in the rehabilitation program [15,19,21]. Previous studies linked the patient's engagement in the rehabilitation program with the rate of recovery from motor impairments [22]. ...
... Megaw (1995) reviewed 95 articles on visual fatigue and concluded we do not know much about visual fatigue. Meijman (1995) pointed out that people can maintain mental performance by exerting more effort; as an index of mental effort, he used the .1 Hz component in the heart beat. ...

... Generally the driver models in SUMO aim towards an accident free traffic flow. Driver models, which adapt their behaviour to other participants are described in [9]. If the modelled leader vehicle determines the behaviour of the following vehicles, the driver model is named a car-following model, which is the basis of SUMOs vehicle behaviour. ...
... They were measured with reliable scales originating from the Dutch Quality of Work Questionnaire (Vragenlijst Beleving en Beoordeling van de Arbeid [VBBA]) measuring quantitative job demands, emotional job demands, and physical job demands. 63 The CATPCA resulted in a five-point scale for the type of work schedule. The quantifications of the type of work schedule and weekly working hours, age, education, and sex have paths to sickness absence duration and episodes, and to health and motivation. ...
