Abstract. The aim of the study was to explore the effects of situational stress and anxiety in a group of healthy elderly, both in terms of psychophysiological correlates and cognitive performance. Eighteen participants ( Mage = 70 ± 6.3; range 60–85) were assessed for anxiety and were instructed to perform a computerized math task, under both a stressful and a control condition, while near-infrared spectroscopy (NIRS) signal and electrocardiography (ECG) were recorded. NIRS results evidenced an increased activation of right PFC during the entire procedure, even if effect sizes between left and right channels were larger during the experimental condition. The amount of right activation during the stressful condition was positively correlated with anxiety. Response times (RTs) were slower in more anxious than in less anxious individuals, both during the control and stressful conditions. Accuracy was lower in more anxious than in less anxious individuals, only during the stressful condition. Moreover, heart rate (HR) was not modulated by situational stress, nor by anxiety. Overall, the present study suggests that in healthy elderly, anxiety level has a significant impact on cerebral responses, and both on the amount of cognitive resources and the quality of performance in stressful situations.

People regularly interact with automation to make decisions. Research shows that reliance on recommendations can depend on user trust in the decision support system (DSS), the source of information (i.e. human or automation), and situational stress. This study explored how information source and stress affect trust and reliance on a DSS used in a baggage scanning task. A preliminary sample of sixty-one participants were given descriptions for a DSS and reported trust before and after interaction. The DSS gave explicit recommendations when activated and participants could choose to rely or reject the choice. Results revealed a bias towards self-reliance and a negative influence of stress on trust, particularly for participants receiving help from automation. Controlling for perceived reliability may have eliminated trust biases prior to interaction, while stress may have influenced trust during the task. Future research should address potential differences in task motivation and include physiological measures of stress.

OBJECTIVE: To develop a conceptual path model to explain the effects of a set of personal and work-related independent variables and the dependent variables of situational stress, job stress and job motivation on job satisfaction among critical care nurses. DESIGN: A prospective descriptive study using a conceptual path model. SETTING: Nine hospitals licensed for at least 250 beds in the northeastern, northwestern, northcentral, and southern regions of Florida. SAMPLE: Three hundred female critical care nurses employed in the nine hospitals who had worked full-time for at least 3 months. MEASUREMENTS: Subjects were administered a demographic and work survey questionnaire, Daily Hassles Instrument, Psychological Hardiness Test and the Job Diagnostic Inventory. MAIN OUTCOME MEASURES: A conceptual path model was constructed to illustrate the effects of a set of personal and work-related independent variables and the dependent variables of situational stress, job stress and job motivation on job satisfaction. MAIN RESULTS: Path analysis of a job satisfaction model resulted in a causal progression of situational stress leading to either job stress or job motivation, both affecting job satisfaction. The results showed that job stress, job motivation, job expectations, meaningful work, knowledge of work results, commitment to career, health difficulties, task identity, supervision, dealing with others at work, opportunity for advancement, pay and job security had a significant effect on job satisfaction. CONCLUSION: Thirteen variables had a significant effect on job satisfaction and explained 63% of the variance. The four most significant effects on job satisfaction were opportunities for advancement, meaningfulness of work, pay and supervision. Commitment to the career, task identity and job security had a modest effect on job satisfaction.

Assessment of risk for violent behavior is of interest to clinicians and laymen alike. This article includes a discussion of issues related to assessment of risk of violent behavior. A review of the literature is provided. Using this information, the author suggests several factors that might increase the probability of violent behavior in historically nonviolent individuals, including antisocial behavior, social isolation, poverty, absence of support systems, severe situational stress, and substance abuse. A checklist for assessing risk of violent behavior is suggested.
