EEG alpha frequency band biomarkers of depression are widely explored. Due to their trait-like features, they may help distinguish between depressive and burnout symptomatology, which is often referred to as "work-related depression". The present correlational study strived to examine whether individual alpha frequency (IAF), power, and coherence in the alpha band can provide evidence for establishing burnout as a separate diagnostic entity. Resting EEG (eyes closed) was recorded in 117 individuals (42 males). In addition, the participants filled-out questionnaires of burnout and depression. Regression analyses highlighted the differential value of IAF and power in predicting burnout and depression. IAF was significantly related to depressive symptomatology, whereas power was linked mostly to burnout. Moreover, seven out of twelve interactions between EEG indicators and gender were significant. Connectivity patterns were significant for depression displaying gender related differences. The results offer tentative support for establishing burnout as a separate clinical syndrome.

This edited volume contributes to the emerging topic of integrating psychology-driven models into computer personalized applications. The book contains chapters on psychoogycal models, acquisition techniques and usage in applications thus bridging psychology and computer science. From the perspective of the project, the chapters on the unobtrusive measurement of the user state are a contribution

Background: Visual ergonomics has an impact on visual performance in reading. Based on the assumption that reading from an LCD screen held in the hands provides more accurate information about the distance to the object than reading from a screen, which has no contact with our body, this study assessed the influence of the proprioceptive input on the speed of reading and on accommodative and pupillary responses and their micro-oscillations. Methods: Participants (n = 47; all emmetropic, non-amblyopic), were asked to read in their minds two-digit numerals presented on a 10-inch LCD screen at 40 cm distance. In one condition, the participants held the screen in their hands; in the other, the screen was placed on the holder and there was no body contact with the participant. The number of numerals read in 90 seconds was recorded. Accommodative and pupillary responses were measured with Power Refractor 3 at a 50 Hz measurement rate. Results: The number of numerals read was greater for the condition with proprioceptive input than in the condition without contact. The mean pupil size and the average accommodative response were similar in the two conditions. The rate of change in pupil size showed a steeper decline in the condition without the proprioceptive input compared to the condition with this input. The increase in the lag of accommodation with time was similar in both conditions, as well as pupillary and accommodative micro-oscillations. Conclusions: When the screen was held in the hands, reading of numerals was faster and resulted in less pupil size change over the 90-second test interval. This indicates that proprioception might influence some aspects of visual performance.

The aim of our study was to determine whether psychological effects of sensor attachment and the awareness of the subject being measured could influence the posturographic tests performed using the force plate and combined using psychophysiological measurements (EDA, HR, respiration).

The paper presents a procedure for evaluation of system for measuring electrodermal activity of the skin. The procedure consists of static calibration by comparison, dynamic evaluation by means of generated sine signals. Devices conforming to these criteria would be reliable and sufficiently accurate for skin conductance level measurements, with an established metrological traceability and readings linked to the basic units of the international system of units SI.
