The use of in-vehicle touch screen devices is currently common in both military and civilian vehicles; despite this, the effects of motion on touch screen device operation within vehicles remains largely unexplored. This article describes a study that examined, using driving simulation, the influences of motion on performance, workload and usability when using a touch screen in-vehicle battle management system. Acting in the role of battle management system operator, 20 participants undertook four simulated drives, two under high motion (representative of an unsealed road) and two under normal motion (representative of a sealed road), whilst performing various battle management tasks. In the high motion condition, lower accuracy and longer task completion times were found, along with greater levels of subjective and physiological workload and lower levels of perceived device usability, when compared to the normal motion condition. The findings indicate that, compared to normal motion, the high motion condition impaired key aspects of battle management system operation. In closing, the importance of considering motion and its effects during touch screen system design is discussed. 相似文献

This paper focuses on the Swiss dual system of vocational education and training (VET), on the basis of the results of a study on VET dropouts. The adopted theoretical framework and method of analysis is the psychodynamic of work, which makes it possible to stress the specific constraints of a system that is closely related to the world of work. The various forms of suffering evoked by apprentices, as well as the strategies implemented to cope with it, are highlighted. The analyses also stress the pleasure young people can experience in VET. Between pleasure and suffering, these elements make it possible to consider both the assets and the shortcomings of this education system. 相似文献

This article introduces a new qualitative–quantitative approach to assess meaning of life. The participants described their sources of meaning and how they were interconnected. Four quantitative measures for (1) the accessibility of meaning-related knowledge, the degree of (2) differentiation and (3) elaboration of personal meaning systems, and (4) their coherence were calculated. The sample consisted of 59 theology and science students. The study tested (a) whether the structural properties of personal meaning systems predicted health and well-being, and (b) reflected different degrees of expertise in constructing meaning. Differentiation, elaboration, and coherence measures correlated with health and well-being and predicted life satisfaction. Theology students presented more differentiated, elaborated, and coherent personal meaning systems than science students. Both results indicate that assessing structural properties of personal meaning systems can be a promising new approach to measure meaning of life. 相似文献

In visual search, observers try to find known target objects among distractors in visual scenes where the location of the targets is uncertain. This review article discusses the attentional processes that are active during search and their neural basis. Four successive phases of visual search are described. During the initial preparatory phase, a representation of the current search goal is activated. Once visual input has arrived, information about the presence of target-matching features is accumulated in parallel across the visual field (guidance). This information is then used to allocate spatial attention to particular objects (selection), before representations of selected objects are activated in visual working memory (recognition). These four phases of attentional control in visual search are characterized both at the cognitive level and at the neural implementation level. It will become clear that search is a continuous process that unfolds in real time. Selective attention in visual search is described as the gradual emergence of spatially specific and temporally sustained biases for representations of task-relevant visual objects in cortical maps. 相似文献

Understanding of sensory and cognitive brain processes requires information about activation timing within and between different brain sites. Such data can be obtained by magnetoencephalography (MEG) that tracks cortical activation sequences with a millisecond temporal accuracy. MEG is gaining a well-established role in human neuroscience, complementing with its excellent temporal resolution the spatially more focused brain imaging methods. As examples of MEG's role in cognitive neuroscience, we discuss time windows related to cortical processing of sensory and multisensory stimuli, effects of the subject's own voice on the activity of their auditory cortex, timing of brain activation in reading, and cortical dynamics of the human mirror-neuron system activated when the subject views another person's movements. 相似文献

The problem of the other was one of the central problems for the founder of phenomenology, Edmund Husserl. He investigated the other as the alter ego intensively in the Fifth Cartesian Meditation, in which he introduced the conceptions of “analogical apperception' and “pairing' as fundamental forms of “passive synthesis.' Although it is no doubt Husserl who investigated the other most seriously and intensively, there is anaporiain his theory of the other. If the other is an object of ego's intentional consciousness, the other turns out to be no more than a modification of the ego. In the face of such anaporia, some phenomenologists embarked upon inquiry into the other. This paper focuses primarily on Alfred Schutz's discussion of the “other' in general and about the “stranger' in particular. 相似文献

文章以遗传论、精神动力论、学习论、特质论、社会文化及认知一情感系统理论为基础。利用系统科学中的系统论观点,对人格理论进行系统发展观分析。该观点将人格看作一个复杂的“大”系统,它包括外部系统和内部系统两部分。外部系统即外环境系统,内部系统则分为个体心理系统和个体行为系统,其核心是个体心理系统,它由认识系统、情意系统、自我系统及需要系统构成。人格的形成是内外两个系统相互作用、循环运动的结果。 相似文献

Sympathetic nervous system (SNS) activity at the time of acquisition is associated with human memory. However, rather than SNS activity per se, it may be afferent baroreflex feedback that is responsible for this effect. A pharmacological design was employed to unload (SNP, sodium nitro-prusside) and load (norepinephrine) baroreceptors. In addition to two placebo periods, epinephrine and esmolol (a peripherally acting beta1-blocker) served as control conditions for altered cardiac perception. During drug infusion blood pressure, heart rate, and perception of heartbeat were tested. Twenty-four healthy men were participated. The participants viewed emotional slides while their electromyographic eye blink responses to random noise bursts were measured (affective startle modulation paradigm) to determine potential drug impact on emotional processing. Subjects were not informed that memory testing would take place after 4 weeks. Drugs did not impact startle, thus indicating unbiased emotional processing at the time of acquisition. Norepinephrine had no effect on heartbeat perception, but improved (p = .002) recognition memory. SNP (p = .0001) increased heartbeat perception but impaired (p = .038) recognition memory. Epinephrine, on the other hand, increased heartbeat perception (p = .0001) yet did not impair but partially improve memory (effect on high arousing pictures only: p = .05). Heartbeat perception in the placebo condition did not correlate with recognition memory (p's > .5). We suggest that baroreflex unloading, with subsequent feedback activation of the SNS, impairs long-term incidental visual recognition memory in humans while baroreflex loading enhances it. Further, we propose that these memory effects are neither secondary to cardiac sensations that accompany SNS activation nor to altered emotional picture processing at the time of acquisition. 相似文献
