Physiological indicators of driver workload during car-following scenarios and takeovers in highly automated driving

This driving simulator study, conducted as a part of Horizon2020-funded L3Pilot project, investigated how different car-following situations affected driver workload, within the context of vehicle automation. Electrocardiogram (ECG) and electrodermal activity (EDA)-based physiological metrics were used as objective indicators of workload, along with self-reported workload ratings. A total of 32 drivers were divided into two equal groups, based on whether they engaged in a non-driving related task (NDRT) during automation (SAE Level 3) or monitored the drive (SAE Level 2). Drivers in both groups were exposed to two counterbalanced experimental drives, lasting ∼ 18 min each, of Short (0.5 s) and Long (1.5 s) Time Headway conditions during automated car-following (ACF), which was followed by a takeover that happened with or without a lead vehicle. Results showed that driver workload due to the NDRT was significantly higher than both monitoring the drive during ACF and manual car-following (MCF). Furthermore, the results indicated that a lead vehicle maintain a shorter THW can significantly increase driver workload during takeover scenarios, potentially affecting driver safety. This warrants further research into understanding safe time headway thresholds to be maintained by automated vehicles, without placing additional cognitive or attentional demands on the driver. Our results indicated that ECG and EDA signals are sensitive to variations in workload, which warrants further investigation on the value of combining these two signals to assess driver workload in real-time, to help future driver monitoring systems respond appropriately to the limitations of the driver, and predict their performance in the driving task, if and when they have to resume manual control of the vehicle after a period of automated driving.     

Affective atmospheres of weapons technologies: The case of battle drones,combat fighters and bodies in contemporary German geopolitics

Using the example of the defense and security sector at the Innovation and Leadership in Aerospace aviation fair in Berlin, this paper interrogates how the presentation of weapons technologies at German security and aviation fairs produces a/effects that influence the body and serve to legitimize political decisions. It examines to what extent the body becomes the site of geopolitical negotiation via affective atmospheres and how different scales interact within this process. First, I argue that affective connections between weapons technologies and spectators are essential for legitimizing warfare technologies. Second, I argue that affects of weapons technologies are subject to ambivalence and ambiguity, and that they are to be understood as entangled with other affects in the same body. Third, I argue that affects become effective across material and spatial scales. Drawing on geographic work on affective atmospheres, debates in intimate geopolitics and feminist science and technology studies, the paper contributes to critical geopolitics by unpacking the role of affective dimensions in naturalizing the development and acquisition of weapons technologies. In doing so, it also contributes to debates on the methodological operationalization of theories of affect and to emotional geographies of (in)security.     

Between place and territory: Young people's emotional geographies of security and insecurity in Brussels' deprived areas

While much of literature on place attachment describes it as an affective bond between a (young) person and place, with positive psychosocial consequences such as identification, rootedness and belonging, some authors are cautious and stress that an enhanced attachment to place, termed “territoriality”, may have negative consequences such as hostility towards outsiders and a sense of non-belonging elsewhere. In this paper, I ask how we should understand this difference and how the analysis of young people's emotional geographies of (in)security can bring light to this question. The paper finds that emotional geographies of (in)security are instrumental in understanding how a “positive” attachment to place may lead to a “negative” attachment to territory, how some young people emotionally attach to places and some are inclined to claim these places against outsiders (and also at the expense of other members of the community). This explicit appropriation of public spaces in the home neighbourhood is co-constituted by feeling secure inside and insecure outside the area. Territoriality may be a response to or an expression of ontological insecurity and of the inner unease that prompts them to strange avoidance and contorted strategies for manipulating spaces and setting boundaries designed to secure the self.     

From Copenhagen to the consulting room: Pauli and Jung in Copenhagen

In this paper the city of Copenhagen is used as a starting point to highlight some critical historical events, both concerning the exchange of ideas between the physicist Wolfgang Pauli and C.G. Jung and the history of psychotherapy in Scandinavia. Pauli's years in Copenhagen under the influence of Niels Bohr and his philosophy prepared him mentally to receiveC.G. Jung's ideas. The paper also recounts the one occasion that Jung was in Scandinavia, attending the 9th conference of the General Medical Society for Psychotherapy in Copenhagen, just before going to New York in 1937 to give his final seminars on Pauli's dreams. The reason for focusing on these particular events is that they also constitute part of the history of the reception of psychodynamic psychology in Sweden and Scandinavia.     

Indigenizing CBPR: Evaluation of a Community-Based and Participatory Research Process Implementation of the Elluam Tungiinun (Towards Wellness) Program in Alaska

The process that community based participatory research (CBPR) implementation takes in indigenous community contexts has serious implications for health intervention outcomes and sustainability. An evaluation of the Elluam Tungiinun (Towards Wellness) Project aimed to explore the experience of a Yup'ik Alaska Native community engaged within a CBPR process and describe the effects of CBPR process implementation from an indigenous community member perspective. CBPR is acknowledged as an effective strategy for engaging American Indian and Alaska Native communities in research process, but we still know very little about the experience from a local, community member perspective. What are the perceived outcomes of participation in CBPR from a local, community member perspective? Qualitative methods were used to elicit community member perspectives of participation in a CBPR process engaged with one Yup'ik community in southwest Alaska. Results focus on community member perceptions of CBPR implementation, involvement in the process and partnership, ownership of the project with outcomes observed and perceived at the community, family and individual levels, and challenges. A discussion of findings demonstrates how ownership of the intervention arose from a translational and indigenizing process initiated by the community that was supported and enhanced through the implementation of CBPR. Community member perspectives of their participation in the research reveal important process points that stand to contribute meaningfully to implementation science for interventions developed by and for indigenous and other minority and culturally diverse peoples.     

Randomized controlled trial of parental responsiveness intervention for toddlers at high risk for autism

This study tested the effects of a parent-mediated intervention on parental responsiveness with their toddlers at high risk for an autism spectrum disorder (ASD).Participants included caregivers and their 66 toddlers at high risk for ASD. Caregivers were randomized to 12 sessions of an individualized parent education intervention aimed at improving parental responsiveness or to a monitoring control group involving 4 sessions of behavioral support. Parental responsiveness and child outcomes were measured at three time points: at beginning and end of the 3-month treatment and at 12-months post-study entry. Parental responsiveness improved significantly in the treatment group but not the control group. However, parental responsiveness was not fully maintained at follow up. There were no treatment effects on child outcomes of joint attention or language. Children in both groups made significant developmental gains in cognition and language skills over one year. These results support parental responsiveness as an important intervention target given its general association with child outcomes in the extant literature; however, additional supports are likely needed to fully maintain the treatment effect and to affect child outcomes.     

High cognitive sensitivity to activational effects of testosterone in parents of offspring with autism spectrum disorders

The existence of mild forms of autistic-like characteristics in parents of children with autism spectrum disorders (ASDs) has been defined as a broader autistic phenotype (BAP). Excessive prenatal exposure to testosterone (T) seems to play a role in its development. The aims of this study were to characterize whether ASD parents show masculinized brains or high T prenatal exposure compared to a normative population, using cognitive questionnaires, and also to examine the T level changes in response to different cognitive tasks. ASD parents were found to present higher autistic and lower empathic trait scores than controls. They also have higher T levels and magnitude of T response to cognitive tasks. Specific correlation patterns between masculinized brain types and T levels were observed only in ASD parents. Thus, it seems that first-degree relatives of people with ASD have high T levels during task performance, which, in turn, produce slight cognitive masculinization. Our findings should be considered for understanding the role of androgens in the etiology of ASD. Nevertheless, the masculinization parameters described throughout the study are subtle and require further analysis.     

Developmental plateau in visual object processing from adolescence to adulthood in autism

A lack of typical age-related improvement from adolescence to adulthood contributes to face recognition deficits in adults with autism on the Cambridge Face Memory Test (CFMT). The current studies examine if this atypical developmental trajectory generalizes to other tasks and objects, including parts of the face. The CFMT tests recognition of whole faces, often with a substantial delay. The current studies used the immediate memory (IM) task and the parts-whole face task from the Let’s Face It! battery, which examines whole faces, face parts, and cars, without a delay between memorization and test trials. In the IM task, participants memorize a face or car. Immediately after the target disappears, participants identify the target from two similar distractors. In the part-whole task, participants memorize a whole face. Immediately after the face disappears, participants identify the target from a distractor with different eyes or mouth, either as a face part or a whole face.Results indicate that recognition deficits in autism become more robust by adulthood, consistent with previous work, and also become more general, including cars. In the IM task, deficits in autism were specific to faces in childhood, but included cars by adulthood. In the part-whole task, deficits in autism became more robust by adulthood, including both eyes and mouths as parts and in whole faces. Across tasks, the deficit in autism increased between adolescence and adulthood, reflecting a lack of typical improvement, leading to deficits with non-face stimuli and on a task without a memory delay. These results suggest that brain maturation continues to be affected into adulthood in autism, and that the transition from adolescence to adulthood is a vulnerable stage for those with autism.
