How does negative mood affect risk taking? A brief questionnaire was used to measure state anxiety, depression, and fatigue, a daily diary allowed trait (average level) be separated. Studies 1 2 natural moods Study 3 induction procedure. Risk assessed using hypothetical everyday choice scenarios. showed that riskiness affected by but not anxiety depression. increased over two - week period predicted fatigue changes, after controlling for at time 1. Fatigue effects were stronger more...
This study was carried out to test the compensatory control model, which predicts performance maintenance under stress at expense of effort and increased selectivity. It examined effects sleep deprivation on in an automated process task based a simplified life support system with two types operator panel interface: machine centered (M-C), access scheduled by computer, human-centered (H-C), ad-lib. The environment also permitted analysis changes strategy subsidiary activities (alarm reaction...
Four groups of 6 extraverts and 4 introverts, selected by the Maudsley Personality Inventory, performed a 32 min visual cancellation task under one two conditions signal frequency, high low, in either noise (95 db) or quiet (70 db). In quiet, at both levels showed steady decline number signals detected correctly but introverts did not. Neither group decrement conditions. Noise, compared with significantly increased correct detections made low frequency similar increase was not significant....
The demands of dynamic monitoring and fault diagnosis for flight engineer trainees were examined in relation to changes heart rate (HR) two spectral analysis measures (midfrequency: 0.07-0.14 Hz; high frequency: 0.15-0.40 Hz) variability (HRV). Eleven trainee engineers studied, as part their training assessment, over three 3-h sessions a cockpit simulator. During each session, faults incidents programmed into the system had be detected, diagnosed, corrected. Electrocardiograms taken, session...
As mobile office technology becomes more advanced, drivers have increased opportunity to process information "on the move." Although speech-based interfaces can minimize direct interference with driving, cognitive demands associated such systems may still cause distraction. We studied effects on driving performance of an in-vehicle simulated "E-mail" message system; E-mails were either system controlled or driver controlled. A high-fidelity, fixed-base simulator was used test 19 participants...
Two experiments tested the hypothesis that task-induced mental fatigue is moderated by control over work scheduling. Participants worked for 2 hr on simulated office work, with manipulated a yoking procedure. Matched participants were assigned to conditions of either high (HC) or low (LC). HC decided their own task scheduling, whereas LC had follow these fixed schedules. For Experiment 1, was higher in who harder, so compared effects high- and low-workload groups. As predicted, impact...
This paper proposes a new framework for the online monitoring and adaptive control of automation in complex safety-critical human-machine systems using psychophysiological markers relating to humans under mental stress. The starting point this relates assessment so-called operator functional state measures. An fuzzy model linking heart-rate variability task load index with subjects' optimal performance has been elicited validated offline via series experiments involving process tasks...
High-quality engineering and operations management are key to meeting all the requirements of a successful railway-quality service, reliable safe performance, maximum possible use capacity. However, railway is socio-technical system therefore has human factors at its core, which requires strong integrated ergonomics contribution. Moreover, this contribution must be systems level rather than providing point solutions particular equipment, interface, workplace, or job problems. This paper...
An experiment was carried out to test the hypothesis that environmental treatments thought change arousal in opposite directions (noise and loss of sleep) will also produce opposing changes degree selectivity attention allocation. A dual task method employed, subjects having perform a primary tracking while simultaneously monitoring an array light sources for occasional signals (the subsidiary task). The effect sleep significantly impair performance task, reduce advantage high‐probability...
