识解水平对跨期选择和风险选择的影响

通过考察识解水平启动对跨期选择和风险选择的影响, 探究两类选择对时间或风险心理加工的相似性。结果发现, 无论以思维诱导为识解水平的启动条件(实验1), 还是以视觉加工为识解水平的启动条件(实验2), 受高识解水平启动的被试对延迟选项和风险选项的主观值判断都要大于受低识解水平启动的被试, 说明跨期选择中的延迟时间和风险选择中的概率具有相似的表征, 而识解水平思维定势是通过影响金额和时间(或概率)的相对权重起作用。即由于高识解水平下的金额权重高于低识解水平, 时间(或概率)权重低于低识解水平, 从而使被试在高识解水平下更愿意等待或冒险。

The influence of alcohol (0.5‰) on the control and manoeuvring level of driving behaviour,finding measures to assess driving impairment: A simulator study

ObjectiveThe influence of psychoactive substances on driving performance and traffic safety has been extensively studied. Research on the influence of alcohol at the control level of behaviour (i.e. automated processes) has been well established and has shown that the ability to operate a vehicle decreases with rising alcohol levels. However, results one level higher at the manoeuvring level (i.e. conscious processes), are inconsistent. The current study aimed to replicate findings on the influence of alcohol on the control level of behaviour and investigate effects on the manoeuvring level in order to find suitable measures to assess driving impairment.MethodThe study was double-blind, placebo-controlled with a counterbalanced treatment order and a two-way crossover design. Thirty participants performed tasks in a driving simulator under the influence of alcohol (0.5‰) and a placebo. In the driving tasks the control level of behaviour (swerving, average speed, and speed variation) was investigated, as well as the manoeuvring level of behaviour (distance to other traffic during an overtaking manoeuvre, reaction time to a traffic light turning amber, and response to a suddenly merging car).ResultsAs expected, alcohol affected the control level of behaviour negatively. Participants swerved more and showed more speed variation after alcohol intake. The manoeuvring level of driving behaviour was also affected by alcohol. The distance to other drivers during an overtaking manoeuvre was smaller under the influence of alcohol. Results on reaction time were however less straightforward. Reaction time increased significantly under the influence of alcohol when reacting to a traffic light but not in reaction to a car unexpectedly merging into traffic. When analysing behaviour in reaction to these different events in more detail it became clear that they were responded to in varying manners, making it difficult to find an average impairment measure.ConclusionsThe deteriorating effect of alcohol at the control level of driving behaviour was replicated, confirming the suitability of the standard deviation of lateral position and the variation in speed as measures of impairment. At the manoeuvring level, the kept distance to the leading car during an overtaking manoeuvre appeared to be a suitable measure to assess impairment as well as reaction time to a traffic light. The current study also confirms the difficulties in evaluating complex driving behaviour and the need for more research on this subject.     

Reducing uncertainty by anticipation in traffic – The effect of situational characteristics and criticality on behavioral,subjective, and psychophysiological parameters

Uncertainty in traffic may have fatal consequences when operating a vehicle. Enabling drivers to anticipate the behavior of other traffic participants can help reduce uncertainty and thus increase traffic safety. A multi-method approach using behavioral, subjective, and psychophysiological measures was applied to investigate the relation of uncertainty and anticipation. Participants (N = 30) observed simulated, video-based urban traffic scenarios while skin conductance responses were recorded. They had to indicate, by pressing a button, (1) the moment they first thought another vehicle might merge into their lane (low certainty anticipation) and (2) the moment they were sure another vehicle would merge (high certainty anticipation). Situational characteristics served as anticipatory cues that helped predict the other vehicle’s action. On the one hand, in this study, target cues (which are clearly related to the target’s activity) served to indicate an imminent lane change. On the other hand, context cues represented visible precursors in the traffic environment, e.g. a traffic sign pointing to upcoming road work. In addition, causal cues were used to determine a reason for the other vehicle to change lanes (in this instance, a construction site blocking the lane). These situational characteristics, as well as the situational criticality, were manipulated to gain insights into factors influencing the process of anticipation. Results offered an effect of target cue moderated by criticality: especially in more critical situations, the anticipation rate and subjective certainty increased, and physiological activation was reduced with target cues. Overall, the anticipatory performance was found to be a predictor of subjective certainty (through its impact on skin conductance responses). The findings are discussed in the context of the methodological approach for applications in traffic.     

Proposal of a driver profile classification in relation to risk level in overtaking maneuvers

Traffic crashes are a worldwide problem, and records have indicated frontal collisions have resulted in the most significant number of fatalities. Such a type of crash is frequently caused by improper overtaking of vehicles, which highlights the interference of human factors. Therefore, investigations on driver's risk perception are necessary. This study proposes a classification of driver's risk level through a decision tree using the Classification and Regression Tree (CART) algorithm from data collected from the overtaking maneuvers in a driving simulator. The model obtained by CART algorithm indicated young male drivers are more likely to take risks in overtaking maneuvers. The results were correlated with governmental records and similar studies. In addition, the results showed the potential of the tool for used as a risk level classifier, as well as the validation of the driving simulator in studies associated with human factor behaviours, accident analysis and investigation.     

Uprooted minds: displacement,trauma and dissociation

The author, English born and living in Sydney, Australia, presents an argument for the usefulness of the recognition of the implicit simultaneous links between the following:

• development of psychic skin and the establishment of the body schema
• development of a sense of identity
• relationship with place

such that the formulation psychic skin< > mind < > body < > self < > place < > world can be thought of as an organising gestalt or implicit continuum of ‘skin’ experience and process upon which the explicit always depends. This constitutes a taken‐for‐granted ground‐plan of the self‐in‐place . The author follows this with an exploration of the consequences for psychic health of a traumatic rupture of this gestalt for both individual and group. Material from two cases is presented: first, a young woman whose family fled the Balkan wars which splintered the former Yugoslavia; second, the transmission of displacement trauma into the third generation of a family who arrived in Australia after WW II from the former Yugoslavia. For the purposes of this paper I will not make a distinction between migrants/exiles/refugees and instead refer to either displacement or dislocation.

A study of the compliance level of connected vehicle warning information in a fog warning system based on a driving simulation

The accidents in the freeway are frequent and more serious on foggy days. Connected vehicle (CV) technology as a new technology can inform drivers of fog conditions in advance so the drivers can adjust their driving behaviors through Human Machine Interface (HMI) and Dynamic Message Sign (DMS) in the fog warning system. The level of driver's compliance with a fog warning system is the key to assessing the effectiveness of the fog warning system. To evaluate the compliance level of fog warning system, the study established a CV system testing platform based on driving simulator, and analyzed the changes in driving behavior and influencing factors for drivers under three different visibility conditions (No fog, light fog and heavy fog) based on the platform, finally, comprehensive evaluation of the optimal fog warning system under different foggy conditions based on the compliance level were made. Research indicators are divided into three aspects: 1) the response degree, including the mean speed, the minimum speed in the fog zone, the difference of the speeds when entering and leaving the fog zone, the proportion of speed following, and the speed reduction proportion prompt; 2) the response start time, which is the time to start slowing down to the speed limit; and 3) the response time duration, namely, the time in which the speed limit is followed. The results show that the response degree of the driver to the fog warning system is high, the fog warning system can effectively reduce the driving speed of the drivers and improve the speed following proportion of the drivers, the deceleration ratio of the driver at each warning point is relatively high, and the influencing factors of various indicators are complex but are mostly related to visibility and technical level. Comprehensive evaluation results show that the warning mode of the combined HMI and DMS has the highest level of compliance under light fog conditions, and when fog concentration increases, compliance level of fog warning system with HMI only is higher than others. The study establishes a reference platform for CV system and provides methods and index system for the compliance level of CV research.
