Boredom in the Workplace: A New Look at an Old Problem

Is boredom at work bad for your health? Examining the links between job boredom and autonomic nervous system dysfunction

Job boredom refers to an unpleasant state of passiveness at work that has been found to negatively relate to self-reported health. To date, however, the relation between job boredom and physiological indicators of health has not been examined. The present study investigates whether job boredom relates to dysfunction in autonomic nervous system (ANS) activity as indicated by reduced heart rate variability (HRV) during night sleep. The sample of this study consisted of Finnish public sector workers (n = 125). Job boredom was assessed with an electronic questionnaire and HRV with an ambulatory monitoring period of two nights of sleep. The results supported the hypothesis by showing a negative relation between job boredom and HRV, after controlling for demographic and lifestyle factors. The findings extend previous knowledge on the detrimental consequences of job boredom by showing that it is related to dysfunction in ANS activity. Consequently, it is important to acknowledge boredom at work as a threat to occupational health and well-being and pay more attention to how it can be prevented at workplaces.

Modeling fashion as an emergent collective behavior of bored individuals

Boredom is an aversive mental state that is typically evoked by monotony and drives individuals to seek novel information. Despite this effect on individual behavior, the consequences of boredom for collective behavior remain elusive. Here, we introduce an agent-based model of collective fashion behavior in which simplified agents interact randomly and repeatedly choose alternatives from a circular space of color variants. Agents are endowed with a memory of past experiences and a boredom parameter, promoting avoidance of monotony. Simulating collective color trends with this model captures aspects of real trends observed in fashion magazines. We manipulate the two parameters and observe that the boredom parameter is essential for perpetuating fashion dynamics in our model. Furthermore, highly bored agents lead future population trends, when acting coherently or being highly popular. Taken together, our study illustrates that highly bored individuals can guide collective dynamics of a population to continuously explore different variants of behavior.

Social and economic wellbeing of seafarers across coastal Nigeria amidst Corona virus disease

One of the industries hit hard by the Corona Virus is the shipping industry. This is because there was serious paucity in the movement of people and goods. This also affected not only the social but also the economic well-being of seafarers. Therefore, this study assessed the social and economic well-being of seafarers across coastal Nigeria, amidst COVID. A cross-sectional research design was deployed, and data was generated through questionnaire administration. Analysis was done using Mann Kendal correlation and K-Wallis tests. Findings indicated COVID-19-induced social challenges included fatigue; and sleeping disorders. Mann Kendal correlation analysis indicated a relationship between COVID-19 and social challenges. Among COVID-19-induced economic challenges were unemployment, sacking, and salary slash. The Kendal relationship between COVID-19 and economic challenges was significant, implying, social challenges encountered by seafarers were related to COVID-19. K-Wallis test outcome for the spatial difference in economic challenges encountered by seafarers was significant. Implying a significant difference in the economic challenges posed by COVID-19 on seafarers in the study area. Based on the findings herein, social engagement programs, and poverty alleviation schemes are among the recommendations advanced for seafarers.

How does the work-life balance impact stress on primary healthcare workers during the COVID-19 pandemic?

BACKGROUND

Most studies in advanced care settings reported that the increasing workload increases the work-life imbalance and harms the mental health of health workers. The COVID-19 Pandemic's tracing, testing, treatment, and mass vaccination also have multiplied the primary healthcare workers' workload. Nevertheless, studies on primary care workers are scarce. This study aimed to investigate how the COVID-19-related work-life balance impact stress on primary healthcare workers in the third years of the pandemic.

METHODS

The study was a cross-sectional, web-based survey conducted on primary healthcare workers in Kediri Regency, Indonesia, with the highest Omicron case surge worldwide. It was conducted right after the surge between July and August 2022, the third year of the COVID-19 pandemic hit Indonesia. Under coordination with the local government health officials, primary healthcare workers were invited to participate in an online survey. The respondents were asked to evaluate their sociodemography, work conditions, personal life, and perceived stress (using the Perceived Stress Scale) during the pandemic. Their work-life balance was evaluated using the Work/Non-work Interference and Enhancement Scale. We used several hierarchical linear regression models to determine which variables contribute to work stress among primary healthcare workers.

RESULTS

Sociodemographic characteristics, including gender, age, marital status, years of professional experience, and educational level, were not significantly associated with stress levels among our respondents. Separately, work conditions and personal life variables did not associate with stress levels. However, primary healthcare workers' work and personal lives interfere with each other during the pandemic and are associated with their higher stress.

CONCLUSION

During the pandemic, the work life of primary health workers interferes with their personal life more than the interference of personal life on their work life. At the same time, the work life's enhancement on the personal life and vice versa were lower than its interference. Those conditions are associated with higher perceived stress of primary health workers.

Using EEG to investigate the influence of boredom on prospective memory in top-down and bottom-up processing mechanisms for intelligent interaction

We aimed to investigate the alpha (α) activity in operators experiencing boredom while performing prolonged monitoring and prospective memory tasks using different processing mechanisms. Fifty-four participants underwent electroencephalography (EEG) and were found to have poorer prospective memory performance under top-down conditions. Further, α power and synchronisation were higher during bottom-up than in top-down processes, revealing an inhibition effect of the former. Significant differences in brain regions and hemispheres were identified to distinguish different cognitive processes in both information-processing mechanisms. Thus, people are likely to cope with boredom differently in terms of top-down and bottom-up processes. Specifically, a higher attention level was reported during top-down processing, to mitigate the negative influences of boredom. Overall, this study provides EEG evidence which suggests that prospective memory can be enhanced in top-down processing during prolonged monitoring tasks by increasing the salience of cues.

In search of boredom: beyond a functional account

Boredom has been characterized as a crisis of meaning, a failure of attention, and a call to action. Yet as a self-regulatory signal writ-large, we are still left with the question of what makes any given boredom episode meaningless, disengaging, or a prompt to act. We propose that boredom is an affective signal that we have deviated from an optimal ('Goldilocks') zone of cognitive engagement. Such deviations may be due to a perceived lack of meaning, arise as a consequence of struggles we are experiencing in attending to a task, or be interpreted as a blunt call to find something different to engage with. Thus, the key to understanding boredom lies in its role in keeping us cognitively engaged.

Preliminary Evidence of EEG Connectivity Changes during Self-Objectification of Workers

Economic objectification is a form of dehumanization in which workers are treated as tools for enhancing productivity. It can lead to self-objectification in the workplace, which is when people perceive themselves as instruments for work. This can cause burnout, emotional drain, and a modification of self-perception that involves a loss of human attributes such as emotions and reasoning while focusing on others' perspectives for evaluating the self. Research on workers self-objectification has mainly analyzed the consequences of this process without exploring the brain activity that underlies the individual's experiences of self-objectification. Thus, this project explores the electroencephalographic (EEG) changes that occur in participants during an economic objectifying task that resembled a job in an online store. After the task, a self-objectification questionnaire was applied and its resulting index was used to label the participants as self-objectified or non-self-objectified. The changes over time in EEG event-related synchronization (ERS) and partial directed coherence (PDC) were calculated and compared between the self-objectification groups. The results show that the main differences between the groups in ERS and PDC occurred in the beta and gamma frequencies, but only the PDC results correlated with the self-objectification group. These results provide information for further understanding workers' self-objectification. These EEG changes could indicate that economic self-objectification is associated with changes in vigilance, boredom, and mind-wandering.

Consumed by Boredom: Food Choice Motivation and Weight Changes during the COVID-19 Pandemic

Boredom is an established cause and correlate of eating behavior. Yet, existing work offers a scattered range of plausible motivations for why this is. We examined among 302 people representative of the adult UK population what motivations they had for selecting food during the COVID-19 pandemic and how this related to boredom. As predicted, bored people choose food less for health reasons and more for convenience. Boredom reduced ethical and 'natural content' motivations for selecting food and was not associated with choosing food to regulate one's mood or to experience unfamiliarity. Boredom was also associated with greater absolute changes in weight over the course of the pandemic. Boredom did not predict weight gains or losses overall. These findings offer insights into the role that boredom plays in eating motivations in particular and health-relevant outcomes in general.

Moving boredom from problem to opportunity: A psychoanalytic perspective on workplace boredom and identity in organizations

The study develops novel perspectives on workplace boredom by investigating how conscious and unconscious aspects of identity work drive responses to it. Based on a psychoanalytic, specifically Lacanian, analysis of 56 narratives in which individuals recount their experience with boredom at work, it explores why boredom is so often portrayed as dysfunctional. The study also examines why it is important to understand and strengthen boredom’s more functional aspects. Specifically, the study advances the idea that boredom offers discursive resources to construct identities in more or less empowering ways with the potential for returning us to the creative possibilities inherent in each lived moment. Implications of this perspective are discussed.

POTATO: Automated pipeline for batch analysis of optical tweezers data

Optical tweezers are a single-molecule technique that allows probing of intra- and intermolecular interactions that govern complex biological processes involving molecular motors, protein-nucleic acid interactions, and protein/RNA folding. Recent developments in instrumentation eased and accelerated optical tweezers data acquisition, but analysis of the data remains challenging. Here, to enable high-throughput data analysis, we developed an automated python-based analysis pipeline called POTATO (practical optical tweezers analysis tool). POTATO automatically processes the high-frequency raw data generated by force-ramp experiments and identifies (un)folding events using predefined parameters. After segmentation of the force-distance trajectories at the identified (un)folding events, sections of the curve can be fitted independently to a worm-like chain and freely jointed chain models, and the work applied on the molecule can be calculated by numerical integration. Furthermore, the tool allows plotting of constant force data and fitting of the Gaussian distance distribution over time. All these features are wrapped in a user-friendly graphical interface, which allows researchers without programming knowledge to perform sophisticated data analysis.

Alpha Oscillations in Parietal and Parietooccipital Explaining How Boredom Matters Prospective Memory

Intelligent interaction alters previous human–machine task allocation patterns. Human workers will suffer from boredom and inattention, posing a significant challenge for the human–machine interaction loop. This study aims to investigate the relationship between boredom and prospective memory, which is a memory form including the detecting, identifying, and executing functions. Thus, the attention and memory mechanisms are critical to complete prospective memory tasks when bored. This study recruited twenty-eight participants and used electroencephalography to measure the alpha power in brain regions. The results indicated that parietal oscillations had a mediation effect on prospective memory, which could be associated with the frequent unstable attention. In addition, this study found that parietooccipital oscillations linked boredom and prospective memory, and the default mode network (DMN) and visual processing during boredom could better explain this finding. The findings of this study suggested that attention management and influences of processing visual information were starting points to cope with boredom because they could help prepare for prospective memory and make optimal decisions accordingly.

Experiences of distortions to the passage of time during the Argentinian Covid-19 pandemic

The Coronavirus-19 global pandemic has forced many governments around the world to enforce "lockdowns" to curtail the spread of the virus. Studies conducted in the UK, France, Italy and Brazil have demonstrated that one consequence of these lockdowns is significant distortion to the speed of the passage of time. The current study sought to establish how the passage of time was experienced during the Argentinian lockdown. An online questionnaire was used to measure passage of time judgments for the day and the week, physical activity, satisfaction with social interaction, the extent to which daily routines had changed due to covid and demographic data. The results show that distortions to the passage of time were widely experienced during the lockdown in Argentina. There was a tendency for participants to report time passing more quickly than normal. A faster passage of time was associated with being a woman, of younger age and more physically active. A slower passage of time was therefore associated with being a man, of older age and less physically active. The results indicate that whilst distortions to the passage of time during the covid-19 crisis appear to be a global phenomenon, cross-cultural differences are apparent in the factors which influence temporal experience.

Experienced entropy drives choice behavior in a boring decision-making task

Boredom has been defined as an aversive mental state that is induced by the disability to engage in satisfying activity, most often experienced in monotonous environments. However, current understanding of the situational factors inducing boredom and driving subsequent behavior remains incomplete. Here, we introduce a two-alternative forced-choice task coupled with sensory stimulation of different degrees of monotony. We find that human subjects develop a bias in decision-making, avoiding the more monotonous alternative that is correlated with self-reported state boredom. This finding was replicated in independent laboratory and online experiments and proved to be specific for the induction of boredom rather than curiosity. Furthermore, using theoretical modeling we show that the entropy in the sequence of individually experienced stimuli, a measure of information gain, serves as a major determinant to predict choice behavior in the task. With this, we underline the relevance of boredom for driving behavioral responses that ensure a lasting stream of information to the brain.

Santé mentale chez les gens de mer : connaissances actuelles et impact de la pandémie COVID 19

Les marins sont exposés à de multiples risques physiques et psychiques. Au cours des dernières années, des études ont mis en exergue des pathologies spécifiques comme la fatigue, l’ennui mais aussi des syndromes anxiodépressifs. Les marins sont également à risque de développer des syndromes de stress post-traumatique (piraterie, accidents de navire ou du travail). La pandémie de COVID-19 impacte fortement les marins avec une estimation de 400 000 d’entre eux embarqués autour du monde avec des prolongations de durées de missions, des difficultés de rapatriement, de relève d’équipage et des soucis financiers liés à la baisse du transport maritime et de fait des embarquements et des impayés de salaires.

Alleviating state boredom through search for meaning and affirmation of workplace heroes

Purpose

Employee boredom is of concern to organizations because of its impact on employees’ quality of work life and productivity. This study aims to test the regulation of workplace boredom through meaning in life by workplace heroes to contribute to theory by examining the relationships between the variables and to practice by uncovering the potential of workplace heroes in alleviating state boredom.

Design/methodology/approach

Using online surveys and structured interviews for a mixed-method study, data were collected for state boredom, meaning in life and hero affirmation at work for a quantitative study, and data from the open-ended questions provided further insights regarding hero affirmation at work for a qualitative study.

Findings

Spearman rank-order correlations concluded correlations between state boredom and meaning in life. However, unlike personal heroes that influence meaning in life, workplace heroes were found not to. The qualitative analysis revealed three prime differences between workplace and personal heroes: proximity, symbolic representation of ideologies and qualities admired in the heroes. These reasons entailed that state boredom was not regulated by workplace heroes.

Originality/value

The model of Coughlan et al. (2019) explored trait boredom regulation through meaning in life by personal heroes. This study tested for the regulation of state boredom through meaning in life by workplace heroes; thus, contributing to theory through a nuanced model with enhanced usefulness in practice. The study also further dissects the concept of heroes by uncovering differences between workplace and personal heroes that perpetrated the differences in the findings.

Emotional Intelligence and Professional Boredom among Nursing Personnel in Greece

Occupational (professional) boredom results in low performance at work. It has been positively associated with high levels of anxiety and depression as well as premature death. However, occupational boredom has not been extensively studied among working nurses. This study aimed to investigate the relationship between emotional intelligence and occupational boredom in nurses working in both public (52.9%) and private (47.1%) health units in Greece. A cross-sectional study was conducted among a convenience sample of 189 nurses (84.7% females) with an average age of 40 years. Emotional intelligence was evaluated with the use of The Trait Emotional Intelligence Questionnaire-Short Form and Professional boredom was assessed with the use of the Boredom Proneness Scale. The majority of Nurses showed relatively high values of total Emotional Intelligence (EI), and marginally low values of overall Professional Boredom. A statistically significant negative correlation was found between the overall Professional Boredom of Nurses and the Well-being, Self-control, Emotionality and Sociability subscales of EI, as well as total EI (p < 0.001). Multiple linear regression analyses showed that the three dimensions of EI (Well-being, Self-Control and Emotionality) explained 39.0% of the variability of the total Professional Boredom of the working Nurses.

Comparing interventions to reduce boredom in a low mental workload environment

Boredom is a common workplace problem. Previous research has suggested that repetitive and monotonous work tasks may lead to boredom. However, these tasks have been reduced due to increased workplace automation. Thus, the current cause of boredom may be due to low mental workload. This research developed a general boredom model and compared the effects of feedback type (performance and ranking) and intervention method (game and quiz) on boredom and task performance. Results revealed that the secondary task interventions can reduce boredom and feedback could shorten the response time. Gender also had a significant influence on response time. Notably, results revealed a 4% probability of task failure during the experiment, indicating other interventions are also required. This research indicates that interventions to reduce boredom caused by low mental workload should be designed differently from tasks that have been designed to combat the boredom caused by repetitive and monotonous work.

EEG Coherence Metrics for Vigilance: Sensitivity to Workload, Time-on-Task, and Individual Differences

The vigilance decrement in performance is a significant operational issue in various applied settings. Psychophysiological methods for diagnostic monitoring of vigilance have focused on power spectral density measures from the electroencephalogram (EEG). This article addresses the diagnosticity of an alternative set of EEG measures, coherence between different electrode sites. Coherence metrics may index the functional connectivity between brain regions that supports sustained attention. Coherence was calculated for seven pre-defined brain networks. Workload and time-on-task factors primarily influenced alpha and theta coherence in anterior, central, and inter-hemispheric networks. Individual differences in coherence in inter-hemispheric, left intro-hemispheric and posterior networks correlated with performance. These findings demonstrate the potential applied utility of coherence metrics, although several methodological limitations and challenges must be overcome.

Distortions to the passage of time during England's second national lockdown: A role for depression

In attempts to control the spread of the Covid-19 virus, many governments have resorted to imposing national lockdowns on their citizens. Previous research has demonstrated the passage of time becomes distorted for many people during these lockdowns. To date, research has only examined how time was experienced early in initial lockdowns. The current study examined whether distortions to the passage of time were also present later into the global pandemic. An online questionnaire was used to collect passage of time judgments for the day, week and 8 month period since the first UK lockdown. In addition, measures of affect, social satisfaction, task-load, compliance and health status were also recorded. The results show that over 80% of people reported experiencing distortion to the passage of time during the second English lockdown in comparison with normal. Depression, satisfaction with social interaction and shielding status were found to be significant predictors of temporal distortion. A slower passage of time was associated with greater depression, shielding and greater dissatisfaction with social interactions. Feeling like it was longer than 8 months since the UK's first lockdown was associated with greater depression, increased dissatisfaction with social interaction and greater change of life as a result of lockdown. The results suggest that distortions to the passage of time are an enduring feature of lockdown life and that different factors predict temporal experience during different points in lockdown.

Portrait of Boredom Among Athletes and Its Implications in Sports Management: A Multi-Method Approach

There is a common misconception that elite athletes enjoy their sports activities so much that they cannot feel bored. However, this research reveals that boredom is a prevalent emotion among professional, amateur, and college athletes that impacts their performance, brand preferences, and overconsumption behaviors. This investigation relies on a multi-method approach. Qualitative data were collected through interviewing athletes (n = 123), and the critical incident technique was used to record factual boredom incidents. Quantitative data were collected through a survey and analyzed using hierarchical regression models. The purpose of the survey was to evaluate athletes’ proneness to boredom and then present a typical sports consumption scenario in which athletes’ brand preferences and overconsumption behaviors were captured. Overall findings from this research indicate that episodes of boredom are common among athletes when they engage in repetitive tasks (34.8%); negative mood is anticipated (16.9%); teammates show a lack of interest and seriousness (15.7%); they must endure periods of waiting (13.5%); there is a lack of competitiveness and goal-setting (10.1%); there is a lack of participation in activities (4.5%); there is a lack of empathy with teammates and coaches (3.3%); and there are infrastructure issues (1.1%). Furthermore, this study presents evidence that boredom negatively impacts athletes’ performance (β = −0.41). Then, in a specific sports consumption scenario that uses sports drinks, this study finds that a more boredom-prone athlete has a higher chance of purchasing different brands of the same product (β = 0.37) and engaging in overconsumption behaviors (β = 0.44). The relationships among boredom, performance, variety seeking, and impulse buying are congruent with previous research on boredom. This research discusses several sports management implications and presents recommendations from coaches on how to cope with athletes’ boredom.

Autopilots in the Operating Room

Automated medical technology is becoming an integral part of routine anesthetic practice. Automated technologies can improve patient safety, but may create new workflows with potentially surprising adverse consequences and cognitive errors that must be addressed before these technologies are adopted into clinical practice. Industries such as aviation and nuclear power have developed techniques to mitigate the unintended consequences of automation, including automation bias, skill loss, and system failures. In order to maximize the benefits of automated technology, clinicians should receive training in human–system interaction including topics such as vigilance, management of system failures, and maintaining manual skills. Medical device manufacturers now evaluate usability of equipment using the principles of human performance and should be encouraged to develop comprehensive training materials that describe possible system failures. Additional research in human–system interaction can improve the ways in which automated medical devices communicate with clinicians. These steps will ensure that medical practitioners can effectively use these new devices while being ready to assume manual control when necessary and prepare us for a future that includes automated health care.

Indexing Mental Workload During Simulated Air Traffic Control Tasks by Means of Dual Frequency Head Maps

In our digitized society, advanced information and communication technology and highly interactive work environments impose high demands on cognitive capacity. Optimal workload conditions are important for assuring employee's health and safety of other persons. This is particularly relevant in safety-critical occupations, such as air traffic control. For measuring mental workload using the EEG, we have developed the method of Dual Frequency Head Maps (DFHM). The method was tested and validated already under laboratory conditions. However, validation of the method regarding reliability and reproducibility of results under realistic settings and real world scenarios was still required. In our study, we examined 21 air traffic controllers during arrival management tasks. Mental workload variations were achieved by simulation scenarios with different number of aircraft and the occurrence of a priority-flight request as an exceptional event. The workload was assessed using the EEG-based DFHM-workload index and instantaneous self-assessment questionnaire. The DFHM-workload index gave stable results with highly significant correlations between scenarios with similar traffic-load conditions (r between 0.671 and 0.809, p ≤ 0.001). For subjects reporting that they experienced workload variation between the different scenarios, the DFHM-workload index yielded significant differences between traffic-load levels and priority-flight request conditions. For subjects who did not report to experience workload variations between the scenarios, the DFHM-workload index did not yield any significant differences for any of the factors. We currently conclude that the DFHM-workload index reveals potential for applications outside the laboratory and yields stable results without retraining of the classifiers neither regarding new subjects nor new tasks.

Comment on Oldenburg, M., Jensen, H.J. Stress and Strain among Seafarers Related to the Occupational Groups. Int. J. Environ. Res. Public Health 2019, doi:10.3390/ijerph16071153

Out of the Loop, in Your Bubble: Mind Wandering Is Independent From Automation Reliability, but Influences Task Engagement

This study examined the influence of automation reliability on task-unrelated mind wandering (MW) frequency and the impact of MW on task engagement. Automated environment features make it particularly prone to increase MW frequency. Through mechanisms like complacency or agency, automating a task could increase MW frequency for the operator. For safety-critical industries, the lower perception and degraded stimuli processing associated with MW, summarized by the term "decoupling hypothesis," are particularly concerning. Sixteen participants supervised an autopilot avoiding obstacles with two levels of reliability. Each condition lasted 45 min. We recorded thoughts as either pertaining to being focused, task-related MW or task-unrelated MW. We also recorded perceived mental demand, trust regarding the autopilot and oculometric measures. Based on questionnaire results, our protocol succeeded in inducing more mental demand and lower trust when the automation was unreliable. Attentional states were not correlated, nor did it influence trust in the system reliability. On the contrary, mental demand ratings and pupil diameter were lower during both task-related and task-unrelated MW, compared to those during the focus attentional state. This shows that perceptual decoupling also affects the engagement of operators in automated environments, which may dramatically lower their ability to supervise automation efficiently. This research informs human-automation designers to consider operator engagement when creating automated systems.

Distress and worry as mediators in the relationship between psychosocial risks and upper body musculoskeletal complaints in highly automated manufacturing

As a result of changes in manufacturing including an upward trend in automation and the advent of the fourth industrial revolution, the requirement for supervisory monitoring and consequently, cognitive demand has increased in automated manufacturing. The incidence of musculoskeletal disorders has also increased in the manufacturing sector. A model was developed based on survey data to test if distress and worry mediate the relationship between psychosocial factors (job control, cognitive demand, social isolation and skill discretion), stress states and symptoms of upper body musculoskeletal disorders in highly automated manufacturing companies (n = 235). These constructs facilitated the development of a statistically significant model (RMSEA 0.057, TLI 0.924, CFI 0.935). Cognitive demand was shown to be related to higher distress in employees, and distress to a higher incidence of self-reported shoulder and lower back symptoms. The mediation model incorporating stress states (distress, worry) as mediators is a novel approach in linking psychosocial risks to musculoskeletal disorders. Practitioners' Summary With little requirement for physical work in many modern automated manufacturing workplaces, there is often minimal management focus on Work-Related Musculoskeletal Disorders (WRMSDs) as important occupational health problems. Our model provides evidence that psychosocial factors are important risk factors in symptoms of WRMSD and should be managed.

Auditory Task Irrelevance: A Basis for Inattentional Deafness

Objective This study investigates the neural basis of inattentional deafness, which could result from task irrelevance in the auditory modality. Background Humans can fail to respond to auditory alarms under high workload situations. This failure, termed inattentional deafness, is often attributed to high workload in the visual modality, which reduces one's capacity for information processing. Besides this, our capacity for processing auditory information could also be selectively diminished if there is no obvious task relevance in the auditory channel. This could be another contributing factor given the rarity of auditory warnings. Method Forty-eight participants performed a visuomotor tracking task while auditory stimuli were presented: a frequent pure tone, an infrequent pure tone, and infrequent environmental sounds. Participants were required either to respond to the presentation of the infrequent pure tone (auditory task-relevant) or not (auditory task-irrelevant). We recorded and compared the event-related potentials (ERPs) that were generated by environmental sounds, which were always task-irrelevant for both groups. These ERPs served as an index for our participants' awareness of the task-irrelevant auditory scene. Results Manipulation of auditory task relevance influenced the brain's response to task-irrelevant environmental sounds. Specifically, the late novelty-P3 to irrelevant environmental sounds, which underlies working memory updating, was found to be selectively enhanced by auditory task relevance independent of visuomotor workload. Conclusion Task irrelevance in the auditory modality selectively reduces our brain's responses to unexpected and irrelevant sounds regardless of visuomotor workload. Application Presenting relevant auditory information more often could mitigate the risk of inattentional deafness.

Autopilot, Mind Wandering, and the Out of the Loop Performance Problem

To satisfy the increasing demand for safer critical systems, engineers have integrated higher levels of automation, such as glass cockpits in aircraft, power plants, and driverless cars. These guiding principles relegate the operator to a monitoring role, increasing risks for humans to lack system understanding. The out of the loop performance problem arises when operators suffer from complacency and vigilance decrement; consequently, when automation does not behave as expected, understanding the system or taking back manual control may be difficult. Close to the out of the loop problem, mind wandering points to the propensity of the human mind to think about matters unrelated to the task at hand. This article reviews the literature related to both mind wandering and the out of the loop performance problem as it relates to task automation. We highlight studies showing how these phenomena interact with each other while impacting human performance within highly automated systems. We analyze how this proximity is supported by effects observed in automated environment, such as decoupling, sensory attention, and cognitive comprehension decrease. We also show that this link could be useful for detecting out of the loop situations through mind wandering markers. Finally, we examine the limitations of the current knowledge because many questions remain open to characterize interactions between out of the loop, mind wandering, and automation.

Effects of platooning on signal-detection performance, workload, and stress: A driving simulator study

Platooning, whereby automated vehicles travel closely together in a group, is attractive in terms of safety and efficiency. However, concerns exist about the psychological state of the platooning driver, who is exempted from direct control, yet remains responsible for monitoring the outside environment to detect potential threats. By means of a driving simulator experiment, we investigated the effects on recorded and self-reported measures of workload and stress for three task-instruction conditions: (1) No Task, in which participants had to monitor the road, (2) Voluntary Task, in which participants could do whatever they wanted, and (3) Detection Task, in which participants had to detect red cars. Twenty-two participants performed three 40-min runs in a constant-speed platoon, one condition per run in counterbalanced order. Contrary to some classic literature suggesting that humans are poor monitors, in the Detection Task condition participants attained a high mean detection rate (94.7%) and a low mean false alarm rate (0.8%). Results of the Dundee Stress State Questionnaire indicated that automated platooning was less distressing in the Voluntary Task than in the Detection Task and No Task conditions. In terms of heart rate variability, the Voluntary Task condition yielded a lower power in the low-frequency range relative to the high-frequency range (LF/HF ratio) than the Detection Task condition. Moreover, a strong time-on-task effect was found, whereby the mean heart rate dropped from the first to the third run. In conclusion, participants are able to remain attentive for a prolonged platooning drive, and the type of monitoring task has effects on the driver's psychological state.

Does state boredom cause failures of attention? Examining the relations between trait boredom, state boredom, and sustained attention

Boredom is an important personal and social problem, but the phenomena itself remains poorly understood. Recent work has shown that boredom is highly related to attention, and that this relationship may be instrumental in revealing boredom's causes and consequences. In this paper, experimental findings on trait boredom, state boredom, and sustained attention performance are presented. We demonstrate that trait boredom uniquely predicts sustained attention performance, over and above depression and self-report attention problems. We also present exploratory findings consistent with the claim that attention failures may cause boredom and that sustained attention tasks may themselves be boring. Discussion of each of these findings, and potential ramifications for cognitive research as a whole, is included.
