Bio-inspired intent communication for automated vehicles

Various external human-machine interfaces (eHMIs) have been proposed that communicate the intent of automated vehicles (AVs) to vulnerable road users. However, there is no consensus on which eHMI concept is most suitable for intent communication. In nature, animals have evolved the ability to communicate intent via visual signals. Inspired by intent communication in nature, this paper investigated three novel and potentially intuitive eHMI designs that rely on posture, gesture, and colouration, respectively. In an online crowdsourcing study, 1141 participants viewed videos featuring a yielding or non-yielding AV with one of the three bio-inspired eHMIs, as well as a green/red lightbar eHMI, a walk/don’t walk text-based eHMI, and a baseline condition (i.e., no eHMI). Participants were asked to press and hold a key when they felt safe to cross and to answer rating questions. Together, these measures were used to determine the intuitiveness of the tested eHMIs. Results showed that the lightbar eHMI and text-based eHMI were more intuitive than the three bio-inspired eHMIs, which, in turn, were more intuitive than the baseline condition. An exception was the bio-inspired colouration eHMI, which produced a performance score that was equivalent to the text-based eHMI when communicating ‘non-yielding’. Further research is necessary to examine whether these observations hold in more complex traffic situations. Additionally, we recommend combining features from different eHMIs, such as the full-body communication of the bio-inspired colouration eHMI with the colours of the lightbar eHMI.     

When ignorance is no excuse: Different roles for intent across moral domains

A key factor in legal and moral judgments is intent. Intent differentiates, for instance, murder from manslaughter. Is this true for all moral judgments? People deliver moral judgments of many kinds of actions, including harmful actions (e.g., assault) and purity violations (e.g., incest, consuming taboo substances). We show that intent is a key factor for moral judgments of harm, but less of a factor for purity violations. Based on the agent’s innocent intent, participants judged accidental harms less morally wrong than accidental incest; based on the agent’s guilty intent, participants judged failed attempts to harm more morally wrong than failed attempts to commit incest. These patterns were specific to moral judgments versus judgments of the agent’s control, knowledge, or intent, the action’s overall emotional salience, or participants’ ratings of disgust. The current results therefore reveal distinct cognitive signatures of distinct moral domains, and may inform the distinct functional roles of moral norms.     

Forming and reacting to overall fairness: A cross-cultural comparison

This study compared the cross-cultural formation and reactions toward overall fairness perception of employees from the US, China, Korea, and Japan. Distributive justice was related to overall fairness less strongly for Americans and Japanese than for Chinese and Koreans. In contrast, interactional justice was related to overall fairness more strongly for Americans and Japanese than for Chinese and Koreans. As expected, materialism seems to provide a coherent account of these cultural differences. In addition, overall fairness showed a stronger effect on turnover intention for Americans than for Chinese and Koreans. For job satisfaction, the effect of overall fairness was stronger for Americans than for Chinese, Koreans, and Japanese. Power distance seems to provide an adequate account of these cultural differences.     

Communicating intent to develop shared situation awareness and engender trust in human-agent teams

This paper addresses issues related to integrating autonomy-enabled, intelligent agents into collaborative, human-machine teams. Interaction with intelligent machine agents capable of making independent, goal-directed decisions in human-machine teaming operations constitutes a major change from traditional human-machine interaction involving teleoperation. Communicating the machine agent’s intent to human counterparts becomes increasingly important as independent machine decisions become subject to human trust and mental models. The authors present findings from their research that suggest existing user display technologies, tailored with context-specific information and the human’s knowledge level of the machine agent’s decision process, can mitigate misperceptions of the appropriateness of agent behavioral responses. This is important because misperceptions on the part of human team members increases the likelihood of trust degradation and unnecessary interventions, ultimately leading to disuse of the agent. Examples of possible issues associated with communicating agent intent, as well as potential implications for trust calibration are provided.

Children’s Intent Attributions and Feelings of Distress: Associations with Maternal and Paternal Parenting Practices

Many studies point to the importance of social information processing mechanisms in understanding distinct child behaviors such as aggression. However, few studies have assessed whether parenting might be related to such mechanisms. This study considers how aversive forms of parenting (i.e., corporal punishment, psychological control) as well as parental warmth and responsiveness might be concurrently associated with children’s hostile intent attributions and emotional distress in response to ambiguous provocation scenarios (both instrumental and relational). A sample of 219 children (101 boys, 118 girls) and their parents participated. Bivariate associations showed that parenting dimensions and child variables were significantly associated in mostly expected ways, but only in father–child relationships (especially father–son relationships). Analyses generally showed dimensions of aversive parenting by fathers to be associated with a greater tendency toward hostile attributional bias in children. Moreover, paternal warmth and responsiveness, as well as corporal punishment, were associated with less emotional distress in boys. In contrast, paternal psychological control predicted greater emotional distress in boys. The findings suggest that the tone of the father–son relationship, in particular, may help set the tone for how boys interpret their social world. Psychological control figures prominently in this regard.     

Designing volunteers’ tasks to maximize motivation,satisfaction and performance: The impact of job characteristics on volunteer engagement

We conducted a field study to test the applicability of the job characteristics model (JCM) in volunteer organizations and examine the impact of job characteristics on volunteer motivation, satisfaction and intent to quit, as well as test a measure of volunteer performance. One hundred and twenty-four volunteers completed measures of job characteristics, motivation, satisfaction, and intent to quit. Supervisors rated volunteer task performance and organizational citizenship behaviors (OCB). Results showed that job characteristics were related to volunteers’ autonomous motivation, satisfaction and performance. Autonomous motivation acted as a mediator in the relationship between job characteristics and satisfaction. The theoretical and practical implications of these findings are discussed.

Un examen empirique de l’intention de quitter des millénariaux à travers diverses dimensions de l’adéquation individu/environnement

The purpose of this paper is to examine the simultaneous effect of three person-environment fit dimensions, namely person-organization fit, person-group fit and person-supervisor fit on the millennials’ intent to leave. Data were collected among a sample of 178 employees born after 1980 working in Quebec organizations from various industries. Results indicate that the three person-environment fit dimensions are linked to intent to leave, but that only person-organization fit has an effect on intent to leave.     

Public opinion on automated driving: Results of an international questionnaire among 5000 respondents

This study investigated user acceptance, concerns, and willingness to buy partially, highly, and fully automated vehicles. By means of a 63-question Internet-based survey, we collected 5000 responses from 109 countries (40 countries with at least 25 respondents). We determined cross-national differences, and assessed correlations with personal variables, such as age, gender, and personality traits as measured with a short version of the Big Five Inventory. Results showed that respondents, on average, found manual driving the most enjoyable mode of driving. Responses were diverse: 22% of the respondents did not want to pay more than $0 for a fully automated driving system, whereas 5% indicated they would be willing to pay more than $30,000, and 33% indicated that fully automated driving would be highly enjoyable. 69% of respondents estimated that fully automated driving will reach a 50% market share between now and 2050. Respondents were found to be most concerned about software hacking/misuse, and were also concerned about legal issues and safety. Respondents scoring higher on neuroticism were slightly less comfortable about data transmitting, whereas respondents scoring higher on agreeableness were slightly more comfortable with this. Respondents from more developed countries (in terms of lower accident statistics, higher education, and higher income) were less comfortable with their vehicle transmitting data, with cross-national correlations between ρ = −0.80 and ρ = −0.90. The present results indicate the major areas of promise and concern among the international public, and could be useful for vehicle developers and other stakeholders.     

Brands as intentional agents framework: How perceived intentions and ability can map brand perception

Building on the Stereotype Content Model, this paper introduces and tests the Brands as Intentional Agents Framework. A growing body of research suggests that consumers have relationships with brands that resemble relations between people. We propose that consumers perceive brands in the same way they perceive people. This approach allows us to explore how social perception theories and processes can predict brand purchase interest and loyalty. Brands as Intentional Agents Framework is based on a well-established social perception approach: the Stereotype Content Model. Two studies support the Brands as Intentional Agents Framework prediction that consumers assess a brand's perceived intentions and ability and that these perceptions elicit distinct emotions and drive differential brand behaviors. The research shows that human social interaction relationships translate to consumer–brand interactions in ways that are useful to inform brand positioning and brand communications.
