The topic of transitions in automated driving is becoming important now that cars are automated to ever greater extents. This paper proposes a theoretical framework to support and align human factors research on transitions in automated driving. Driving states are defined based on the allocation of primary driving tasks (i.e., lateral control, longitudinal control, and monitoring) between the driver and the automation. A transition in automated driving is defined as the process during which the human-automation system changes from one driving state to another, with transitions of monitoring activity and transitions of control being among the possibilities. Based on ‘Is the transition required?’, ‘Who initiates the transition?’, and ‘Who is in control after the transition?’, we define six types of control transitions between the driver and automation: (1) Optional Driver-Initiated Driver-in-Control, (2) Mandatory Driver-Initiated Driver-in-Control, (3) Optional Driver-Initiated Automation-in-Control, (4) Mandatory Driver-Initiated Automation-in-Control, (5) Automation-Initiated Driver-in-Control, and (6) Automation-Initiated Automation-in-Control. Use cases per transition type are introduced. Finally, we interpret previous experimental studies on transitions using our framework and identify areas for future research. We conclude that our framework of driving states and transitions is an important complement to the levels of automation proposed by transportation agencies, because it describes what the driver and automation are doing, rather than should be doing, at a moment of time. 相似文献

Discourse describing evolution in contemporary popular science writing often posits that humans evolved not from an ape, but from a merely ape-like or generalized primate. Contemporary fossil and genetic evidence, though, have revealed what can accurately be described as an extinct ape species as ancestral to the human lineage. The persistence of ambiguous terms in popular science writing may be interpreted as a form of anthropocentric rhetorical discourse. Nonetheless, while such discourse is often justified in terms of increasing the public understanding of science, it may also mitigate (whether consciously intended or not) religion-based resistance to evolutionary theory. 相似文献

The prospective study examines which factors assessed in pregnancy predispose mothers to seeing their newborn crying more as a problem and to more mental health problems in response to excessive baby crying. A total of 2140 pregnant women participated in the study, of which 1798 delivered a living singleton. Data was collected by means of a series of written questionnaires. The duration of the baby crying as well as the maternal reactions to the crying were assessed at a mean time of 1–2 months following delivery. The maternal reactions were related to several variables assessed at the end of the first trimester of pregnancy. Data was analysed by means of the method of stepwise multiple regression. Four factors were found to be associated with the reactions of mothers to newborn crying. These are: the duration of the crying, a first-born baby, a relatively high maternal age, and a relatively high score on ‘neuroticism’ in mothers. It was concluded that it is possible to indicate to a certain degree which mothers of excessive crying babies are prone to report more impact of the crying or more mental health symptomatology. It might be worthwhile to offer those mothers some extra support in order to try to prevent the situation from becoming worse. © 1998 John Wiley & Sons, Ltd. 相似文献

Imitation of tongue protrusions and mouth openings was investigated in 18 newborn infants using a procedure differing in three ways from previous laboratory studies: the mother presented the target gestures, she was permitted to adjust to the infant's reactions, and the infant's baseline response rate was assessed during face-to-face interaction. This procedure was assumed to facilitate infant imitation. Compared with baseline responses in face-to-face interaction, both tongue protrusions and mouth openings were imitated in the two conditions. No imitation, however, was found when the responses in the two imitation conditions were compared. These results are less convincing than those found in strictly controlled laboratory experiments. A less restrictive procedure did not, therefore, promote imitation. The mixed results could be explained by too short an exposure to the target gesture. If repeated and insistent gesturing is a crucial condition, neonatal imitation might be understood to be the result of instruction and teaching, rather than a means of mutual communication. © 1998 John Wiley & Sons, Ltd. 相似文献

Postural control asymmetry is an important aspect of Parkinson’s disease (PD) that may be associated with falls. The aim of this study was to compare the postural control asymmetry during postural tasks between fallers and non-fallers in people with PD and neurological healthy age-matched controls (CG). Individuals with idiopathic PD (n = 24) and CG (n = 24) were sub-divided into groups of fallers and non-fallers based on their fall history over the past year. Participants performed blocks of three 30-s trials of quiet standing with feet in a side-by-side and semi-tandem stance position. The center of pressure parameters for each limb were measured and used to calculate the symmetry index. Fallers compared to non-fallers had decreased asymmetry of vertical force in the side-by-side condition. During the tandem-front leg condition, PD non-fallers increased asymmetry of the medial-lateral velocity of sway compared to CG non-fallers. In addition, for the tandem–back leg condition, PD non-fallers increased asymmetry of total displacement and medial-lateral root mean square and mean velocity of sway compared to PD fallers. The results of the study did not support the hypothesis that PD fallers are more asymmetric than PD non-fallers. On the contrary, our results indicated that PD non-fallers had higher postural control asymmetry, especially during the more challenging (semi-tandem standing) postural task. 相似文献

Human Library is a public event aimed at reducing stereotypes and prejudices, in the form of an interactive, contact‐based intervention. It employs the logic of a regular library yet with readers “borrowing” Living Books, which are real people representing various minority groups. Readers engage in 30‐min conversations, during which they can challenge their stereotypes and widen their scope of knowledge and understanding. This pre‐post intervention study examined the effectiveness of the Human Library (held in Wroc?aw, Poland) in reducing social distance towards Roma, Muslims, dark‐skinned, and transgender people, as well as in decreasing homonegativity. Also, we measured whether participation in the Human Library changes individual attitudes towards diverse workgroups. We found that the Human Library decreased social distance towards Muslims. Also, the more Living Books that the participants “read,” the bigger the shift in their social distance towards Muslims. Furthermore, we observed an increase in positive affective attitude towards working in diversified groups, as a result of participation in the event. The study serves as partial support for the effectiveness of the Human Library in altering one's attitude towards minority groups and diversity. The intervention is discussed as a promising but not yet entirely understood tool to improve intergroup relations. 相似文献

People are becoming more and more humanized in the process of understanding the law. According to the right to discipline, the law has its own core setting factors, while some limits can't reach people's desire. Therefore, the legal and illegal mode of transcending rights is very important. In order to analyze the legal form of modern rights, in this paper, the cognitive learning and memory process of human brain were simulated through the artificial neural network and the understanding of human brain structure, and the role of law, discipline and governance was reflected. In the study, the structure and algorithm of the model neural network were optimized, the memory forgetting curve mechanism that can simulate the human brain was introduced, and thus the network recognition rate was improved. And in the algorithm, the calculation of matching degree was avoided, and the computational complexity was reduced to the sample. Then the sample was compared with the SOM, ART1, and PNN algorithms. The experimental simulation results show that the recognition speed of this sample is 1.9 times faster than that of ART1, 58 times than that of SOM, and 1.5 times than that of the PNN network. 相似文献

Much previous research has examined various aspects of auditory processing, including the localization of sounds, and the influence of lexical and indexical information on language processing. In the present set of experiments we explored the ability of listeners to estimate the number of speakers in a group solely from the information in an auditory signal. The bound on accurately estimating the number of simultaneous speakers is 3. We suggest that subitization—the ability to estimate numerosity of visual and auditory elements without explicitly counting these elements—rather than the capacity of short-term memory, may underlie this limitation. The cognitive constraint on estimating the number of simultaneous speakers may have implications for a wide variety of seemingly unrelated psychological phenomena. 相似文献

While economic downturns have adverse effects on young people's life chances, empirical studies examining whether and to what extent human values, social attitudes and well‐being indicators respond to sudden economic shocks are scarce. To assess the claim that human values are less affected by economic shocks than social attitudes and well‐being, two distinct yet related studies based on the European Social Survey (ESS) are conducted. The first employs a fixed effects pseudo‐panel analysis of the 2008–2014 ESS‐waves to detect whether changes over time in the socio‐demographic group's unemployment risk and national youth unemployment affect individual dispositions to varying degrees. The second study captures micro‐ and cross‐national effects in the 2010 ESS cross‐section. Unique for this set‐up is that we can test whether the findings hold for over‐time changes in youth unemployment within countries (pseudo‐panel), as well as for cross‐country differences in youth unemployment (multilevel). Both studies indicate that political trust, satisfaction with the economy and subjective well‐being are lowered by economic risk and hardship, while social trust and self‐rated health are less affected by changes in youth unemployment. Secondly, human values are immune to economic risk, underscoring that values transcend specific situations and are therefore resistant against sudden economic shocks. 相似文献
