According to legislation, take-overs initiated by the driver must always be possible during automated driving. For example, when drivers mistrust the automation to handle a critical and hazardous lane change, they might intervene and take over control while the automation is performing the maneuver. In these situations, drivers may have little time to avoid an accident and can be exposed to high lateral forces. Due to lacking research, it is yet unknown if they recognize the criticality of the situation and how they behave and perform to manage it. In a driving simulator study, participants (N = 60) accomplished eight double lane changes to evade obstacles in their lane. Time-to-collision and traction usage were varied to establish different degrees of objective criticality. To manipulate these parameters as required, participants were triggered to take over control by an acoustic cue. This setting shows what might happen if drivers disable the automation and complete the maneuver themselves. The results of the experiment demonstrate that drivers rated objectively more critical driving situations as more critical and responded to the hazard very fast over all experimental conditions. However, their behavior was more extreme with respect to decelerating and steering than necessary. This impaired driving performance and increased the risk of lane departures and collisions. The results of the experiment can be used to develop an assistance system that supports driver-initiated take-overs.  相似文献

A proportion of 55 % of school administrators experience a high level of job stress mainly caused by relationship conflicts and overwork. According to the demands and resources of employment model, having personal resources would protect against the harmful effect of the difficulties experienced and the more specific a resource, the more it can counter the effect. Thus, political skills (HP) would decrease the effect of demands related to relationship conflicts, while the sense of self-efficacy (PES) decreases the negative impact of the workload on the PES. The objective of this study is to verify the effect of personal resources, HP and MS, on the relationship between job demands and job psychological health. A total of 232 school administrators from Quebec participated in the study. Job demands, as well as personal resources, are linked to anxiety and serenity according to Bakker and Demerouti (2007). Nevertheless, the SEP does not interact with the relationship of demands and psychological health in employment (PES). In addition, only the social astuteness dimension of HP moderates the relationship of demands and anxiety.  相似文献

The Australian population is experiencing a rapid ageing of the population, and as such, an increased need for gerontological practitioners in the helping professions will continue to grow. Terror management theory (TMT), which was used to frame this study, posits that because of the fact that humans are aware of their own mortality, they are compelled to avoid the anxiety associated with it. Personal ageing and interaction with older adults may be reminders of the unavoidable decline and death that faces us all. The purpose of this study is to examine comfort in spending time with older adults amongst students, academic teaching staff, and practitioners in the fields of psychology and social work. We sought to determine if TMT helped predict fear of being with older adults. Ageism, contact with older adults, and known demographic factors associated with attitudes towards older adults were also examined. Hierarchical multiple regression explained nearly 46% of the variance in comfort with older adults and indicated that fear of ageing, positive ageism, negative ageism, contact with older adults, and sex were significant predictors. Educational efforts aimed at addressing beliefs about ageing and older adults may contribute to further comfort in working with older adults.  相似文献

Individual variations in the way people respond to sensory stimuli can sometimes lead to maladaptive representations of the world. Indeed, sensory responsiveness profiles were found to be associated with mood symptoms such as depression and anxiety. The goal of the current study was to investigate whether attachment orientations can account for the relationship between sensory responsiveness profiles and anxiety symptoms. Participants (N = 194) completed a battery of questionnaires assessing sensory responsiveness profiles, attachment orientations, and anxiety symptoms. As expected, various associations between sensory responsiveness profiles and anxiety symptoms were accounted for by attachment anxiety and avoidance. We suggest a possible causal path, in which early‐developing sensory responsiveness profiles lead to attachment insecurities, which in turn may lead to mood symptoms such as anxiety.  相似文献

The value and function of self‐analysis has been a contentious issue in several studies dedicated to the Freudian legacy. For some writers, Freud's experience of self‐analysis is rightly considered to be the master key to an understanding of the origins of the fundamentals of psychoanalysis. For others, the exaggerated importance attributed to the process merely led to the construction of a foundational myth. Nevertheless, if it is recognized to be a process in which Freud, in collaboration with Fliess, analysed personal aspects, working hypotheses and psychopathological debates, a reconsideration of self‐analysis may contribute new elements to our understanding of the paths that were taken in the elaboration of the theory and practice of pyschoanalysis. Starting from this premise, the present work will consider the systematic examination that Freud conducted of his own phobia in the course of his self‐analysis to be a process of great relevance to the elaboration of the early psychoanlytic conceptualizations of anxiety, in that in the course of this process the possible role of sexuality, fantasy, memory and unconscious determinism in the etiology of anxiety became part of the discussion.  相似文献

Both psychological stress and predictive signals relating to expected sensory input are believed to influence perception, an influence which, when disrupted, may contribute to the generation of auditory hallucinations. The effect of stress and semantic expectation on auditory perception was therefore examined in healthy participants using an auditory signal detection task requiring the detection of speech from within white noise. Trait anxiety was found to predict the extent to which stress influenced response bias, resulting in more anxious participants adopting a more liberal criterion, and therefore experiencing more false positives, when under stress. While semantic expectation was found to increase sensitivity, its presence also generated a shift in response bias towards reporting a signal, suggesting that the erroneous perception of speech became more likely. These findings provide a potential cognitive mechanism that may explain the impact of stress on hallucination‐proneness, by suggesting that stress has the tendency to alter response bias in highly anxious individuals. These results also provide support for the idea that top‐down processes such as those relating to semantic expectation may contribute to the generation of auditory hallucinations.  相似文献

The objective of this study was to extend the probability of treatment benefit method by adding treatment condition as a stratifying variable, and illustrate this extension of the methodology using the Child and Adolescent Anxiety Multimodal Study data. The probability of treatment benefit method produces a simple and practical way to predict individualized treatment benefit based on pretreatment patient characteristics. Two pretreatment patient characteristics were selected in the production of the probability of treatment benefit charts: baseline anxiety severity, measured by the Pediatric Anxiety Rating Scale, and treatment condition (cognitive-behavioral therapy, sertraline, their combination, and placebo). We produced two charts as exemplars which provide individualized and probabilistic information for treatment response and outcome to treatments for child anxiety. We discuss the implications of the use of the probability of treatment benefit method, particularly with regard to patient-centered outcomes and individualized decision-making in psychology and psychiatry.  相似文献

Most of us have settled views about various intellectual debates, and much of the activity of philosophers is devoted to giving arguments that are designed to convince one's opponents to change their minds about a certain issue. But, what might this process require? More pointedly, can you clearly imagine what it would take to make you change your mind about a position you currently hold? This article argues that the surprising answer to this question is no—you cannot imagine what would convince you to change your mind, since in doing so you would actually have to find those reasons compelling. The article then briefly looks at some implications of this conclusion.  相似文献

An atypical subgroup of Social Anxiety Disorder (SAD) with impulsive rather than inhibited traits has recently been reported. The current study examined whether such an atypical subgroup could be identified in a clinical population of 84 adults with SAD. The temperament dimensions harm avoidance and novelty seeking of the Temperament and Character Inventory, and the Liebowitz Social Anxiety Scale were used in cluster analyses. The identified clusters were compared on depressive symptoms, the character dimension self‐directedness, and treatment outcome. Among the six identified clusters, 24% of the sample had atypical characteristics, demonstrating mainly generalized SAD in combination with coexisting traits of inhibition and impulsivity. As additional signs of severity, this group showed low self‐directedness and high levels of depressive symptoms. We also identified a typically inhibited subgroup comprising generalized SAD with high levels of harm avoidance and low levels of novelty seeking, with a similar clinical severity as the atypical subgroup. Thus, higher levels of harm avoidance and social anxiety in combination with higher or lower levels of novelty seeking and low self‐directedness seem to contribute to a more severe clinical picture. Post hoc examination of the treatment outcome in these subgroups showed that only 20 to 30% achieved clinically significant change.  相似文献
