Action representations activated by task‐irrelevant information: Is it really irrelevant?

Accessing action knowledge is believed to rely on the activation of action representations through the retrieval of functional, manipulative, and spatial information associated with objects. However, it remains unclear whether action representations can be activated in this way when the object information is irrelevant to the current judgment. The present study investigated this question by independently manipulating the correctness of three types of action‐related information: the functional relation between the two objects, the grip applied to the objects, and the orientation of the objects. In each of three tasks in Experiment 1, participants evaluated the correctness of only one of the three information types (function, grip or orientation). Similar results were achieved with all three tasks: “correct” judgments were facilitated when the other dimensions were correct; however, “incorrect” judgments were facilitated when the other two dimensions were both correct and also when they were both incorrect. In Experiment 2, when participants attended to an action‐irrelevant feature (object color), there was no interaction between function, grip, and orientation. These results clearly indicate that action representations can be activated by retrieval of functional, manipulative, and spatial knowledge about objects, even though this is task‐irrelevant information.     

特征整合与加工深度对道德概念容器隐喻联结的影响

提出了隐喻提取假说将隐喻联结的形成和提取进行分离, 并通过3个实验探究了道德概念与容器空间的隐喻联结及其受知觉加工深度和特征整合程度的影响。实验1采用空间Stroop范式, 实验2a和实验2b均采用启动范式, 实验3a和实验3b均采用加入任务要求的Stroop范式。结果发现：(1)在经典Stroop范式中未发现道德概念与容器空间的隐喻联结; (2)在启动范式中发现, 较深知觉加工深度下道德概念与容器空间存在较弱的隐喻联结; (3)在较高特征整合程度的Stroop任务中, 道德概念与容器空间存在较强的隐喻联结。结果表明：道德概念与容器空间存在道德为内、不道德为外的隐喻联结, 这种隐喻联结在映射上表现为双向性, 并且受到特征整合程度和知觉加工深度的影响, 同时也为隐喻提取假说提供了证据支持。     

情感事件理论的内容、应用及研究展望

组织中的情绪情感研究逐渐成为了学界关注的热点, 情感事件理论的出现为该领域研究提供了一个整合的框架。情感事件理论认为员工在工作中的情感反应由特定的工作事件引发, 这些情感反应会进一步影响员工的态度与行为。该理论区分了情感反应与工作满意度的差异, 并在对工作满意度解构的基础上提出了情感驱动型和判断驱动型两类不同性质的行为。情感事件理论对研究组织成员情感反应的作用机制具有重要的指导意义, 但另一方面它也需考虑团体层次情感机制及测量方法等因素, 在更加具体的情境中进一步验证和完善。

Are novice drivers competent to take over control from level 3 automated vehicles? A comparative study with experienced drivers

With level 3 automated vehicles poised to appear on the roads soon, takeover remains a major challenge. At present, the effect of manual driving experience on takeover performance is unknown. Therefore, a simulator study was conducted to investigate the influence of driving experience (novice and experienced) on takeover performance in different takeover time budgets (7 s and 5 s) and in combination with a visual secondary task (i.e., surrogate reference task). Data from 48 young and middle-aged participants consisting of 24 novice and 24 experienced drivers were used for this study. Researchers found that the overall stability of evasive maneuvers by novice drivers was considerably worse than that by experienced drivers. A detailed analysis showed that the influence of driving experience on takeover stability was mainly reflected in longitudinal control rather than lateral control. A significant interaction between driving experience and visual secondary task showed that the latter had a substantial impact on the takeover stability of experienced drivers but not on that of novice drivers. Researchers also found that rich manual driving experience cannot make the takeover process of experienced drivers more stable than that of novice drivers under conditions of eye-off-road. In addition, no significant difference was found between novice and experienced drivers in automation disengagement time, takeover time and minimum time to collision. Results indicate that novice drivers have poor takeover stability and weak adaptability, but their longitudinal collision risk is not deteriorated by the lack of manual driving experience.     

Should older people be considered a homogeneous group when interacting with level 3 automated vehicles?

Exploring the future mobility of older people is imperative for maintaining wellbeing and quality of life in an ageing society. The forthcoming level 3 automated vehicle may potentially benefit older people. In a level 3 automated vehicle, the driver can be completely disengaged from driving while, under some circumstances, being expected to take over the control occasionally. Existing research into older people and level 3 automated vehicles considers older people to be a homogeneous group, but it is not clear if different sub-groups of old people have different performance and perceptions when interacting with automated vehicles. To fill this research gap, a driving simulator investigation was conducted. We adopted a between-subjects experimental design with subgroup of old age as the independent variable. The differences in performance, behaviour, and perception towards level 3 automated vehicles between the younger old group (60–69 years old) and older old group (70 years old and over) was investigated. 15 subjects from the younger old group (mean age = 64.87 years, SD = 3.46 years) and 24 from the older old group (mean age = 75.13 years, SD = 3.35 years) participated in the study. The findings indicate that older people should not be regarded as a homogeneous group when interacting with automated vehicle. Compared to the younger old people, the older old people took over the control of the vehicle more slowly, and their takeover was less stable and more critical. However, both groups exhibited positive perceptions towards level 3 automation, and the of older old people’s perceptions were significantly more positive. This study demonstrated the importance of recognising older people as a heterogeneous group in terms of their performance, capabilities, needs and requirements when interacting with automated vehicles. This may have implications in the design of such systems and also understanding the market for autonomous mobility.     

Human machine interface design for continuous support of mode awareness during automated driving: An online simulation

In the transition towards higher levels of vehicle automation, one of the key concerns with regards to human factors is to avoid mode confusion, when drivers misinterpret the driving mode and therewith misjudge their own tasks and responsibility. To enhance mode awareness, a clear human centered Human Machine Interface (HMI) is essential. The HMI should support the driver tasks of both supervising the driving environment when needed and self-regulating their non-driving related activities (NDRAs). Such support may be provided by either presenting continuous information on automation reliability, from which the driver needs to infer what task is required, or by presenting continuous information on the currently required driving task and allowed NDRA directly. Additionally, it can be valuable to provide continuous information to support anticipation of upcoming changes in the automation mode and its associated reliability or required and allowed driver task(s). Information that could support anticipation includes the available time until a change in mode (i.e. time budget), information on the upcoming mode, and reasons for changing to the upcoming mode. The current work investigates the effects of communicating this potentially valuable information through HMI design. Participants received information from an HMI during simulated drives in a simulated car presented online (using Microsoft Teams) with an experimenter virtually accompanying and guiding each session. The HMI either communicated on automation reliability or on the driver task, and either included information supporting anticipation or did not include such information. Participants were thinking aloud during the simulated drives and reported on their experience and preferences afterwards. Anticipatory information supported understanding about upcoming changes without causing information overload or overreliance. Moreover, anticipatory information and information on automation reliability, and especially a combination of the two, best supported understandability and usability. Recommendations are provided for future work on facilitating supervision and NDRA self-regulation during automated driving through HMI design.     

Trust of an Automatic Ground Collision Avoidance Technology: A Fighter Pilot Perspective

The present study examined the antecedents of trust among operational Air Force fighter pilots for an automatic ground collision avoidance technology. This technology offered a platform with high face validity for studying trust in automation because it is an automatic system currently being used in operations by the Air Force. Pilots (N = 142) responded to an online survey which asked about their attitudes toward the technology and assessed a number of psychological factors. Consistent with prior research on trust in automation, a number of trust antecedents were identified which corresponded to human factors, learned trust factors, and situational factors. Implications for the introduction of novel automatic systems into the military are discussed.     

The influence of visual noise in the binding of irrelevant features to responses

ABSTRACT

In order to efficiently control our actions, stimuli and responses made to them are stored and integrated into event files. This integration is not restricted to relevant stimuli. Even irrelevant stimuli or features that co-occur at responding can be integrated with the response. In the presence of only one irrelevant feature, binding effects for that feature are generally observed. In the presence of more than one irrelevant features, empirical evidence is inconsistent. The present experiments tested feature-response binding effects for irrelevant features when more than one irrelevant feature was present. In two experiments feature-response binding effects for three irrelevant features (colour, shape, and location) were tested in a block-wise manner. In each block one feature was orthogonally varied to the response while the others were held constant (Experiment 1) or always changed (Experiment 2). Significant binding effects were observed for each of three features when the other two were held constant (Exp. 1). However, when the other two features were varied, significant binding effects were only observed for colour and location, but not for shape (Exp. 2). The results suggest that strength of feature-response binding effects is influenced by the variation of simultaneously presented features.
